Procedures for Assessment of Dyslexia

The Deer Park Independent School District follows the policies and procedures outlined in the Texas Education Code §38.003. The process established by the district for identification, intervention, and placement concerning dyslexia is in accordance with federal and state guidelines. Students enrolling in Deer Park ISD shall be assessed for dyslexia and related disorders at appropriate times (TEC §38.003 (a)). The appropriate time depends upon multiple factors including the student’s reading performance, reading difficulties, poor response to supplemental, scientifically based reading instruction, teachers’ input, and parents’ or guardians’ input. Additionally, the appropriate time for assessing is early in a student’s career (19TAC §74.28). While earlier is better, students will be recommended for assessment for dyslexia even if the reading difficulties appear later in a student’s school career.

The procedures followed for assessment include:

  • Notify parents or guardians of proposal to assess student for dyslexia.
  • Provide Procedural Safeguards as mandated by IDEA.
  • Obtain parent or guardian permission to assess the student for a specific learning disability with the condition of dyslexia.
  • Evaluate student with a Full Initial Individual Evaluation (FIIE) under IDEA.
