This monograph presents an analysis of issues related to provision of extended school year (ESY) programs and services for students with disabilities. It discusses major court decisions that have established the case law that governs this area of special education. It also considers issues of eligibility, notice and timing requirements, and the content and duration of ESY services. An overview of state regulations is given. The final section of the document contains relevant excerpts from the special education regulations of 22 states. The report concludes that case law and policy interpretations by the Office of Special Education Programs have established the requirement that ESY services be provided for students with disabilities when the Individualized Education Program team decides that the child's needs warrant such additional programming. Educators are urged to address the following concerns in making these decisions: whether the child's current program is based on individual needs; the nature and severity of the child's disability; likelihood and severity of regression during an interruption in programming; likelihood of recouping such losses within an acceptable period of time; likelihood of failing short-term objectives without extended programming; and appropriate types of ESY instruction.
