The IDEA 60-Day Evaluation Timeline (34 CFR §300.301): What Triggers the Clock
A parent signs the school district's consent-for-evaluation form. The intake coordinator says the special-education team will be in touch "soon." Seventy days pass. There is no evaluation report, no draft IEP, no scheduling email. The parent calls and is told the team is "still working on it" or that the timeline starts "when we have an assessor available."
That answer is not what the federal regulation says. Under 34 CFR §300.301(c)(1), the initial evaluation must be conducted within 60 days of receiving parental consent — or within the timeframe the state has established. The clock starts at consent. Not at staffing. Not at the parent's original request letter. And the regulation lists the only exceptions that pause it.
The article below walks through what 34 CFR §300.301(c)(1) actually says, how state variance modifies it, what counts as parental consent under 34 CFR §300.300, the missed-deadline pathway, and the §300.301(d) exceptions.
When the 60-Day Clock Actually Starts (34 CFR §300.301(c)(1))
34 CFR §300.301(c)(1) sets two parallel triggers. Subsection (c)(1)(i) requires the initial evaluation to be conducted within 60 days of receiving parental consent. Subsection (c)(1)(ii) defers to a state-established timeframe if one exists. The starting event in both branches is the same: the date the signed consent-for-evaluation reaches the district.
The original referral letter does not start the clock. The referral obligates the district to respond — either by proposing an evaluation (which requires obtaining consent) or refusing one (which requires Prior Written Notice). Only the signed consent-for-evaluation, returned to the district, starts the 60-day window.
- The trigger is consent, not request. The 60 days run from the date the district receives the signed consent-for-evaluation form, per 34 CFR §300.301(c)(1)(i).
- The trigger is consent, not staffing. Assessor availability and contract-evaluator turnaround are not exceptions in the regulation.
- The 60 days are calendar days unless the state has substituted school days in its own timeline.
- "Conducted" generally means completion of testing and issuance of the evaluation report. Some states extend the window to include the eligibility determination meeting.
For parents whose evaluation request was refused before consent was ever discussed, the procedural path is different — see Prior Written Notice when school refuses to evaluate.
State Variance: 30, 45, 60, 90 Days
34 CFR §300.301(c)(1)(ii) defers to state-established timeframes where they exist. State timelines vary — some shorten the window to 45 calendar days, some operate on school days, some carve out school-break exclusions. Concrete examples (parents should verify against the current state regulation):
- California — assessment plan within 15 calendar days of referral; evaluation and IEP meeting within 60 calendar days of signed consent (excluding school breaks longer than 5 days). California Education Code §56043 and §56344.
- Texas — Full and Individual Initial Evaluation report within 45 school days of written consent. 19 Texas Administrative Code §89.1011.
- Florida — up to 60 school days from receipt of written parental consent. Florida State Board of Education Rule 6A-6.0331.
- New York — initial evaluation within 60 calendar days of receipt of parental consent. 8 NYCRR §200.4(b).
The federal floor is 60 calendar days from receipt of consent; state regulations may shorten the window, substitute school days, or carve out school-break exclusions. The federally funded parent training and information center for the parent's state — indexed at parentcenterhub.org — is the lowest-friction starting point for verifying current state timelines.
What Counts as Parental Consent (34 CFR §300.300)
34 CFR §300.300(a) requires the district to obtain informed written consent before conducting the initial evaluation. The companion definition at 34 CFR §300.9 sets the standard: the parent has been fully informed in the parent's native language or other mode of communication, agrees in writing, and understands the consent is voluntary and may be revoked at any time (revocation is not retroactive).
For the 60-day clock, the operational definition is narrower: a signed and dated consent-for-evaluation form, returned to the district, in a language the parent understands. Verbal consent does not start the clock. The cleanest record is a signed paper or signed PDF returned by a method that produces proof of delivery — certified mail, hand delivery with a stamped receipt, or email with an acknowledgement from the special-education office. Documenting the date forecloses the most common district defense ("we did not receive consent until later").
When the Deadline Is Missed
If the district does not complete the evaluation within the federal 60-day floor (or the shorter state-established timeframe), the parent has two formal IDEA pathways: state complaint and due process. They are not mutually exclusive, and neither requires an attorney to initiate.
State complaint under 34 CFR §300.151–153. Any individual or organization may file a written complaint with the state educational agency alleging an IDEA violation. The state must resolve the complaint within 60 days of receipt (with limited extensions). Missed evaluation timelines are among the most-commonly-substantiated complaint categories. The filing requirements at §300.153 specify the elements: statement of the alleged violation, facts, signature, contact information, and (for child-specific complaints) the child's name, address, school, and proposed resolution.
Due process complaint under 34 CFR §300.507. A parent may file a due process complaint on any matter relating to the identification, evaluation, or educational placement of a child with a disability. The complaint triggers a resolution session within 15 days, and (if unresolved) a hearing before an impartial hearing officer. Procedural requirements are at 34 CFR §300.508. Due process is more adversarial than state complaint and is the right pathway when the missed timeline is one symptom of a broader denial of FAPE.
Parents who suspect the district's evaluation, when it arrives, will be incomplete or biased should also be aware of the Independent Educational Evaluation request pathway under 34 CFR §300.502.
Exceptions to the 60-Day Rule (34 CFR §300.301(d))
34 CFR §300.301(d) lists the only two exceptions to the 60-day timeline. The exceptions are narrow and the burden of demonstrating that they apply rests with the district.
- Parent fails to produce the child for evaluation — under §300.301(d)(1), the timeframe does not apply if the parent repeatedly fails or refuses to produce the child for the evaluation. Not a slow-scheduling exception; it requires a documented pattern of parent unavailability after the district has scheduled and attempted the evaluation.
- Child enrolls in another district mid-evaluation — under §300.301(d)(2), the timeframe does not apply if the child enrolls in another public agency after the timeframe has begun but before eligibility has been determined, and only if the subsequent agency is making sufficient progress to ensure prompt completion and the parent and subsequent agency agree to a specific completion date.
Notably absent from §300.301(d): assessor unavailability, staffing shortages, school breaks, snow days, and contract-evaluator backlogs. Districts that invoke an exception not listed in §300.301(d) are operating outside the federal floor.
For parents weighing whether to pursue an IEP evaluation at all versus a 504 plan path, the threshold-eligibility question is separate from the timeline — see 504 vs IEP federal law differences.
Frequently Asked Questions
Does the 60-day timeline start when I send the evaluation request letter?
No. Under 34 CFR §300.301(c)(1)(i), the clock starts when the district receives signed parental consent for evaluation — not when the request letter is sent. The request letter triggers the district's obligation to respond (by proposing an evaluation and seeking consent, or refusing and issuing Prior Written Notice). Only the returned, signed consent form starts the 60-day clock.
Are the 60 days calendar days or school days?
Under federal 34 CFR §300.301(c)(1)(i), the 60 days are calendar days. State regulations may substitute school days — Texas uses 45 school days under 19 TAC §89.1011, Florida uses 60 school days under Rule 6A-6.0331. Parents should check the current state special-education regulation.
What if my state has a shorter timeline than 60 days?
The shorter state timeline controls. 34 CFR §300.301(c)(1)(ii) defers to the state-established timeframe when one exists, and the federal 60 days is a floor — states may shorten the window but may not lengthen it past 60 calendar days from receipt of consent.
The school missed the deadline. What do I do first?
The first step is a written follow-up that documents the consent date, the elapsed time, and the federal citation (34 CFR §300.301(c)(1)). The follow-up creates the paper record any later state complaint will cite. If the district does not complete the evaluation within a reasonable additional period, a state complaint under 34 CFR §300.151–153 is the next step. Due process under 34 CFR §300.507 is the heavier path, generally reserved for cases where the missed timeline is one symptom of a broader denial of FAPE.
Can the district pause the 60-day clock for school breaks or staff shortages?
Federal 34 CFR §300.301(d) lists only two exceptions: parent repeatedly fails to produce the child, and child enrolls in another district mid-evaluation. School breaks, snow days, assessor unavailability, and contract-evaluator backlogs are not federal exceptions. Some state regulations carve out school breaks of a defined length, but the federal regulation does not.
What counts as parental consent for IDEA evaluation purposes?
Under 34 CFR §300.300(a) and the consent definition at 34 CFR §300.9, consent is informed, in writing, in the parent's native language, and voluntary. For the operational 60-day clock, the cleanest record is a signed and dated consent-for-evaluation form returned by a method that produces proof of delivery — certified mail, hand delivery with stamped receipt, or email with acknowledgement. Verbal consent does not start the clock.
Does the 60-day timeline cover the eligibility determination meeting?
Federal 34 CFR §300.301(c)(1) requires the initial evaluation to be "conducted" within 60 days. Most state implementations interpret this as completion of testing and issuance of the evaluation report; some state regulations extend the window to include the eligibility determination meeting itself, governed separately by 34 CFR §300.306. Parents should check the state regulation for the specific scope.
