Manifestation Determination (MDR)
A meeting held when a child with a disability faces a disciplinary action (like removal for more than 10 consecutive school days, or a pattern of shorter removals that constitutes a change of placement). The team must determine whether the behavior was caused by the child's disability. If so, the school cannot use the same discipline as for non-disabled students.
Federal rule: 34 CFR § 300.530(e) — Manifestation determination
Where MDR shows up in your IEP
This is a meeting and a form, not a section of the IEP. The form asks two questions: whether the conduct was caused by or had a direct and substantial relationship to your child's disability, and whether it resulted from the school failing to implement the IEP. Bring the IEP, the behavior plan, and your own notes — the second question is the one nobody checks.
What to ask at the meeting
- Was every part of the IEP actually being delivered on the day this happened?
- Which documents did the team review before answering these two questions?
- If the answer is yes, what does my child's week look like from here?
Red flags
- The meeting is set without you, or at an hour you have already said you cannot attend.
- The form is filled in before anyone opens the IEP or the behavior plan.
- Nobody asks whether the services on paper were being delivered that week.
Example
Malik faced an eleven-day removal after a hallway incident. At the meeting his mother pointed out that his aide had been reassigned for three weeks, which the sign-in sheets confirmed. The team found the conduct was a manifestation, the removal was withdrawn, and his behavior plan was reviewed with the aide's coverage written in this time rather than assumed.
Common questions
How quickly does this meeting have to happen?
Within ten school days of the decision to change placement because of a conduct violation. You are a required participant alongside the district and the relevant members of the team, so a date chosen without you is worth pushing back on.
What does a manifestation finding change?
Your child generally returns to the placement they came from, and the team conducts a behavioral assessment and puts a plan in place, or reviews the one that exists. It stops the removal rather than excusing the behavior — the point is that the plan gets fixed.
What if the IEP simply was not being followed?
That is the second question, and it stands on its own. When conduct is the direct result of the district failing to implement the IEP, the conduct is a manifestation and the district must take immediate steps to remedy the deficiency.
Related Terms
Behavior Intervention Plan (BIP)
A plan that describes specific strategies and supports to address challenging behaviors identified through a Functional Behavioral Assessment. It focuses on teaching replacement behaviors and preventing problem behaviors.
Functional Behavioral Assessment (FBA)
A process to understand why your child behaves in certain ways. It looks at what happens before and after a behavior to identify triggers and what the child gets from the behavior, so the team can develop better strategies.
Discipline
Special rules apply when a child with an IEP faces school discipline. For suspensions over 10 days, the school must hold a manifestation determination and continue to provide FAPE.
