This text provides teachers and administrators with an understanding of the legal requirements of the IEP under law, including clarifications of how much benefit an IEP must provide based on the recent United States Supreme Court’s 2017 Endrew F. decision on the meaning of a free appropriate public education (FAPE). The book uses a case study and scenario format to clarify these legal constructs. Step-by-step, the component requirements of the IEP will be explained, and checklists of considerations, references, and exemplars will be provided for each section. Preservice and in-service teachers and administrators will find this book a useful guide and reference for the development of IEPs.
