No. IEPs do not expire. A new IEP must be written annually, or more frequently if necessary, or at parent/guardian/other education rights holder or teacher request to replace the current IEP.[1] If you and the school disagree on placement or services, the last agreed-upon and implemented IEP remains in effect. The disagreements may become the basis for a request for due process.Once you file for due process, your child must remain in their current educational placement until the disagreement is resolved.[2] See Chapter 6, Information on Due Process/ Compliance Procedures.
