Regression
A significant loss of skills that occurs during breaks from school. If your child shows regression, it may support the need for extended school year (ESY) services.
Regression in context
Regression comes up across the IEP process — in your IEP document, during meeting prep, and in the federal rights that protect your child. Rules and timelines can also vary by state — find your state's parent training centers and dispute options in our State IEP Guides.
If this term affects your child's annual goals, test whether they are measurable using our free IEP Goal Checker or follow our step-by-step IEP Annual Review Checklist.

Recoupment
The time it takes for your child to regain skills lost during a break from school. If recoupment takes an unusually long time, it may indicate a need for extended school year (ESY) services.
