Reading the profile

Which profile shape do you find hardest to interpret?

Say this

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

Options:

• Flat low

My notes

6.4 — Read the shape before the numbers

Teaching slide

Profile shape

Read the shape before the numbers

  • 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.

Flat low

L0L1L2L3L4

Global limiter or validity threat — check conditions first.

Bottom-heavy

L0L1L2L3L4

Efficiency floor unstable; perception intact. Grade near-point demand.

Top-heavy

L0L1L2L3L4

Floors stable; processing and integration limit output.

Notched

L0L1L2L3L4

Single-level deficit — the cleanest intervention target.

Read shape before you read any single score. Shape names the limiter; the limiter names the plan.

Walk each point, one sentence each:

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

6.5 — What the report may and may not say

Teaching slide

Interpretation discipline

What the report may and may not say

  • Report observed performance, conditions, and occupational impact.
  • Do not name or imply a binocular vision diagnosis.
  • Every recommendation must trace to a recorded score or observation.
  1. 1Set conditions: lighting, distance, seating, materials
  2. 2Screen Level 0 red flags — stop and refer if present
  3. 3Establish basal at the age-entry item
  4. 4Administer to ceiling, scoring against the criterion
  5. 5Log validity observations as they happen
  6. 6Compute level profile and composite
  7. 7Name the limiter and the disposition
The fidelity sequence. Steps are not optional or reorderable — deviations are documented, not absorbed silently into the score.

6.7 — Devon, age 11 — read this profile bottom-up

Five-Level Framework

Worked profile

Devon, age 11 — read this profile bottom-up

1

Visual Acuity & Sensory Foundation

L4 — acuity and contrast at criterion at 60 cm and 40 cm. Floor stable, so everything above is interpretable.

2

Visual Efficiency

L2 — saccades reach L3 with head movement and two refixations per line; NPC recedes 8 → 14 cm across trials. Below the 8–11 expectation. Lowest unstable level.

3

Visual Processing

L5 — discrimination, closure, form constancy, memory all at criterion. Perception is not the limiter.

4

Visual-Motor Integration

L4 — copy and grid reproduction at criterion. Production is not the limiter.

5

Functional Integration

L2 — reading at criterion for two minutes, then decays; line loss at ~4 minutes; writing volume falls off in the final third.

6.8 — Two profiles that both average VPL 3

Comparison

Same numbers, different story

Two profiles that both average VPL 3

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.

6.9 — So what? The profile drives the plan, the composite drives the conversation

So what?

So what?

So what? The profile drives the plan, the composite drives the conversation

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

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

What you do with it

  • 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.

Watch for

A flat profile with a low composite — that pattern often points back to Level 1 or setup, not to a single domain.

The VPA™: Assessment & Clinical Reasoning
9 / 23

Say this

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:

My notes

6.10 — Before / after: how the same profile gets reported

Before / after

Reporting

Before / after: how the same profile gets reported

Before — number only

Nothing here tells the team what to change.

  • • "VPA composite is below expectation for age band."
  • • "Recommend continued OT for visual skills."

After — profile to plan

The reader knows the domain, the demand, and the next measurement.

  • • "Efficiency domain is the lowest interpretable domain; processing and visual-motor are within band expectation."
  • • "Goal targets sustained near page navigation at 40 cm; reassessed on the 9-week cycle under the same setup."

One number opens the conversation. The profile is what earns the service and directs the intervention.

The VPA™: Assessment & Clinical Reasoning
10 / 23

Say this

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.

6.11 — Two-minute case: same composite, different plan

Mini case

Two-minute case

Two-minute case: same composite, different plan

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.

Do they get the same plan?

11 / 23

Say this

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.

The sentence that has to survive the meeting

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.

Scenario 1 — Marcus, age 9: which rule applies?

Marcus is in your 8–11 band. He wore his glasses for the whole session. Partway through the Level 2 saccade columns he began rubbing his eyes and asked to stop; you gave a two-minute break and finished the section. Nothing else was flagged during administration.

Scoring mechanics

From item to profile

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

6.17 — When a standardized chart adds value

Teaching slide

Adjuncts

When a standardized chart adds value

  • 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.

6.18 — Turning the profile into a plan of care

Teaching slide

From data to plan

Turning the profile into a plan of care

  • 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.
