Manifestation Determination in Tennessee: What Happens When Your Child Faces Discipline

Your child has an IEP and now faces a serious disciplinary action — a long suspension or possible expulsion. The school schedules a "Manifestation Determination Review." You're not sure what this meeting is supposed to accomplish, who gets to make the decision, or what protections your child actually has.

Here is a clear account of how this process works under Tennessee law and what you can do when it goes wrong.

What a Manifestation Determination Review Is

A Manifestation Determination Review (MDR) is a meeting of the IEP team — including you as the parent — that must occur within 10 school days of any disciplinary action that constitutes a change of placement for a student with an IEP.

The team's job is to answer two questions:

1. Was the conduct caused by, or did it have a direct and substantial relationship to, the child's disability?
2. Was the conduct the direct result of the school's failure to implement the IEP?

If the answer to either question is yes, the behavior is a manifestation of the disability. If the answer to both is no, the school may discipline the student in generally the same way they would discipline a student without a disability — but even then, specific IDEA protections continue to apply.

When an MDR Is Required

An MDR is required whenever a student with an IEP faces a removal that:

• Exceeds 10 consecutive school days, OR
• Constitutes a "pattern" — meaning a series of shorter removals that collectively add up to significant missed instruction and are comparable in purpose, timing, or circumstance

The 10-school-day trigger is a hard rule. If a student has been suspended for 10 consecutive school days, the MDR must happen within the next 10 school days — not within 10 calendar days, but 10 school days. Days the school is not in session do not count.

One important caveat: a single removal of 1–9 school days does not trigger an MDR. But if the district imposes multiple short suspensions over the course of the year and those suspensions collectively constitute a pattern of exclusion, an MDR is required regardless of whether any single suspension hit the threshold.

The Two-Question Standard

Question 1: Direct and substantial relationship to the disability. The team must look at the student's specific disability and evaluate whether the conduct in question is directly and substantially related to it. This is a lower standard than "caused by." Direct and substantial relationship does not require proof that the disability was the sole cause — only that there was a real and significant connection between the disability and the behavior.

For example: a student with Emotional Disturbance who shoves a peer during a period of acute emotional dysregulation. The disability is Emotional Disturbance. The conduct (physical aggression during dysregulation) has a direct and substantial relationship to the disability.

A student with a Specific Learning Disability who fights on the bus over a completely unrelated conflict probably does not have that fight connected to their learning disability in any direct way.

Question 2: Did the school fail to implement the IEP? If the IEP required a behavioral aide, de-escalation protocols, or regular check-ins that weren't being provided, and the failure of those services contributed to the behavioral incident, the conduct is a manifestation — even if the disability itself doesn't have a direct relationship to the specific behavior.

This second prong exists because the school's legal obligation is to actually implement what they've written. A beautifully written BIP that no one follows does not protect the district at an MDR.

If the Behavior IS a Manifestation

When the team finds a manifestation, the consequences are specific:

• The school cannot expel the student for the conduct (with one narrow exception)
• The student must be returned to the placement in which the behavior occurred, unless you and the school agree to a different placement through the IEP process
• The team must either conduct a Functional Behavior Assessment (if one hasn't been done) or review and revise the existing BIP

The student may still receive a short-term alternative placement — but only up to 45 school days in an Interim Alternative Educational Setting (IAES), and only for specific offenses involving weapons, controlled substances, or the infliction of serious bodily injury on someone at school. For all other conduct, a manifestation finding means the student returns to their placement and the school addresses the behavior through the IEP.

If the Behavior Is NOT Found to Be a Manifestation

The team determines the behavior was not related to the disability and was not caused by IEP non-implementation. The school may then discipline the student the same way it would discipline a non-disabled student for the same offense — including expulsion proceedings.

But two protections remain even here:

1. The student must continue to receive educational services that allow them to participate in the general education curriculum and make progress toward their IEP goals — even during a long-term suspension or expulsion
2. The student continues to receive the services specified in the IEP during any placement in an IAES

Unlike non-disabled students, a student with an IEP can never simply be excluded from education. Services continue regardless of the disciplinary outcome.

The Role of Parents at the MDR

You are a required member of the MDR team, not an observer. You have an equal vote. However, in practice, school teams often present a pre-determined conclusion, and the meeting is structured to move through the two questions quickly.

Come prepared. Before the meeting:

• Request copies of all records related to the incident, including any incident reports, teacher accounts, and witness statements
• Review the current IEP — particularly the BIP and all behavioral supports and services
• Note whether all services listed in the IEP were actually being delivered
• Gather any documentation of prior incidents that demonstrate a pattern, especially if the school previously identified behavioral concerns and failed to act on them

If you believe the behavior was a manifestation and the team disagrees, you can exercise your right to challenge the MDR outcome by requesting mediation or filing for due process. The student's current placement must be maintained (stay put) while that challenge is pending, unless the conduct involved weapons, drugs, or serious bodily injury.

Tennessee's "Informal Removal" Problem

A 2025 report by the Tennessee Comptroller's Office of Research and Education Accountability documented a troubling pattern across Tennessee schools: administrators calling parents to pick up students with behavioral disabilities rather than issuing formal suspensions. These "informal removals" are not recorded in disciplinary systems and therefore never trigger the 10-day threshold or an MDR.

If your child has been sent home repeatedly through informal parent calls — rather than formal suspensions — those removals may still constitute a pattern triggering your child's procedural rights. Begin documenting every instance with dates, times, and who called. If the school is using informal removals to avoid the MDR process, that is a procedural violation of IDEA.

The Bottom Line

A Manifestation Determination Review is one of the highest-stakes meetings in special education. The outcome determines whether your child can be expelled and whether they return to their current program. Going in without understanding the two-question standard, your right to dispute the outcome, or the pattern-of-removal doctrine puts your child at real risk.

The Tennessee IEP & 504 Blueprint includes a section on disciplinary protections, the stay put rule, and how to document patterns of informal removal — the tools you need before the 10-day window closes.
