IEP Timelines and Deadlines in Michigan

Key takeaways

  • Initial evaluations must be completed within 30 school days of your written consent, and an IEP must be developed within 30 calendar days after your child is found eligible for services.
  • Annual IEP reviews happen every 12 months, and you can request a meeting to review or revise the IEP at any time—you don't have to wait for the anniversary date.
  • If the school misses a deadline, start by documenting everything and sending a polite written follow-up; escalate to the district director if needed, or file a state complaint with Michigan's Department of Education.
  • Your child must be reevaluated at least every three years (triennial review) to confirm they still qualify for special education and their IEP meets their needs.
  • Always request evaluations and important communications in writing to create a clear, dated record that protects your child's right to timely, appropriate special education services.

Understanding the IEP timeline deadlines Michigan families need to know can feel overwhelming — especially when you're already juggling appointments, paperwork, and your child's daily needs. The good news: these deadlines exist to protect your child's right to timely services, and once you know them, you can work confidently alongside your school team to make sure nothing falls through the cracks.

This guide walks you through every major checkpoint in the Michigan IEP process, from the moment you first ask for an evaluation to the annual review that keeps the plan current.


Why Timelines Matter for Michigan Families

Federal law — specifically the Individuals with Disabilities Education Act (IDEA), 20 U.S.C. § 1400 et seq. — gives every eligible child the right to a Free Appropriate Public Education (FAPE) (20 U.S.C. § 1401(9); 34 C.F.R. § 300.17). FAPE means specially designed instruction and related services provided at no cost to your family, tailored to your child's unique needs.

Timelines are the mechanism that makes FAPE real. Without enforceable deadlines, evaluations could drag on indefinitely and services could be delayed for months. Knowing these dates puts you in the driver's seat.


Step 1: Requesting an Initial Evaluation

Your journey typically begins with a request for an initial evaluation — a formal ask to determine whether your child qualifies for special education services.

  • Who can request it? You, as the parent or guardian, or the school district itself (34 C.F.R. § 300.301).
  • How to request it: Submit your request in writing to your child's principal or the district's special education director. Date the letter and keep a copy.
  • Your right is protected by: 20 U.S.C. § 1414(a)(1); 34 C.F.R. § 300.301.

Tip: A written request starts the clock. A conversation in the hallway does not. Always follow up a verbal conversation with a dated written request — an email with a read receipt works well.


Step 2: The District Responds — Prior Written Notice

Once the district receives your request, they must respond in writing before taking any action (or deciding not to act). This response is called Prior Written Notice (PWN).

  • What PWN must include: The action the district proposes or refuses to take, the reasons why, the evaluation procedures they plan to use, and your procedural safeguards as a parent.
  • Legal basis: 20 U.S.C. § 1415(b)(3), (c)(1); 34 C.F.R. § 300.503.

PWN is not just paperwork — it is your record of what the district agreed to do and when. Read it carefully, and contact the special education office if anything is unclear or missing.


Before any evaluation can begin, the district must obtain your written consent. This is a meaningful protection: you have the right to review what the district plans to assess and agree (or ask questions) before the process moves forward.

Once you sign and return the consent form, the evaluation clock officially starts.


Step 4: Completing the Initial Evaluation — Michigan's 30-School-Day Rule

This is one of the most important Michigan-specific deadlines to know.

Michigan requires the district to complete the initial evaluation within 30 school days of receiving your signed consent (Mich. Admin. R. 340.1721b).

A few important clarifications:

  • School days, not calendar days. Weekends, holidays, and school breaks do not count. A request signed just before winter break, for example, will take longer in calendar time than one signed in October.
  • "Complete" means a full evaluation report, covering all areas of suspected disability, conducted by qualified professionals.
  • The evaluation must assess your child in all areas related to the suspected disability — academics, behavior, communication, motor skills, and more, as appropriate.

Keep track: Write the date you signed consent on your calendar. Count forward 30 school days (you can use your district's academic calendar to skip non-school days). That is your deadline.


Step 5: The IEP Meeting — Convening After Eligibility Is Determined

Once the evaluation is complete, the team meets to review the results and determine eligibility. If your child is found eligible, the IEP meeting should be convened promptly.

Key points:

  • The IEP must be in effect at the beginning of the school year for returning students, or as soon as possible after eligibility is determined for newly identified students.
  • You are a full member of the IEP team. The school must schedule the meeting at a mutually agreed-upon time and place and give you adequate notice.
  • If the proposed meeting time does not work for you, ask to reschedule — do not simply skip the meeting.

Step 6: Annual IEP Review

Every IEP must be reviewed and updated at least once per year. This is called the annual review.

  • The purpose is to assess your child's progress toward their current goals and update the plan as needed.
  • You can request a meeting to review or revise the IEP at any time — you do not have to wait for the annual review date if your child's needs change.
  • The district must give you written notice of the meeting and document your participation.

Step 7: Reevaluation — Every Three Years

Beyond the annual IEP review, your child must be reevaluated at least every three years (often called the "triennial" or "three-year re-eval") to confirm continued eligibility and update the understanding of your child's needs.

  • You may also request a reevaluation sooner if you believe your child's needs have changed significantly.
  • The district may not conduct a reevaluation more than once per year unless you and the district agree otherwise.

What to Do If a Deadline Is Missed

If you believe a deadline has passed without action, stay calm and start with a direct conversation. Most delays are administrative, not intentional.

Practical steps:

  1. Document everything. Pull out your dated consent form, emails, and any PWN you received.
  2. Send a polite written inquiry to the special education director, noting the date consent was signed and asking for an update.
  3. Request a meeting to discuss the delay and establish a new, agreed-upon timeline.
  4. Contact the Michigan Department of Education (MDE) Office of Special Education if the issue is not resolved — they handle state complaints.
  5. For serious concerns — especially if delays are causing your child to miss needed services — consult a qualified special education attorney or advocate who knows Michigan law. This guide provides educational information, not legal advice.

A Note on Parental Rights in Michigan

Throughout this entire process, you have the right to:

  • Receive all notices in your native language or primary mode of communication.
  • Bring a support person to any IEP meeting.
  • Request an Independent Educational Evaluation (IEE) if you disagree with the district's evaluation.
  • Receive a copy of your procedural safeguards notice — a document that explains all of your rights under IDEA — at least once per year and at key points in the process.

You are not just a bystander in your child's education. IDEA was written with you as an essential team member.

Frequently asked questions

How long does Michigan have to complete my child's initial evaluation after I give consent?

Michigan requires the district to complete the initial evaluation within 30 school days of receiving your signed parental consent, under Mich. Admin. R. 340.1721b. Note that 'school days' excludes weekends, holidays, and school breaks, so the calendar-day count can be longer depending on the time of year.

Does my evaluation request have to be in writing?

Yes — submitting your request in writing is strongly recommended because it creates a clear record and officially starts the timeline. A dated letter or email to the district's special education director or your child's principal is sufficient. A verbal conversation alone does not reliably start the clock.

Can I request an IEP meeting any time, or only at the annual review?

You can request an IEP meeting at any time — you do not have to wait for the scheduled annual review. If your child's needs change, a new goal is needed, or you have concerns about the current plan, simply submit a written request to the special education director asking to convene the team.

What is Prior Written Notice (PWN) and when must the school provide it?

Prior Written Notice is a written document the school must provide before it takes — or refuses to take — any action related to your child's evaluation or IEP. It must explain what the district proposes to do (or not do), why, and what your rights are. The legal basis is 20 U.S.C. § 1415(b)(3), (c)(1) and 34 C.F.R. § 300.503.

What happens if the school misses the 30-school-day evaluation deadline?

Start by documenting the timeline and sending a written inquiry to the special education director. If the issue isn't resolved, you can file a state complaint with the Michigan Department of Education Office of Special Education. For significant delays affecting your child's access to services, consulting a qualified special education attorney or advocate is a good next step.

How often does my child's IEP need to be reviewed and updated?

An IEP must be reviewed and updated at least once every 12 months (the annual review), and your child must be fully reevaluated for continued eligibility at least every three years. You may request a review or reevaluation sooner if your child's needs change significantly.
