Manifestation Determination Reviews (MDR)
When a student with a disability faces serious discipline, the law requires a review of whether the behavior was caused by the disability. This guide covers both IDEA’s formal MDR process for students with IEPs and Section 504’s parallel disciplinary protections for students with 504 plans.
What Is a Manifestation Determination Review?
A Manifestation Determination Review (MDR) is a meeting required under IDEA when a school district seeks to discipline a student with a disability in a way that constitutes a change of placement — typically a suspension of more than 10 school days in a year, or an expulsion. The purpose of the MDR is to determine whether the behavior that led to the discipline was caused by, or substantially related to, the child's disability — and whether it was a direct result of the district's failure to implement the child's IEP.
This is a critical protection. Without the MDR requirement, students with disabilities could be expelled for behaviors that are direct expressions of their disability — effectively removing them from their educational placements based on symptoms of the condition that qualifies them for special education in the first place. The MDR is a safeguard that requires the team to examine the connection between disability and behavior before serious discipline proceeds.
⚖️ IEP Students vs. 504 Students: How Disciplinary Protections Differ
Students with disabilities can have protection under two different federal laws when it comes to school discipline. The law that applies to your child depends on whether they have an IEP under IDEA or a 504 plan under Section 504 of the Rehabilitation Act — and the procedural details differ meaningfully between the two.
📋 IDEA — Students with IEPs
- MDR is an explicit statutory requirement under 20 U.S.C. §1415(k)
- Must be convened within 10 school days of a disciplinary change-of-placement decision
- Two-part test is codified in federal law — identical standard in all 50 states
- FBA and BIP review are required by statute when manifestation is found
- Child retains FAPE — services must continue even during removal
- Parent may request expedited due process hearing to challenge outcome
- Stay-put applies during expedited due process appeal
- Enforcement: IDEA due process hearing and/or state complaint
📋 Section 504 — Students with 504 Plans Only
- No explicit “MDR” language in the statute — protections are derived from OCR guidance and the “significant change of placement” doctrine
- No specific day-count trigger codified in statute — but OCR applies a similar “significant change of placement” analysis
- Standard: Was the behavior caused by the disability, and did the district properly implement the 504 plan?
- No explicit FBA/BIP statutory requirement — but reviewing and updating the 504 plan is appropriate when behavior may be disability-related
- District should ensure appropriate education continues during removal
- No automatic IDEA stay-put right during appeal
- Enforcement: OCR complaint (free; within 180 days of the discriminatory act) and/or state 504 due process if available
Side-by-Side Comparison
| Feature | IDEA — IEP Students | Section 504 — 504-Only Students |
|---|---|---|
| Legal authority | 20 U.S.C. §1415(k); 34 CFR §300.530 | Section 504, Rehabilitation Act; 34 CFR Part 104; OCR guidance |
| Explicit “MDR” in statute? | Yes — explicit statutory requirement | No — derived from OCR interpretation of “significant change of placement” doctrine |
| Trigger threshold | Disciplinary action constituting a change of placement — typically more than 10 consecutive school days or a pattern of removals; must be convened within 10 school days of the decision | No specific day-count codified; OCR applies a significant-change-of-placement analysis; families may wish to request a review any time serious discipline is proposed |
| The test applied | (1) Was the behavior caused by or substantially related to the disability? (2) Was the behavior a direct result of the district’s failure to implement the IEP? “Yes” to either = manifestation | Was the behavior caused by the disability? Did the district properly implement the 504 plan? OCR applies a similar analysis; the standard is whether excluding the student constitutes disability discrimination |
| Required team | Parent + relevant IEP Team members; parent is a required participant | No explicit statutory team composition — but the 504 team and parent should be involved; district typically convenes the 504 team |
| If manifestation IS found | Cannot expel or long-term suspend for this behavior; must conduct FBA / revise BIP (required by statute); return to prior placement unless parties agree otherwise | Discipline based on behavior caused by the disability may constitute discrimination under Section 504; district should review and update the 504 plan; families may wish to document concerns and consider an OCR complaint if exclusion proceeds |
| If no manifestation | Regular discipline may apply; child must still receive educational services during removal; parent may appeal via expedited due process | Regular discipline may apply; district should continue appropriate educational services; parent may file an OCR complaint if they believe the finding was incorrect or discriminatory |
| Services during removal | FAPE must continue; services to participate in general curriculum and make IEP progress required (after day 10 of cumulative removal) | District should provide appropriate educational services; Section 504 requires meaningful educational access; specific services should be determined with the 504 team |
| Appeal mechanism | Expedited IDEA due process hearing (within 20 school days; decision within 10 school days after hearing); also IDEA state complaint | OCR complaint (free; file within 180 days); Section 504 due process hearing if available in the state; some districts have internal 504 appeal procedures |
| Stay-put during appeal | Yes — IDEA stay-put applies when expedited due process is requested; child remains in current placement during pendency | No automatic statutory stay-put equivalent; parents may request interim arrangements but IDEA’s stay-put provision does not apply to 504-only students |
What If My Child Has Both an IEP and a 504 Plan?
Some students have both an IEP and a 504 plan. In that situation, IDEA’s MDR process governs — IDEA is the more specific statute and provides more detailed procedural protections. Having a 504 plan alongside an IEP does not change or reduce the IDEA MDR requirements. The IDEA framework, including the 10-day trigger, the two-part test, and the FBA/BIP requirement, applies in full.
When Is an MDR Required? (IDEA & IEP Students)
⚖️ Federal IDEA Right (All States): Under IDEA 34 C.F.R. § 300.530, an MDR must be convened within 10 school days of any decision to change the placement of a child with a disability due to a violation of a code of student conduct — whenever that disciplinary action constitutes a change of placement. This 10-day threshold is a federal floor; states may not provide fewer protections.
What Counts as a "Change of Placement" for Discipline Purposes?
| Situation | MDR Required? |
|---|---|
| Suspension of more than 10 consecutive school days | ✅ Yes — triggers MDR and change-of-placement protections |
| Series of shorter suspensions that total more than 10 school days in a school year and constitute a pattern | ✅ Yes — pattern of removals may constitute a change of placement |
| Expulsion or long-term removal | ✅ Yes — always requires MDR |
| Placement in an Interim Alternative Educational Setting (IAES) for weapons, drugs, or serious bodily injury | ✅ Yes — MDR required even for these "special circumstances" |
| Short-term suspensions totaling 10 or fewer school days with no pattern | ❌ No — but district must provide services after day 10 of cumulative removal in the year |
| In-school suspension where child still has access to curriculum and IEP services | ❌ Typically no — not considered a removal if services continue |
The Two-Part Manifestation Test (IDEA)
⚖️ Federal IDEA Right (All States): The two-part test is defined in federal law and applies uniformly in all states. The team reviewing the MDR must include the parent and "relevant members of the IEP Team" (called by different names in different states, but subject to the same federal requirements).
At the MDR meeting, the team — which must include the parent and relevant members of the IEP Team — reviews all relevant information in the child's file and asks two specific questions. A "yes" to either question means the behavior IS a manifestation of the disability.
Question 1: Was the conduct caused by, or did it have a direct and substantial relationship to, the child's disability?
This asks whether there is a direct link between the disability and the behavior. For example: a child with ADHD who acted impulsively; a child with autism who melted down in response to a sensory trigger; a child with an emotional disability whose behavior was a symptom of that condition. The team must genuinely examine this connection — not simply conclude "no" because the behavior was also a rule violation.
Question 2: Was the conduct a direct result of the district's failure to implement the IEP?
This asks whether the district failed to deliver the services, supports, or accommodations written in the IEP — and whether that failure contributed to the behavior. For example: a child's IEP included a behavioral support plan that was not being implemented, or a child's sensory accommodations were not in place. If the answer to either question is yes, manifestation is found.
What Happens Based on the MDR Outcome
The district may NOT expel or long-term suspend the child based on this incident.
- The district must conduct a Functional Behavioral Assessment (FBA) if one has not been done, or review and revise the existing Behavioral Intervention Plan (BIP) — this is a federal IDEA requirement when manifestation is found
- The child must be returned to the original placement, unless the parent and district agree to a change of placement as part of a revised IEP — or unless a "special circumstances" removal (weapons, drugs, serious bodily injury) applies
- If IEP implementation failure was found, the district must take immediate steps to remedy the failure
- The child continues to receive FAPE during any removal — services must continue
- Parent retains all IEP rights and dispute resolution options
The district may apply the same disciplinary procedures it would apply to students without disabilities.
- However, the child must still continue to receive educational services — a child with a disability cannot simply be expelled with no services
- During any removal, services must be provided to enable the child to continue to participate in the general curriculum and to progress toward IEP goals
- The IEP Team determines the appropriate services during the removal
- Parents retain the right to appeal the MDR determination through due process — including requesting an expedited hearing
- Requesting an expedited due process hearing will trigger a "stay put" order maintaining the child's current placement
Functional Behavioral Assessments (FBA) and Behavioral Intervention Plans (BIP)
⚖️ Federal IDEA Right (All States): When manifestation is found, IDEA requires that the district conduct an FBA (if one has not already been conducted) and develop or review/revise the BIP. This requirement applies in every state.
An FBA is a structured process of gathering and analyzing data to understand the function a behavior serves for the child — what need the behavior is meeting, what triggers it, and what consequences maintain it. A BIP is the plan developed from that analysis, specifying proactive strategies, teaching replacement behaviors, and reactive protocols. Together they are the cornerstone of behavioral support in special education.
When IDEA Requires an FBA
- When a manifestation is found after an MDR
- When a child is placed in an IAES (special circumstances removal)
- When a child's behavior is impeding their learning or the learning of others — best practice at any IEP meeting where behavior is discussed
- When a parent requests one as part of a comprehensive evaluation
What a Quality FBA Should Include
- Direct observation of the behavior across settings
- Antecedent analysis (what happens before the behavior)
- Consequence analysis (what happens after)
- Function hypothesis (what need is the behavior serving?)
- Input from parents, teachers, and other providers who know the child
- Review of prior behavioral data and any previous BIP
How MDR Procedures May Vary by State
While the core MDR process and the two-part test are federal requirements under IDEA that apply in all 50 states, individual states may add procedural protections beyond the federal minimum. The following table summarizes some known variations. Families should verify current requirements with their state education agency or a qualified special education attorney.
| State | IEP Team Name | Notable State-Specific Notes |
|---|---|---|
| Federal Floor (All States) | IEP Team (federal term) | 10-day threshold; two-part test; FBA/BIP required if manifestation found; FAPE continues during removal (34 CFR §300.530); applies in every state |
| New York | CSE — Committee on Special Education | State Part 200 regulations implement IDEA and may add procedural steps; state forms may differ from other states; federal two-part test applies |
| Texas | ARD Committee — Admission, Review, and Dismissal | Texas Education Code Ch. 37 adds disciplinary provisions; DAEP placements may carry additional procedures; federal IDEA floor applies |
| New Jersey | Child Study Team (CST) | NJ adds specific procedural rights in disciplinary matters under N.J.A.C. 6A:14; federal floor applies; state guidance available through NJDOE |
| California | IEP Team | California Education Code adds parent notification and procedural rights in disciplinary proceedings; IDEA floor applies |
| Florida | IEP Team | Florida State Board of Education rules implement IDEA; Bureau of Exceptional Education and Student Services provides state guidance |
| Pennsylvania | IEP Team | 22 Pa. Code Ch. 14 implements IDEA; state adds procedural timelines and documentation requirements; federal floor applies |
| Illinois | IEP Team | Illinois School Code implements IDEA with state additions; ISBE provides state-specific procedural guidance; federal two-part test applies |
Red Flags in the MDR Process
Parents are required members of the MDR team. An MDR held without the parent — or with inadequate notice — may be procedurally deficient. If you were not meaningfully invited or your participation was not genuinely facilitated, document this concern immediately.
The team must specifically ask whether the behavior was a direct result of failure to implement the IEP — not just whether the behavior relates to the disability. If no one reviewed whether the IEP services and supports were actually being provided, the review may be incomplete.
If the determination appears to have been decided before the meeting and the meeting is merely a formality — without genuine review of data or parent input — this raises serious concerns about the validity of the process and meaningful parent participation.
When manifestation is found, IDEA requires an FBA (if not done) and review/revision of the BIP. If neither happens after a manifestation finding, the district may not be fulfilling its obligations to address the root cause of the behavior.
Regardless of the MDR outcome, the child must continue to receive educational services during any removal of more than 10 school days. If services are simply stopped during a long-term suspension or IAES placement, that may be a significant IDEA violation.
If a child is repeatedly suspended for 1–3 days at a time with the total approaching or exceeding 10 school days per year, this pattern may constitute a change of placement requiring MDR protections — even if no single suspension exceeds 10 days.
Parent Rights in the MDR Process
- You are a required member of the MDR team — you must be invited and your participation must be genuinely facilitated.
- You have the right to review all relevant information before the meeting — including the child's IEP, evaluation reports, disciplinary records, and behavioral data.
- You may bring an advocate, attorney, or support person to the MDR meeting.
- You may disagree with the MDR determination — and if you do, you have the right to appeal the decision through an expedited due process hearing, which must be held within 20 school days and a decision issued within 10 school days after the hearing.
- If you request an expedited due process hearing challenging a removal, IDEA's "stay put" provision applies — the child remains in the current placement (or returns to it) during the pendency of the hearing, unless the parties agree otherwise or the removal involves weapons, drugs, or serious bodily injury.
- You retain all procedural safeguards throughout the disciplinary process — including the right to receive a Procedural Safeguards Notice.
