Special procedures must be followed when a school disciplines a student with an IEP. Students with active IEPs can only be suspended for up to 10 days before the school must hold a "manifestation determination" meeting to decide if the problem behavior is related to or the result of the student's disability. Additionally, whether or not it is determined that the act was a manifestation of the student's disability, the student may only be removed from their current placement for up to 45 days for specified reasons.
If it is found that the behavior was a manifestation of the students disability, the child cannot be removed from school. Instead the IEP team must conduct a functional behavioral assessment and implement a behavioral plan or modify the existing behavioral plan.
Students who are suspected to have a disability are given some additional protections as well, if the school had prior knowledge. However, parents may request for the child to be evaluated at any time. If the request is made during the time the child is being disciplined, the evaluation must be done in an expedited manner.
