Manifestation Determination Review
What it means, what record to check, and what to ask next.
What MDR means in the school record
MDR means Manifestation Determination Review. In an IEP conversation, the practical question is what decision, service, support, or record this term affects for your child.
An MDR is a meeting held after certain disciplinary removals to decide whether the conduct was caused by, or had a direct and substantial relationship to, the child's disability, or was the direct result of the school's failure to implement the IEP.
Why it matters
An MDR requires the team to review disability relationship and IEP implementation before certain discipline changes proceed. Bring discipline, removal, IEP, FBA, BIP, and service records.
What to do when you see MDR
Use this when discipline may change placement or removals are adding up and the team must review disability relationship and IEP implementation.
Check This Record
- Collect suspension, removal, early pickup, and incident records.
- Compare the conduct with disability impact, evaluation data, IEP supports, and BIP implementation.
- Check whether the team reviewed whether failure to implement the IEP directly resulted in the conduct.
Red Flags
- The school treats repeated early pickups as informal instead of tracking removals.
- The MDR ignores missing services or BIP implementation.
- The behavior is discussed without current evaluation or disability data.
Documents to Gather
- Discipline notices
- Incident reports
- IEP
- BIP/FBA
- Service logs
- Attendance/removal record
Sample Finding
The incident happened during unstructured transition, but the IEP's transition support and BIP prevention steps were not reviewed.
What to Write
"Please review the conduct, disability impact, and IEP/BIP implementation data before the team reaches a manifestation determination."
