RE: Name of Child ______________
Parent referral for multidiscplinary evaluation
Dear Mr/s. _______________________:
Our son/daughter is experiencing academic and/or behavioral problems in school. S/he is ___ years old and attends ______ School. It is requested that Child's Name be scheduled for a Full and Initial Evaluation in conjunction with the Individuals with Disabilities Education Act (IDEA) to determine if s/he is eligible for special education and related services. It's my understanding this is a multidiscplinary evaluation.
It is also my understanding that there are various timelines involved in the overall IDEA process. At your earliest convenience, please forward them to me at the address below.
We look forward to receiving an evaluation plan within 10 days of this request. It will be necessary that we receive a copy of the Reevaluation Report together with subtest scores one week prior to the IEP meeting being scheduled. Depending on the language utilized in the report(s), for clarification purposes, it may also be necessary to schedule pre-IEP meeting(s) with the diagnostician(s) and other evaluator(s).
This letter is parent consent for the evaluation. If additional information is needed, please contact me immediately.
Sincerely,
Your Name
