The parent has multiple options to respond to the presented IEP (which is developed after the IEP meeting, not before).
The parent can:
Accept in full
Reject in full
Reject portions of the IEP (the rest will be considered accepted). "Stay Put" laws apply to rejected portions if previously held IEP.
Reject what is NOT included in the IEP (write in what hasn't been included under the reject section.)
If any portion of the IEP is rejected, request a meeting to discuss the IEP rejected components.
Sign and date the IEP. The IEP must be returned to the school within 30 calendar days or it is considered rejected.
