ESY stands for Extended School Year. These are specialized education services provided to students with disabilities beyond the standard school year, usually during the summer months, to prevent severe skill loss.
What is Extended School Year (ESY)?
Under the federal IDEA law, schools are required to provide a FAPE to all students with disabilities. For most students, this education happens during the standard 180-day school year. However, some children experience significant regression, meaning they lose critical academic or functional skills, when they are out of school for long breaks. To ensure these students still receive a free and appropriate public education, the school must provide Extended School Year services.
It is vital for parents to understand that ESY is not the same thing as traditional summer school. Summer school is generally an optional program designed for general education students to recover failed credits, catch up on missing work, or take enrichment classes. ESY, on the other hand, is exclusively for students with an IEP. It is not meant to teach new concepts or advance the student to the next grade level. Instead, the sole purpose of ESY is skill maintenance. It is designed to keep a child from losing the progress they made during the regular school year.
Who qualifies for ESY?
Not every child with an IEP will automatically qualify for ESY. In fact, it is a highly individualized decision made by the IEP team every single year. The team looks at data collected throughout the school year—particularly after long weekends, winter break, and spring break—to see how the child's brain responds to time away from instruction.
While states have slightly different criteria, the most common standard used to determine ESY eligibility is the "regression and recoupment" model. The IEP team asks two main questions:
- Regression: Does the student lose a significant amount of academic, social, or functional skills during a break in instruction?
- Recoupment: Does it take the student an unreasonably long time to relearn those lost skills when school resumes? (For example, if it takes a child until November to regain the reading skills they had in June, their recoupment time is too long.)
The team can also consider other factors, such as whether the child is at a crucial "breakthrough" point in learning a critical life skill, like independent toileting, speaking their first words, or learning to walk. If pausing instruction for the summer would permanently jeopardize that breakthrough, the child may qualify for ESY regardless of regression data.
How it works in school
Because ESY is highly individualized, it does not look the same for every student. The IEP team must determine exactly what skills are at risk of regression and design a program specifically to maintain those skills. For one student, ESY might mean attending a specialized classroom for half-days, four days a week, to maintain reading and math fluency. For a student with severe autism, it might mean attending a full-day program focused entirely on maintaining behavioral regulation and functional communication.
For another student, ESY might not involve a classroom at all. The team might decide that the child only needs a one-hour session of speech therapy or occupational therapy per week during the summer to maintain their specific skills. The school district must provide these services, including transportation if necessary, completely free of charge to the family.
What parents can do
Because ESY eligibility relies heavily on data, parents need to be proactive. Do not wait until the final IEP meeting in May to ask about summer services. Instead, start asking the special education teacher in January or February what the data shows about your child's progress after winter break. Did they forget their sight words? Did their behavior worsen? Ask the teacher to document these changes.
Parents should also keep their own records at home. If you notice a massive drop-off in your child's abilities, emotional regulation, or communication over the summer or during long holiday breaks, take notes or videos. Bring this evidence to the IEP meeting to support your request for ESY. Remember that the school cannot deny ESY services simply because they lack funding or do not typically run summer programs. If the IEP team determines the child needs ESY to receive a FAPE, the district must find a way to provide it.
Key points for parents
- ESY is designed specifically to prevent the loss of previously learned skills, not to teach new academic material.
- Eligibility is usually based on "regression and recoupment"—how much a child loses during a break and how long it takes to get it back.
- ESY is an individualized service; it could be a full daily program, or it might just be an hour of speech therapy per week.
- The decision must be backed by data collected by the school after holiday breaks throughout the year.
- Like all special education services, ESY is provided at no cost to the family, including necessary transportation.
