This document discusses dyslexia, including informal assessments and signs of dyslexia in young children. It notes that dyslexia occurs in up to 20% of the population and is genetic. Phonemic awareness assessments can help identify potential reading issues in children as young as age 4. Both informal data collection and formal evaluations are recommended to diagnose dyslexia. A formal evaluation should include assessments of background history, cognitive ability, phonemic awareness, decoding/phonics skills, comprehension, fluency, spelling and writing. Schools can determine eligibility for support but cannot diagnose dyslexia. Early intervention is important.
