Michigan Special Education Eligibility Categories Under MARSE

When a school tells you your child doesn't qualify for special education, they're making a legal determination under a specific set of Michigan rules — not just a general professional opinion. Michigan's eligibility categories are defined in the Michigan Administrative Rules for Special Education (MARSE), and they differ from federal IDEA requirements in ways that matter significantly for families fighting for services.

Understanding how each category works helps you identify when an eligibility denial is legitimate, when it's based on a flawed evaluation, and which category might be the right fit for your child's specific profile.

The Legal Framework: MARSE vs. IDEA

Under federal law (IDEA), students can receive special education if they have one of 13 recognized disability categories and that disability adversely affects educational performance to the degree that the student needs specially designed instruction. Michigan mirrors these 13 categories in MARSE Rules 340.1702 through 340.1717, but adds its own specific criteria that often go beyond — and sometimes contradict — the federal minimum standards.

This matters because a district applying federal standards alone to a Michigan student may incorrectly deny eligibility that would otherwise be established under MARSE's more specific rules. Parents who know the state-specific criteria can challenge eligibility denials more precisely.

Two requirements appear across nearly all categories: the disability must be verified through evaluation, and it must adversely affect the student's educational performance in ways that require specially designed instruction. Accommodations alone (which a 504 plan can provide) don't make a student eligible for special education — there must be a need for instruction delivered differently, not just delivered with supports.

Michigan's 13 Eligibility Categories

1. Autism Spectrum Disorder (ASD) — MARSE R 340.1715

Michigan defines ASD as a lifelong developmental disability that adversely affects educational performance. The evaluation must document impairments in three core areas: reciprocal social interaction, communication (both verbal and non-verbal), and restricted or repetitive patterns of behavior. The disability must be present before age 3 and is not primarily a result of an emotional impairment.

Michigan's ASD category applies whether the student's needs are mild or severe — the "spectrum" framing under MARSE encompasses what was formerly diagnosed as Asperger's syndrome. An IEP for ASD must address the specific areas where the disability affects learning, which often include social pragmatics, sensory regulation, and communication systems.

2. Cognitive Impairment (CI) — MARSE R 340.1705

Michigan's CI category has very specific quantitative thresholds. Eligibility requires development at a rate approximately 2 or more standard deviations below the mean on an individually administered standardized cognitive assessment. Academic achievement must also be documented in the lowest 6th percentile in both reading and arithmetic. And adaptive behavior — the student's ability to function in daily life — must be impaired.

All three criteria must be met. A student with low cognitive scores but average academic achievement may not qualify for CI. A student with academic struggles but average adaptive functioning likewise may not meet the standard.

3. Deaf-Blindness (DB) — MARSE R 340.1717

Applies to students with concomitant hearing and visual impairments whose combined needs cannot be met by programs designed solely for deafness or blindness.

4. Early Childhood Developmental Delay (ECDD) — MARSE R 340.1702

This category applies only to children ages 3 through 5 who demonstrate a developmental delay in one or more areas: physical, cognitive, communication, social/emotional, or adaptive development. It allows young children to receive services without being identified under a more specific disability category. At age 6, the student must be reevaluated under a categorical label if they continue to need services.

5. Emotional Impairment (EI) — MARSE R 340.1706

EI is one of the most contested categories in Michigan because the criteria require that the behavior occurs "over an extended period of time" and to a "marked degree." The behavior must prevent the student from profiting from learning. MARSE explicitly excludes students who are solely "socially maladjusted" unless they also have a concurrent emotional impairment — this exclusionary clause is frequently misapplied by districts to deny EI eligibility for students with conduct-related behaviors.

EI evaluations must include both a school social worker and either a school psychologist or a licensed psychiatrist. This dual professional requirement is often overlooked in districts that try to cut corners.

6. Hearing Impairment (HI) — MARSE R 340.1703

Eligibility requires a permanent or fluctuating hearing impairment that adversely affects educational performance. This includes both deafness (so severe that processing linguistic information through hearing is impossible) and hearing impairments that don't meet the threshold for deafness. Audiological evaluation is required.

7. Other Health Impairment (OHI) — MARSE R 340.1709a

OHI covers chronic or acute health problems — including ADHD, epilepsy, heart conditions, diabetes, cancer, and dozens of others — that result in limited strength, vitality, or alertness and adversely affect educational performance. The key word is "adversely affects" — a student with a chronic health condition who is fully succeeding academically may not meet the educational impact standard for OHI, even with a diagnosis.

OHI is the correct category for many students with ADHD who need specialized instruction beyond what a 504 accommodation plan can provide. Michigan saw a significant increase in OHI identifications after the state tightened SLD criteria in 2010 — many students who would have been identified as SLD were reclassified under OHI or speech-language impairment instead.

8. Physical Impairment (PI) — MARSE R 340.1708

PI covers severe orthopedic and neuromotor impairments — from congenital anomaly, disease, or injury — that adversely affect educational performance.

9. Severe Multiple Impairment (SXI) — MARSE R 340.1710

SXI applies when a student's combination of disabilities creates educational needs so extensive that a single categorical program is insufficient to address all of them.

10. Specific Learning Disability (SLD) — MARSE R 340.1713

SLD is the most contested category in Michigan because of the 2010 rule change that raised the identification threshold significantly. Michigan now requires districts to document the student's response to scientific, research-based interventions (an RTI or multi-tiered system of supports approach) before identifying SLD. Districts must document that the student fails to achieve adequately despite high-quality instruction and scientifically based interventions.

Michigan also allows — but does not require — the pattern of strengths and weaknesses approach. The state no longer allows the discrepancy model (comparing IQ to achievement scores) as the primary basis for SLD identification, though it can be used as part of the evidence base.

This shift explains why Michigan serves a smaller share of students with SLD compared to the national average. Nationally, SLD accounts for about 32% of all special education identifications; Michigan's numbers are significantly lower because the RTI documentation requirements are more demanding.

11. Speech and Language Impairment (SLI) — MARSE R 340.1714

SLI covers articulation, fluency, voice, and language impairments that adversely affect educational performance. Michigan has an unusually high identification rate for SLI — over half of all students with disabilities in Michigan fall into either SLI or SLD, with SLI representing a disproportionately large share compared to national norms. This is partly attributed to students who would have been identified as SLD before 2010 being classified under SLI instead.

12. Traumatic Brain Injury (TBI) — MARSE R 340.1716

TBI covers acquired brain injuries from external force resulting in functional disability or psychosocial impairment; congenital and birth trauma conditions are excluded.

13. Visual Impairment (VI) — MARSE R 340.1704

VI covers students whose visual acuity — even with correction — adversely affects educational performance, including both blindness and low vision.

When a Student Doesn't Fit Neatly Into One Category

Some students have complex profiles that touch multiple categories. MARSE allows a student to be identified under more than one category when they have multiple distinct disabilities, though the primary disability driving the IEP is typically listed first.

When a student is evaluated and doesn't meet the criteria for any MARSE category, the district is supposed to transition the evaluation data into a 504 eligibility discussion if the student has an impairment that substantially limits a major life activity. But a 504 plan provides only accommodations — if your child needs specialized instruction, you need an IEP, and that requires meeting one of the 13 MARSE criteria.

If your child was denied eligibility and you believe the evaluation was inadequate or the criteria were misapplied, you have the right to request an Independent Educational Evaluation (IEE) at public expense. You also have the right to challenge the eligibility determination through state complaint or due process.

The Michigan IEP & 504 Advocacy Playbook covers each MARSE eligibility category in detail and provides the evaluation checklist language parents need to challenge inadequate assessments and misapplied eligibility criteria.

The Eligibility Determination Is Not the End of the Story

Receiving an eligibility determination — even a correct one — is just the beginning. Once eligibility is established, the IEP team must develop goals, identify services, and determine placement. Each of those decisions involves its own set of legal requirements and potential advocacy battles.

But none of that is possible without a legitimate, properly conducted evaluation under the correct MARSE category. Getting the eligibility step right is the foundation for everything that follows.
