Special education students typically need to be reevaluated every three years, but if the IEP team reviews a student's progress and determines that no additional data is needed to determine whether the student continues to be a child with a disability, the school can request permission from the parents to waive the reevaluation.
If the parents agree to waive the reevaluation, the reevaluation deadlines will be pushed back until three years after the date in the Agreement to Waive Reevaluation.
