All three questions must be addressed in an evaluation where dysgraphia is suspected.
• Illegible and/or inefficient handwriting with variably shaped and poorly formed letters
• Difficulty with unedited written spelling
• Low volume of written output and problems with other aspects of written expression
Do these difficulties typically result from a deficit in graphomotor function (hand movements used for writing) and/or storing and retrieving orthographic codes (letter forms)?
Are these difficulties unexpected for the student's age in relation to the student's other abilities and the provision of effective classroom instruction?

The Handbook specifically names illegible AND/OR inefficient handwriting. This is clinically important.
A student can produce somewhat readable letters but still meet dysgraphia criteria if:
- Output is effortful and slow — not automatic
- Alphabet writing fluency is significantly below age expectations
- The student fatigues quickly during writing tasks
- Written output volume is far below what the student can produce orally

What it is: A deficit in the motor planning, execution, and coordination required to physically produce letters on a page. Graphomotor skills are a specialized subset of fine motor skills requiring fine muscle control, visual perception, sensory feedback, and motor planning.
Observable indicators:
- Poor pencil grip (thumb wrap, fisted grip)
- Poor adherence to baseline/slant
- Inconsistent letter sizing
- Ascending/descending letters not adhering to line
- Poor margins
- Inconsistent spacing between words
- Slow, labored, effortful production
- Unusual posture or paper placement while writing

What it is: A deficit in storing and retrieving letter forms and letter sequences from long-term memory. The student knows what a word sounds like but cannot reliably retrieve how to form or spell it.
Observable indicators:
- Same letter formed inconsistently across a single writing sample
- Difficulty retrieving letter forms spontaneously ("I want to write 'y' but I can't remember what it looks like")
- Orthographic spelling errors — correct phonology but wrong letter sequences or whole-word forms
- Difficulty with sight word spelling for common, frequently encountered words
- Letter reversals or transpositions persisting beyond early grades

Yes — graphomotor and orthographic deficits frequently co-occur. A student may have poor motor execution and poor letter-form retrieval simultaneously. The distinction still matters because it has different instructional implications: graphomotor intervention focuses on motor patterning and automatization (OT-targeted handwriting programs), while orthographic intervention focuses on building stable mental representations of letter forms and word spellings (structured literacy with explicit orthographic mapping).
Per the Texas Dyslexia Handbook (p. 57), schools shall recommend evaluation for dysgraphia when a student demonstrates either of the following:

The Handbook (p. 60) specifies three evaluation domain columns. The MDT evaluation report must address each column.
Academic Skills
- Letter formation / handwriting
- Word/sentence dictation (timed and untimed)
- Copying of text
- Written expression
- Spelling
- Writing fluency (accuracy and rate)
Cognitive Processes
- Memory for letter or symbol sequences (orthographic processing)
Possible Additional Areas
- Phonological awareness
- Phonological memory
- Working memory
- Letter retrieval
- Letter matching

The Texas Dyslexia Handbook (pp. 55–56) explicitly defines what dysgraphia is not. These exclusions matter for eligibility determinations where co-occurring conditions could explain handwriting difficulties through a different mechanism. Dysgraphia is not:

Graphomotor/Handwriting:
Orthographic Processing:
Written Expression / Composition:
Alphabet Writing Fluency (informal): Ask student to write the alphabet in 1 minute. Count letters written. Below-average rate for age is a strong indicator of graphomotor inefficiency. Conduct dynamic assessment — prompt student to continue after time to assess what they know vs. what they can produce under speed demands.
Copy vs. Dictation Comparison: Compare quality of copied sentence vs. dictated sentence. Note whether legibility, spacing, or formation improves with a model present.
Writing Sample Analysis: Collect samples across conditions — structured prompt, free write, preferred topic, timed vs. untimed. Analyze for volume, legibility, spelling error type, and organizational quality.
Examiner Writing Observation Form: Document grip, posture, pencil pressure, paper placement, erasure patterns, letter formation, spacing, size consistency, baseline adherence, and fatigue indicators.
ESC Region 11 Dysgraphia Examiner's Observation Form available via Aimee Seaberry ([email protected])
Analyze unedited spelling errors from writing samples and formal tasks. Identify the primary error type to differentiate underlying mechanism:
- Orthographic errors — Correct phonology, wrong letter sequences or whole-word forms. Points to orthographic storage/retrieval deficit.
- Phonological errors — Attempt does not preserve phonological structure. Points to phonological processing deficit (dyslexia profile).
- Orthographic letter formation errors — Correct spelling attempt, letters illegible or formed incorrectly. Points to graphomotor deficit.
- Morphological errors — Difficulty with prefixes, suffixes, base words. Points to language-based or DLD profile.

When transcription skills are not automatic, every act of forming a letter or retrieving a spelling requires conscious cognitive effort. This places increased demand on working memory and executive functioning, producing a predictable cascade:
- Reduced writing fluency — output is slow and effortful
- Difficulty sustaining output — student fatigues quickly; writing quality degrades over time
- Limited organization and idea development — cognitive resources consumed by transcription leave nothing for planning, organizing, and elaborating ideas
- Apparent WM/attention weakness — secondary to transcription overload, not necessarily a primary deficit
Source: Seaberry, ESC Region 11 (2025); Wolf & Berninger (2018)
Automaticity of basic transcription skills must be intact before executive functions can direct energy to composition. Based on Wolf & Berninger (2018):
Scribbles showing directionality; imitating writing movements
Forming recognizable letters; letter-sound connections emerging
Integrating spelling, sentence structure, and composition; transcription becoming more fluent
Legible letters produced automatically; improved fluency frees working memory for written composition
Writing is sufficiently automatic and organized to be used as a tool for learning and influencing others
Individual writing style develops; students who find writing too difficult may never reach this stage

A large study of 1,034 referred children (ages 6–16) found that approximately 56–61% of students with ADHD also met criteria for dysgraphia or showed graphomotor weaknesses, with graphomotor weaknesses relative to IQ observed in over 90% of this population. Co-occurrence is the norm, not the exception.
Despite this overlap, the mechanisms are distinct and both may independently contribute to educational need:
| Dimension | Dysgraphia | OHI — ADHD (writing impact) |
|---|---|---|
| Primary mechanism | Graphomotor deficit and/or orthographic processing deficit — writing-specific learning | Attention, executive self-regulation, working memory — access and regulation |
| Writing across conditions | Consistently weak regardless of interest, support level, or environmental structure | Variable — improves meaningfully with interest, structure, verbal rehearsal, movement breaks |
| Copy vs. dictation | Copy does not improve (graphomotor) or inconsistent letter forms (orthographic) | Copy typically improves handwriting quality |
| Response to OT/handwriting intervention | Progress is slow and requires intensive, explicit handwriting instruction targeting motor patterns | May respond more readily once attention/regulation is supported |
| Cognitive testing presentation | Deficits evident even in structured 1:1 testing (orthographic fluency, alphabet fluency) | Deficits often do not appear on cognitive testing due to structured testing environment |
| Dual eligibility appropriate? | Yes — when both conditions independently contribute to educational need. Document each disability's independent contribution to writing difficulties. Both SLD-Written Expression (dysgraphia) + OHI-ADHD may be appropriate. | |

Texas Policy — Dysgraphia & SLD-Written Expression
Dysgraphia can be identified within the SLD-Written Expression category under Texas TAC §89.1040, or can serve as the sole basis for SLD eligibility — a student does not need co-occurring dyslexia or another SLD area to qualify. Students are reported under the SLD eligibility category, but dysgraphia alone in the Written Expression area is sufficient to establish that eligibility. The purpose of naming dysgraphia specifically is to describe the pattern of need, guide intervention decisions (OT vs. structured literacy vs. both), and ensure the ARD committee understands what is and is not working.
HB 3928 (88th Leg., 2023) clarified that dyslexia — and by reasonable extension, dysgraphia — can be listed on its own as the area of SLD identified, without requiring a broader SLD label across multiple achievement areas. This is further supported by the OSERS Dear Colleague Letter (October 23, 2015), which clarified that nothing in IDEA prohibits the use of the terms dyslexia, dysgraphia, and dyscalculia in evaluation reports, eligibility determinations, and IEP documents.
The Texas Dyslexia Handbook (2024) addresses dysgraphia explicitly at p. 61–64. Identification requires evidence of graphomotor and/or orthographic processing deficits that are unexpected for age given adequate instruction — the same "unexpected" standard that applies to dyslexia identification.
OT involvement: TEA SLD guidance (2025) notes that an occupational therapist should be included on the MDT when graphomotor deficits are suspected. OT assessment (Beery VMI, motor coordination measures) provides important convergent data and informs service recommendations.
