Introduction
Dyslexia is a lifelong difference in how the brain processes language. Standardized tests exist to diagnose dyslexia and describe a learner's specific strengths and challenges. These tests do not fix or cure dyslexia; they only identify it so the right supports can be provided.
Common Dyslexia Tests
Below are widely used tests. Each is a diagnostic tool — it helps build a profile. None of them "fix" dyslexia.
| Test Name | What it measures | Purpose / Note |
|---|---|---|
| DST — Dyslexia Screening Test | Rapid checks of reading, spelling, processing | Flags learners at risk. Does not fix dyslexia. |
| CTOPP — Comprehensive Test of Phonological Processing | Phonological awareness, memory, rapid naming | Explains sound–letter processing difficulties. |
| WRAT — Wide Range Achievement Test | Reading, spelling, arithmetic | Quick academic check; part of wider assessment. |
| WIAT — Wechsler Individual Achievement Test | Reading, writing, oral language, math | Full achievement profile. |
| Woodcock–Johnson | Reading, fluency, comprehension, language | Detailed strengths & weaknesses. |
| GORT — Gray Oral Reading Test | Reading fluency and comprehension | Useful for older learners. |
| PhAB — Phonological Assessment Battery | Sound manipulation, rhyming, memory | Common in the UK. |
