Illinois IEP Evaluation Timeline: The 60 School Day Rule Explained

Your written evaluation request is in. The school sent back a consent form, you signed it, and now you're waiting. But how long is too long? When does the district cross the legal line? Illinois has a specific answer that most parents — and some school staff — don't know precisely.

The Illinois Rule: 60 School Days from Consent

Under 23 Illinois Administrative Code §226.110, once a parent provides written consent for an initial special education evaluation, the school district has 60 school days to:

1. Complete all required assessments
2. Hold an eligibility meeting (also called a conference) to determine whether the child qualifies for special education

The 60-day clock starts on the date the district receives your signed consent form. Not when you submitted your initial written request. Not when the school psychologist was assigned. The date they received your signature on the consent to evaluate document.

Illinois uses school days — not calendar days. During a standard school year with approximately 180 days, 60 school days works out to roughly 12 calendar weeks, or about three months. In practice, if you sign consent in late September, the deadline typically falls in January. If you sign in January, the deadline is in April or May.

How to Count School Days Yourself

Don't assume the district is tracking the deadline. Count it yourself.

Get a copy of the district's academic calendar, which should be publicly available on the district website. Starting from the day after the district received your signed consent, count every instructional day that school is in session. Days excluded from the count include:

• Saturday and Sunday
• Federal holidays
• Snow days and other emergency closures
• Winter break, spring break, Thanksgiving break
• Teacher institute days and professional development days when students are not in attendance

Keep a running calendar in your records. When you reach day 60 and have not received an evaluation or been contacted to schedule an eligibility meeting, the deadline has expired.

What to Do If the School Misses the Deadline

First, confirm the deadline in writing. Send an email to the case manager and Special Education Director stating the date you signed consent, your count of school days, and the date by which the evaluation was legally required. Ask for an immediate status update and a specific date for the completed evaluation and eligibility meeting.

This email does two things: it demonstrates that you know the law, and it gives the district one final opportunity to act before you escalate.

If the district does not respond with a concrete timeline within a few school days, or if the evaluation remains incomplete weeks after the deadline, file an ISBE State Complaint. The violation — failure to evaluate within 60 school days of consent — is clear, documentable, and exactly the type of procedural noncompliance ISBE investigates.

ISBE has 60 calendar days to investigate and issue a decision. A finding of noncompliance can require the district to immediately complete the evaluation, schedule the eligibility meeting, and potentially provide compensatory education if the delay caused your child to miss services they were entitled to.

The Common Ways Districts Delay the Clock

Understanding how delays happen helps you catch them before the deadline passes.

Delayed consent forms. Some districts sit on an evaluation request for weeks before sending the consent form. Since the clock starts when you sign — not when you requested — a district that waits three weeks to send the form has effectively extended its timeline by three weeks. If you submitted a written evaluation request and haven't received a consent form within 14 school days, send a follow-up citing 23 IL Admin Code §226.110 and requesting the form immediately.

Claiming MTSS must come first. Some districts tell parents that the child must complete a Multi-Tiered System of Support (MTSS or RTI) process before a special education evaluation can be requested. This is explicitly prohibited under Illinois law. A parent's written request for evaluation must be honored regardless of whether the child is participating in general education interventions. You can acknowledge the MTSS process is ongoing while simultaneously submitting a formal written evaluation request.

Extended evaluation timelines without parent agreement. Some districts claim the evaluation timeline can be extended by mutual agreement and attempt to get parents to informally agree to extensions during phone conversations. An extension to the 60-day timeline requires a formal, written agreement signed by both the parent and the district. A verbal conversation is not a valid extension.

Evaluations that don't cover all areas of suspected disability. The 60-day timeline applies to a comprehensive evaluation, not a limited one. If you requested an evaluation for reading disabilities, autism, and emotional/behavioral issues and the school only tested in one area, they have not completed the required evaluation.

What a Complete Evaluation Must Include

A complete special education evaluation must assess your child in all areas related to the suspected disability. Under IDEA and Part 226, the evaluation must:

• Use a variety of assessment tools and strategies, not a single test
• Include input from parents, not just school observations
• Be conducted by qualified personnel
• Assess the child in their native language or mode of communication
• Cover all areas relevant to the suspected disability, which may include academics, behavior, speech/language, motor skills, social/emotional functioning, health, and adaptive behavior

If the district's evaluation feels narrow — focused only on academics when you raised behavioral and social concerns — request in writing that the evaluation be expanded to cover all areas of suspected disability before you sign the eligibility meeting paperwork.

The Evaluation Refusal: What Happens When the School Says No

A school district can decline an evaluation request. But it cannot simply say no. Under 34 CFR §300.503 and Part 226, a refusal must come with Prior Written Notice that explains why the district believes an evaluation is not warranted, what data it reviewed, and what alternatives it considered.

If the district refuses your evaluation request without providing adequate Prior Written Notice — or if the refusal relies on reasons the law doesn't support (like "we're doing MTSS" or "we don't see a problem in the classroom") — you can file an ISBE complaint or request mediation.

You can also request an Independent Educational Evaluation at public expense if you believe the district's basis for refusal is flawed. In a refusal situation, this is less common but legally available if the district has conducted any prior assessment of your child.

Once the Evaluation Is Complete

After the evaluation is finished, the district must hold an eligibility meeting within the same 60-school-day window. At that meeting, the IEP team — which includes you — reviews the evaluation results and determines whether your child qualifies for special education.

If the team finds your child eligible, an IEP must be developed and implemented within 30 calendar days.

If you disagree with the evaluation's findings or methodology, you have the right to request an Independent Educational Evaluation at public expense. The district must either fund the IEE or file for due process to defend its own evaluation. You do not need to explain your reasons for disagreeing in detail — simply stating that you disagree with the district's evaluation is sufficient to trigger the IEE process.

For parents navigating evaluation delays or refusals, the Illinois IEP & 504 Advocacy Playbook includes the evaluation request letter template, the PWN demand letter, and the ISBE complaint framework — all pre-written with the specific Illinois legal citations that prompt action. Knowing the 60-day rule is the first step. Having the letter ready to send is what enforces it.
