Comprehensive Assessment
The Comprehensive Dyslexia Assessment at Read901 provides a full, research-based evaluation of your child’s reading and language skills using the Test of Dyslexia (TOD)—a nationally recognized and evidence-aligned assessment developed to identify the characteristics of dyslexia.
Comprehensive Dyslexia Assessment
This in-depth evaluation goes far beyond the pre-screener. It helps you understand why your child is struggling, how dyslexia may be affecting their learning, and what supports or interventions will make the biggest difference.
What the Assessment Includes:
-
Administration of the full TOD battery, covering all areas of reading development:
-
Phonological processing and sound awareness
-
Word reading accuracy and decoding
-
Reading fluency and rate
-
Spelling and written expression
-
Listening comprehension and vocabulary
-
Rapid naming and working memory
-
-
Parent intake interview and review of educational history to ensure all relevant factors are considered.
-
Professional scoring and interpretation by a Certified Academic Language Therapist (CALT).
-
Integration of findings into a clear, easy-to-understand report with actionable next steps.
What You’ll Receive:
-
A comprehensive written report explaining your child’s performance in each skill area.
-
A diagnostic summary indicating whether your child has the profile of dyslexia.
-
Personalized recommendations for school accommodations, classroom supports, and evidence-based intervention programs such as Take Flight (Orton-Gillingham based).
-
A follow-up consultation to review results and discuss next steps in detail.
Who Should Consider a Comprehensive Assessment:
-
Students with ongoing reading, spelling, or fluency difficulties despite classroom support.
-
Children previously identified as “struggling readers” who have not received a formal dyslexia diagnosis.
-
Parents or educators seeking a complete understanding of a child’s reading profile for planning intervention or school supports.
Time Commitment:
-
Testing is typically completed in one or two sessions, depending on whether further testing is needed.
-
Results and the full report are provided within one week, followed by a one-on-one review meeting.
