Extended School Year (ESY): How Teams Decide and Document It

Quick Answer

ESY is an individualized FAPE decision under 34 CFR §300.106, not an automatic summer program or a disability-category entitlement. Use the student’s actual learning pattern and the state’s criteria. Regression/recoupment can be relevant evidence, but federal law does not establish one universal regression/recoupment formula.

ESY is a FAPE decision, not a summer-program checklist. The team should examine the student's actual learning pattern under the state's ESY criteria and decide whether special education or related services beyond the normal school year are necessary. Federal law does not create one universal regression/recoupment formula, and it bars categorical disability rules or unilateral limits on the type, amount, or duration of ESY services.

What a strong ESY decision includes

ESY is an individualized service/FAPE determination, not an annual goal category. The team may use annual-goal and functional-performance data as evidence, but the ESY record should show the learning pattern, state decision factors, the team’s conclusion, and—if ESY is needed—the specific special education and related services required beyond the normal school year.

Federal anchor: 34 CFR §300.106 makes ESY an individualized FAPE determination and prohibits disability-category limits or unilateral caps on type, amount, or duration.

Regression — loss of a relevant skill over a break: Often considered by states; document the actual measure. Recoupment — time needed to regain prior performance: Compare with the student's typical learning pattern. Critical/emerging skill evidence — impact of interruption at a key stage: Use only as recognized by state/local criteria. Individual FAPE need — team determination under applicable rules: The controlling federal principle.

Organize ESY evidence so the team can see the learning pattern across interruptions: pre-break performance, post-break performance using the same measure, the amount of reteaching or time needed to return to the earlier level, and any relevant critical-skill data recognized by the state's criteria. Under 34 CFR §300.106, the decision is individualized and cannot be limited by disability category or a unilateral cap on type, amount, or duration of ESY services.

The evidence record is easier to interpret when it is paired with progress monitoring, related services, and baseline data.

How to get a baseline

Build the ESY record from the student’s actual pattern across breaks and interruptions. Useful evidence can include performance before a school break, the first data collected after return, the time required to regain previously learned performance, progress on critical emerging skills, and the relationship between interruptions and the student’s ability to receive FAPE.

Regression/recoupment can be relevant, but it is not a universal federal formula. The Department of Education has stated that the specific analysis and standards used to decide whether ESY is needed are left to states, while the decision itself must be individualized. Review your state’s criteria and documentation rules rather than importing a threshold from another state.

Use comparable measures on both sides of a break. A pre-break reading probe and a post-break teacher impression are weak evidence because the measurement changed. If the student had unusual illness, attendance, or service disruption, record that context so the team does not misattribute the change to the break itself.

Example ESY evidence and decisions

The ESY examples show ways to organize evidence, not federal eligibility formulas. Apply the student's current data to the state's ESY criteria and the individualized FAPE question; do not copy a sample recoupment period or service pattern into another student's decision.

Break data — Compare IEP-goal performance immediately before and after scheduled breaks using the same measure. (Condition: same skill measure before and after breaks | Behavior: document loss and return pattern | Criterion: multiple breaks when available) How to measure: progress-monitoring probes.

Recoupment data — Track how much instruction or time is needed for the student to return to the prior performance level after a break. (Condition: post-break re-teaching period | Behavior: measure return to prior level | Criterion: use the state’s applicable ESY standards) How to measure: probe scores and instructional records.

Emerging skill — Document whether a skill that is newly developing is educationally significant and how interruption may affect access, then apply state criteria rather than a blanket rule. (Condition: a documented emerging skill | Behavior: describe current acquisition and impact of interruption | Criterion: individualized team analysis) How to measure: goal trend and instructional records.

Service interaction — Review whether interruption of a related service would materially affect the student’s ability to receive FAPE under the state’s standards. (Condition: current related-service need | Behavior: analyze educational impact of interruption | Criterion: individualized, not disability-category based) How to measure: provider data and IEP progress.

No automatic rule — Do not treat a diagnosis, disability category, or prior ESY placement as automatic eligibility for the next year. (Condition: current student-specific data | Behavior: make a current individualized decision | Criterion: no categorical shortcut) How to measure: IEP team documentation.

Documentation — Record the evidence considered, the team’s conclusion, and the services needed if ESY is required; check state guidance for the governing decision factors and timelines. (Condition: state criteria plus current data | Behavior: document team rationale | Criterion: specific to this student and year) How to measure: meeting notes and written notice as applicable.

Organize the ESY evidence packet

Before the team decides, assemble the data in a way that makes break-related patterns visible. Put pre-break and post-break scores side by side, identify the length of the break, note how much reteaching occurred, and show when the student returned to the prior level if that is part of your state’s framework. Include provider data when interruption of a related service is relevant.

Do not wait for a long summer break if shorter school breaks can provide useful evidence. Winter, spring, or other scheduled breaks may show maintenance and recoupment patterns, though the team must interpret them in context. A single post-break dip is not automatically decisive.

If the team determines ESY is necessary, document the services needed for FAPE rather than copying the regular school-year schedule by default. If the team determines ESY is not required, document the individualized data and state criteria considered.

Keep the ESY discussion separate from convenience or childcare concerns. The educational question is whether the student needs special education and related services beyond the normal school year to receive FAPE. If another summer program exists, do not assume it automatically satisfies an individualized ESY need.

Separate a need for ESY from a need for better school-year instruction

A weak ESY record can blur two questions: whether the student needs services beyond the normal school year to receive FAPE, and whether the current school-year program is sufficiently intensive. Keep those questions separate. If a skill is flat during regular services, first examine instruction, service implementation, attendance, and measurement quality. ESY is not a substitute for fixing an ineffective school-year plan. On the other hand, strong progress during the year does not automatically rule ESY out if individualized evidence shows that a long break is likely to jeopardize meaningful access to the IEP. Document the specific skill, the break-related evidence, and why the team reached its conclusion.

How to write the matching present level

The PLAAFP should contain the skill and learning pattern that matter to the ESY discussion, not a generic statement that the student “regresses over breaks.” Example: “Before winter break, Leah completed 8 of 10 steps in her toileting routine independently across five school days. During the first week after the 12-day break, independence fell to 3–4 steps and returned to the pre-break range after nine instructional days.”

That does not automatically establish ESY eligibility. It gives the IEP Team concrete evidence to apply under the state’s ESY standard and the student’s individualized FAPE needs.

Progress monitoring

If ESY is provided, identify the specific goals, skills, or services the team determined are necessary and collect data during the ESY period. Compare performance with the pre-break and return-to-school record so the team can evaluate whether the planned services addressed the identified need.

Under 34 CFR §300.106, ESY cannot be limited only to particular disability categories or by a unilateral cap on type, amount, or duration. The services must be individualized and provided in accordance with the IEP when necessary for FAPE.

After the next significant break, add the new evidence to the longitudinal record. ESY decisions are prospective; the team should use the best current evidence available rather than treating last year’s decision as permanent.

Common mistakes

Before finalizing an ESY decision section, check the following points against the student's actual data and implementation record:

Calling regression/recoupment the only federal test. Using disability category as an automatic yes/no rule. Imposing a preset summer duration without individualized determination. Comparing unlike skills before and after breaks. Waiting until the last minute to collect data. Presenting a state criterion as though it were federal law.

Close the ESY discussion with a decision record that shows the comparable break data considered, the state criteria applied, and the individualized FAPE rationale. If ESY is required, specify the special education and related services actually needed rather than copying the regular-year schedule automatically. If it is not required, document the evidence supporting that conclusion without inventing a federal numeric cutoff.

FAQ

Is regression and recoupment the federal test for ESY eligibility?

No single regression/recoupment formula appears in 34 CFR §300.106. The federal rule requires an individualized IEP Team determination that ESY is necessary for FAPE and bars disability-category exclusions or unilateral limits on type, amount, or duration. States may use regression/recoupment and other factors, so check current state criteria.

Is ESY the same as summer school?

No. ESY under IDEA is special education and related services provided beyond the normal school year, in accordance with the IEP, at no cost to parents, when the IEP Team determines the services are necessary for FAPE. General summer school can have different purposes, eligibility rules, schedules, and curriculum.

Can a district limit ESY to certain disability categories?

No. 34 CFR §300.106 specifically prohibits limiting ESY services to particular categories of disability. Eligibility must be decided individually. A district also may not unilaterally limit the type, amount, or duration of ESY services; the student's IEP Team determines what is needed for FAPE under the applicable rules.

What kind of data are useful for an ESY decision?

Useful data can include comparable performance immediately before and after breaks, time needed to recoup a skill, progress-monitoring trends, and other factors recognized by the state's criteria. Keep the measurement method and prompt level stable. Anecdotes can add context, but repeated skill data make the learning pattern much easier for the team to evaluate.

When should teachers start collecting ESY data?

Early enough to capture meaningful breaks and avoid a last-minute decision based on memory. If the state or LEA uses pre-break/post-break evidence, plan the probes before scheduled interruptions and use the same measure after return. Because timelines and criteria vary by state, check the current local process rather than inventing a universal deadline.
