The VPA™: Assessment & Clinical Reasoning

Housekeeping while people arrive.

Materials to have ready:

• Participation & Reflection Guide

• A blank VPA™ protocol and the administration-fidelity checklist

• Tape measure or ruler for working distance

• A student profile you plan to assess next

Housekeeping:

• This course is procedural — pause the video and practice as you go.

• Fidelity checklist scoring happens in Module 4; have it open early.

• Polls, reflections, and self-checks do not affect your exam score.

• Keep your testing space at the standard working distance and lighting.

Read the filed learning objectives verbatim — this is the AOTA-approved wording.

Objectives:

• Administer a criterion-referenced, performance-based visual assessment protocol following standardized procedure — setup, working distance, stimulus presentation, prompting limits, and observation recording — achieving at least 90% procedural fidelity, so that findings can be used to describe a client's occupational performance.

• Select developmentally and contextually appropriate assessment conditions (age band, stimulus set, environment) for a given client and state, in writing, the two client or contextual factors that drove the selection, so that assessment conditions match the client's actual occupational context (classroom, home, clinic, work).

• Apply basal and ceiling rules and a hierarchical progression of visual performance demands during performance-based assessment, correctly identifying the stopping point and the client's achieved performance level to produce a profile that guides occupation-based intervention planning.

• Score a completed performance-based visual assessment protocol and interpret the results in terms of the occupational performance breakdown they produce, naming the visual performance factor most likely accounting for the breakdown with a written rationale for each of three case vignettes.

• Translate visual assessment findings into a written occupational performance statement that names the occupation (e.g., copying from the board, sustained silent reading, legible written output), the visual performance factor limiting it, and the observed impact on participation, meeting all three elements of the provided rubric.

• Document visual assessment results in occupational therapy scope language suitable for an IEP present-levels statement or plan of care, including at least one occupation-based measurable statement of current performance, without using terminology reserved for medical eye care or optometric vision therapy.

• Apply scope-of-practice and referral decision rules, consistent with the AOTA scope of practice and the 2025 AOTA Occupational Therapy Code of Ethics, to determine for each of five completed protocols whether the client proceeds to further occupational therapy assessment, to occupation-based intervention, or to referral for medical eye care, and justify each disposition as the next occupation-based step.

• Identify validity threats to any performance-based visual assessment — incomplete basal or ceiling, environmental deviation, fatigue, attention, and unfamiliar stimulus content — and describe in writing how each is recorded and how it constrains interpretation, so that a client's participation in reading, written work, and other daily occupations is not misjudged and occupational therapy services are not misallocated.

Explain how the session runs.

Schedule:

• Eight modules, 4.0 contact hours total

• Procedure → demonstration → practice → self-check

• Scored fidelity checklist and scenario sets

• Post-course exam, evaluation, certificate

How they participate:

• Opening poll in every module

• Think / Process / Share after each procedure block

• Three full clinical reasoning walkthroughs

• One knowledge check per module

Transition: "Why performance-based visual assessment: what norm-referenced batteries miss."

Open here. "Why Performance-Based Visual Assessment." What norm-referenced perceptual batteries do not tell you about the school day.

Say why this section matters for their caseload, then advance.

Ask the poll: "Which tool do you currently reach for when vision is the referral question?"

Options:

• A norm-referenced visual perception battery

• Clinical observation only

• A checklist I built myself

• Nothing consistent yet

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Frame the slide: "What a standard score misses."

Walk each point, one sentence each:

• A single accuracy score cannot show endurance decay across a work period.

• Item-level batteries rarely sample the occupation the referral was written about.

• Pass/fail cut scores hide the level at which performance actually breaks down.

• Observation of strategy, prompting, and error type carries the clinical signal.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: Norm-referenced batteries versus Performance-based VPA™.

Norm-referenced batteries:

• Population comparison

• Eligibility support in some settings

• Single-session snapshot

• Limited occupational context

Performance-based VPA™:

• Level-by-level breakdown point

• Endurance and rate under demand

• Error-type and strategy observation

• Direct line to goals and dosage

Ask: "Which column is your student living in right now?"

Frame the slide: "What an OT measures — and what we do not."

Walk each point, one sentence each:

• We measure performance, conditions, endurance, and occupational impact.

• We do not diagnose binocular vision disorders or recommend lenses.

• We refer in parallel whenever an ocular trigger appears.

• Every recommendation traces to a recorded score or observation.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: Already diagnosed and medically managed → OT addresses it versus Undiagnosed, unverified, unclear, or changing → refer.

Already diagnosed and medically managed → OT addresses it:

• Documented low acuity: magnification, enlarged print, working distance, seating, decluttered materials.

• Documented contrast loss: high-contrast materials, bold-line paper, reverse polarity, glare and lighting control.

• Documented field loss: systematic scanning, anchoring, line tracking, materials placed in the intact field.

• The VPA™ documents the functional limitation and the conditions under which performance breaks down.

Undiagnosed, unverified, unclear, or changing → refer:

• No comprehensive eye exam on file, or correction not worn, outgrown, or unverified.

• Assessment performance does not match the documented diagnosis.

• Anything new: new eye turn, new double vision, new field complaint, sudden change, pain.

• Referral is the action for these — OT addresses acuity, contrast, or field limitations only once they are diagnosed and managed.

Ask: "Which column is your student living in right now?"

Frame the slide: "Why performance-based measurement holds up."

Walk each point, one sentence each:

• Repeated measurement of the same task documents change more defensibly than a single score.

• Condition-dependent performance is the signal payers and teams act on.

• Occupation-embedded probes carry the transfer argument with them.

• Graded reference list with levels of evidence is published in the PD documentation.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Set up the clip in one sentence, play it, then debrief with "what did you notice?"

Describe what belongs here: Side-by-side comparison illustrating what each source of evidence shows..

Describe what belongs here: Classroom photo showing the occupational demand behind a typical referral..

Land the "so what": Norm-referenced batteries tell you where a student ranks. They rarely tell you which condition to change on Monday.

Explain the mechanism plainly: Performance-based assessment manipulates conditions — distance, duration, size, complexity — so the result names the demand that breaks performance.

Then give them the moves — say each one as something they can do Monday:

• Ask what decision the score will drive before you administer anything.

• Record the condition under which performance changed, not only the score.

• Pair any norm-referenced result with a performance observation in the same report.

Tell them what success looks like: A percentile in the average range beside a student who cannot complete a page — that gap is the finding.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Two-minute case. Read it aloud:

A Grade 3 student scores in the average range on a norm-referenced visual perception battery, yet cannot complete grade-level written work.

Put the question to them: "What did the battery miss, and what do you do next?" Give 60 seconds, no talking.

Model answer (reveal after they commit): The battery sampled brief, untimed, single-item processing. It never sampled sustained near performance under classroom duration and layout. Run a performance-based sample at the real distance and duration, and document completion, place-losing, and time to degradation.

Close with the rule: Average capacity under ideal conditions is compatible with failure under classroom conditions.

Reflection prompt: "Recall a standard score that did not match what you saw in the classroom. What did the battery miss?"

Offer the sentence starter: "The battery score was... but in the classroom I saw... The battery missed..."

Think for one minute, write, then take two shares.

Knowledge check: "What does a norm-referenced perceptual battery not tell you?"

Options:

• How the student compares to same-age peers

• How performance holds up under real task demand and duration

• Whether the score is statistically reliable

• Which subtest was lowest

Correct answer: option 2. Rationale: Batteries sample brief, isolated performance. Occupational breakdown usually shows up in sustained, contextual demand.

Transition: "VPA™ architecture: 15 skills across 5 domains, Fast Screener vs. Mini vs. Full."

Open here. "VPA™ Architecture." 15 skills across 5 domains — Fast Screener, Mini VPA™, and Full VPA™.

Say why this section matters for their caseload, then advance.

Ask the poll: "Given 20 minutes with a new referral, what would you run today?"

Options:

• Fast Screener

• Mini VPA™

• Full VPA™

• I would not know which to pick

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Run the five levels bottom-up.

Name each level, then say which one you assess first and why.

Contrast the two columns: Mini VPA™ (screen) versus Full VPA™ (assess).

Mini VPA™ (screen):

• One probe at each of Levels 1–5

• Flags the domains needing measurement

• Caseload-scale, brief

• Never a stand-alone plan of care

Full VPA™ (assess):

• 15 skills, L1–L5 progression each

• Basal and ceiling rules per skill

• Domain profile and composite

• Drives goals, dosage, referral

Ask: "Which column is your student living in right now?"

Talk over the visual: "Mini VPA™ administration view."

Say the caption in your own words: Say/Do script, level ladder, and the scoring worksheet in one clinician view.

Frame the slide: "Why 15 skills across 5 domains."

Walk each point, one sentence each:

• Each domain samples one level of the framework: Access, Efficiency, Processing, Visual-Motor Integration, Functional Integration.

• Three skills per domain give enough spread to see a shape, not a point.

• Every skill runs its own L1–L5 task ladder, so breakdown is located, not inferred.

• Functional Integration includes both reading and writing — the two referral drivers.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: What you record at the table versus What the software derives.

What you record at the table:

• Item rubric 0–3 for every task you administer: 0 unable, 1 emerging with maximum support, 2 functional with inefficiency, 3 accurate and efficient.

• A rubric of 2 or 3 counts as passing that task; 0 or 1 does not.

• Observation is recorded alongside every rubric score — head movement, refixations, latency, discomfort.

What the software derives:

• Achieved level L1–L5: the highest task level scored 2 or better on that skill.

• VPL 1–5 (Visual Performance Level): achieved level adjusted for rubric quality — VPL 1 (emerging), VPL 2 (developing), VPL 3 (functional), VPL 4 (efficient), VPL 5 (advanced). Always write the number; “functional” is a descriptor of VPL 3, not the name of Domain 5.

• Gap: VPL compared to the expected VPL range for the student’s age band.

Ask: "Which column is your student living in right now?"

Frame the slide: "When to reach for a standardized tool."

Walk each point, one sentence each:

• A single skill is flagged and you need depth for eligibility.

• A payer or district requires a norm-referenced score.

• Team disagreement about whether the finding is real.

• Use adjuncts to deepen a flagged area — not to replace the level profile.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Set up the clip in one sentence, play it, then debrief with "what did you notice?"

Describe what belongs here: Architecture graphic showing domains, skills, and the L1–L5 ladder..

Describe what belongs here: Skill menu view showing the 15 skills grouped by domain..

Land the "so what": Fast Screener, Mini, and Full are three different commitments of time. Choosing the wrong tier costs you a session you will not get back.

Explain the mechanism plainly: Screening routes, Mini characterizes a suspected domain, Full establishes level and profile across all fifteen skills.

Then give them the moves — say each one as something they can do Monday:

• Fast Screener when the question is "does this need looking at?"

• Mini when you suspect a domain and need to confirm before writing a goal.

• Full when you need an achieved level, a domain profile, and a progress baseline.

Tell them what success looks like: Repeating a Mini three times — that is a Full you have already paid for in pieces.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Two-minute case. Read it aloud:

You have 25 minutes with a newly referred Grade 2 student, an IEP meeting in three weeks, and a teacher report of place-losing and slow copying.

Put the question to them: "Which tier do you run today, and what do you schedule?" Give 60 seconds, no talking.

Model answer (reveal after they commit): Run the Mini today, targeted at the suspected efficiency domain, so you have defensible information for the meeting. Schedule the Full before goal-writing if the Mini confirms the domain, and use the Fast Screener for the two other students on the same referral list.

Close with the rule: Match the tier to the decision and the calendar, not to how thorough you feel.

Reflection prompt: "Which of the 15 skills do you currently never assess — and what has that cost you?"

Offer the sentence starter: "I currently do not assess [skill]. This has cost me because..."

Think for one minute, write, then take two shares.

Knowledge check: "When is the Fast Screener the right instrument?"

Options:

• When you need a score for the IEP

• When you need to rule a concern in or out and decide the next step

• When the family requests a full evaluation

• When the student is under 8 years old

Correct answer: option 2. Rationale: The Screener sorts. The Mini and Full measure.

Transition: "Age bands, stimulus selection, and setup: working distance, lighting, materials, positioning."

Open here. "Age Bands, Stimuli, and Setup." Working distance, lighting, materials, and positioning — the fidelity floor.

Say why this section matters for their caseload, then advance.

Ask the poll: "How consistently is your working distance actually measured?"

Options:

• Measured every administration

• Estimated by eye

• Set once at the start of the year

• Not controlled yet

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Frame the slide: "Non-negotiables before the first item."

Walk each point, one sentence each:

• Intermediate tasks at 60 cm, near tasks at 40 cm — measured, not estimated.

• Even, glare-free lighting; stimulus plane perpendicular to the line of sight.

• Seated with feet supported, work surface at elbow height.

• Habitual correction worn; note if the student left glasses at home.

• Age band selected by chronological age: 5–7, 8–11, 12–16, 17+.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Frame the slide: "Why stimuli change with the band."

Walk each point, one sentence each:

• Level content is developmentally scaled — shapes, then letters, then words, then sentences.

• Reading and writing probes track grade-level print and demand.

• Distance-specific cards exist for intermediate and near; do not substitute.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: 5–7 and 8–11 versus 12–16 and 17+.

5–7 and 8–11:

• Shapes and single letters at the lower levels

• Shorter passages, larger print, more frequent breaks

• Writing sample: copying and short generative sentences

• Heavier reliance on demonstration in the Do line

12–16 and 17+:

• Words, sentences, and dense paragraph-level print

• Longer sustained-demand probes for endurance

• Writing sample: paragraph generation under time

• Self-report of symptoms carries more diagnostic weight

Ask: "Which column is your student living in right now?"

Contrast the two columns: What stays the same at L4 / L5 versus What the student actually sees.

What stays the same at L4 / L5:

• Difficulty is set by the level: 18 px print at L4, 12 px at L5; 8 then 10 saccade items per column.

• Sustained-demand timing is set by the level and the band together — 90 s to 2 min at ages 5–7, 5 to 10 min at 12+ and adult.

• Basal and ceiling rules are identical in every band.

What the student actually sees:

• 5–7: pond and field-trip narratives; saccade columns of shapes and CVC words.

• 8–11: harbor and astronomy passages; letter columns with multi-syllable words.

• 12–16: technology and public-health passages; digit/letter columns with academic vocabulary.

• 17+: acquired brain injury and ocular-motor passages; alphanumeric pairs with clinical vocabulary.

Ask: "Which column is your student living in right now?"

Contrast the two columns: Band-adapted (the material changes) versus Level-only (deliberately band-neutral).

Band-adapted (the material changes):

• Saccade columns — symbols and CVC words at 5–7, letters and multi-syllable words at 8–11, digit/letter pairs with academic vocabulary at 12–16, alphanumeric pairs with clinical vocabulary at 17+.

• Reading passages and the read-aloud instruction — separate banked passages, and the expected oral rate anchor moves 45 → 85 → 110 → 130 wpm.

• Writing prompts — name and tracing, then functional words, then sentence stems, then a mock form or memo.

• Visual discrimination trials — shape sets for the youngest band, letter and word sets above it.

• Fixation-under-load: count to 10, count by 2s, or serial 3s backward, by band.

• Functional Integration L1–L5 scripts — reading tier and writing demand are chosen for the band before the block starts.

Level-only (deliberately band-neutral):

• Form constancy, visual closure, and spatial relations — geometric and orientation judgments; the difficulty is the geometry, not the vocabulary.

• Visual memory set size and exposure time — set by level so the same construct is measured across ages.

• Convergence target size and VMI copy figures — scaled by level, identical stimulus across bands.

• Basal, ceiling, rubric (0–3), and achieved-level rules — identical in every band.

Ask: "Which column is your student living in right now?"

Land the "so what": Working distance, lighting, and positioning change scores more than most skill differences you are trying to detect.

Explain the mechanism plainly: If setup drifts between administrations, your progress line measures your setup, not the student.

Then give them the moves — say each one as something they can do Monday:

• Measure and record working distance every administration.

• Set posture and lighting before the first item, not after item three.

• Use the same age-band stimuli and the same materials at reassessment.

Tell them what success looks like: A large change at reassessment with no intervention change — check your setup before you celebrate.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Set up the contrast: "Postural setup changes what you are measuring."

Point at the before panel first. Feet unsupported, trunk collapsed, page about 15 cm from the eyes.

Then the after panel. Feet supported, hips back, page raised toward a slant, working distance near Harmon distance.

Say the rule out loud: Fix posture and distance before you score anything. Otherwise you are documenting the setup, not the student.

Ask: "What did we change — the child, or the demand?"

Two-minute case. Read it aloud:

A student scores markedly better at the 9-week reassessment. You administered the first session at a table with the student standing and the second seated with a slant board.

Put the question to them: "What can you report?" Give 60 seconds, no talking.

Model answer (reveal after they commit): You cannot attribute the change to the intervention. Document the setup difference, re-administer under the original controlled setup, and report the change only when the conditions match. Note the slant-board response separately as a modification finding.

Close with the rule: Progress data is only interpretable when the setup is held constant.

Knowledge check: "A 15-year-old with an intellectual disability reads at a first-grade level and is referred for worksheet navigation. You administer the 12–16 band and she fails Level 4 figure-ground on a text-embedded array. What went wrong?"

Options:

• Nothing — the failure is a valid Level 4 figure-ground finding.

• The text-embedded stimulus measured reading access as much as figure-ground; select down a band and record the substitution and the reason.

• She should have been given the Pre-K Quick Screen instead.

• Figure-ground should be dropped from the protocol for this student.

Correct answer: option 2. Rationale: Band selection defaults to chronological age, but reading or receptive-language access can justify selecting down. Administer the accessible band, record the substitution and why, and interpret against that band. An unrecorded band substitution is the most common cause of uninterpretable VPA™ data — and the Pre-K Quick Screen is for ages 3–4, not for older students with lower reading levels.

Frame the slide: "Eye dominance: Porta and Miles tests."

Walk each point, one sentence each:

• Extended-arm method: patient extends one arm, holds a thumb or wand upright, and aligns it with a distant target using both eyes open.

• Porta test: cover one eye at a time — the dominant eye is the one that keeps the object aligned with the target when the other eye is covered.

• Miles test: patient views the target through a small triangle formed by the hands at arm’s length; closing the dominant eye makes the target appear to jump off-center.

• Record which eye is dominant and whether the result is consistent across trials.

• Note if dominance is unstable or switches between trials — this is itself an observation worth recording, not a diagnosis.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: Cover–uncover versus Alternate cover.

Cover–uncover:

• Student fixates a target; cover one eye, then remove the cover.

• If the uncovered eye moves to re-fixate, that is a sign of a manifest eye turn.

• Note which eye moved and the direction.

Alternate cover:

• Alternate the cover briskly between the eyes.

• Movement as the cover shifts onto an eye suggests a latent deviation.

• Note the direction — in, out, up, down.

Ask: "Which column is your student living in right now?"

Frame the slide: "Below the floor of the VPA™."

Walk each point, one sentence each:

• Ages 3–4 use the Pre-K Quick Screen — refer or offer simple activities.

• Do not force a 5–7 band protocol onto a preschooler; the data will not hold.

• Document what you observed functionally and set a re-check date.

Close with: "If you only take one of these back, take the first one."

Set up the clip in one sentence, play it, then debrief with "what did you notice?"

Describe what belongs here: Two photos or one composite showing both working distances..

Describe what belongs here: Band picker showing 5–7, 8–11, 12–16, 17+..

Reflection prompt: "Name the two client or contextual factors that will drive age band and stimulus selection for your next student."

Offer the sentence starter: "For [student], the age band is driven by... and the stimulus selection is driven by..."

Think for one minute, write, then take two shares.

Knowledge check: "Why is uncontrolled working distance a scoring problem, not just a tidiness problem?"

Options:

• It makes the session run long

• It changes the visual demand, so the score no longer means what the norms mean

• It makes the student uncomfortable

• It affects lighting only

Correct answer: option 2. Rationale: Distance changes angular size and accommodative demand. An unmeasured distance makes the result uninterpretable.

Transition: "Administering the Mini VPA™: the seven probes, scripts, prompting limits, and observation cues."

Open here. "Administering the Mini VPA™." Five probes, verbatim scripts, prompting limits, and observation cues.

Say why this section matters for their caseload, then advance.

Ask the poll: "Which prompting error are you most at risk of during administration?"

Options:

• Repeating the item after a delay

• Adding encouragement that cues the answer

• Allowing extra time past the limit

• Rephrasing the script

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Frame the slide: "Script discipline."

Walk each point, one sentence each:

• Read the Say line verbatim; the Do line defines your hands and the timing.

• One repetition of instructions is permitted; further prompting is recorded, not free.

• Score performance, not effort — note effort separately as an observation.

• Record the observation cues (place loss, head movement, working distance drift).

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Frame the slide: "What triggers a Full VPA™."

Walk each point, one sentence each:

• Any probe failed at or below the expected level for the band.

• Any probe passed only with degraded rate, endurance, or strategy.

• Teacher/caregiver report that conflicts with a passed probe.

• Any red-flag ocular symptom — refer regardless of the screen result.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: Pursuit: look for versus Saccade: look for.

Pursuit: look for:

• Symmetry between the two eyes as they track

• Head movement substituting for eye movement

• Target drift — eyes falling behind or leading the target

• Change in focal distance or working distance during the task

Saccade: look for:

• Accuracy of landing on the target placement

• Undershoot or overshoot of the intended fixation point

• Fatigue — accuracy degrading over repeated trials

• Loss of fixation between jumps

Ask: "Which column is your student living in right now?"

Frame the slide: "Near point of convergence — the penlight probe."

Walk each point, one sentence each:

• This belongs to the Level 2 efficiency probe. You run it here in the Mini, and again inside Domain 2 of the Full.

• Start the penlight or accommodative target at about 18 in, midline, at eye level.

• Move it slowly toward the bridge of the nose while the student holds fixation.

• Record the break — the distance at which the student reports doubling or you see an eye drift out.

• Move back out and record the recovery distance. Run three trials: a break that recedes across trials is the finding.

• Stop for any report of pain; record head movement, squinting, or an outward eye turn.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Contrast the two columns: Levels 1–3 versus Levels 4–5.

Levels 1–3:

• L1 — acuity at the measured distance, correction worn

• L2 — oculomotor efficiency and near endurance

• L3 — a visual processing probe appropriate to the band

• Score the level achieved, not the raw item count

Levels 4–5:

• L4 — visual-motor copy accuracy

• L5 — functional reading and a writing sample

• Record rate, prompts, and place-loss events

• Any degraded pass is still a flag

Ask: "Which column is your student living in right now?"

Frame the slide: "What to watch while they work."

Walk each point, one sentence each:

• Working distance drift and head movement instead of eye movement.

• Place loss, re-reading, and finger tracking that was not there at baseline.

• Squinting, blinking bursts, eye rubbing, or turning away from the page.

• Strategy: does the student narrate a plan or guess and check?

Set up the clip in one sentence, play it, then debrief with "what did you notice?"

Describe what belongs here: Clinician view of a probe script with the level ladder visible..

Describe what belongs here: Positioning photo showing the clinician’s line of sight to the eyes..

Land the "so what": Every extra prompt you add turns an assessment item into a teaching trial, and the score stops meaning what the manual says it means.

Explain the mechanism plainly: The five Mini probes are standardized in wording, demonstration, and prompting limits.

Then give them the moves — say each one as something they can do Monday:

• Read the script; do not paraphrase into encouragement.

• Stay inside the stated prompting limit and record any prompt given.

• Write observation cues as you go — they carry the clinical meaning the score cannot.

Tell them what success looks like: Yourself coaching. If you helped, note it; a scored item with an unrecorded prompt is unusable.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Two-minute case. Read it aloud:

Mid-probe, a student stalls and you say "remember to start at the left." He then completes the item correctly.

Put the question to them: "How do you score and document it?" Give 60 seconds, no talking.

Model answer (reveal after they commit): Score according to the prompting rule for that probe — the item was completed with a prompt beyond the limit, so it does not count as independent. Record the exact cue and the response; that pairing is valuable intervention information even though the item is not credited.

Close with the rule: Never quietly upgrade a prompted response. Document the prompt and use it clinically.

Reflection prompt: "After scoring yourself on the fidelity checklist, which two items will you rehearse before your first real administration?"

Offer the sentence starter: "I will rehearse [item 1] and [item 2] because..."

Think for one minute, write, then take two shares.

Knowledge check: "A student pauses; you say "you can do it, look again at the top." What have you done?"

Options:

• Provided allowable encouragement

• Provided a cue that changes the task and must be recorded as a prompting deviation

• Nothing that affects the score

• Invalidated the entire administration

Correct answer: option 2. Rationale: Directional information is a cue. Record it as a deviation; the item score is no longer comparable to the standard condition.

Transition: "Administering the Full VPA™: level progression, basal and ceiling rules, validity flags."

Ask the poll: "What most often makes you unsure when to stop testing?"

Options:

• Deciding the basal

• Deciding the ceiling

• Knowing when to drop back a level

• Fatigue and behavior confounds

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Frame the slide: "Progression, basal, ceiling."

Walk each point, one sentence each:

• Every skill runs sequentially L1 → L5; no adaptive skipping.

• Basal: the highest level performed cleanly without prompting.

• Ceiling: the level at which performance breaks down and stays broken.

• Record the achieved level per skill — that number, not a raw total, drives the profile.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Frame the slide: "The five validity threats."

Walk each point, one sentence each:

• Setup drift — distance, lighting, or positioning changed mid-session.

• Fatigue or state — illness, hunger, medication timing, time of day.

• Attention and effort inconsistency across comparable items.

Frame the slide: "The 15 skills sit on the five levels."

Walk each point, one sentence each:

• Level 1 · Access — near acuity, intermediate/distance acuity, contrast tolerance. Nothing above this level is interpretable if it fails.

• Level 2 · Efficiency — fixation, pursuits, saccades with near point of convergence and endurance.

• Level 3 · Processing — discrimination and closure, figure-ground, visual memory and spatial relations.

• Level 4 · Visual-motor integration — form reproduction, copy accuracy, timed written output.

• Level 5 · Functional integration — sustained reading, generative writing, classroom-task simulation.

Frame the slide: "Keeping a full battery clean."

Walk each point, one sentence each:

• Order skills so fatigue-sensitive probes are not all at the end.

• Break at fixed points, not when performance dips.

• Re-state the setup after every break; re-measure distance.

• Split across two sessions rather than pushing through fatigue.

Set up the clip in one sentence, play it, then debrief with "what did you notice?"

Describe what belongs here: Runner view showing the level ladder and scoring panel..

Describe what belongs here: Bench setup: cards, worksheets, timer, measured distances..

Land the "so what": Correct basal and ceiling rules keep a student out of twenty items they were always going to fail — and keep your session inside its window.

Explain the mechanism plainly: Level progression is designed to find the boundary of performance, not to sample everything.

Then give them the moves — say each one as something they can do Monday:

• Establish basal before you climb; a false basal invalidates everything above it.

• Stop at the ceiling rule even when you are curious.

• Flag validity threats in the moment — fatigue, attention, correction not worn, setup drift.

Tell them what success looks like: Frustration behavior climbing before the ceiling rule triggers — stop and note the validity flag.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Two-minute case. Read it aloud:

You start at the age-band entry point, the student misses two of the first three items, and you keep going upward hoping he settles.

Put the question to them: "What went wrong and what do you do?" Give 60 seconds, no talking.

Model answer (reveal after they commit): Basal was never established, so nothing above it is interpretable. Drop back to the previous level and work down until the basal rule is met, then re-climb. If time runs out, report only what is valid and schedule completion rather than reporting an unfounded level.

Close with the rule: An achieved level without a basal is a guess with a number attached.

Reflection prompt: "Which of the five validity threats do you see most in your setting, and what will you change to control it?"

Offer the sentence starter: "The validity threat I see most is... I will control it by..."

Think for one minute, write, then take two shares.

Knowledge check: "A student fails the first two items at the entry level. What do you do?"

Options:

• Stop and record the achieved level

• Drop back a level to establish the basal before continuing

• Continue to the ceiling rule anyway

• Repeat the items with prompting

Correct answer: option 2. Rationale: Without an established basal, the achieved level is not defensible. Drop back, establish it, then work up.

Transition: "Scoring and interpretation: achieved level, domain profile, composites, and flag logic."

Open here. "Scoring and Interpretation." Achieved level, domain profile, composites, and flag logic.

Say why this section matters for their caseload, then advance.

Ask the poll: "Which profile shape do you find hardest to interpret?"

Options:

• Flat low

• Bottom-heavy

• Top-heavy

• Spiky and inconsistent

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Frame the slide: "Read the shape before the numbers."

Walk each point, one sentence each:

• Flat low — rule out validity threats and sensory floor before interpreting.

• Bottom-heavy — efficiency and endurance limit everything above; treat the floor first.

• Top-heavy — floors are clean; breakdown sits in integration and functional demand.

• Spiky — isolated skill deficits; confirm with a second probe before goal writing.

Ask the poll: "A scored VPA™ lands on your desk. What is the first thing you look at?"

Options:

• The composite / mean VPL

• The lowest single skill score

• The shape of the five-domain profile

• The validity flags and administration notes

Take a show of hands or the on-screen tally, then name the pattern you see before advancing.

Run the five levels bottom-up.

Spend your time on Level 2 — that is the point of this slide.

Contrast the two columns: Profile A — L1:4 L2:2 L3:5 L4:4 L5:2 versus Profile B — L1:4 L2:4 L3:4 L4:2 L5:2.

Profile A — L1:4 L2:2 L3:5 L4:4 L5:2:

• Mean VPL 3.4 — looks unremarkable in a composite.

• Bottom-heavy: the floor is the limiter and the top is the symptom.

• Entry point: Level 2, inside reading and copy tasks.

• Prognosis: the most treatable pattern in the framework.

Profile B — L1:4 L2:4 L3:4 L4:2 L5:2:

• Mean VPL 3.2 — nearly the same composite.

• Top-heavy: sees it, holds it, interprets it, cannot produce it.

• Entry point: Level 4, plus output-format accommodation.

• Prognosis: remediation plus compensation, weighted to compensation as age rises.

Ask: "Which column is your student living in right now?"

Land the "so what": The domain profile is what you treat. The composite is what you say in the meeting when someone wants one number.

Explain the mechanism plainly: Two students with the same composite can need completely different intervention if their domain profiles differ.

Then give them the moves — say each one as something they can do Monday:

• Read the profile shape first, the composite second.

• Convert the lowest interpretable domain into one goal, not four.

• Report flags plainly; an unflagged invalid profile misleads the whole team.

Tell them what success looks like: A flat profile with a low composite — that pattern often points back to Level 1 or setup, not to a single domain.

Ask: "Who has a student this describes right now?" Take one answer, then move.

Set up the contrast: "Before / after: how the same profile gets reported."

Point at the before panel first. Nothing here tells the team what to change.

Then the after panel. The reader knows the domain, the demand, and the next measurement.

Say the rule out loud: One number opens the conversation. The profile is what earns the service and directs the intervention.

Ask: "What did we change — the child, or the demand?"

Two-minute case. Read it aloud:

Two Grade 4 students have nearly identical composites. One has a flat profile; the other has a sharply low efficiency domain with the rest at band expectation.

Put the question to them: "Do they get the same plan?" Give 60 seconds, no talking.

Model answer (reveal after they commit): No. The sharply low efficiency profile gets a targeted near-endurance and page-navigation plan with a specific dosage. The flat profile prompts you to re-check Level 1 factors, validity flags, and setup before writing any domain-specific goal, because a uniformly depressed profile is often a global or setup finding.

Close with the rule: Treat the shape of the profile, not the height of the composite.

Reflection prompt: "Take one student you have assessed. Write the single sentence you would say when the team asks "so what does the vision testing mean?" — it must name the occupation, the limiting visual performance factor in criterion language, and the observable impact."

Cues:

• Would a general education teacher be able to picture it?

• Does any word in it imply a diagnosis you did not make?

• Could a parent repeat it to an eye doctor accurately?

Offer the sentence starter: "During ____________, ____________ limits performance; the observable result is ____________."

Think for one minute, write, then take two shares.

Talk through this branch step in Module 6.

Talk through this branch step in Module 6.

Knowledge check: "Which statement is both criterion-referenced and occupation-linked?"

Options:

• Student demonstrates below-average visual motor integration skills.

• Student has convergence insufficiency affecting reading.

• During sustained silent reading, the student performs below the Level 3 near-point efficiency criterion for the 8–11 band; after about four minutes he loses the line and rereads, roughly doubling assignment completion time.

• Visual perceptual deficits are impacting academics.

Correct answer: option 3. Rationale: Option 1 uses normative language for a criterion-referenced instrument. Option 2 names a binocular vision diagnosis, which is outside OT scope. Option 4 names neither a criterion nor an occupation. Option 3 carries occupation + criterion-referenced factor + observable impact, and it writes its own goal.

Contrast the two columns: Per skill versus Per domain.

Per skill:

• Each task is rubric-scored 0–3; a 2 or 3 passes that task

• Achieved level = the highest task level scored 2 or better

• Reported as VPL 1–5, the achieved level adjusted for rubric quality

• Record prompts, rate, and error type alongside the score

• Flag any validity threat at the item where it occurred

Per domain:

• Average achieved level across the domain’s skills

• Compare against the expected level for the age band

• Look at spread within the domain before averaging in your head

• Composite is a summary, never the interpretation

Ask: "Which column is your student living in right now?"

Frame the slide: "When a standardized chart adds value."

Walk each point, one sentence each:

• Acuity and contrast: Colenbrander, MNRead, Lea Low Contrast, and mixed-contrast charts add graded depth to a flagged acuity level.

• Field screening: confrontation testing, tangent screen, and Damato campimetry can characterize a flagged visual field concern.

• DEM (Developmental Eye Movement test) can add standardized depth to an oculomotor efficiency flag.

• Reach for these tools when the VPA™ flags a Level 1 or Level 2 concern and eligibility or team consensus calls for a norm-referenced number.

• These are adjuncts that deepen a flagged finding — they do not replace the VPA™ profile as the primary measure.

Point at the figure while you talk — name the parts before the labels.

Close with: "If you only take one of these back, take the first one."

Frame the slide: "Turning the profile into a plan of care."

Walk each point, one sentence each:

• Start at the lowest unstable level; stabilize before climbing.

• Write goals at Level 5 — the occupation — even when treating a floor.

• Dose it with FITT-P: Frequency, Intensity, Time, Type, Progression — the same dosage frame used in rehabilitation exercise prescription, applied to visual demand. Module 8 works a full example.

• Name the re-probe date and the criterion that advances the student before the first session.

• Pair every remedial target with an access change the teacher can keep.

Reflection prompt: "Take a profile in front of you. Name the domain and level that most likely account for the breakdown, and write the rationale in one sentence."

Offer the sentence starter: "The domain is... at level... The rationale is..."

Think for one minute, write, then take two shares.

Knowledge check: "A bottom-heavy profile with intact upper-level scores most often means what?"

Options:

• The upper-level scores are invalid

• A foundational efficiency or access problem is being compensated for at cost

• The student was inattentive

• The framework does not apply to this student

Correct answer: option 2. Rationale: Compensation is expensive. The upper-level performance is real but unlikely to hold under sustained classroom demand.

Read the scenario aloud, slowly:

Intake: passed a kindergarten vision screening, no eye examination since, no glasses, homework is "a battle." Band 5–7. Findings — L1: near acuity at criterion both eyes; intermediate acuity at 60 cm one line below criterion with a one-line difference between the eyes; Maya leans toward the card. L2: fixation and pursuits at criterion; NPC break 9 cm, recovery 13 cm, stable across three trials. L3: at criterion through Level 4. L4: form copying reaches Level 3, orientation errors on diagonal intersections. L5: reading at criterion for grade; writing sample shows b/d reversals and an inconsistent baseline.

Then put these questions to the room:

• The referral says "reversals." Does the data support a processing explanation?

• Which single finding carries the most clinical weight?

• What is the disposition?

Answer to Q1: No. Discrimination and form constancy are at criterion through Level 4 — that is exactly the skill set that would be weak if the reversals were perceptual. At age 7 with intact discrimination, b/d reversals sit inside ordinary developmental variation.

Answer to Q2: The intermediate acuity finding: one line below criterion at 60 cm, a one-line interocular difference, and a compensatory lean. That is Level 1, in a child who has never had a comprehensive eye examination — and 60 cm is exactly the distance the board-copying complaint lives at.

Answer to Q3: Refer for a comprehensive eye examination. Change the environment now — seating, contrast, and copy-from-desk instead of copy-from-board. Re-assess Levels 3 through 5 after the ocular question is settled, because a Level 1 finding makes everything above it provisional.

Read the scenario aloud, slowly:

Intake: glasses worn consistently, eye examination 8 months ago, headaches during silent reading, avoids reading homework. Band 8–11. Findings — L1: at criterion both distances. L2: fixation at criterion; saccades reach Level 3, with head movement on every horizontal shift at Levels 4 and 5 and two refixations per line; NPC break recedes across trials from 8 cm to 14 cm. L3: at criterion through Level 5. L4: at criterion through Level 4. L5: reading rate at criterion for the first two minutes then decays; line loss begins around four minutes; writing volume falls off in the final third.

Then put these questions to the room:

• What in this profile separates an efficiency finding from a processing finding?

• Which single observation is the strongest in the protocol?

• What is the disposition — and what does the teacher need to hear?

Answer to Q1: The time course. Everything is fine at the start and degrades over minutes — that is fatigue-sensitive machinery. A processing deficit is impaired from the very first item, not the fourth minute. Levels 3 and 4 are at criterion, which rules processing out directly.

Answer to Q2: The receding NPC across three trials — 8 cm to 14 cm. It corroborates both the reading decay and the headaches, and no other finding accounts for all three as plausibly.

Answer to Q3: Both paths at once. Refer for an eye examination specifically addressing near-point function — binocular diagnosis and any lens or optometric therapy decision is not ours — and start OT intervention on near-point endurance and saccadic accuracy inside real reading. Tell the teacher: "He can do it when he tries" is exactly what this finding looks like from the back of the room. The ability is real; the endurance is not.

Read the scenario aloud, slowly:

Intake: glasses, current examination, no discomfort reported, strong verbal performance, OT in elementary school discharged in grade 4. Band 12–16. Findings — L1 and L2 at criterion throughout. L3 at criterion through Level 5. L4: grid-pattern reproduction reaches Level 2; proportion and spatial organization break down as grid complexity increases; he rechecks the model repeatedly. L5: reading at criterion; writing sample shows adequate content, poor organization on the line, slow effortful production, visible frustration.

Then put these questions to the room:

• Levels 1, 2, and 3 are clean. What does that rule out?

• What does the repeated model-rechecking tell you?

• What does his age change about the plan?

Answer to Q1: Access, efficiency, and perceptual judgment. He sees it, holds it, and interprets it accurately — and still cannot produce a matching output. That isolates the limiter at Level 4.

Answer to Q2: It is the behavioral signature of intact perception paired with unreliable motor reproduction. He keeps going back to the model because his output does not match what he correctly perceives.

Answer to Q3: At 15, with a long-standing production problem and intact perception, remediation alone is not defensible. The plan needs an occupation-level compensation conversation — keyboarding, scribing, output-format accommodation — alongside any graded practice. And the refusal is not a separate behavior problem; it is a rational response to the finding, so it belongs in the occupational performance statement.
