A Manifestation Determination Review (MDR) can feel overwhelming. It’s overwhelming because it can significantly impact your child’s education. Understanding what’s happening and knowing your rights gives you the confidence to move forward in the best direction.
Confidence means knowing the answers to questions like:
- What happens next?
- Can the school remove my child from their program?
- Will my child lose services?
- What does this meeting actually mean?
To help ensure you, your child, and your family can move forward with the highest confidence, here’s a rundown of what schools require, your available options if you disagree with the decision, plus other key details.
What Is a Manifestation Determination Review?
A Manifestation Determination Review (MDR) is a meeting schools must hold before moving forward with certain disciplinary actions involving a student with an Individualized Education Program (IEP).
These meetings are designed to determine if the student’s disability played a role in the behavior. If the answer is, “Yes, it did,” then the school may be limited in the disciplinary actions it can take.
An MDR is usually required when:
- A student is removed from school for more than 10 consecutive school days
- A student is moved to an Interim Alternative Educational Setting (IAES)
- A pattern of removals results in a change of placement
The meeting must take place within 10 school days of the school’s decision to make a placement change.

The 2 Questions the School Must Answer
Through an MDR, the IEP team must answer two specific questions required under the Individuals with Disabilities Act (IDEA). If the answer to either question is “yes,” that means the behavior is considered a manifestation of the student’s disability.
These are the questions:
- Was the conduct caused by, or did it have a direct and substantial relationship to, the child’s disability?
- Was the conduct the direct result of the school’s failure to implement the IEP?
Regarding the first question, the student’s disability need not be the only cause of the behavior. As long as there’s a direct and substantial relationship between the disability and the conduct of the student, there may be enough to support a manifestation finding. For example, imagine a student with ADHD acts impulsively during a confrontation at school. Even if other factors played a role, the MDR must consider whether the student’s disability meaningfully contributed to the behavior.
Regarding the second question, the MDR must consider whether the school was providing the support, accommodations, and services required by the student’s IEP before the incident. For example, a student’s IEP may require behavioral support. If the student engages in behavior that would otherwise lead to disciplinary action, but the school was not providing required support, that failure could lead to a manifestation finding.

What Happens at a Manifestation Determination Review Meeting?
The IEP team determines whether the student’s behavior is connected to their disability. The MDR exists so that the determination can be made using all available information.
During the MDR meeting, the IEP team will review:
- Who is involved: The student’s IEP team, including the parents
- What information is considered: The IEP team’s observations, teacher observations, evaluations, school records, and other relevant information
- What the team is deciding: Whether the behavior was a manifestation of the student’s disability under one of the two IDEA standards

Parents are not simply there to observe. They are equal members, and they have the right to ask questions, share information, present evidence, and disagree with the outcome if they believe the full picture has not been considered.
To prepare for the meeting, parents may want to bring:
- Independent evaluations
- Prior IEP meeting notes
- Progress reports
- Medical or psychological records
- Emails or other communications with the school
- Documentation showing concerns about IEP implementation
Parents must understand the importance of these meetings in advance so they can prepare properly. The decision made during the meeting can affect a student’s placement, services, and educational future, which is why everybody’s input matters.

What Happens After the Meeting?
An MDR results in one of two findings. Either the behavior was a manifestation of the student’s disability, or it wasn’t. Each outcome carries different legal consequences that affect disciplinary action, educational services, and a student’s placement moving forward.
If the IEP determines the behavior was a manifestation of your child’s disability, the school generally cannot move forward with an expulsion or long-term suspension. The focus shifts from discipline to support. The school may need to conduct a Functional Behavior Assessment (FBA), update the student’s Behavior Intervention Plan (BIP), and return the student to their current placement unless exceptions apply. The district must also continue providing the educational services your child needs.
If the IEP determines the behavior was not a manifestation of your child’s disability, the school may move forward with disciplinary action. This determination does not mean your child’s rights disappear. The district must still provide educational services, and parents have the right to challenge the decision through an expedited due process hearing if they believe the outcome was incorrect.

How Do Schools Mishandle Manifestation Determinations? (and What Can Parents Do About It?)
Not every MDR is handled correctly. In some cases, limited information or an incomplete understanding of the MDR process leads to an incorrect finding. In others, there may be issues with how the meeting itself was conducted.
These are some of the most common issues that emerge during the MDR process:
- Requiring the disability to be the main cause of the behavior: This is one of the most common mistakes. The law does not require the disability to be the sole or primary cause. The question is whether there was a direct and substantial relationship between the disability and the behavior.
- Focusing only on the incident itself: Sometimes the discussion centers entirely on what happened that day while giving little attention to evaluations, behavioral data, teacher observations, or the student’s history. MDR participants are required to review all relevant information, not just the disciplinary report.
- Overlooking any failures to follow the IEP: If the school was not providing the supports, accommodations, or services required by the IEP before the incident occurred, that should be part of the discussion. Failure to implement the IEP may be enough on its own to support a manifestation finding.
- Holding the meeting without meaningful parent involvement: Parents should receive proper notice and a substantive opportunity to participate. Being informed of the decision afterward is not the same as being part of the process.
- Treating the meeting as a formality: An MDR is a team decision. The principal’s recommendation is not the final word. All MDR participants must independently review the facts before reaching a conclusion.
If you believe the team reached the wrong decision, taking fast action is essential. Parents have the right to challenge an MDR outcome, but timelines can move fast. If you want to challenge a decision, do the following as quickly as possible:
-
- Request all documentation from the meeting in writing
- File for an expedited due process hearing to challenge the decision
- Contact a special education attorney
The sooner potential errors are identified, the more options are available. Waiting until disciplinary decisions have already taken effect will make the situation more difficult to address.

Manifestation Determination Review (FAQs)
Can a Parent Disagree With the Outcome of a Manifestation Determination?
Yes. Parents who disagree with the MDR finding have the right to file for an expedited due process hearing — typically resolved within 20 school days given the urgency of the student’s placement being at stake.
What Happens to My Child’s Education During a Suspension While an MDR Is Pending?
The school district must continue providing educational services that allow the student to participate in the general curriculum and make progress toward IEP goals — a suspension does not eliminate that obligation.
Can a School Expel a Student With an Iep?
Only if the MDR finds the behavior was not a manifestation of the disability. Even then, the district must continue providing a free appropriate public education (FAPE) throughout the expulsion period.
What Is the Difference Between a Manifestation Determination Review and a Due Process Hearing?
An MDR is a school-based team meeting that determines whether a behavior is related to a student’s disability. A due process hearing is a formal legal proceeding before an administrative law judge. The MDR comes first — due process is the appeal mechanism if parents disagree with the outcome.
