How Often Is an IEP Reviewed in Arizona? Annual, Triennial, and Parent-Requested Reviews

An IEP in Arizona is reviewed at least once a year (the annual IEP review), reevaluated at least every three years (the triennial reevaluation), and can be reopened at any time at your written request as a parent. Federal IDEA sets the floor on these timelines, and Arizona follows the federal standard. The annual review is a chance for the IEP team to look at progress on goals, update services, and adjust the plan for the year ahead. The triennial reevaluation is a deeper look at whether your child still qualifies for special education and what their current needs are. Parent-requested reviews fall in between and exist for the moments when something has changed and you need the team to revisit the plan before the next scheduled meeting.

If you are trying to figure out when your child’s next IEP review is, whether you can request a meeting outside the annual cycle, or what to expect at a triennial reevaluation, this guide breaks each one down.

The Annual IEP Review

The annual IEP review is the most common type of IEP meeting. Federal law requires the IEP team to review the IEP at least once every twelve months. In practice, Arizona schools usually schedule the annual review on or before the anniversary of the most recent IEP signing.

At the annual review, the team typically:

• Reviews progress on each of your child’s current IEP goals
• Discusses what is working and what is not in services and accommodations
• Updates present levels of academic and functional performance
• Develops new goals for the coming year
• Adjusts service minutes, related services, or accommodations as needed
• Discusses placement and least restrictive environment
• Sets the next annual review date

Annual reviews can run anywhere from 45 minutes to 2 hours depending on the complexity of the case and the number of changes being made. You should leave with a copy of the updated IEP, or arrangements to receive it within a few days.

If the school has not scheduled your child’s annual review and the anniversary is approaching, you can send a written request to the case manager or special education director asking that it be scheduled. Schools that miss the annual deadline are in procedural violation, which matters if you later need to dispute services or escalate.

The Triennial Reevaluation

Every three years (at minimum), the school must conduct a full reevaluation of your child to determine whether they still qualify for special education and what their current needs are. This is called the triennial reevaluation, sometimes shortened to “tri.”

The triennial reevaluation is a more comprehensive process than the annual review. The MET (Multidisciplinary Evaluation Team) is reconstituted to review existing data and decide what additional assessments are needed. Sometimes new formal assessments are conducted (cognitive testing, achievement testing, related service evaluations). Other times the team determines that existing data is sufficient and no new assessments are needed.

Three things to know about the triennial:

You can waive new assessments. If you and the school agree that existing data is enough to determine continued eligibility and needs, you can sign a written agreement to skip new formal assessments. This is the school’s prerogative to propose, and yours to agree to or decline.

You can request a triennial earlier than three years. If your child’s needs have changed significantly (a new diagnosis, a major shift in functioning, a new condition), you can request a reevaluation before the three-year mark. The school may or may not agree, but you have the right to ask.

A triennial can result in exit from special education. If the MET determines your child no longer has a qualifying disability or no longer needs specially designed instruction, they may be exited from special education. You have the right to disagree, request an Independent Educational Evaluation, or use the dispute resolution paths (state complaint, mediation, due process).

Parent-Requested IEP Reviews

This is the option many parents don’t realize they have. You do not have to wait for the annual review to ask the team to revisit your child’s IEP. At any time, you can request an IEP team meeting in writing. The school is generally expected to schedule the meeting within a reasonable time frame, often within 30 days.

Reasons parents request mid-year IEP reviews:

• The current services are not working and your child is regressing
• A new diagnosis or medical situation has changed your child’s needs
• A major incident at school (a behavioral crisis, a placement change, a significant injury)
• Accommodations or services are not being delivered (see also: when the school is ignoring the IEP)
• Your child is transitioning between schools or grade levels
• Outside evaluators have produced new data the team should consider
• You want to add or remove services, goals, or accommodations

The request should be in writing. Email is fine. Specify what you want the meeting to address. The school will schedule the meeting and convene the IEP team. If the team meets and changes are made, you should receive an updated IEP or written amendment.

If the school refuses your request for a meeting, that refusal triggers a prior written notice requirement (the school must explain in writing why they refused and what data they considered). A refused meeting request is grounds to escalate.

When to Request a Review Outside the Annual Cycle

Not every concern warrants a full IEP meeting. Some issues can be resolved with a quick conversation or email to the case manager. But you should request a formal IEP review when:

• You have data showing the current plan is not working and minor adjustments won’t fix it
• You want to formally add, remove, or significantly change services or goals
• The placement needs to change
• An evaluation or independent evaluator’s report needs to be discussed and reflected in the plan
• You believe the current IEP needs to be substantially restructured

If you are unsure whether to request a full review or handle it informally, lean toward requesting the review. A formal IEP team meeting produces a written record, gives all required team members a chance to weigh in, and forces a decision on the record. Informal conversations are easier but don’t carry the same procedural weight.

What Happens If the School Misses a Review Deadline

If the school misses the annual review deadline or the triennial reevaluation deadline, that is a procedural violation. Procedural violations are not automatically grounds for major remedies, but they matter when:

• The missed timeline caused harm (your child went without an updated plan that would have changed services)
• The missed timeline is part of a pattern of non-compliance
• You are documenting issues for a state complaint or due process filing

If you notice a missed deadline, raise it in writing with the case manager and special education director. Most missed deadlines are administrative oversights that get scheduled quickly once flagged. Persistent missed deadlines deserve a state complaint.

A Note on Frequent IEP Meetings

Some IEPs warrant more than the minimum review cadence. Children in active behavioral programs, students transitioning between schools or programs, kids whose conditions are changing rapidly, and students whose IEPs are highly contested often benefit from more frequent check-ins. There is no upper limit on how often the team can meet. If your child’s plan needs quarterly check-ins to stay on track, request them.
