The central school district obligation for disciplinary changes in placement under the Individuals with Disabilities Education Act (IDEA) is to answer the question of whether the conduct at issue is a manifestation of the individual student's disability. School psychologists often play a key role in this team-based manifestation determination (M-D; also referred to as a manifestation determination review or MDR) based on their specialized expertise and school-based experience. The "yes" or "no" answer to an M-D is largely pivotal for the related IDEA provisions for (a) a functional behavioral assessment (FBA) and behavior intervention plan (BIP); (b) for specified serious code-of-conduct violations (such as possession of a weapon on school premises), a 45-day interim alternative educational setting (IAES); and (c) the location and standards for FAPE. M-D cases typically arise when parents challenge a district's determination that the behavior in question was not a result of the child's disability. The IDEA specifies various procedural requirements for the M-D, such as who must conduct it and when it must be completed. The purpose of this article is to provide an update for the most recent 5 years, specifically from September 2019 to September 2024. This latest snapshot extends to the case law rulings on the applicable procedural requirements.
