Manifestation Determination in Iowa: What Happens When Your Child Faces Expulsion

Your child with an IEP or 504 plan just got suspended. The principal is talking about moving toward long-term suspension or expulsion. Before any of that can happen, Iowa law requires the school to answer a specific legal question: Was the behavior caused by the child's disability?

That question is answered at a Manifestation Determination Review (MDR).

What Triggers an MDR in Iowa

Under Iowa Administrative Code 281-41.530, a Manifestation Determination Review is required any time a school proposes to:

• Remove a student with a disability for more than 10 consecutive school days
• Impose a series of shorter removals that total more than 10 school days in a school year and constitute a change of placement

The 10-day threshold is the critical number. Once cumulative suspensions in a school year cross 10 school days and the pattern of removals constitutes a change of placement, the MDR is mandatory. The school cannot proceed with expulsion, alternative school placement, or any other disciplinary change of placement until the MDR is complete.

The 10-Day Deadline

The MDR must occur within 10 school days of the decision to change placement. This is a hard deadline. If the school moves toward expulsion proceedings without completing the MDR within that window, they have committed a procedural violation under IDEA that you can document and escalate through a state complaint.

At the MDR, the IEP team convenes. This is not a disciplinary hearing — it is a legal determination. The team members include the parent, at least one general education teacher, an LEA representative, and relevant AEA staff (particularly if a behavioral evaluation is involved).

The Two Questions the Team Must Answer

The MDR team must determine both of the following:

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

Question 2: Was the conduct a direct result of the local educational agency's failure to implement the child's IEP?

If the answer to either question is yes, the behavior is a manifestation of the disability. The school cannot proceed with the expulsion.

What "Direct and Substantial Relationship" Means

The team is not asking whether the disability made the behavior possible — almost any behavior by any person could be connected to some characteristic of ADHD, autism, or emotional disturbance if the standard were that low. The standard is whether the disability directly and substantially caused the specific conduct.

For example: A student with ADHD who impulsively shoves another student in the hallway during a transition — a documented trigger for impulsive behavior in their evaluation — has a much stronger manifestation argument than a student who carefully planned a fight. A student with autism who has a meltdown triggered by an unplanned fire drill — a known sensory vulnerability documented in their BIP — has a strong manifestation case.

The IEP team must review the child's current IEP, existing behavioral data, the evaluation reports, and the specific circumstances of the incident when making this determination. They cannot simply vote based on their intuition.

What "Failure to Implement the IEP" Means

The second question is separate and equally important. If the school or AEA failed to deliver services written in the IEP — missed therapy sessions, unapplied behavior intervention plan strategies, failure to provide documented accommodations — and that failure contributed to the behavioral incident, the behavior is automatically a manifestation regardless of whether the disability itself caused it.

This is why it matters that you document service delivery and track IEP implementation. If your child's BIP required sensory breaks every 90 minutes and the classroom teacher stopped providing them, and the behavioral incident occurred after hours without breaks, that implementation failure is directly relevant.

If the Behavior Is a Manifestation

If the MDR team determines the behavior was a manifestation of the disability, the school must:

• Return the student to the placement from which they were removed (unless you and the school agree to a different placement as part of an IEP revision)
• Conduct a Functional Behavior Assessment if one has not already been done
• Develop or revise the Behavior Intervention Plan

The student cannot be expelled or placed in an alternative setting solely because of the conduct, with three exceptions.

The Three Exceptions: Special Circumstances

Even when behavior is a manifestation of disability, Iowa schools can move the student to an Interim Alternative Educational Setting (IAES) for up to 45 school days if the conduct involved:

1. Carrying or possessing a weapon at school or a school function
2. Knowingly possessing, using, selling, or soliciting illegal drugs at school or a school function
3. Inflicting serious bodily injury on another person at school or a school function

The IAES must still provide FAPE — the student must continue to receive special education services during the 45-day period, just in a different setting.

If the Behavior Is Not a Manifestation

If the team determines the behavior was NOT a manifestation of the disability, the district can proceed with the same disciplinary procedures that would apply to students without disabilities. However, even then:

• The student continues to receive FAPE during the removal period
• Educational services must be provided so the student can continue to make progress toward their IEP goals
• Special education services cannot simply stop

Protecting Your Rights at the MDR

As a parent, you are a full member of the MDR team. You have the right to:

• Request a copy of all documentation the team plans to use before the meeting
• Bring an advocate or legal representative (see iowa-special-education-advocate)
• Disagree with the team's determination in writing
• File for expedited due process if you believe the manifestation determination was incorrect

Iowa is a one-party consent state (Iowa Code § 808B.2), so you can legally record the MDR meeting without notifying the school, as long as you are a participant.

If you believe the MDR outcome was wrong, you can request an expedited due process hearing through the Iowa Department of Education. The hearing officer can review the determination and order the student returned to their placement while the case proceeds.

For the behavioral assessment process that should inform the MDR, see Iowa functional behavior assessment. For the broader discipline and due process framework, see Iowa due process hearing.

An MDR is one of the highest-stakes meetings Iowa parents face. The Iowa IEP & 504 Blueprint covers the full MDR process under IAC 281-41.530, including the documentation checklist, parent arguments for manifestation, and what to do immediately if the team gets it wrong.
