Wyoming IEP Annual Review and Three-Year Reevaluation: What the Timelines Require

Two of the most commonly missed compliance deadlines in Wyoming special education involve timelines that are entirely predictable: the annual IEP review and the triennial reevaluation. Unlike the disputes over service quality or staffing credentials, these violations are often straightforward to identify and document — and because the dates are set in the IEP itself, there is no ambiguity about when the district was supposed to act.

The Annual IEP Review

Under Wyoming Chapter 7 Rules and IDEA, the IEP must be reviewed at least once every 12 months. This is the minimum frequency. The team may meet more often, and parents can request an IEP meeting at any time if the child's needs change or the program is not working. But the district is required to initiate at least one review meeting per year.

The 12-month clock typically runs from the date the last IEP was put in place. If your child's IEP was written on March 15, the district should hold the annual review meeting and complete an updated IEP no later than March 15 of the following year.

What must happen at the annual review:

• Review of current IEP goals and progress toward those goals
• Review of the present levels of academic achievement and functional performance
• Updates to goals, services, and supports as needed based on current data
• Review of whether placement remains appropriate
• Confirmation of the continued provision of FAPE

An annual review is not a rubber-stamp process. It should be driven by current data — progress monitoring reports, service logs, formal assessments if warranted, and observations from general education teachers. If the IEP team is meeting but simply rolling over the same goals without meaningful discussion of progress data, that may indicate the annual review is procedurally compliant but substantively inadequate.

What Happens If the Annual Review Is Missed

If the 12-month deadline passes without the district convening an annual review meeting, the existing IEP does not automatically expire. Your child continues to receive services under the most recent IEP. However, a missed annual review is a procedural violation of Wyoming Chapter 7, which can be reported to the WDE as a state complaint.

More practically, a missed annual review often means missed opportunities to update services, goals, and placement based on how your child has grown or where they've plateaued. If you notice that your child's IEP review date has passed, send a written request to the special education director asking for the annual review meeting to be scheduled immediately. Document the date of your request.

The Three-Year Reevaluation (Triennial)

Under Wyoming Chapter 7 Rules, the district must reevaluate each student with a disability at least every three years. This reevaluation — the "triennial" — determines whether the student continues to have a disability and whether their educational needs have changed.

The triennial must be completed within three years of the last evaluation. If your child's initial evaluation was conducted in October 2022, the triennial reevaluation must be completed no later than October 2025. The same 60-calendar-day timeline that applies to initial evaluations applies to reevaluations: from parental consent to completed reevaluation, 60 calendar days.

The triennial does not automatically require a full battery of new testing. The IEP team, including the parent, reviews existing data and determines what additional data, if any, are needed. If the team determines that no additional assessments are needed and both the parent and district agree, the reevaluation can be completed without new testing. This agreement must be documented in writing.

You can also request a reevaluation before the three-year mark if you believe your child's needs have changed significantly — for example, if a new diagnosis has emerged, if the current program is not producing progress, or if you believe the original evaluation was incomplete.

Timing Reevaluation Strategically

Because reevaluation results inform IEP development, the timing of when a triennial happens in relation to the school year matters. A reevaluation completed in May may drive IEP updates that take effect in the fall — a potentially long gap between data and service adjustment.

If your child's triennial is coming up and you want it to inform specific IEP changes — such as a placement change, the addition of a new service, or a change in disability category — consider requesting the reevaluation early enough that results will be available and actable before the annual review meeting.

Conversely, if the district is suggesting that it will reevaluate and use the results to reduce services, you have the right to participate meaningfully in determining what the reevaluation will assess and who will conduct it. If you disagree with the reevaluation results, you have the right to request an Independent Educational Evaluation (IEE) at public expense.

Connecting Annual Reviews to Reevaluation Data

The strongest IEP meetings occur when annual review discussions are grounded in real data. When the annual review overlaps with or closely follows the triennial, the team should use current assessment results to update all components of the IEP.

If your child has been on the same goals for two consecutive annual reviews without meaningful progress, that is a signal worth raising. It may mean the goals are inappropriate, the services are insufficient, or the program is not working. A request for a reevaluation outside the triennial cycle is justified when existing data is no longer an accurate reflection of the child's current performance.

For documentation templates to request annual reviews, trigger early reevaluations, or dispute reevaluation results, the Wyoming IEP & 504 Advocacy Playbook provides the Wyoming-specific language and Chapter 7 citations that move these requests from informal to legally documented.
