Students must be re-evaluated for eligibility for specially designed services every:

Students receiving specially designed services under the Individuals with Disabilities Education Act (IDEA) must be re-evaluated for eligibility every three years. This three-year re-evaluation is essential for several reasons. It ensures that each student continues to meet the criteria for special education services based on current data reflecting their needs and progress. This periodic re-assessment is crucial to verify that the educational interventions remain appropriate and effective, allowing for adjustments to be made if necessary.

Moreover, the re-evaluation process is designed not only to confirm ongoing eligibility but also to gather fresh insights into the student's developmental and educational progress, which can help educators tailor support to benefit the student optimally. Hence, the three-year timeline strikes a balance between ensuring the adequacy of support and minimizing unnecessary disruptions in a student's educational experience.
