Testing for Dyslexia

Diagnostic Learning Services offers comprehensive evaluations that can diagnose dyslexia.

Dyslexia is a reading disorder that causes difficulties with understanding how sounds and letters come together to make a word. This often causes struggles with accurate and/or fluent word recognition, sounding out of unfamiliar words, reading fluency, and spelling. Dyslexia is NOT letter and number reversals, writing or reading backwards, or the words moving on the page.

With dyslexia, a person has received adequate instruction but has significant difficulties in reading, writing, and spelling. Reading difficulties experienced by an individual with dyslexia are unexpected in relation to their other abilities.
