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 ECEA IEP development rule. Requires the IEP team to develop the IEP within 30 calendar days of eligibility determination. Adds CO-specific: (1) Transition planning begins by age 15 (one year earlier than federal 16), (2) IEP must include Specially Designed Instruction (SDI) descriptions, and (3) Communication Plan required for deaf/hard-of-hearing students.
What this means for you: CO transition begins at AGE 15 — earlier than federal 16. CO IEP must describe SDI in detail, not just goals. CO Communication Plan required for deaf/HOH students (similar to GA's Deaf Child Bill of Rights). CO 30 calendar days from eligibility to IEP.
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.
Colorado PTI founded in 1986 offering free and low-cost services including parent advising, workshops, IEP support, inclusive education guidance, and self-advocacy training. Trained parent advisors available by phone, email, or in person.

In Colorado: 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.. (Context: federal law sets a default of 60 calendar days from parental consent — 34 CFR § 300.301(c) — and allows each state to set its own timeframe. Colorado's rule is the one that applies.)
