When a special education student is suspended for disciplinary reasons for more than 10 days, the suspension constitutes a change of placement. Relevant members of the IEP team must meet to determine whether the student's conduct was a manifestation of his disability. That determination must take place within 10 school days of the decision to change the placement.
Many parents face a similar dilemma with disciplinary action against their special needs child: We went to an IEP labeled a "manifestation determination," and the team said the child's behavior was not manifestation and my child is now being subjected to disciplinary action. Most have a million questions, but most prevalent is "why was the behavior not a manifestation?"
