The IEP Process in Washington State: A Step-by-Step Guide for Parents

The IEP process in Washington is not a single event — it is a series of procedural steps, each with specific legal timelines and parent rights attached. Missing a deadline or not knowing what to push for at each stage can mean months of delay or services your child doesn't receive. Here is the process from first referral to annual review.

Step 1: The Referral

The process begins when someone suspects a student may have a disability that requires special education services. This can come from a teacher, a parent, a doctor, or another professional. Formally, any person can make a referral.

As a parent, you can make a referral by submitting a written request directly to the special education director at your child's school district. Email creates a time-stamped record. State specifically what educational concerns you have and request an evaluation to determine whether your child is eligible for special education services.

Washington also imposes a "Child Find" obligation on school districts under WAC 392-172A-02040. Districts are legally required to actively seek out students ages 3 to 21 who may have disabilities requiring special education — including students who are passing classes, students who are homeless, and students attending private schools. If your child's school has been aware of persistent academic or behavioral struggles and has taken no action, that may be a Child Find failure you can raise in writing.

Step 2: The District Reviews and Responds (25 School Days)

Once the referral is received, the district has 25 school days to:

• Review existing data about the student
• Consult with the parent
• Issue a Prior Written Notice (PWN) declaring whether they will evaluate or refuse

If the district agrees to evaluate, the PWN will describe the proposed evaluation scope. If the district refuses, the PWN must explain why and what data supports the refusal. If you receive a refusal and disagree with it, you have the right to request mediation or file a due process complaint.

"School days" in Washington means days when students are required to be in attendance. Weekends, holidays, and summer break don't count. If the referral is made in late May, the clock pauses over the summer.

Step 3: Parent Consent for Evaluation

After the district issues a PWN agreeing to evaluate, you must sign consent for evaluation. Once you sign, the 35-school-day evaluation clock begins. Do not sign consent until you understand what the district proposes to evaluate and why — the PWN should describe the areas of assessment.

Consent for evaluation is separate from consent for services. Agreeing to let the district evaluate your child is not the same as agreeing to any resulting IEP.

Step 4: The Evaluation (35 School Days)

The district has 35 school days from the date of your signed consent to complete a comprehensive evaluation. The evaluation must assess the student in all areas of suspected disability — cognitive, academic, behavioral, communicative, adaptive, and any other relevant domain.

A legally compliant evaluation uses multiple measures, not just a single test. It should include standardized assessments, direct observation, teacher and parent input, and review of existing records. If the evaluation is narrow — for instance, only an academic achievement test when the concern includes behavior and social communication — it may be legally insufficient.

After the evaluation is complete, the district schedules an eligibility meeting to share the results and determine whether the student qualifies for special education.

Step 5: Eligibility Determination

To qualify for an IEP in Washington, the student must:

1. Have a disability in one of 13 categories under WAC 392-172A-01035
2. Have that disability adversely affect educational performance
3. Require Specially Designed Instruction (SDI)

A medical diagnosis does not automatically establish eligibility — the district applies its own criteria. If you disagree with the eligibility finding (either the district finds your child ineligible, or qualifies them under the wrong category with insufficient scope), you have the right to request an IEE at public expense. The district has 15 calendar days to either fund the IEE or file due process to defend their evaluation.

Step 6: IEP Development

If the student is found eligible, the IEP team must develop the initial IEP and begin services within 30 calendar days of the eligibility finding. This timeline is frequently overlooked.

The IEP development meeting is where the team builds the document — PLAAFP, annual goals, services and supports, placement, accommodations. You are a required member of this team. The district may bring a draft to the meeting, but the IEP must be developed with your meaningful participation, not just presented to you for signature.

Key elements of a Washington IEP:

• PLAAFP: Strengths-based present levels, with specific data documenting current performance
• Annual goals: Measurable, PLAAFP-connected, with clear criteria and methods for measurement
• Special education and related services: Specified in minutes per week with service type and provider
• LRE determination: Documented rationale for placement
• Supplementary aids and accommodations: Specific to the student's needs
• ESY determination: Whether summer services are needed to prevent significant regression

Step 7: Placement

Placement is determined by the IEP team based on the Least Restrictive Environment (LRE) mandate. The default is the general education classroom with supports. More restrictive settings require documented justification that inclusion with supplementary aids and services cannot produce an appropriate outcome.

The LRE determination is not made by the district unilaterally — it is an IEP team decision, and you are part of that team. If the district is proposing a self-contained classroom or a more restrictive program, request the Prior Written Notice explaining why that placement is the least restrictive appropriate option, and what options were considered and rejected.

Step 8: Annual IEP Review

Every IEP must be reviewed and rewritten at least once per year. The review examines progress toward annual goals, updates the PLAAFP based on current data, revises goals for the coming year, and confirms that services remain appropriate.

You can request a review at any time — you do not have to wait for the annual date if circumstances have changed significantly.

Step 9: Triennial Reevaluation

Every three years, the district must conduct a comprehensive reevaluation to confirm the student continues to meet eligibility criteria and identify any new areas of need. The parent must be notified before the reevaluation and must consent if the district proposes any new testing. The reevaluation is also an opportunity to request that new areas of suspected disability be assessed — submit that request in writing before the evaluation consent is signed.

What to Do at Each Step

At every stage, document everything in writing. Request Prior Written Notices for any district decision. Track evaluation timelines and flag delays. Bring a note-taker or a support person to meetings. Ask for explanations when educational jargon is used.

The Washington IEP & 504 Blueprint includes a timeline cheat sheet for every WAC 392-172A deadline, meeting preparation checklists for each stage, and language for requesting PWNs, disputing evaluations, and challenging placement decisions.
