Triennial Review
A comprehensive reevaluation that occurs every three years to determine if your child continues to qualify for special education and whether their services need to change.
Triennial Review in context
Triennial Review 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.
