Wisconsin Extended School Year (ESY): When Your Child Is Entitled to Summer Services

The school year ends in June and your child loses weeks of progress over the summer. By the time September arrives, the IEP team is back to covering ground that was already mastered in May. You've heard other parents mention "ESY" — extended school year services. But the school has never brought it up. Are you supposed to ask?

Yes. And if your child meets the criteria, the district is required to provide ESY services regardless of whether you asked.

What ESY Is (and What It Isn't)

Extended School Year (ESY) services are special education and related services provided beyond the regular school year, usually in summer months, to students whose IEP teams determine the services are necessary to provide FAPE. ESY is not the same as summer school. ESY is individualized, drawn from the student's existing IEP goals, and provided because the student's disability causes them to regress significantly over breaks in instruction and then requires an unreasonable amount of time to recoup that lost progress.

ESY decisions are made by the IEP team — and under IDEA and Wisconsin regulations, the team is required to make this determination for every student, every year. The district cannot have a blanket policy saying "we offer ESY only to students with severe disabilities" or "ESY is only for students who can access our summer school program." ESY is an individualized determination.

The Legal Standard in Wisconsin

Wrightslaw's summary of ESY caselaw identifies regression and recoupment as the primary standard most courts and hearing officers apply — though other factors are also considered. The IEP team must determine whether the student will experience significant regression in critical skills during the break and whether recovery to pre-break performance levels will take significantly longer than the typical student. When the regression is substantial and the recoupment period is long relative to the length of the break, ESY is required.

Wisconsin applies this standard under federal IDEA regulations and PI 11. ESY denial on the basis of budget constraints, program availability, or the student's disability category is not legally permissible.

Other factors IEP teams may consider:

• The degree of progress the student is making toward IEP goals and whether that progress could be jeopardized by an extended break
• Emerging skills or critical learning periods — some skills are particularly vulnerable during specific developmental windows
• The predictability of regression based on prior school year transitions

How to Request ESY Services

If your child's IEP team has not addressed ESY, bring it up at the annual IEP meeting — or request an IEP meeting specifically to discuss it. Submit a written request before the meeting so there is a paper trail:

"I am requesting that the IEP team consider my child's need for Extended School Year services as part of the IEP planning process. Based on [brief description of regression or skill loss observed during previous breaks], I believe [student name] may qualify for ESY under IDEA and Wisconsin regulations. Please ensure this topic is on the agenda for our upcoming IEP meeting."

At the meeting, ask for data. What do the progress notes show about skill levels in May versus September? Does the district have data from previous transitions that documents regression? If data is limited, ask for a data-collection protocol to monitor your child over the next break period so the IEP team has objective information for next year's decision.

What to Do If ESY Is Denied

If the IEP team denies ESY, they should document the decision in the IEP and issue Prior Written Notice (Form M-1) explaining the basis for the denial. If they haven't done either, request PWN in writing.

Review the denial carefully. If the stated reason is budget constraints, lack of program availability, or a categorical policy excluding your child's disability from ESY, those are potentially actionable violations. File a DPI state complaint documenting that the district applied a blanket rule rather than making an individualized determination.

If the reason is that the data doesn't support regression, but you have observational evidence — teacher notes, parent observations, evaluation results from September showing significant skill loss — you can challenge the factual basis for the denial. A compensatory education request for past summers where ESY should have been provided but wasn't is also a viable strategy.

ESY and the Compensatory Education Connection

If your child has experienced significant regression over multiple summer breaks and the district never addressed ESY eligibility, there is a potential compensatory education argument. IDEA and Wisconsin regulations do not limit compensatory services to failures during the regular school year — they extend to any period where FAPE was not provided, including summers when ESY was required but not offered.

The relevant framework comes from DPI Information Update Bulletin 20.01, which addressed additional services for pandemic-related regression and recoupment. While focused on COVID closures, the underlying standard — that the IEP team must make individualized determinations about regression and provide services to address it — applies equally to ESY decisions in normal school years.

ESY decisions get made at the IEP table, and parents who know the standard can push back on denials with data and legal citations. The Wisconsin IEP & 504 Advocacy Playbook includes an ESY request letter, questions for the IEP team, and a compensatory education template for missed ESY services.
