As spring approaches, IEP teams across the country face one of special education's most consequential decisions: Does this student qualify for Extended School Year (ESY) services? The answer should be grounded in data that demonstrates regression and recoupment patterns.

Understanding ESY Eligibility

Extended School Year services are required under IDEA when a student experiences significant regression during breaks that impairs their ability to benefit from their educational program.

Key Legal Standard

ESY services must be provided when necessary to provide FAPE. The question is not whether summer services would be beneficial, but whether the student will lose critical skills without them.

The Regression/Recoupment Standard

Regression refers to the loss of skills during breaks. Recoupment refers to the time needed to return to pre-break performance. Excessive recoupment time is often more significant than regression itself.

Measure Typical Significant
Skill Level10-20% decrease30%+ decrease
Behavior Frequency1.5x increase2x+ increase
Recoupment Time2-4 weeks6+ weeks

Data Collection Timeline

2 Weeks Before Each Break

Establish clear baseline data for target behaviors.

First Day Back

Resume data collection immediately. Document post-break performance.

Daily Until Recoupment

Track until student returns to baseline. Count the days.

The Bottom Line

ESY decisions should be based on data. Start collecting regression and recoupment data at winter break. When your data tells a compelling story, ESY decisions become clear and defensible.

Take Action

Put what you've learned into practice with these resources.

Key Takeaways

  • ESY eligibility is based on regression and recoupment data, not just severity of disability
  • Begin collecting regression data after winter and spring breaks to establish patterns
  • Document both behavioral and academic regression with specific, measurable data
  • Recoupment time is equally important - track how long it takes to return to pre-break levels
  • Strong ESY justifications connect behavior regression to educational impact
