Reviewed by Dr. Elizabeth Long, Ph.D. — Director of Special Education, 32 years in public schools.
In Colorado, the school generally has 60 calendar days from when the school receives your written consent to complete your child's initial special education evaluation (under 1 CCR 301-8, ECEA Rule 4.02(3)(c)).
What this deadline covers. Whether your child is eligible is a decision made by a group: school staff with the right training, and you. The state does not make that decision, so there is no letter from the state to wait for. The school itself must give you the eligibility paperwork free of charge.
Colorado then requires the initial IEP within 90 calendar days of consent; school breaks and summer do not extend the 60-day clock.
Under federal law (20 U.S.C. § 1414(a)(1)(C)) the default is 60 calendar days from the school's receipt of consent, but Colorado's own rule controls where it sets one.
The timeline generally begins when the school receives your signed written consent — write the deadline on your calendar that day so you can tell early and calmly if things slip. Try the deadline calculator →
"Calendar days," "school days," and "business days" differ sharply — school and business days exclude weekends and breaks, so the same number can mean very different real dates. Colorado uses the unit shown above.

Every state has a federally funded Parent Training and Information Center that helps families for free. In Colorado, that's PEAK Parent Center. For the official rules, see Colorado's special education office.
Start factually: "Our evaluation was due on [date] based on Colorado's timeline — can you give me an update?" Get the response in writing, and if it keeps slipping without a plan, it's reasonable to involve the special education director and consider a state complaint. Start by assuming it was a scheduling problem, not bad faith.
State special education rules change and are periodically updated. Confirm the current figure with Colorado's Department of Education or your district before relying on any exact date. This is educational information, not legal advice.
We have not yet read this state’s rule at its source. The dates below come from our own dataset, not from Colorado’s published rule, so we are not standing behind them yet. Compare them with your state’s regulation before you rely on them.
