Your child’s school sent home a letter. It says something about an evaluation. Or maybe you’ve been fighting for services for months and have no idea what’s supposed to happen next — or when.
Arizona’s IEP process has a specific timeline laid out by federal law (IDEA) and state regulations. Schools are required to follow it. Most parents don’t know it exists.
This guide walks you through every major milestone in the Arizona IEP timeline so you can hold your school accountable — and advocate effectively for your child.
What Is the Arizona IEP Timeline?
The Individuals with Disabilities Education Act (IDEA) sets strict deadlines for every step of the special education process.
Arizona follows these federal rules through the Arizona Department of Education (ADE), which oversees all public school districts in the state.
These timelines are not suggestions. They are legal requirements. When schools miss them, parents have the right to file a complaint with the ADE’s Exceptional Student Services (ESS) division.
Here’s the full timeline from start to ongoing services.
Step 1: The Referral — Where It All Starts
The process begins when a child is referred for a special education evaluation. This can happen two ways:
- The school initiates — a teacher or administrator believes your child may need services
- You request it — any parent or guardian can make a written request for evaluation at any time
What to know: The moment you submit a written request for evaluation, the clock starts. Schools cannot ignore or delay acting on a written referral.

Step 2: Prior Written Notice and Consent — 10 Days
After a referral is made, the school must provide you with Prior Written Notice (PWN) — a document explaining what they propose to do (or not do) and why.
You then have the opportunity to provide or deny consent for the evaluation.
Timeline: The school must obtain your written consent before conducting any initial evaluation. You should receive this paperwork promptly after the referral.
What to do: Read the PWN carefully. It tells you exactly what assessments they plan to conduct. If areas are missing (speech, OT, behavior), request them in writing before signing.
Step 3: Arizona’s 60-Day Evaluation Timeline
This is the rule most parents should know cold.
Once you provide written consent for evaluation, Arizona schools have 60 calendar days to complete all assessments and hold an eligibility meeting.
The Arizona Department of Education specifies this timeline under A.R.S. § 15-766. The 60 days includes:
- All individual assessments (psychological, educational, speech-language, OT/PT, behavioral)
- Review of existing records and data
- The eligibility determination meeting where the team decides if your child qualifies
What Can Pause the Clock?
A few limited exceptions exist:
- School vacations — if the 60-day window falls over a scheduled break of 5+ days, those days may not count
- Parent scheduling — if you’re unavailable to schedule the eligibility meeting, the timeline may flex
- Exceptional circumstances — must be documented and justified
Important: Schools sometimes use these exceptions loosely. If you’re approaching the 60-day mark and haven’t received an eligibility meeting invitation, send a written inquiry. Document everything.
Step 4: The Eligibility Determination Meeting
At the end of the evaluation period, the school holds an eligibility meeting. The team reviews all assessment data and decides whether your child qualifies for special education services under one of Arizona’s 13 disability categories (aligned with federal IDEA categories).
If your child qualifies: The team moves immediately into IEP development. In practice, this often happens at a separate follow-up meeting, but the initial IEP must be developed promptly after eligibility is confirmed.
If your child doesn’t qualify: You receive written notice of the decision and your right to dispute it. Don’t accept this outcome without asking for the full evaluation report and reviewing it carefully.
Step 5: The Initial IEP — 30 Days After Eligibility
After eligibility is confirmed, Arizona requires the initial IEP to be developed and implemented within 30 days.
The IEP meeting must include:
- At least one general education teacher
- At least one special education teacher
- A school administrator who can authorize services
- Related service providers (speech, OT, etc.) if relevant
- You, the parent — an equal member of the team
- Your child, when appropriate (especially for older students)
What Should Be in the IEP?
The IEP is a legal document that defines your child’s special education program. Arizona’s requirements mirror federal law:
- Present Levels of Academic and Functional Performance (PLAAFP) — where your child is right now
- Measurable annual goals — specific, trackable targets for the year
- Special education services — what the school will provide and how often
- Related services — speech, OT, PT, counseling, etc.
- Accommodations and modifications — in the general education classroom
- Least Restrictive Environment (LRE) statement — where services will be delivered
- Transition planning — required beginning at age 16 (or earlier in Arizona)
Step 6: Annual IEP Review — Every 12 Months
Once your child has an IEP, it must be reviewed at least once every 12 months. This is called the Annual IEP Review or Annual Review meeting.
The school should notify you of the meeting date in advance and ensure you have time to prepare. You are a full member of the IEP team — not a guest being informed of decisions already made.
What Happens at the Annual Review?
- Review progress on last year’s goals
- Determine if goals were met, partially met, or not met
- Update Present Levels based on new data
- Write new goals for the coming year
- Confirm or adjust services, placement, and supports
What parents often miss: The annual review is the time to push for more. If your child didn’t make sufficient progress, that’s a signal that something in the plan needs to change — not just the goals.
If school services still aren’t enough: Some Arizona families supplement their child’s IEP services with private tutoring or therapy funded through Arizona’s Empowerment Scholarship Account (ESA) program. If you’re already using ESA — or considering it — ESA funds can be used for private tutoring, curriculum, and therapies that go beyond what the school provides. This can be especially valuable during the annual review cycle when you know your child needs more than the IEP is currently offering.

Step 7: Three-Year Reevaluation — Every 36 Months
In addition to annual IEP reviews, Arizona requires a comprehensive reevaluation at least every three years (called the “triennial” or “three-year re-eval”).
The purpose is to determine whether your child still qualifies for special education and whether the current program is appropriate.
Can You Request a Reevaluation Sooner?
Yes. Parents can request a reevaluation at any time if:
- Your child’s needs have significantly changed
- You suspect the current evaluation doesn’t reflect your child’s abilities
- New diagnoses or circumstances have emerged
The school may agree or deny the request, but they must provide a written explanation if they refuse.
Transition Planning: What Arizona Requires Starting at Age 16
Federal law requires transition planning to begin no later than age 16. This means the IEP for the school year your child turns 16 must include a Transition Plan.
Arizona follows this federal requirement, and many districts begin transition discussions earlier — which parents should encourage.
What the Transition Plan Covers
- Post-secondary education goals — community college, vocational training, university
- Employment goals — what kind of work your child aspires to
- Independent living goals — housing, daily living skills, community participation
- Services and activities — what the school will provide to prepare your child
- Agency linkages — connection to Arizona DES/Vocational Rehabilitation, Arizona@Work, and community services
The hard truth: Transition planning is often underdeveloped. If your child’s transition plan is vague or generic, advocate loudly. This plan shapes your child’s life after school.
Key Deadlines to Put on Your Calendar
| Milestone | Deadline |
|---|---|
| Initial evaluation complete | 60 calendar days from written consent |
| Eligibility determination meeting | Within 60-day evaluation window |
| Initial IEP developed | Within 30 days of eligibility |
| Annual IEP review | At least every 12 months |
| Triennial reevaluation | At least every 36 months |
| Transition plan added | IEP year child turns 16 |
When Schools Miss the Deadlines
If your school district misses any of these timelines, you have options:
- Send a written notice — document the missed deadline and request immediate action
- File a State Complaint — submit to the Arizona Department of Education’s Exceptional Student Services division; ADE must respond within 60 days
- Request mediation — a neutral third party helps resolve the dispute
- File for due process — a formal legal proceeding where a hearing officer decides the case
