Dysgraphia Evaluation Checklist: Which Tests to Request and What Scores Mean

The school evaluation came back with a stack of test names, percentile scores, and standard scores. Nobody explained what any of it means for your child's classroom accommodations. And somehow, despite all those numbers, the school says everything looks "fine."

A thorough dysgraphia evaluation needs specific tests. If the school skipped them, you have the right to push back.

Tests Used in a Dysgraphia Evaluation

Dysgraphia sits at the intersection of motor control, spelling, and written composition. A complete evaluation needs to cover all three domains — plus the processing areas that drive them.

Written expression and spelling:

• WIAT-4 (Wechsler Individual Achievement Test): Alphabet Writing Fluency, Sentence Writing Fluency, Essay Composition, Spelling, and the Orthographic Processing Composite. The Alphabet Writing Fluency subtest alone differentiates dysgraphia with a moderate effect size of .70.
• WJ IV Tests of Achievement: Spelling, Writing Samples, and Sentence Writing Fluency. The Writing Samples subtest evaluates composition quality independent of handwriting legibility — critical for separating motor problems from language problems.
• TOWL-4 (Test of Written Language): Vocabulary, Spelling, Punctuation, Logical Sentences, and Story Composition. Provides both contrived writing and spontaneous narrative analysis.

Handwriting speed and motor control:

• DASH or DASH-2 (Detailed Assessment of Speed of Handwriting): Measures handwriting speed in words per minute under different conditions — free writing, copying, and dictation. Essential for documenting motor fatigue.
• Beery VMI (Beery-Buktenica Developmental Test of Visual-Motor Integration): Tests the ability to integrate visual information with motor execution. The supplemental subtests separate visual perception deficits from motor coordination deficits.
• BOT-2 (Bruininks-Oseretsky Test of Motor Proficiency): Comprehensive fine-motor assessment including precision, integration, and manual control.

Cognitive processing:

• WISC-V Processing Speed Index: Slow processing speed combined with written expression deficits supports the pattern-of-strengths-and-weaknesses eligibility model.
• Working memory subtests: Document the cognitive bottleneck that makes writing so exhausting.

What a Low Beery VMI Score Actually Means

Parents often hear "low VMI" without understanding why it matters. The Beery VMI measures visual-motor integration — the ability to coordinate what the eyes see with what the hand does. It has three parts:

The main VMI subtest asks the child to copy geometric forms of increasing complexity. A low score here means the child struggles to translate visual information into motor output — the exact skill handwriting requires.

The Visual Perception supplemental subtest isolates whether the child can perceive the forms correctly without drawing them. The Motor Coordination supplemental subtest isolates motor control without the visual matching component.

Here's why the pattern matters: if VMI is low but Visual Perception is average, the pattern may point to a motor-execution concern and support a request for OT assessment. It does not diagnose dysgraphia on its own.

A Beery VMI standard score below 85 (about the 16th percentile) is one data point, not an IDEA eligibility cutoff. The team must apply state criteria and determine whether the student meets IDEA's disability and special-education-need requirements.

What to Do When the Evaluation Is Incomplete

School evaluations frequently test reading and general intelligence but skip written expression, handwriting speed, and OT motor assessments. That evaluation may be incomplete if it omitted an area related to a suspected disability — and you can ask the team to address the gap.

Under 34 CFR §300.304(c)(4), schools must assess a child in all areas related to the suspected disability. If written expression or motor abilities are suspected and were not assessed, ask the team to explain how the evaluation covered those areas; the regulation does not require a separate OT assessment in every case.

Your options:

Request additional testing. Put it in writing: "I am requesting that the evaluation be expanded to include assessment of written expression (WIAT-4 or equivalent), handwriting speed (DASH), visual-motor integration (Beery VMI), and an occupational therapy evaluation, per 34 CFR §300.304(c)(4)."

Request an Independent Educational Evaluation (IEE) at public expense. Under 34 CFR §300.502, if you disagree with the school's evaluation, you can request an IEE. The district must, without unnecessary delay, either fund it subject to its criteria or file a due process complaint to defend its evaluation; if the district prevails, the IEE is not at public expense.

Translating Clinical Scores to IEP Goals

Private evaluations from psychologists or OTs document deficits using standardized scores. School teams need those scores translated into educational impact and measurable goals.

The translation works like this: a Beery VMI score at the 5th percentile means the child's visual-motor integration is significantly below peers. In the classroom, that translates to illegible handwriting, slow written output, and physical fatigue — all of which adversely affect educational performance.

That clinical finding should map to specific IEP accommodations: keyboarding for all written assignments, speech-to-text for extended responses, and reduced written output requirements. It should also trigger measurable goals — increasing typing speed to a functional threshold, improving written composition length with assistive technology, or building handwriting legibility for brief tasks like name-writing and form-filling.

The Dysgraphia Support & Writing Accommodation Kit includes a clinical-to-IEP translation matrix that maps every major evaluation score directly to enforceable accommodations and measurable goals. If you're staring at a stack of test results and wondering what they mean for your child's classroom, that's the bridge.
