How to Request a Special Education Evaluation in Washington State

You've watched your child struggle for months — maybe years — and informal interventions haven't helped. You want to know whether they qualify for special education services. Here is exactly how to start the process in Washington State, what the law requires, and what to do when the district pushes back.

Start With a Written Request

The most important thing to know about requesting a special education evaluation in Washington: put it in writing. A verbal conversation with a teacher or counselor is not a referral under WAC 392-172A. It has no legal effect and starts no clock.

Send a written request — email is fine, it creates a timestamp — directly to the special education director at your child's school district. Your letter does not need to be elaborate. State that you suspect your child has a disability that is affecting their educational performance, that you are requesting an evaluation to determine eligibility for special education services under IDEA and WAC 392-172A, and that you are requesting a response within the timelines required by state law.

Keep a copy of everything you send. Note the date you sent it.

The 25-School-Day Response Deadline

Once the district receives your written request, the clock starts. The district has 25 school days to:

• Review existing data about your child
• Consult with you
• Issue a Prior Written Notice (PWN) either agreeing to evaluate or formally refusing

"School days" in Washington is defined strictly — days when students are required to be in attendance. Weekends, holidays, and summer break don't count. A request submitted in late May may pause over summer and resume in September.

If the district agrees to evaluate, the PWN will describe the proposed evaluation areas and methods. If the district refuses, the PWN must explain the basis for refusal and what data supported that decision. A verbal "no" without a PWN is not legally valid.

What Happens After You Sign Consent

Once you receive a PWN agreeing to evaluate, the district will ask you to sign consent for the evaluation. Do not sign until you understand what areas will be assessed. The PWN should describe the scope — cognitive testing, academic achievement, behavioral assessment, speech-language evaluation, etc. If the scope seems narrow relative to your concerns, ask the district to expand it before you sign.

Once you sign, the district has 35 school days to complete the evaluation. This is a hard deadline under WAC 392-172A. If the district misses it, that is a procedural violation you can raise with OSPI.

The only way to extend the 35-day window is if both you and the district agree in writing — for example, if the team is waiting for results from an outside medical evaluation that would inform the school's assessment.

What the Evaluation Must Cover

The evaluation must assess the student in every area of suspected disability, not just the area most convenient for the district. For a student referred because of academic struggles, the evaluation might include:

• Cognitive testing (intelligence quotient, processing speed, working memory)
• Academic achievement testing in reading, writing, and math
• Speech-language evaluation if communication is a concern
• Behavioral assessment including teacher and parent rating scales if behavioral or emotional functioning is a concern
• Adaptive behavior assessment if daily living skills are relevant

If the referral concerns include social-emotional functioning, executive function, or sensory processing, those areas must be included in the scope. A narrow evaluation that misses areas of suspected disability can be challenged.

The evaluation must use multiple measures — not just a single test. It must include input from you as the parent, teacher observations, and a review of existing records. Results from medical evaluations or private assessments you provide must also be considered.

What Happens If the District Refuses to Evaluate

If the district issues a PWN refusing to evaluate, you have several options:

Request the basis in writing. The PWN must explain specifically why the district is refusing. Common reasons include "existing data does not suggest a disability" or "current general education interventions are sufficient." Read the reasoning carefully — sometimes it is based on incomplete information or a mischaracterization of your child's performance.

Provide additional information. If you have clinical records, teacher observations, private evaluation results, or other documentation the district may not have reviewed, submit it and request that the district reconsider.

Request mediation. Washington offers free, voluntary mediation through OSPI to resolve disputes about evaluation decisions.

File a due process complaint. You can challenge the refusal through a due process hearing before the Washington Office of Administrative Hearings.

File an OSPI Community Complaint. If you believe the refusal is a procedural violation — for instance, the district is refusing to evaluate despite clear observable indicators of disability, violating their Child Find obligation — you can file a complaint directly with OSPI.

Disagreeing With the Results

If the evaluation is completed and you disagree with the findings — either the child was found ineligible, the eligibility category is wrong, or the evaluation failed to assess areas that needed assessment — you have the right to request an Independent Educational Evaluation (IEE) at public expense.

Notify the district in writing that you disagree with their evaluation. The district then has 15 calendar days to either fund the IEE or file a due process complaint to defend their evaluation.

Washington private neuropsychological evaluations range from approximately $700 at university training clinics to $1,750 to several thousand dollars for comprehensive private evaluations. When the district pays for the IEE, they may impose cost caps and qualification criteria — request those criteria in writing so your chosen evaluator meets them.

Initial Evaluation vs. Reevaluation

If your child already has an IEP and you believe their needs have changed significantly — new diagnosis, lack of progress suggesting the current goals aren't addressing the right areas, significant behavioral shifts — you can request a reevaluation outside the standard three-year cycle. The same written request process applies. The district must respond with a PWN agreeing or refusing within the same 25-school-day timeline.

Washington's Child Find Obligation

If your child's school has been aware of significant academic or behavioral struggles for an extended period and has taken no action to refer for evaluation, that may constitute a violation of the district's Child Find obligation under WAC 392-172A-02040. Districts are required to proactively locate and identify children who may need special education — not wait for a parent to demand an evaluation.

Document the history: teacher communications noting concerns, homework records, report cards, nursing records, behavior incident logs. That documentation supports a Child Find violation complaint to OSPI if the district has been slow to act despite clear indicators.

The Washington IEP & 504 Blueprint includes the evaluation request letter template, the IEE request process, and the OSPI complaint framework for Child Find violations and refused evaluations.
