The timelines, deadlines, and rights that apply to YOUR child's IEP in Colorado — in plain language, with the actual law attached. Verified citations, no legalese, no paywall on knowledge.
Federal law (IDEA) sets the floor; Colorado sets some of its own clocks. These are the ones parents use most:
60 calendar days from receipt of written parental consent to complete evaluation and hold eligibility determination meeting. Calendar days — summer, breaks, and weekends all count.
Colorado does not specify a separate response timeline beyond the federal requirement. The consent date starts the clock.
90 calendar days from the original consent date to have the initial IEP developed (if found eligible). This means the IEP must be done within 30 days of eligibility if eligibility was determined at day 60.
Written complaint filed with CDE. Must include specific allegations and facts. Copy to school district required. — Colorado Department of Education, Exceptional Student Services Unit. File violation must have occurred within 1 year of filing date. Resolved in 60 calendar days from receipt of complaint.
Resolution session: Within 15 days of due process complaint filing. Hearing decision: 45 days after resolution period ends. Colorado uses Impartial Hearing Officers (IHOs) for due process hearings. IHOs are contracted through CDE..
Tip: every one of these clocks starts with something in writing. Emails count. Phone calls don't.
Colorado's ECEA IEP rule. The initial IEP must be developed within 90 CALENDAR DAYS of the date parental consent was obtained (Rule 4.03(1)(d)(i)) — and the federal rule requiring the IEP meeting within 30 days of eligibility (34 CFR § 300.323(c)) also applies. Colorado-specific: transition planning begins with the first IEP developed when the child is AGE 15 (no later than the end of 9th grade) — earlier than the federal 16 — and the IEP for each child with a hearing disability must include a Communication Plan developed by the IEP team. ECEA rules were amended effective May 12, 2025 (significant-change-of-placement provisions).
What this means for you: CO transition planning starts with the first IEP developed when your child is 15 — earlier than the federal 16. A child with a hearing disability must have a Communication Plan in the IEP, developed by the team. Initial IEP: within 90 calendar days of consent under ECEA Rule 4.03 — and federal law separately requires the IEP meeting within 30 days of eligibility. ECEA rules were amended effective May 12, 2025 (placement-change provisions).
Colorado Exceptional Children Educational Act (ECEA). Establishes FAPE for children with disabilities ages 3-21. CO authorizes 178 Administrative Units (AUs) — districts or BOCES consortia — as the IDEA-responsible entities.
What this means for you: CO uses Administrative Unit (AU) — your district or BOCES (Board of Cooperative Educational Services). CO 60 CALENDAR DAYS evaluation timeline. CO ECEA service categories include Specific Learning Disability with broader PSW criteria than federal. CO Special Education Advisory Committee (SEAC) — public meetings, parent reps.
