Allegations of improper discipline are commonly the focus of special education litigation filed against school districts. Because ignorance of the law is no defense, administrators and educators must understand special education law. Yet many educators receive little to no legal training. To address the lack of training and prevent future litigation, this article describes why educators must understand the law surrounding the discipline of students with disabilities, explains the relevant legal concepts, and provides case-based instruction that can be used to teach educators how to comply with federal disability law. University instructors, special education directors, principals, and teachers--regardless of their legal knowledge--can implement the case-based instruction to teach preservice and in-service educators about the federal requirements surrounding manifestation determination, the 10-day rule, unidentified students with disabilities, IAES, emergency exceptions for immediate removal, PBIS, and restraints and seclusion.
