Diagnosing Dyslexia

Early Identification

Signs in Preschool and Early School Years

Early identification of dyslexia is crucial for timely intervention. Here are some signs to watch for in preschool and early school-aged children:

Preschool Signs

  • Delayed speech development compared to peers
  • Difficulty learning nursery rhymes or playing rhyming games
  • Trouble recognizing letters and learning the alphabet
  • Difficulty pronouncing words (e.g., saying ‘pasghetti’ for ‘spaghetti’)
  • Persistent baby talk

Early School Years (Kindergarten to Grade 2)

  • Difficulty learning to read
  • Problems with phonemic awareness (difficulty hearing and manipulating sounds in words)
  • Trouble with learning and remembering sight words
  • Slow reading progress
  • Difficulty with spelling and writing

Assessment and Testing

How Dyslexia is Diagnosed

Diagnosing dyslexia involves a comprehensive evaluation that assesses various aspects of a child’s reading and language abilities. The process typically includes:

    1. Initial Screening: Teachers or parents may notice early signs and refer the child for further evaluation.
    2. Comprehensive Evaluation: Conducted by a qualified professional, this assessment includes a variety of tests and questionnaires.

Types of Assessments

Several assessments are used to diagnose dyslexia, including:

  • Phonological Awareness Tests: Assess the ability to hear and manipulate sounds in words.
  • Word Recognition Tests: Measure the ability to recognize words quickly and accurately.
  • Reading Fluency Tests: Evaluate the speed and accuracy of reading connected text.
  • Spelling Tests: Assess the ability to spell words correctly.
  • Writing Tests: Look at the ability to construct written language.
  • Memory Tests: Evaluate short-term and working memory related to language processing.
  • Listening Comprehension Tests: Assess understanding of spoken language.
