MARSE 2024 Updates: What Michigan IEP Parents Need to Know About the New Rules

Michigan's Administrative Rules for Special Education (MARSE) underwent significant updates in 2024. If you're still operating with knowledge from an older guide, a workshop from a few years ago, or advice you picked up from a national resource, you may be missing leverage that only applies to Michigan families — and only under the updated rules.

Why MARSE Updates Matter for Parents

MARSE is the state-level rulebook that governs every public school and charter school in Michigan. While federal IDEA sets the floor, MARSE sets Michigan's higher standards — different timelines, specific class size limits, and more detailed eligibility definitions. When MARSE changes, so do your rights.

The 2024 updates are not cosmetic. Several of the rule changes directly affect what districts are required to do in IEP meetings, who must be on the IEP team, how autism eligibility is determined, and how many students can be placed in certain special education classrooms.

Rule 340.1705: IEP Team Member Requirements

MARSE Rule 340.1705 governs who must be present at an IEP meeting. The core federal requirement — parents, general education teacher, special education teacher or provider, district representative, someone to interpret evaluation data — hasn't changed. But the 2024 updates clarified documentation requirements and the process for excusing team members.

Under the updated rule, when a team member whose area is being discussed is excused from the meeting, the parent must provide prior written consent to the excusal, and the excused member must submit written input before the meeting that is available to the rest of the team.

This is significant for parents because schools sometimes excuse key team members (like the speech pathologist) without proper process, then use the absence to justify tabling service decisions. Under the updated Rule 340.1705, if you weren't asked to consent in writing to an excusal and that person didn't provide written input, the meeting may not have been procedurally compliant.

What to do: Before any IEP meeting, confirm in writing who will be attending. If a key team member is being excused, ask to see their written input and confirm you provided written consent. If neither happened, note the procedural gap and raise it if the meeting outcome is unfavorable.

Rule 340.1721e: Extended School Year (ESY) Documentation

The updated Rule 340.1721e strengthened the requirement that IEP teams explicitly consider and document ESY at every annual review. This isn't just a checkbox — the update requires that the IEP document reflect the team's actual analysis of the student's regression/recoupment history, the nature and severity of the disability, and whether the student is at a critical learning stage.

Under the new language, a bare statement that "ESY was considered and not recommended" without supporting data is potentially insufficient. If your child's IEP says ESY was discussed but the form is blank under the justification section, that's a documentation gap you can challenge.

This matters especially for parents whose children regress significantly over summer breaks. Request the specific data the team used to determine ESY wasn't warranted — if they can't produce it, they may not have conducted the required individualized analysis.

Rule 47: Class Size Limits for Specific Learning Disability Classrooms

This is the rule most Michigan parents have never heard of, and it's one of the most immediately useful pieces of leverage available.

Under updated Rule 47 (formally part of MARSE's caseload provisions), programs serving students with Specific Learning Disabilities (SLD) have strict staffing caps:

• No more than 10 students in a classroom program for SLD at any one time
• Caseloads for SLD resource room teachers cannot exceed 15 students

These aren't suggestions. They're legal maximums. If your child with a Specific Learning Disability (which includes dyslexia, dyscalculia, and processing disorders) is in a resource room with 12 or 14 other students, the district is in violation.

How to use this: Ask the special education teacher or director directly — in writing — how many students are currently enrolled in your child's SLD classroom or assigned to their special education teacher's caseload. If the numbers exceed 10 (classroom) or 15 (caseload), you have grounds for a State Complaint with the MDE Office of Special Education. You can also raise it in the next IEP meeting as a concern about FAPE — an overcrowded SLD classroom isn't delivering the individualized instruction the IEP requires.

The Michigan IEP & 504 Blueprint includes the exact language to use when invoking Rule 47 in an IEP meeting and how to structure a State Complaint if the district is over the cap.

Rule 340.1715: Autism Eligibility Criteria

MARSE Rule 340.1715 governs eligibility for the Autism Spectrum Disorder (ASD) category. The 2024 updates aligned the MARSE eligibility criteria more closely with the DSM-5 diagnostic framework, while maintaining Michigan-specific assessment requirements.

Under the updated rule, eligibility for ASD under MARSE requires documentation of impairments in social communication and interaction, and restricted, repetitive patterns of behavior or interests — consistent with DSM-5 criteria. However, MARSE also requires that the MET demonstrate the ASD characteristics adversely affect the student's educational performance.

The key shift in the 2024 update: the evaluation must draw on multiple sources of information, across multiple settings, and cannot rely solely on a single screening tool or teacher observation. If a district tried to deny ASD eligibility based on a brief in-school observation without reviewing diagnostic reports or conducting standardized assessments across settings, that evaluation doesn't meet the updated standard.

For parents: if your child has a clinical ASD diagnosis from a pediatric neurologist or developmental pediatrician, and the school's MET is reluctant to find educational eligibility, request the full documentation of the evaluation sources used. A clinical diagnosis alone doesn't guarantee MARSE eligibility, but it is data the team must consider — and a refusal to accept a well-documented clinical diagnosis without a credible countervailing assessment is grounds for an Independent Educational Evaluation (IEE) at public expense.

Practical Steps: Using the 2024 MARSE Updates

The power of these updates lies in the fact that most districts aren't advertising them, and many general education staff don't know they've changed. Parents who cite specific rules by number — Rule 47, Rule 340.1705, Rule 340.1715, Rule 340.1721e — signal to districts that they're operating from current information.

Here's how to deploy this knowledge:

1. Ask for Rule 47 compliance data in writing before your next IEP meeting — specifically, how many students are in your child's SLD classroom and how many students are on their teacher's caseload.

2. Review your child's ESY section of the IEP after the annual review. If the justification box is blank or vague, request the specific data the team used and push for a written explanation.

3. Check meeting attendance records from past IEP meetings. If key team members were absent without your written consent to the excusal, that's a procedural violation you can raise in a State Complaint.

4. For autism eligibility disputes, request the full list of evaluation instruments and data sources the MET used. If the autism-specific assessments don't cover all required domains or settings, the evaluation may not meet the updated Rule 340.1715 standard.

Michigan's 2024 MARSE updates aren't just bureaucratic housekeeping. They're legal guardrails that your child's school is required to comply with — and that you can invoke when they don't.
