How long does a school in Colorado have to complete an IEP evaluation?
Colorado starts the evaluation clock at the written parental consent that opens a special education referral. The state rule allows 60 calendar days from that point to complete the initial evaluation, with the meeting that decides eligibility held within a reasonable time after the evaluation is finished. A second state clock runs off the same signature: the initial IEP for a child found eligible is developed within 90 calendar days of the date consent was obtained. Colorado delivers special education through administrative units, so the agency responsible may be a school district, a board of cooperative services, a charter school network or the state Charter School Institute. A family that disagrees has three routes in three different sets of hands: a written state complaint decided by a state complaints officer at the Colorado Department of Education, free mediation with an independent contract mediator, or a due process complaint heard by an administrative law judge at the Office of Administrative Courts.
The evaluation timeline in Colorado
| Initial evaluation window | 60 calendar days |
|---|---|
| The clock starts at | parental consent to evaluate |
| Against the federal rule | The federal default, unchanged |
IDEA sets a default of 60 calendar days from parental consent for an initial evaluation (34 CFR 300.301(c)(1)). Colorado keeps that default rather than setting a timeframe of its own.
Colorado follows the federal 60 calendar day default for completing the initial evaluation, counted from the written parental consent that starts the special education referral. The meeting that decides eligibility is held within a reasonable time after the evaluation is complete rather than on a day count of its own. For a child found eligible, the initial IEP is developed within 90 calendar days of that same consent date.

The same window sits beside all fifty-one jurisdictions on the evaluation timelines by state table, which explains where the federal deadline comes from. To pull one state's window on its own, the evaluation deadline checker returns that single result.
Reevaluation and IEP review cadence in Colorado
Colorado leaves the reevaluation cycle to the federal rule. The state rule sends reevaluations straight to 34 CFR 300.303, so one happens at least every three years unless the parent and the administrative unit agree it is unnecessary. It happens no more than once a year unless both agree otherwise. The 60 calendar day clock in Colorado covers an initial evaluation, so a reevaluation carries no separate state completion deadline of its own. Two things do read differently here. Colorado counts the annual review in days rather than in years: meetings to review and revise the IEP and to determine placement are initiated and conducted at least once every 365 days, where the federal rule asks for a review not less than annually. Colorado also closes one federal shortcut. The special education director or designee who knows what the administrative unit can provide and has authority to commit those resources is a required member of the team. The federal excusal provision at 34 CFR 300.321(e) does not apply to that member, so that seat stays filled even where the parent would agree to excuse it.

If you disagree in Colorado
IDEA gives families in every state the same three routes when a disagreement with the school does not resolve at the team table. What changes at the state line is who administers each route, how long you have to file and the local detail below.
The state complaint
Handled by Dispute Resolution, Office of Special Education, Colorado Department of Education. Time limit to file: One year before the filing date, counted from the day the department receives the complaint rather than the postmark date.
A state complaint is a written signed statement that a public agency is not following the federal act or Colorado's own Exceptional Children's Educational Act. Any individual or organization can file one. Colorado still takes it on paper: the complaint goes by mail or hand delivery to the department's dispute resolution office in Denver, with a complete copy going to the special education director of the school district, board of cooperative services or state operated program at the same time. The department does not accept state complaints by email or fax, though its published procedures say a secure electronic option is being built. The department notifies both sides in writing within 10 calendar days of receiving a complaint whether it is accepted for investigation, with a state complaints officer making that call. The public agency may file a response within 15 calendar days of that notice. An allegation it does not answer may be deemed admitted. The person who filed then has 10 calendar days to reply in writing. A written decision with findings of fact and conclusions of law follows within 60 calendar days of a properly filed complaint unless the department extends that clock by written order for exceptional circumstances or for mediation. Remedies can reach compensatory services or reimbursement. Attorney fees sit outside the department's authority. The decision is final under the state rule with no appeal, though the same issues can go to a due process complaint where the party has that right. Restraint and seclusion allegations reach the same desk under separate rules with the same one year window, where the state complaints officer runs the case through the federal complaint process when it also alleges a federal violation.

Mediation
Mediation runs through the department's dispute resolution office at no cost to either side. A parent or a special education director can ask for it by phoning the alternative dispute resolution coordinator or sending the request form. Both sides have to agree before it starts, so the coordinator contacts the other party first. Mediators are independent contractors rather than employees of the department or of any school district, assigned on a rotational impartial basis, trained in mediation as well as knowledgeable about special education law. The assigned mediator contacts both parties within 2 business days. Mediation is typically completed within 30 calendar days of the request. Either side can ask for it at any point, including while a state complaint is being investigated or after a due process complaint is filed, where it can take the place of the resolution meeting if both agree. Where a state complaint is already running, the parties can agree to mediate. The department can then extend the 60 day decision clock by written order. Colorado funds a second service alongside mediation: special education facilitation, where a neutral facilitator sits in on an IEP meeting to keep the team on track. That one is a step before a dispute rather than a way to resolve a filed one.

A due process hearing
Time limit to file: Two years from the date the parent or the public agency knew or should have known about the alleged violation.
Colorado separates filing from deciding. The complaint goes by fax, mail or hand delivery to the department as well as to the special education director of the school district, board of cooperative services or state operated program, with no email filing at present. Within two business days of receiving it the department notifies the Office of Administrative Courts, Colorado's centralized administrative court created in the department of personnel, which assigns an administrative law judge. The responding party files a written response within 10 days. A resolution meeting comes within 15 days of filing unless both sides waive it in writing or agree to mediate instead, inside a 30 day resolution period. The court schedules a prehearing conference within the first 30 days. Unless a party asks for an extension the decision is issued within 75 days of filing, which is the 30 day resolution period plus the 45 days for the hearing. The judge's decision ends the administrative stage because Colorado runs no second level of review. A party has 90 days from the date of the decision to bring a civil action in state or federal court. Discipline cases move faster: the resolution meeting within 7 days, the hearing within 20 school days, the decision within 10 school days, none of it extendable. One Colorado provision has no federal counterpart. Under a 2023 state law a parent who prevailed in a state complaint and then faces a due process complaint from the administrative unit or state operated program on the same issues can contact the Transformative Justice Project of Colorado for an attorney appointed from a rotating list at no cost to a qualifying parent, paid from $20,000 a year the department provides. That section is repealed effective July 1 2029.

Who to contact in Colorado
- The state special education office. Office of Special Education, Exceptional Student Services Unit, Colorado Department of Education. This is the office that answers questions about Colorado rules and receives a state complaint.
- Your rights in writing. Procedural Safeguards Notice: A Guide to Parent Rights in Special Education, Colorado Department of Education Exceptional Student Services Unit, April 2024 edition. Every district hands parents this notice at least once a year (34 CFR 300.504). It is the plain summary of what you can ask for at each step.
- Parent training and information center. PEAK Parent Center. A parent center is free and federally funded under IDEA. Staff there talk families through the process in their own state at no cost.
- The state rules themselves. Exceptional Children's Educational Act, article 20 of title 22 of the Colorado Revised Statutes (C.R.S. 22-20-101 et seq.), with the State Board of Education rules at 1 CCR 301-8, whose own statement of basis and purpose at Rule 1.00 names C.R.S. 22-20-101 et seq. as the act it implements and C.R.S. 22-20-104 as the rulemaking authority; gifted education rules at 1 CCR 301-8, section 12.00. Article 20 of title 22 carries the short title Exceptional Children's Educational Act, the state law that sits under special education in Colorado. Section 22-20-104 gives the State Board of Education its rulemaking power, which is where the Rules for the Administration of the Exceptional Children's Educational Act at 1 CCR 301-8 come from. Those rules hold the deadlines a family meets in practice: the 60 calendar day initial evaluation, the 90 calendar day initial IEP, the 365 day review cycle, the three dispute routes. The same rule chapter also carries Colorado's gifted education rules at section 12.00, so one state act and one chapter of rules cover both special education and gifted programming.
Child Find in Colorado
Colorado runs child find through administrative units for ages 3 to 21, with each unit naming one person responsible for it. The rules ask for strategies aimed at children 3 through 5, children in school, children who have left school, plus a systematic procedure for considering young people ages 17 to 21 who are out of school and may have a disability. Screening follow up ties into the vision and hearing screening Colorado schools run in kindergarten and grades 1, 2, 3, 5, 7 and 9. Two Colorado structures matter for younger children. Birth to age three sits with Early Intervention Colorado at the Colorado Department of Early Childhood under Part C of the federal act, so a family crosses departments at the third birthday. For preschool, the May 2025 rule amendments wrote the state's early childhood programs into the referral chain: a Department of Early Childhood program that learns something about a preschooler follows the child find identification and referral procedures the education department sets, while the administrative unit stays responsible for the initial evaluation itself.
