Constructional Dyspraxia
The 90 Minute Dysgraphia Evaluation
Spacing between words and letters
Bunching words to one side of page
Sentences which trail up or down
Micrographia vs. Macrographia
Print quality
Grip pressure
Fatigue
3
Working Memory
The 90 Minute Dysgraphia Evaluation
• Skills performed in isolation vs. context often
dictate role of executive component in allocating
attention.
• Phonological information tends to be stored in a
sequential manner.
• Students who misjudge margins, have difficulty
previewing how large to write to fit the parameters,
and have unusual spacing may have limited visual
sketchpad.
• Role of anxiety and emotional factors.
• Frequent erasures.
4
Executive Functioning
The 90 Minute Dysgraphia Evaluation
(Semantic/Syntactic Dysgraphia)
Initiating
Sustaining
Inhibiting
Shifting
Organizing
Planning
Self-Monitoring
5
Writing and Spelling Skills
The 90 Minute Dysgraphia Evaluation
• Examine from both a quantitative as well as
qualitative perspective.
• Concentrate on pace, fatigue, effort, and
motivation to yield more specific IEP goals.
• Error analysis of spelling and motoric output
can be helpful.
6
Phonological Awareness Skills
The 90 Minute Dysgraphia Evaluation
(Phonological Dysgraphia)
• Single best predictor of reading and writing
skills in kindergarten and 1st grade.
(Lyon,1996)
• Deficits often result in dysphonetic spelling.

9-12
Skill Mastery
Recite nursery rhymes
Detect rhyming words
Count phonemes in words
Sound-symbol associations
Manipulation of phonemes
Spell non-words
Rapid recognition of sound
patterns.

Retrieval Fluency
The 90 Minute Dysgraphia Evaluation
• Naming speed and fluency better predictor
of literacy deficits than phonological
awareness. (Wolf, 1999)
• Tied in to verbal flexibility.
• Role of anxiety and hippocampal
functioning.
9
Family History
The 90 Minute Dysgraphia Evaluation
• Limited data in the literature.
• Child with learning disabled parent has
eightfold increase in risk of being LD.
(Pennington, 1995)
• Colorado twin study revealed 70%
concordance rate among identical twins and
48% among fraternal twins.
• Research centered around chromosome 6
and 15.
