Quick Answer: Colorado IEP Timelines
In Colorado, the initial special education evaluation timeline language to verify is 60 calendar days from the administrative unit's receipt of written parental consent to completion of the initial evaluation, including the evaluation report, subject to limited exceptions.. The IEP meeting timeline language to verify is After the evaluation, Colorado requires an eligibility meeting within a reasonable time. If the child needs special education, the IEP meeting must occur within 30 calendar days of that determination, and Colorado also requires the initial IEP to be developed within 90 calendar days of evaluation consent. Initial services require separate parental consent.
Use those dates as a starting point, then verify the current rule on the official state source. You can also review a Colorado IEP for timeline and documentation questions, review the written IEP, or run a Colorado IEP audit.
If You Need the Colorado IEP Timeline Fast
For Colorado, start with the dated written record: referral or request date, consent date, evaluation completion date, eligibility date, IEP meeting date, and Prior Written Notice date. This guide lists the evaluation timeline as 60 calendar days from the administrative unit's receipt of written parental consent to completion of the initial evaluation, including the evaluation report, subject to limited exceptions. The next IEP and implementation checkpoints are: After the evaluation, Colorado requires an eligibility meeting within a reasonable time. If the child needs special education, the IEP meeting must occur within 30 calendar days of that determination, and Colorado also requires the initial IEP to be developed within 90 calendar days of evaluation consent. Initial services require separate parental consent. Verify the current official source before quoting a deadline.
A parent searching this is usually trying to work out whether the school response, evaluation, eligibility meeting, IEP meeting, or written notice is late, missing, or documented too vaguely.
Related questions parents ask
Calm sentence to send
"I am comparing my records with the Colorado timeline. Can you confirm which date the district is using to start the clock, where that date appears in the record, and which rule or exception the team is relying on?"
Use this as a parent-friendly starting point. State rules can change, and exceptions can matter. Before quoting a deadline in a letter or complaint, confirm the exact language on the official Colorado source and consider a qualified local resource for legal advice.

Colorado consent-to-services record
Treat written evaluation consent as the anchor for two Colorado deadlines: 60 calendar days to finish the evaluation and 90 calendar days to develop the initial IEP if the child is eligible. Preserve the later eligibility, initial-services consent, and actual service-start dates as separate events.
Pull these records first
- the parent request or school referral, Prior Written Notice, consent form, and proof of the date the AU received written evaluation consent
- the completed evaluation report and the eligibility-meeting notice and decision
- the initial IEP, separate consent for initial services, and the schedule or service log showing when implementation began
Ask in writing
"What date did the AU receive written evaluation consent, on what dates were the evaluation and eligibility completed, and do the initial IEP and service-start records satisfy both Colorado's 60-day and 90-day checkpoints?"
Before quoting a rule
Colorado's current ECEA Rules define the evaluation clock, the 90-day initial-IEP cap, limited evaluation exceptions, and the 365-day annual-review interval. CDE's current data definitions separately track consent received, evaluation completed, eligibility, IEP finalized, and implementation.

Reviewed 2026-07-17. Confirm exceptions before relying on the timeline.
The 60-calendar-day evaluation rule does not apply when a parent repeatedly fails or refuses to produce the child. A qualifying transfer requires sufficient progress and an agreed completion date. CDE also tracks a written parent-professional extension for certain SLD identification circumstances; ask the AU to identify the exact exception and supporting record.
Colorado deadlines to put on one page
Match each checkpoint to the dated document in your record. These are organizing anchors, not a legal conclusion; exceptions and waivers can change the count.
Evaluation-consent receipt
The referral process is initiated when the parent provides written consent after a school referral or when the AU receives the parent's evaluation request and written consent. Keep proof of the AU's receipt date.
Initial evaluation completed
The initial evaluation must be complete within 60 calendar days from referral initiation. CDE data guidance treats completion as finishing the results, analysis, and evaluation report.
Eligibility determination
After the initial evaluation is completed, a meeting must determine disability and eligibility within a reasonable time. Eligibility and IEP development may occur at the same or different meetings.
Initial IEP developed
For an eligible child, Colorado requires the initial IEP to be developed within 90 calendar days after parental consent to conduct the initial evaluation; the federal 30-day post-eligibility IEP rule also applies.
Initial services and implementation
Evaluation consent is not consent for the initial provision of special education. Keep the initial-services consent and the actual service-start date as separate records.
Build the Timeline From Your Own Documents
A parent usually gets further by bringing a clean record than by arguing from memory. Pull these dates and documents together before you ask the school to explain a deadline.
Referral or written request date
Where to find it
Email, letter, portal message, meeting notes, or the referral form.
Why it matters
Some state clocks begin with referral, while others focus on written consent.
Signed consent date
Where to find it
Evaluation consent form, assessment plan, or parent signature page.
Why it matters
Many evaluation timelines are measured from consent, so keep the signed copy.
Evaluation completion date
Where to find it
Evaluation report cover page, eligibility report, or team meeting notice.
Why it matters
This is the date to compare against the evaluation timeline listed on the guide.
Eligibility and IEP meeting dates
Where to find it
Meeting notice, attendance page, eligibility summary, or IEP signature page.
Why it matters
These dates help you check whether the written IEP followed the eligibility decision.
Prior Written Notice and parent concerns
Where to find it
PWN, meeting notes, parent input page, or follow-up email from the school.
Why it matters
Notices and parent concerns are often where the record shows what was requested, refused, or changed.
What To Check Before You Decide Something Is Late
A date can look wrong because the wrong clock is being used, or because an exception, refusal, transfer, school break, or missing consent date is buried in the record. Check these points before escalating.
Record checks
- Which event starts the clock: referral, written request, signed consent, eligibility decision, or IEP meeting.
- Whether the rule counts calendar days, school days, business days, days in attendance, or another state-specific period.
- Whether the school documented a refusal, delay, extension, transfer, vacation break, student absence, or other exception.
- Whether the IEP, eligibility paperwork, meeting notice, and Prior Written Notice tell the same story.
Red flags to clarify in writing
- The school talks about the timeline verbally but will not identify the written start date.
- The team relies on an intervention or MTSS process without answering the evaluation request in writing.
- A delay, refusal, or service change is not reflected in Prior Written Notice or meeting notes.
- The date in the IEP does not match the email, consent form, evaluation report, or meeting notice.
Colorado Rules and Terms to Verify
Colorado's ECEA Rules use one consent date for both the 60-calendar-day evaluation checkpoint and the 90-calendar-day initial-IEP cap.
Colorado assigns special education responsibility through Administrative Units (AUs), which may be a district, BOCES, multi-district unit, qualifying charter structure, or the State Charter School Institute.
Colorado requires the annual IEP review and placement meeting at least once every 365 days rather than describing the interval only as once per school year.
Official source check
Verify the Colorado rule before you quote it
This guide organizes the parent workflow, but the official state source is the place to confirm current rules, exceptions, and complaint options.
Use the official source first
Open the state education link and look for current special education rules, procedural safeguards, parent rights, and dispute-resolution pages.
Check the exact clock language
Confirm whether the rule says calendar days, school days, business days, referral date, consent date, eligibility date, or IEP implementation date.
Save what you relied on
Write down the page title, link, and date accessed. If a PDF is involved, save the file or note the page number.
Ask for the district's source
If the school says a different rule applies, ask them to identify the state or federal source in writing so you can compare it calmly.

Match the Timeline Question to the Right Record
If the written record still looks unclear, choose the narrowest next step. That keeps the conversation focused on dates, documents, and the source the team is relying on.
Timeline Concerns and Red Flags in Colorado
Deadlines can be missed or documented unclearly. Here's what to watch for and what to ask in writing.
The school missed the evaluation deadline but says 'we're still working on it'
What to say:
Say: 'Based on the timeline I have, this evaluation deadline appears to have passed. I'm requesting written clarification and Prior Written Notice where applicable, and I am reviewing state complaint options.'
How the audit helps:
Our audit checks dates visible in the IEP against the timelines represented in the review and flags issues that may need closer review.
You never received a copy of the IEP or the Prior Written Notice after the meeting
What to say:
Say: 'I'm requesting a copy of the IEP in writing today and asking the team to confirm the timeline for providing it. I'm also documenting that I have not received it yet.'
How the audit helps:
We flag missing or unclear procedural language that appears in the written IEP.
The school scheduled the IEP meeting without asking about your availability
What to say:
Say: 'I need to reschedule to a time when I can fully participate. Please provide alternative dates and document how the team considered parent participation.'
How the audit helps:
We review whether parent concerns and important team decisions are documented clearly in the IEP.
The school says 'we don't have to do that in this state'
What to say:
Say: 'Can you cite the specific state regulation you are relying on? I'd like that in writing so I can compare it with IDEA and state procedural safeguards.'
How the audit helps:
We review the IEP against federal requirements and the state-specific rules represented in the audit.
What to Write When You Need Clarification
The goal is to create a clean written record without sounding like you are already in a fight. These scripts are cautious on purpose.
When a timeline looks late
"I am comparing my records with the timeline I found. Can you confirm which date the district is using to start the clock and where that is documented?"
When the team says the state rule is different
"Can you send me the specific state rule or district procedure you are relying on? I want to make sure I am reading the same source."
When a decision is not in the paperwork
"Please show me where this decision, refusal, or change appears in the IEP or Prior Written Notice so I can keep my records accurate."
When you need a calmer next step
"I am not trying to escalate today. I am trying to get the dates and written record clear so the team can fix anything that is missing."
What To Do Right Now
Create a one-page timeline for Colorado: referral/request date, signed consent date, evaluation completion date, eligibility decision date, IEP meeting date, and the date you received Prior Written Notice.
Start with the administrative unit's documented receipt of written evaluation consent and count calendar days, not school days. Compare that date with the completed evaluation report and ask the unit to identify the exact exception record for any later date.
Compare your eligibility and IEP meeting dates with this listed meeting timeline: After the evaluation, Colorado requires an eligibility meeting within a reasonable time. If the child needs special education, the IEP meeting must occur within 30 calendar days of that determination, and Colorado also requires the initial IEP to be developed within 90 calendar days of evaluation consent. Initial services require separate parental consent.
Open the Colorado Department of Education source and confirm the exact words used for day counts, start dates, and any exceptions that may apply.
Send one calm written question at a time. Ask the school which date they are using, where it appears in the record, and which rule they are relying on.
Do the Written Dates Raise Colorado Timeline Questions?
Timeline questions often begin with dates and notices in the written record. Upload your child's IEP to flag dates or procedural language that may need clarification, then confirm state-specific concerns with a qualified professional.
