IEP Timelines and Deadlines in Washington

Understanding the IEP timeline deadlines in Washington can feel overwhelming — especially when you're also managing therapies, school pickups, and a hundred other things. But knowing exactly what has to happen, and when, puts you in a much stronger position to make sure your child gets the support they need. This guide walks you through every major deadline, in plain language, from the moment you first ask for an evaluation all the way through your child's annual IEP review.

Why Deadlines Matter

Special education timelines aren't just bureaucratic boxes to check. They are legally protected rights under the Individuals with Disabilities Education Act (IDEA), a federal law (20 U.S.C. § 1400 et seq.), and under Washington's own special education rules (WAC 392-172A). When timelines are followed, children get evaluated quickly, services start on time, and families stay informed every step of the way. When timelines slip, children can lose months of critical support — and that's time they can never get back.

Step 1: Requesting an Initial Evaluation

Everything begins with a referral — a formal request asking the school district to evaluate your child to see if they qualify for special education services.

Who can make a referral?

• A parent or guardian (in writing is best)
• A teacher or other school staff member
• A state agency or outside provider

Your right to request an evaluation is protected under 20 U.S.C. § 1414(a)(1) and 34 C.F.R. § 300.301. You do not need a doctor's note, a diagnosis, or the school's permission. Simply write a letter to your child's principal or special education coordinator stating that you are requesting a special education evaluation and why you have concerns.

Pro tip: Always date your request and keep a copy. The clock on Washington's evaluation deadline starts ticking from the date the district receives your written request (or the date the district makes its own referral).

Step 2: The District's Response — Consent and the Evaluation Window

After receiving a referral, the district must take two actions before the evaluation can begin:

1. Provide Prior Written Notice (PWN): The district must give you written notice explaining whether it agrees to evaluate your child — or why it is refusing. This notice must describe what the district proposes or refuses to do and why. PWN is required under 20 U.S.C. § 1415(b)(3), (c)(1) and 34 C.F.R. § 300.503. In plain terms: the school cannot just say "no" verbally. They must put it in writing with a clear explanation.

2. Obtain your written consent: Before any evaluation takes place, the district must get your informed written consent. You have the right to review the proposed evaluation plan before signing.

Step 3: The 35-School-Day Evaluation Deadline

This is the most important deadline in the entire process, and Washington is very specific about it.

Once you give written consent for the evaluation, the district has 35 school days to complete the full evaluation and provide you with a written evaluation report (WAC 392-172A-03005).

Important details about this window:

• The clock runs on school days, not calendar days. Breaks, holidays, and non-instructional days do not count.
• The evaluation must be comprehensive — covering all areas of suspected disability (academics, communication, motor skills, behavior, social-emotional needs, etc.).
• It must be conducted by a multidisciplinary team using a variety of assessment tools, not a single test.
• The district must give you a copy of the written evaluation report before the IEP meeting so you have time to review it.

If your child is suspected of having a specific learning disability, additional documentation requirements apply, but the 35-school-day window still governs completion.

Step 4: The Eligibility Meeting

After the evaluation is complete, the team — including you — meets to review the results and decide whether your child is eligible for special education services. This meeting must happen within the 35-school-day window or shortly after the evaluation report is provided.

If your child is found eligible, the team moves directly into IEP development (this is often done in the same meeting, or a follow-up meeting is scheduled promptly).

If your child is found not eligible, the district must still provide you with a Prior Written Notice (PWN) explaining that decision and your options — including the right to request an Independent Educational Evaluation (IEE) at public expense if you disagree.

---

Step 5: Developing the Initial IEP

Once eligibility is confirmed, the team must develop and implement your child's first IEP. Under IDEA, a Free Appropriate Public Education (FAPE) — defined in 20 U.S.C. § 1401(9) and 34 C.F.R. § 300.17 — must be available to every eligible child. FAPE means your child receives specially designed instruction and related services at no cost to your family, tailored to their unique needs.

Key points about the initial IEP:

• Services must begin as soon as possible after the IEP is signed — delays in implementation are not acceptable.
• You are a full member of the IEP team, not just an observer. Your input on your child's strengths, needs, and goals matters and must be considered.
• You must receive a copy of the completed IEP.

---

Step 6: Annual IEP Reviews

Once an IEP is in place, it must be reviewed at least once every 12 months (annually). This is sometimes called the "annual review" or "annual IEP meeting."

What the annual review covers:

• Progress on current goals
• Whether goals need to be updated or replaced
• Any changes to services, supports, or placement
• Your continued concerns and priorities as a parent

The 12-month clock runs from the date the current IEP was finalized — not from the school year calendar. Schools should contact you well in advance (usually 2–4 weeks) to schedule this meeting. You can also request a meeting at any time if you have concerns that can't wait for the annual review.

---

Step 7: Reevaluation — Every Three Years

In addition to annual IEP reviews, your child must be reevaluated at least every three years (sometimes called a "triennial" or "three-year re-eval") to make sure they still qualify for services and that their needs are accurately reflected. The same 35-school-day evaluation window applies.

You or the district can request a reevaluation sooner if circumstances change — for example, if your child's disability or needs shift significantly.

Eligibility determination meeting	Within or immediately after the evaluation window
Initial IEP developed and services begin	As soon as possible after eligibility is confirmed
Annual IEP review	At least every 12 months
Reevaluation (triennial)	At least every 3 years

What to Do If a Deadline Is Missed

If you believe a deadline has been missed, start with a calm, direct conversation with the special education coordinator. Ask for the timeline in writing. Most delays are administrative and can be resolved quickly once both sides are looking at the same calendar.

If the concern isn't resolved, you have several options under IDEA and Washington state rules:

• File a state complaint with the Washington Office of Superintendent of Public Instruction (OSPI), which investigates procedural violations.
• Request mediation, a free and voluntary process to resolve disagreements.
• Request a due process hearing for more formal disputes.

For anything involving a due process hearing, a manifestation determination, or suspected retaliation, consulting a qualified special education attorney or advocate is strongly recommended.
