Parent Rights in Autism Evaluation: What the School Must Tell You

You asked the school to evaluate your child for autism. Maybe they agreed quickly, or maybe you've been waiting months with no answer. Either way, you have specific legal rights throughout this process — and the school has specific legal obligations — regardless of how cooperative or uncooperative the team has been.

The Right to Request an Evaluation

In the US, a parent can request an initial evaluation for special education services under IDEA. Put the request in writing and send it to the school principal or director of special education. IDEA does not set a nationwide 15-school-day deadline for answering an initial request; any separate response deadline depends on state law. The federal evaluation timeline starts after parental consent.

If the school refuses to initiate an evaluation, IDEA requires it to provide Prior Written Notice explaining the refusal. Ask for that notice in writing if the school only gives you a verbal answer.

Prior Written Notice

Prior Written Notice is required when the school proposes or refuses to initiate or change your child's identification, evaluation, educational placement, or the provision of a free appropriate public education (FAPE).

PWN must describe the proposed or refused action and why, list the evaluations, assessments, records, or reports used, explain other options considered and rejected, identify relevant factors, and tell you where to get help understanding IDEA's safeguards.

If the school decides not to evaluate, the PWN must explain why and describe the information and options it considered. Good grades alone do not resolve whether a child has educational needs; functional, social-emotional, behavioral, and communication needs may also be relevant.

Consent and Timelines

The school cannot evaluate your child without your written consent. Consent to evaluate is not consent to placement — agreeing to an evaluation does not automatically enroll your child in special education.

Once you provide consent, IDEA generally requires the initial evaluation within 60 days, unless your state has established a different timeframe. The school must complete a comprehensive evaluation across all areas of suspected disability within that window. If the school suspects autism, the evaluation should consider social communication, restricted and repetitive behaviors, adaptive functioning, and educational impact — not rely on a single screener.

What "Comprehensive" Means

Under IDEA, evaluations must assess the child in all areas related to the suspected disability, use a variety of assessment tools and strategies, not use any single measure as the sole criterion for eligibility, and be technically sound and administered by trained personnel.

For autism specifically, IDEA does not prescribe one assessment battery. The evaluation must cover every suspected area, use a variety of tools, and not rely on a single measure. If the team has not assessed an area where you suspect a need, ask for additional evaluation in that area.

The Right to an Independent Evaluation

If you disagree with the school's evaluation — because it was too narrow, missed key domains, or reached conclusions that contradict what you observe at home — you have the right to request an Independent Educational Evaluation (IEE) at public expense.

The school must either agree to fund the IEE or file for a due process hearing to defend its own evaluation as appropriate. What it cannot do is simply refuse. The school must consider results of an IEE obtained at public expense, or an evaluation obtained privately and shared with the school, if it meets agency criteria, in decisions about providing FAPE.

UK, Canada, and Australia

UK (England): Parents can request an EHC needs assessment from the Local Authority. The LA must tell parents within six weeks whether it will assess. Parents can submit their own evidence, including private assessments; the report can inform the decision but does not guarantee an EHCP.

Canada (Ontario): Parents can request an IPRC review and submit private assessments for the committee's consideration. The IPRC determines school identification under Ontario's provincial criteria.

Australia: Under the Disability Standards for Education 2005, schools provide reasonable adjustments for students with disability. Parents can provide assessment evidence about functional impact; NCCD adjustment levels and NDIS access involve different processes, and a diagnostic label alone does not establish NDIS access.

When the School Stalls

If the school hasn't responded to your evaluation request, follow up in writing and check your state's response deadline, referencing your original request date. If the school has evaluated but left out suspected areas, put your concerns in writing and request additional assessment or an IEE.

Understanding what each assessment tool measures and what the scores mean puts you in a stronger position at every stage. The Autism Evaluation Report Decoder covers ADOS-2, SRS-2, ASRS, CARS-2, ADI-R, and every supporting measure, so you can identify what the evaluation captured — and what it missed.
