Understanding Dyslexia: Signs to Watch for by Age

National Center on Improving Literacy

Dyslexia can manifest differently depending on a child’s age and stage of reading development. Early identification is critical to provide effective support and intervention.

Preschool Years
Age: 3-5

In the preschool years, many children begin developing an awareness of sounds in language and the concept of print. Typical readers at this age often:

  • Enjoy playing with sounds and rhymes

  • Recognize some letters, especially those in their name

  • Begin to understand that printed words carry meaning

Children at risk for dyslexia, on the other hand, may:

  • Struggle to learn common nursery rhymes

  • Not recognize rhyming patterns

  • Have trouble remembering letter names

  • Continue to use “baby talk” well past toddlerhood

These early difficulties can point to challenges with phonological awareness—an early warning sign of reading difficulties

Kindergarten to 1st Grade
Age: 5-7

As children move into kindergarten and first grade, they typically learn how letters map to sounds and begin to read simple words. Most readers at this stage:

  • Understand letter-sound relationships

  • Can decode regular one-syllable words like cat, map, or pan

  • Begin to comprehend what they read

Children at risk for dyslexia may show a different pattern. They might:

  • Not connect letters with sounds

  • Make reading mistakes that don’t match the letters on the page

  • Struggle to break words into sounds

  • Avoid reading or express frustration

These challenges often suggest difficulties in phonics and decoding—core components of early reading.

2nd Grade and Beyond
Age: 7+

By second grade and up, most children begin to read more fluently and focus on understanding longer texts. Typically developing readers:

  • Use letter-sound knowledge to read unfamiliar words

  • Decode longer, multisyllabic words using word parts

  • Read with enough fluency to focus on comprehension

Children at risk for dyslexia may:

  • Continue to struggle with decoding

  • Read slowly or guess at words

  • Confuse similar-sounding words

  • Avoid reading aloud

  • Show persistent difficulties with spelling and handwriting

At this stage, reading difficulties become more pronounced and can affect a child’s confidence and academic performance if not addressed.
