Manifestation Determination Examples: What Counts and Why It Matters

If you’re here because your child is facing suspension, expulsion, or a big disciplinary change—take a breath. A Manifestation Determination Review (MDR) is a meeting where the school must decide whether your child’s behavior was connected to their disability (or the school’s failure to follow the IEP).

This matters because it can change what happens next: discipline, placement, and what supports the team is required to put in place. I’ve sat through dozens of these with families, and I’m going to walk you through what an MDR is, when it’s required, and what to say so you don’t go into the meeting blind.

MDR at a Glance

• A Manifestation Determination Review (MDR) is a required meeting when a student with an IEP (and sometimes a 504) faces serious school discipline.
• The team must decide whether the behavior was caused by, or directly related to, the student’s disability or the school’s failure to follow the IEP.
• If the answer is yes, the school cannot discipline the student in the same way it would a nondisabled student.
• The outcome affects discipline, placement decisions, and what supports or plan changes must happen next.

A Manifestation Determination Review (MDR) is a required process where the team decides whether the behavior was caused by, or had a direct link to, your child’s disability—or whether it happened because the IEP wasn’t followed. I’ve been to dozens of these with families, and I’ll walk you through exactly what to expect and what to ask.

What is a Manifestation Determination?

A Manifestation Determination is required by IDEA 2004 when a school is considering suspending or expelling a student with an IEP. It’s a legal review to answer two questions:

1. Was the behavior a manifestation of the child’s disability?
2. Was the behavior caused by the school’s failure to implement the IEP?

You’ll hear it called:

• MDR (Manifestation Determination Review)
• MDH (Manifestation Determination Hearing)

Same thing. Different acronyms. Below is the snippet from IDEA.

When Does a Manifestation Determination Happen?

It’s required when a disciplinary change in placement is being considered, usually after the student has been removed for more than 10 school days in a year.

BUT—and this is important—the school doesn’t have to wait until 10 days have passed to hold the MDR. If they try that excuse, point them to your Procedural Safeguards. (I’ve included the screenshots)

Wait! Let’s look at that again.

Highlighting is mine. But what this means is, the school does not have to wait for the full 10-days, or whatever the threshold is, before holding a Manifestation Determination Review. Keep that in mind if you are told “Well, we have to wait for 10 days because….” No, they do not.

What the MDR Team Is Required to Decide

A Manifestation Determination Review is not a general discussion about behavior, attitude, or consequences. The team is legally required to answer two specific questions—and both must be considered carefully.

First, the team must decide whether the behavior was caused by, or had a direct and substantial relationship to, the student’s disability. This includes not just diagnoses listed on the IEP, but how those disabilities actually show up in school—impulsivity, emotional regulation, sensory overload, communication breakdowns, or executive functioning challenges.

Second, the team must decide whether the behavior was the direct result of the school’s failure to implement the IEP. That means looking closely at whether supports, services, accommodations, or behavior plans were actually provided as written. If something wasn’t implemented consistently—or at all—that matters.

If the answer to either of these questions is yes, the behavior is considered a manifestation of the disability. This is why MDR meetings should focus on documentation, data, and how the IEP was working in real life—not opinions, assumptions, or how frustrated everyone feels in the moment.

What Happens after the MDR YES/NO questions?

If the behavior was a manifestation of the disability:

The school cannot continue discipline in the same way it would for a student without disabilities. The team must take a step back and look at supports instead of punishment.

That usually means reviewing and revising the IEP and any existing behavior plan. If the student does not already have a Behavior Intervention Plan, the team should move forward with a Functional Behavior Assessment (FBA) to better understand what’s driving the behavior. In most cases, the student returns to their original placement, unless the parent and school agree on a different setting.

If the behavior was not a manifestation of the disability:

The school is allowed to apply the same disciplinary consequences it would use for any other student under the code of conduct.

That said, you are not required to agree with the decision. You can note your disagreement on the MDR paperwork and ask about next steps, including the district’s appeal or dispute resolution process. A “no” determination is not the end of the conversation—it just changes what happens next.

Why I Ask for an MDR After Every Suspension

And here’s what I do, as an Advocate for my clients. I ask for an MDR after every single suspension. Yes, even the first one. Even if it’s only a day. And yes, I usually get told “no.”

Why do I ask anyway?

• It builds a paper trail.
• It signals to the school that the family knows their rights.
• It reminds the team: we want support, not punishment.
• It often leads to an FBA, behavior plan revision, or at the very least, a deeper conversation.

You don’t need to write a legal memo. Just send an email:

“Dear School, I request an MDR for my child regarding the April 15 incident. I believe the behavior was a manifestation of their disability. I’m available these dates…”

They’ll likely tell you they can’t. They’ll say they have to wait. They don’t. Show them the law. Yes, even the first. I do. And I’m usually told no. But here’s why I do it.

• As parents and advocates, we want our kids to be supported rather than punished.
• The suspension worthy behavior tells me that something is not working with either the IEP or the Behavior Plan. And I want it fixed.
• It creates my paper trail, should the situation deteriorate.
• The school is now aware that I (or my client) are aware of both the regulations and Procedural Safeguards. And that we want the child supported and behavior modified. Remember, there is no pedagogical argument for suspending a child. None.

This doesn’t have to be complicated. A simple email with “Dear school, I wish to request an MDR for my child for the incident of 02-05-2026. I believe that his behavior was a manifestation of his disability and the team needs to discuss this. I am available these dates and times.”

Expect them to say “No.” They usually do. I particularly like the “well, we can’t, we have to wait until…” and then I point to the Procedural Safeguards. That usually gets us a new FBA at the very least.

First Steps for Parents

When the school calls or emails about a Manifestation Determination Meeting, the first thing you need to do is calm down. That’s not condescending–it’s strategy. You’re upset. Of course you are. But this meeting is serious and you need your head in the game.

Do not let school staff minimize this:

“Oh, it’s no big deal—you don’t even have to come…”
It IS a big deal. Be there.

This is often part of the School-to-Prison Pipeline, and we need to stop that train in its tracks.

Read all the documents before you sign anything.

I have had many situations where a client was suspended from school. It’s chaotic. It’s stressful. You got called away from work, or wherever you were. You’re upset and maybe embarrassed, but you have to keep calm and focused.

Don’t Sign Anything, Seriously. I have had parents, under duress, sign forms that were put in front of them, and it was agreeing to an alternative school (aka mini jail).

This is the chaos part. You get the call. You leave work. You rush to the school. Your kid has just done something suspension-worthy. And now someone is sliding paperwork across the desk saying,

“Just sign this, and you can take them home.”

Don’t. Sign. Anything.

I’ve seen parents unknowingly:

• Waive their right to an MDR.
• Agree to alternative placements (like alternative ed).
• Miss their opportunity to hold the school accountable.

Already signed? It’s okay. Fix it:

“I was upset and under duress. I am rescinding my agreement to [X]. I am requesting an MDR and IEP meeting for the incident on May 15.”

How to Prepare for a Manifestation Determination Hearing

1. The first thing you want to do is gather data. Ask for all incident reports and files that the school has related to this incident.
2. Know your state’s Special Education Regulations. Some states have variances on suspensions, expulsions and AEDY. Familiarize yourself with these before you start.
3. Prepare your research on your child’s disability. What you want to gather is signs/symptoms/manifestations of your child’s disability. For example, a classic hallmark of ADHD is impulsive behavior.
4. Gather the current IEP and behavior plan for your child. You also want to have any recent notes or emails from teachers that may offer a window into the situation. Such as, “his aide was absent again today.”
5. Go to your school district website and read/print their discipline policy. Make sure that your child was not punished more severely than his/her non-disabled peers would be in the same situation.
6. Read your IEP Procedural Safeguards. You should receive a copy every year. Read them! Discipline is in there.
7. Next, you want to prepare your worksheet. I have a copy of PA’s worksheet below. You can look for one on the website of your state’s Parent Training Center, or use this one.
8. Brainstorm anything that could be relevant and bring the documentation for it. What I mean by this is: Many times our kids are bullied. Parents ask for help, they don’t receive. Disabled child reaches his/her breaking point, and lashes out at bully. And gets suspended. Mind you, not condoning violence. But if they were provoked, that needs to be brought up.
9. Ask for appropriate IEP or Behavior Plan changes in writing. This is the time, follow up in writing if necessary. But if things need to change, now is the time to start the discussion.

What to Bring to a Manifestation Hearing

This is what you bring to the table:

• Incident reports
• Discipline files
• IEP and behavior plan
• Teacher emails or notes (Example: “His aide was out again today.”)
• Your school’s discipline policy
• Your Procedural Safeguards (yes, read them)
• Research on your child’s disability (e.g., impulsivity = ADHD symptom)

Also, prepare your own worksheet or download one from your state’s Parent Training Center.

Tip: Document everything. If your child was bullied and lashed out, say so. Bring proof. Not excusing behavior, but context matters.

Common MDR Mistakes

I can’t even tell you how many mistakes I’ve seen during MDR hearings. One time, it was so bad, I excused myself and went to the parking lot and called a special education attorney. The district was that misinformed and trying to push things through that were just wrong.

Over the years, I’ve seen the same issues come up again and again during Manifestation Determination meetings. These missteps can lead to decisions that don’t fully reflect what’s really happening for the student.

One common mistake is treating the MDR as a formality instead of a required analysis. Sometimes the decision feels made before the meeting even starts, with little meaningful discussion about the disability or how the IEP was being implemented.

Another problem is focusing on the behavior in isolation. Teams may spend a lot of time discussing what the student did, but very little time connecting that behavior to disability-related needs like emotional regulation, impulsivity, sensory overload, or executive functioning challenges.

IEP implementation issues are also frequently overlooked. Supports, accommodations, or behavior strategies may be listed in the IEP but inconsistently provided. If the IEP wasn’t followed as written, that must be part of the MDR discussion, even if it’s uncomfortable. Especially then!

I also see teams rely on opinions instead of documentation. Statements like “we don’t think it’s related” or “he made a bad choice” are not a substitute for data, progress monitoring, service logs, or behavior records.

Finally, MDR meetings sometimes drift into discipline planning before the manifestation decision is even made. The law requires the team to answer the manifestation questions first. Consequences and next steps come later.

If an MDR feels rushed, dismissive, or disconnected from the IEP, it’s reasonable to slow the process down and ask for clarification or additional documentation before moving forward. If you hear the ole’ “well we have to…” just pause and ask for that. “Can you direct me to where it says that in school policy or IDEA? I need to read up on this.”

Manifestation Determination Review Examples

When you get to your meeting, someone from your child’s school will have theirs printed out. This is what the team will go over. Make sure you have read over your state-specific policies.

For example, in PA, a child with an intellectual disability cannot be suspended for even one day without a Manifestation Determination Review.

Attending a Manifestation Determination Review

Both parents should attend the Manifestation Determination Meeting if possible. The child should attend. You can also bring people who have professional knowledge of your child. It would be nice if you could get a doctor to be present, but that doesn’t often happen.

Still, you could ask your child’s therapist, wraparound behavior person, or case manager if they would be willing to speak on your child’s behalf. Having an advocate who has been there before is always nice. And I would definitely find an attorney if the school plans on pressing charges.

Someone on the team will start going through the questions on the form. The team answers and discusses them. At the Manifestation Review, present your factual information in a calm and professional manner.

It is been my experience that it is not as hard to get the team to agree that it was a manifestation of the disability. But it is very difficult to get the team (made up mostly of school personnel) to agree that the IEP was inadequate or not being followed.

(In other words, the school’s fault.) And that is often the case!

I have had many clients with a 1:1 for behaviors and their behavior occurred while the 1:1 was at lunch, or called in sick, or whatever. Depending on your individual situation, you will have to determine if that is a battle you wish to fight.

An Advocate’s Perspective on MDR Meetings

I have a post about gaslighting and IEP meetings. Honestly, I have been gaslighted at more Manifestation Hearings than any other type of meeting.

There was a point in my career where I was sometimes attending 2 or 3 of these in a day, so I knew what to expect. And still, the school board members would look directly at me and say, “No, you are wrong.”

It was like talking to a rock. Say your peace. But if you are not getting anywhere, follow up in writing and consider filing a state complaint. You can also ask them to show you what they are telling you.

Again, stay calm. This is one of the most stressful things a parent will have to do. I personally think they are much more stressful than IEP meetings. This is also another reminder to keep great records on your child and do everything in writing.

If your child has been having behaviors and you’ve been asking for an FBA and have been turned down, this would be a great time to have several emails to show them and remind them that you have been trying to solve this.

When an MDR Does Not Change the Disciplinary Outcome

There are a few very specific situations where a Manifestation Determination does not stop the school from moving forward with a disciplinary removal, even if the behavior is related to a disability.

Under IDEA, schools are allowed to place a student in an interim alternative educational setting when the incident involves certain serious safety violations at school, on school grounds, or at a school-sponsored activity. In these situations, the MDR still happens, but the outcome does not automatically override the disciplinary removal.

What’s important for parents to know is this: An MDR is still required, and the school is still responsible for providing educational services. The student does not lose the right to access instruction or special education supports during this period.

These cases are handled differently because of safety concerns, but they are narrow and specific. Schools should not stretch this exception to fit situations that don’t clearly meet the criteria. In these situations, you will unfortunately learn a new special education acronym–IAES. Interim Alternative Education Setting–an alternative school. (PA refers to this as AEDY, so your state may also call it something else.

If a school claims this exception applies, it’s reasonable to ask for the documentation they are relying on and clarification about how services will continue during the placement.

When This Doesn’t Work — and What to Do Next

Sometimes, even with preparation, an MDR decision doesn’t go the way you expected. That doesn’t mean your child’s disability isn’t real, and it doesn’t mean you did anything wrong. It means the team interpreted the information differently.

When that happens, your next steps usually shift to documenting concerns, requesting clarification in writing, and asking about appeal or dispute-resolution options. In many cases, it’s also a signal to strengthen the IEP itself—especially behavior supports, data collection, and implementation—so the next review is grounded in clearer evidence.

If you are looking for data and documentation tools and templates, those can be found in the Parent IEP Toolkit. If you want to read up more on discipline and behavior, there are links below for you.

Remember, successful advocacy is never one meeting, one email, one grand gesture–it’s a series of little steps, chipping away at issues bit by bit. It’s a long game.
