Understanding this evaluation

A dyslexia evaluation identifies the nature and severity of reading difficulty and distinguishes it from gaps in instruction, attention concerns, language differences, or broader learning needs.

Questions families ask

How early can dyslexia be identified?+

Risk can be recognized before a child is far behind. A qualified evaluator considers age, instruction, response to intervention, and the reliability of available measures.

Does a vision problem cause dyslexia?+

Dyslexia is language-based, not caused by seeing letters backward or by routine vision problems. Vision care remains important, but vision therapy is not a treatment for dyslexia.

What instruction helps?+

Many children benefit from explicit, systematic teaching of phonemic awareness, phonics, decoding, spelling, fluency, and language, adjusted to their needs.
