Manifestation Determination in New Mexico: What Parents Need to Know

Your child with a disability was suspended for 11 days. Or the district is talking about a long-term suspension or expulsion. The word "manifestation" gets mentioned. This is one of the highest-stakes moments in special education — and New Mexico law gives you specific protections that activate automatically at this point.

The 10-Day Trigger

Under NMAC 6.31.2.13 and federal IDEA regulations, a school cannot remove a student with a disability from their current educational placement for more than 10 cumulative school days in a single academic year without triggering additional procedural requirements.

The moment a removal would exceed 10 cumulative days, that removal constitutes a "disciplinary change of placement." When this happens, the district must:

1. Notify you of the disciplinary decision and provide a copy of your procedural safeguards on the same day the decision is made.
2. Conduct a Manifestation Determination Review (MDR) within 10 school days of the decision.

This is not optional. The school principal cannot unilaterally decide to extend a suspension past 10 days without triggering these requirements. The authority to determine what educational services your child receives during any long-term removal rests entirely with the IEP team — not the principal or district administrators alone.

What Happens in an MDR Meeting

The MDR team consists of the parents and relevant members of the IEP team. The team must answer two specific questions about the behavior that led to the discipline:

Question 1: Was the conduct caused by, or did it have a direct and substantial relationship to, the student's disability?

Question 2: Was the conduct the direct result of the school district's failure to implement the student's IEP?

These are not judgment calls the district makes unilaterally. You are a full member of the MDR team, and your input on both questions is legally required.

If the Answer to Either Question Is "Yes"

When the MDR team answers yes to either question, the behavior is legally classified as a manifestation of the disability. The consequences are immediate and significant:

• The student cannot be subjected to standard exclusionary discipline for this behavior. The expulsion or long-term suspension cannot proceed.
• The student must be returned to their previous placement, unless you and the district agree to a different placement as part of modifying the IEP.
• The IEP team must either conduct a Functional Behavior Assessment (FBA) and implement a Behavior Intervention Plan (BIP), or review and modify an existing BIP to address the targeted behavior.

If the school failed to implement the IEP — Question 2 — and that failure contributed to the behavior, the district bears direct responsibility. This is a powerful protection: if your child's behavior escalated because the district stopped providing their scheduled counseling services, or never implemented the sensory break accommodation that was in the IEP, the manifestation determination should be "yes" on Question 2.

If the MDR Team Says "No"

If the team determines the behavior was not a manifestation, standard school disciplinary procedures may apply. But even in this scenario, New Mexico enforces an absolute requirement: the student must continue to receive FAPE during the expulsion period. The IEP team must design services that allow the student to participate in the general education curriculum and continue progressing toward their IEP goals, even while excluded from the regular school building.

This is a critical distinction from what happens with non-disabled students. A non-disabled student who is expelled may simply be out of school. A student with a disability must continue to receive specially designed instruction as outlined in their IEP.

Special Circumstances: When 45-Day Placements Apply

Federal law and NMAC recognize three "special circumstances" in which a school can remove a student to an Interim Alternative Educational Setting (IAES) for up to 45 school days, regardless of whether the behavior was a manifestation:

1. The student carried or possessed a weapon at school or a school function
2. The student knowingly possessed or used illegal drugs, or sold or solicited the sale of a controlled substance
3. The student inflicted serious bodily injury upon another person at school or a school function

Even in these cases, FAPE must continue. The IEP team still meets to design appropriate services in the IAES setting, and an FBA/BIP process still applies if one isn't already in place.

How to Prepare for an MDR Meeting

Come to the MDR meeting with documentation. Bring:

• A copy of the current IEP, with specific attention to behavioral supports and accommodations listed
• Any evidence that services in the IEP were not being delivered (emails, service logs, missed therapy sessions)
• Medical or evaluation records linking the disability to the type of behavior in question
• Any prior FBA findings that identify the function of the behavior

If the district has a pattern of not implementing behavioral supports from the IEP, and your child's behavior escalated as a result, the MDR is your opportunity to make that connection explicit and on the record.

Parents Reaching Out (PRO) offers training on MDR meetings and IEP rights. Disability Rights New Mexico (DRNM) can provide legal support if you believe the MDR process was conducted improperly or if the district is attempting to impose discipline that violates your child's rights.

The New Mexico IEP & 504 Blueprint includes a guide to the disciplinary process under NMAC 6.31.2.13, meeting scripts for MDR meetings, and templates for documenting IEP implementation failures that are relevant to manifestation reviews.
