Guidance Related to Evaluations: Review of Existing Evaluation Data (REED) and Reevaluation

The Individuals with Disabilities Act (IDEA) 2004 requires a review of existing evaluation data (REED) for students suspected of having a disability(ies) as part of an initial evaluation, if appropriate, or as part of a reevaluation for students with disabilities. This means, before any evaluation a REED must be completed to help determine which specific evaluations, if any, are needed. 

The REED must be conducted by the members of the student’s admission, review, and dismissal (ARD) committee and other qualified professionals. The members review the student’s existing evaluation data to determine the scope of the initial evaluation or reevaluation. This review process does not have to take place in an ARD committee meeting.  

A REED must include the following information: 

  • Previous evaluations 

  • Evaluations and information provided by the parents 

  • Teacher information and observations 

  • Classroom based, local, and state assessments s, if any are needed. 


The committee members must ensure that information obtained from these sources is documented and carefully considered. 

A local education agency (LEA) must reevaluate a student who receives special education services if the LEA determines that the student’s educational or related services needs, including improved academic achievement and functional performance, warrant a reevaluation or if the student’s parent or teacher requests one. The IDEA places time limitations and requirements on when a reevaluation occurs. The ARD committee and other qualified personnel, as appropriate, must complete a REED to help determine what additional data, if any, are needed to determine whether the student continues to be a student with a disability and requires special education and related services and whether changes are needed to the services being provided.
