An IEP gets a light review every year, but every three years it gets something deeper: the triennial reevaluation. Children change a lot in three years, and the triennial exists to make sure the plan keeps pace with the child.
Deeper than the annual review
Where the annual review mostly updates the plan, the three-year reevaluation steps back and asks bigger questions about your child — is the picture the plan is built on still accurate, and does it still fit who your child has become? It keeps the plan from running on a snapshot that's quietly gone out of date.
The federal rule is a floor
Your child must be reevaluated at least once every three years. That word "at least" matters — three years is the longest the school can go without taking a fuller look, not a fixed schedule it must wait for. The reevaluation doesn't always mean a full battery of new testing; the team reviews what it already has and decides what additional information, if any, it needs. But the obligation to revisit your child's eligibility and needs on this cycle is a firm one.
The one way it can be skipped
The three-year reevaluation can be skipped only if both you and the school agree, in writing, that it isn't necessary. That option exists for good reasons — sometimes a child's situation is stable and everyone genuinely agrees fresh evaluation would add little. But it takes agreement from both sides, which means you have a real say. The school can't waive the reevaluation on its own, and your signature is part of what makes skipping it legitimate.
A maximum, not a minimum
The three-year mark is a maximum — you don't have to wait for it. If you believe your child's needs have changed, or the current plan no longer fits, you can request a reevaluation sooner. There's a reasonable limit: reevaluations generally happen no more than once a year, unless you and the school agree otherwise. But within that limit, you hold a real lever — if a new diagnosis or a big change at school has shifted things, a mid-cycle request is a legitimate and useful tool.
What a reevaluation examines
The team revisits the core questions, looking at how much progress has been made, whether goals should change, and whether the services still match the child.
- Does your child still have a disability under the law?
- Do they still need special education because of it?
- What are their present needs now?
In practice, it's a chance to catch things the annual reviews may have glossed over — a need that's grown, a service that's no longer helping, or an area no one has looked at closely in years.
Don't waive it casually
Don't treat waiving the reevaluation as a routine box to check. If the school suggests skipping it and asks you to sign an agreement that it's unnecessary, it's completely fair to pause. A reevaluation is one of your best built-in opportunities to get a fresh, thorough look at whether the plan is still right — and giving that up casually can let quiet problems go unexamined for years.
Before I agree to skip the reevaluation, I'd like us to actually discuss whether new information would help. Can we talk it through first?
