Oregon Manifestation Determination: What Happens When Your Child Is Suspended

Your child with an IEP just received a 10-day suspension. The school is calling it a disciplinary matter. But under Oregon law, if the behavior that triggered the suspension is connected to your child's disability — or was caused by the district's own failure to implement the IEP — the school cannot simply remove your child and call it done. They have specific legal obligations, and most Oregon parents are not told what those obligations are until it is too late.

What Triggers a Manifestation Determination in Oregon

A Manifestation Determination Review (MDR) is required under OAR 581-015-2420 any time a school district proposes to:

• Suspend a student with an IEP for more than 10 consecutive school days
• Remove a student in a pattern of shorter suspensions that collectively amounts to more than 10 school days in a school year

Both scenarios constitute a "change of educational placement" under Oregon and federal law. Once that threshold is crossed, the district must hold an MDR within 10 school days of the decision to remove.

Oregon follows the IDEA framework closely here. The critical statutory trigger is the 10-school-day mark — not 10 calendar days. Weekends and holidays do not count. If a district suspends your child for 5 days in October and 6 days in January for behaviors that look similar, the cumulative pattern may also trigger review even though no single suspension exceeded 10 days.

Who Attends and What the Team Must Decide

The MDR team consists of the IEP team — meaning the parent, relevant school staff, and the district representative — plus any relevant members determined by the parent and district. The team reviews:

1. All relevant information in the student's file, including the IEP, any teacher observations, and relevant evaluation data
2. The specific conduct that led to the discipline decision

The team must answer two questions:

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

Question 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. The district cannot proceed with expulsion, and must return the student to their placement unless the parent and district agree otherwise.

What Must Happen After a Manifestation Finding in Oregon

When the team determines the behavior is a manifestation, three things must happen under Oregon law:

The district must conduct a Functional Behavioral Assessment (FBA) if one has not already been conducted. An FBA is a structured analysis of why the behavior is occurring — the function the behavior serves for the child. Under OAR 581-015-2240, the assessment must consider the events, conditions, and environmental factors that lead to and maintain the behavior.

The district must implement a Behavior Intervention Plan (BIP) or review and revise an existing BIP. The plan must address the behaviors documented in the FBA and include positive behavioral supports and strategies, not just punitive consequences.

The student must be returned to their placement from which they were removed, unless the parent and district jointly agree to a change of placement through the IEP process.

What Happens If the District Says the Behavior Was NOT a Manifestation

If the team concludes the behavior was not a manifestation, the district may apply the same disciplinary procedures it would apply to a student without a disability. However, even during expulsion proceedings, the district must continue to provide educational services so the student can continue to participate in the general curriculum and progress toward IEP goals.

Parents who disagree with a not-a-manifestation finding have the right to appeal through the dispute resolution process — including requesting an expedited due process hearing. During a stay put challenge, the student remains in their interim alternative educational setting, not their home, while the case is pending.

Common Problems in Oregon Manifestation Determinations

The district pre-decides the outcome. MDR meetings can feel procedurally correct while being substantively predetermined. The district assembles the team, the meeting follows the script, and the conclusion is no manifestation — regardless of the actual evidence. If you believe the outcome was predetermined, document your objection clearly in writing at the meeting and request Prior Written Notice of the determination.

The FBA and BIP are inadequate. Many districts satisfy the technical requirement of conducting an FBA by producing a minimal document that does not identify the function of the behavior or propose meaningful supports. A one-paragraph FBA that recommends "redirection" is not compliant. Push for specificity: what is the hypothesized function, what antecedent conditions trigger the behavior, and what proactive strategies will prevent recurrence?

The IEP was not being implemented. Oregon districts frequently suspend students for behaviors that emerge directly from the district's own failure to deliver services documented in the IEP. If your child's IEP called for 30-minute daily sessions with a behavioral specialist and those sessions were not occurring, that failure is directly relevant to Question 2 at the MDR. Document service delivery gaps with attendance records, service logs, and teacher communications before the MDR occurs.

Shortened school days are used as informal suspension. Some Oregon districts respond to behavioral challenges by informally sending students home early rather than going through formal suspension procedures. This practice is illegal — it is both a denial of FAPE and a violation of Senate Bill 819's protections around abbreviated school days. If your child is being sent home early repeatedly, that pattern may also trigger the cumulative removal analysis that requires an MDR.

Building Your Case Before the MDR

If you receive notice that a long-term suspension or expulsion is being considered, act immediately:

1. Request in writing the specific behavioral records the district intends to review
2. Request a copy of the current IEP and all service delivery logs for the year
3. Document in writing any services that were not delivered as specified in the IEP
4. Attend the MDR with your own notes summarizing how the behavior relates to your child's documented disability
