Montana Special Education Evaluation Timeline: The 60-Day Rule Explained

One of the most commonly violated rules in Montana special education is also one of the most clearly defined: the district has exactly 60 calendar days to complete an initial comprehensive evaluation once you provide written consent. Not 60 school days. Not 60 business days. Sixty calendar days from the date you sign the consent form.

When that deadline is missed, it is not a minor administrative oversight — it is a procedural violation that OPI takes seriously and that you have the right to act on immediately.

The Clock and How It Starts

Montana's 60-calendar-day evaluation timeline is codified in ARM 10.16.3321 and mirrors the federal requirement under 34 CFR 300.301. The timeline governs initial evaluations — the first comprehensive evaluation conducted to determine whether your child is eligible for special education.

The clock starts the day you sign and return written consent to evaluate. Not the day you submitted the written request. Not the day the district prepared the evaluation plan. Not the day the district mailed the consent form. The day you sign and return it.

This distinction matters because districts sometimes create a gap between when a parent requests an evaluation and when they provide consent. If you submit a written evaluation request but the district takes two weeks to prepare and send a formal consent form, those two weeks are not counted in the 60 days. The 60 days begins when you return the signed consent — and no earlier.

Strategic approach: Submit your written evaluation request and a signed consent form simultaneously in the same communication. Write at the bottom of your evaluation request letter: "I consent to the proposed evaluation as described in this letter." Then follow up when the district sends its formal consent form by signing and returning it the same day, noting the date of your original submission.

This eliminates the gap between request and consent that districts sometimes use to delay the start of the timeline.

What Must Be Completed Within 60 Days

Within the 60-calendar-day window, the district must:

• Administer all assessments required for a comprehensive evaluation
• Review existing data and gather input from parents and teachers
• Complete the written evaluation report
• Provide the evaluation report to parents
• Hold an eligibility determination meeting

If any of these steps is incomplete on day 61, the timeline has been violated. Receiving the report on day 60 is fine; holding the eligibility meeting on day 65 while the report was delivered on day 60 may still be a timeline issue if the report was not provided with sufficient lead time for you to review it meaningfully.

Limited Exceptions to the 60-Day Rule

Montana recognizes two exceptions to the 60-calendar-day requirement:

1. The parent repeatedly fails to make the child available for assessment. If the district has made good-faith efforts to schedule required assessments and the parent has repeatedly declined or failed to bring the child, the timeline may be extended. This exception does not apply when scheduling conflicts are on the district's side.

2. The child enrolls in a new district while the initial evaluation is pending. If your child moves to a new district after the evaluation has begun but before it is complete, the new district has the remaining days to complete the evaluation, provided it is making sufficient progress and the parent agrees to a specific timeline.

These exceptions are narrow. Geographic challenges, cooperative staff availability, specialist travel schedules, and district workload are not valid exceptions. Montana's small rural districts and their cooperative partners must comply with the 60-day timeline regardless of staffing constraints.

How to Know If the Timeline Has Been Missed

Keep a copy of every document related to the evaluation request. Date-stamp everything — your initial written request, the district's response, the consent form you received, and the date you signed and returned it.

If you reach day 55 or 60 without receiving an evaluation report or a meeting notice, contact the special education director in writing: "I signed and returned the evaluation consent form on [date]. The 60-calendar-day evaluation timeline under ARM 10.16.3321 expires on [date]. Please provide an update on the status of the evaluation and confirm the report and eligibility meeting will be completed by that date."

This letter creates a record that you were tracking the timeline and that the district was on notice.

What to Do When the 60-Day Timeline Is Missed

A missed evaluation timeline is one of the most straightforward violations to document and report through an OPI state complaint. The evidence is simple: your signed consent date and the date the evaluation was completed or the report was provided. If the gap exceeds 60 calendar days, the violation is documentable from the district's own records.

File a state complaint under ARM 10.16.3662 with the OPI Superintendent of Public Instruction. Your complaint should include:

• Your child's name, grade, and school
• The date you provided signed consent
• The date the evaluation was completed or the report was provided (if it was late), or a statement that the evaluation has not been completed (if still pending)
• The number of calendar days elapsed
• A proposed resolution (completion of the evaluation immediately, compensatory services for the delay, a corrective action plan)

OPI must complete its investigation within 60 days and can mandate corrective action including completion of the evaluation, IEP development, and compensatory services if appropriate.

Reevaluation Timelines

The same 60-calendar-day rule applies to reevaluations when new assessments are required. The clock starts when you sign consent for the reevaluation assessments. If the district determines during the existing data review that no new assessments are needed and you agree, the reevaluation can be completed without new testing — and the timeline does not apply in the same way.

However, Montana requires written parental consent for reevaluations, unlike the federal baseline. If the district proceeds with new assessment components without obtaining your written consent, that is a separate procedural violation regardless of timeline.

Evaluation Timeline and the IEP Evaluation Timeline Are the Same

Search results for "montana iep evaluation timeline" typically reflect the same 60-calendar-day rule. Whether you're looking at the initial eligibility evaluation or the reevaluation that precedes an IEP update, the timeline framework is governed by ARM 10.16.3321 and the same calendar-day counting rules apply.

The only meaningful distinction is that the initial evaluation leads to an eligibility determination, while a reevaluation leads to a determination of continued eligibility and an IEP update. In both cases, once you sign consent for new assessments, the clock runs for 60 calendar days.

If you need a dated, written evaluation request letter that includes simultaneous signed consent — formatted to start the clock immediately and close the gap that districts sometimes exploit — the Montana IEP & 504 Advocacy Playbook includes exactly that template.
