Extended School Year (ESY) services are often misunderstood, but federal law makes clear that they are a critical component of a student’s right to a free appropriate public education (FAPE) under the Individuals with Disabilities Education Act.
ESY is not simply “summer school,” nor is it limited to a specific time of year. ESY services can be provided at any point when school is not in session, such as summer, winter break, spring break, or other interruptions … if a student’s needs require it. The purpose of ESY is not convenience or enrichment; it is to ensure that a student continues to receive meaningful educational benefit as required by federal law.
ESY is also not limited to group instruction or pre-set programs. Under IDEA, services must be individualized based on the student’s unique needs, as determined by the IEP team. This means ESY can include one-on-one instruction, related services (such as speech, occupational therapy, or behavioral supports), or other specially designed instruction tailored to the student.
Importantly, ESY is not based solely on whether a student shows regression and recoupment difficulties, although that is one factor teams may consider. Federal guidance makes clear that eligibility must be determined on an individual basis and may include multiple considerations, such as:
• The likelihood of significant regression during breaks
• The time it takes to regain lost skills (recoupment)
• The presence of emerging or “breakthrough” skills that could be lost without continued instruction
• The severity of the disability
• Interfering behaviors
• The need for continuity of instruction to make meaningful progress
In particular, “breakthrough skills” are explicitly recognized in federal guidance as a valid reason for ESY services. When a student is on the verge of mastering a critical skill, interrupting instruction could halt progress and deny the student meaningful educational benefit.
Ultimately, ESY is about ensuring that the services in a student’s Individualized Education Program (IEP) remain effective year-round when necessary. Schools cannot apply blanket policies (such as limiting ESY to certain disabilities, grade levels, or program types), nor can they restrict ESY to students who meet only one narrow criterion. Decisions must be individualized, data-driven, and aligned with the legal standard of providing FAPE.
In short: ESY is flexible, individualized, and legally required when needed … not a one-size-fits-all summer program, but a safeguard to ensure continuity of learning and progress for students with disabilities
