Illinois IEP Annual Review and Triennial Reevaluation: What Parents Need to Know

The IEP your child has today will not be the same document they need in three years. Children change. Goals get met — or don't get met. Services that made sense in second grade may no longer fit in fifth. The annual review and triennial reevaluation are the mechanisms Illinois law gives you to formally update the plan. Most parents walk into these meetings underprepared and leave with an IEP that looks nearly identical to last year's.

You don't have to accept that outcome.

The Annual Review: Once a Year, Minimum

Under IDEA and 23 Illinois Administrative Code Part 226, the IEP team must convene at least once per year to review and update the IEP. Illinois districts are required to hold this meeting and give you proper notice ahead of time.

The annual review is a chance to:

• Evaluate progress toward the current IEP goals
• Update the PLAAFP (Present Levels of Academic Achievement and Functional Performance) to reflect where the child is now
• Write new goals for the upcoming year
• Adjust service hours and placement if needed
• Add or remove accommodations

The key word is "at least." You don't have to wait for the annual review if you believe the IEP isn't working. You have the right to request an IEP meeting at any time by submitting a written request to the school. The district must respond, though they are not required to reconvene within a specific timeframe outside of the annual review window.

What to Bring to the Annual Review

The most effective parents at annual review meetings come with data. Not impressions — data.

Progress notes and report cards. Review all progress reports sent home during the year. If the IEP listed quarterly progress reporting, you should have 3-4 data points per goal. Bring them.

Your own observations. You see your child every evening and every weekend. You know what's hard, what's getting easier, and what hasn't moved. Write down specific examples in the weeks before the meeting.

Questions about goals that weren't met. If a goal was not met or was only "emerging" at year-end, ask specifically: why? What instructional approach was used? Was the goal being addressed with fidelity? Were there staffing gaps?

A draft of what you want for next year. You don't have to wait for the school to propose. Write down what you believe your child needs — whether that's an increase in speech therapy minutes, a new reading goal based on where they are now, or an assistive technology evaluation. Bring that list in writing.

The Triennial Reevaluation: Every Three Years

In addition to annual reviews, Illinois law requires a full reevaluation of the child's eligibility and needs every three years. This is the triennial reevaluation (sometimes called a "tri" or "3-year re-eval").

The purpose of the triennial is to:

• Determine whether the child continues to be eligible for special education
• Update the data about the child's current levels of performance
• Identify any new or changed needs that weren't present at the last evaluation

What the Triennial Process Looks Like

The district must notify you of the upcoming triennial and provide a consent form for the new evaluation. You have the right to review and comment on the evaluation plan.

Before conducting new assessments, the team reviews existing data — current IEP progress notes, classroom observations, and previous evaluations. They may determine that some domains don't require new formal testing if existing data is sufficient. Or they may identify areas that need updated assessment.

You have the right to request that additional areas be evaluated during the triennial if you believe the child's needs have evolved. For example, if a child originally evaluated only for learning disabilities has developed significant anxiety that affects school performance, you can request that the social/emotional domain be included in the triennial.

Can the Triennial Find My Child Ineligible?

Yes. If the data no longer supports eligibility under the applicable disability category, the team can determine that the child no longer qualifies for special education services. This is not common, but it happens — particularly for children with speech/language impairments who have made significant progress.

Before agreeing to discontinue eligibility, review the evaluation data carefully. A child who has made progress because of an appropriate IEP may still need ongoing support to maintain that progress. "Progress" is not the same as "no longer needs services."

If you disagree with a determination that your child is no longer eligible, you have the same rights as with any evaluation: you can request an IEE at district expense, file a state complaint with ISBE, or request mediation or due process.

Can You Request an Earlier Reevaluation?

Yes. The three-year cycle is the maximum interval, not the minimum. You can request a reevaluation at any time — for example, after a new diagnosis, after a significant change in the child's performance, or if you believe the current evaluation is outdated and no longer reflects your child's needs.

The district can also initiate an earlier reevaluation if it believes the child's needs have changed. However, the district cannot conduct a reevaluation more than once a year without your agreement.

What "Consent" Means in the Reevaluation Context

For initial evaluations, your written consent is required before the district can proceed. Reevaluations are slightly different. If the district has notified you of the upcoming reevaluation and proposed an evaluation plan, and you do not respond, the district may proceed after a reasonable time. This is different from the initial evaluation, where they cannot proceed without written consent.

However, you always have the right to refuse a reevaluation. If you don't believe a new evaluation is needed, you can decline in writing. The existing IEP remains in effect.

Using the Annual Review to Change Placement

The annual review is one of the clearest opportunities to formally request a change in placement. If you believe your child needs a more intensive setting — or if you believe they're ready to move to a less restrictive environment — bring documentation and make the request at the meeting.

The district must consider your request. If they disagree with your proposed placement change, they must issue a Prior Written Notice explaining the basis for their decision. A verbal "we don't think that's necessary" is not sufficient.

Changes in placement, whether more or less restrictive, must always be based on the IEP team's determination of what is appropriate for the child in the Least Restrictive Environment.
