How it works
The TOD starts with a brief screener (TOD-S) to determine an individual’s Dyslexia Risk Index (DRI) and need for further assessment.
Use the TOD-Early (Grades K–2; 5 years, 0 months–9 years, 3 months) to obtain an Early Dyslexia Diagnostic Index or the TOD-Comprehensive (Grade 1 through adulthood; 6 years, 0 months–89 years, 11 months) to obtain a Dyslexia Diagnostic Index (DDI). Use the information from those Indexes, additional TOD diagnostic tests, and the parent, teacher, and self-report rating scales to determine if an individual has dyslexia.
Dyslexia Interventions and Recommendations: A Companion Guide to the Tests of Dyslexia (TOD) provides the ability to use data from TOD-Screener, TOD-Early, and TOD-Comprehensive to adjust classroom instruction or design a tailored intervention plan.
Assessment areas covered:
- Reading Fluency
- Phonics Knowledge
- Decoding Efficiency
- Basic Reading Skills
- Sight Word Acquisition
- Phonological Awareness
- Orthographic Processing
- Auditory Working Memory
- Rapid Automatized Naming
- Reading Comprehension Efficiency
- Visual Verbal Paired Associate Learning
Benefits of the Tests of Dyslexia (TOD™):
- The first Comprehensive Dyslexia Assessment to include interventions tied to the assessment data.
- Suitable for all ages, the TOD offers age and grade-based tests, indexes, and composite scores.
- TOD-Early (Grades K–2; 5 years, 0 months–9 years, 3 months) and TOD-Comprehensive (Grade 1 through adulthood; 6 years, 0 months–89 years, 11 months)
- The screener provides a Dyslexia Risk Index score in 10-15 minutes
- This brief assessment can be given individually or in a group format by teachers or other professionals.
- Includes a detailed and evidence-based Dyslexia Interventions and Recommendations Companion Guide
- The assessment includes Co-Normed Rating Scales.
- Allows for the identification and targeting of an individual's difficulties in acquiring literacy skills.
- Includes tests of reasoning for comparison with reading and spelling
- Allows for universal application regardless of district Specific Learning Disability (SLD) model.
- Stand-alone tests allow for an individually tailored evaluation
