Discipline Rights for California Special Education Students: Suspension, MDR, and FBA
Your child was suspended. Or threatened with expulsion. And they have an IEP. The school is treating this as a standard discipline matter, but it isn't — not legally. California has strong, specific protections for students with disabilities facing school discipline, and most parents don't know them until after something has gone wrong.
Here's what the law requires, and what you can do to enforce it.
The "10-Day Rule": California's Critical Threshold
For a student with an IEP or a 504 plan, every suspension matters — not just individually, but cumulatively. California law follows the IDEA framework: a student with a disability cannot be suspended for more than 10 school days in an academic year if those removals constitute a "pattern" of exclusion.
A pattern exists when:
- The suspensions are for similar behaviors
- The suspensions are close in time to each other
- The length of each suspension and the total time removed are significant
Crossing the 10-day threshold — either through a single continuous suspension or a series of shorter ones that constitute a pattern — triggers what the law calls a change of placement. Once a change of placement has occurred, additional procedural protections kick in automatically.
California Education Code § 48900.5 adds another layer: suspension should only be used when other means of correction have failed. That means the district is supposed to try counseling, restorative justice, positive behavioral interventions, or other supports before suspending a student — particularly a student with a disability whose behavior may be disability-related.
What a Manifestation Determination Review (MDR) Is and When It's Required
When a suspension or series of suspensions constitutes a change of placement, the district must convene a Manifestation Determination Review (MDR) within 10 school days.
The MDR is a formal meeting. The team — which includes the parent, relevant IEP team members, and district representatives with knowledge of the student — must answer two questions:
- Was the conduct in question caused by, or did it have a direct and substantial relationship to, the child's disability?
- Was the conduct the direct result of the district's failure to implement the IEP?
If the answer to either question is yes, the conduct is a manifestation of the disability. The student cannot be expelled. The team must conduct a functional behavior assessment (if one hasn't already been done), implement a behavioral intervention plan (or review and modify an existing one), and return the student to the placement they were in — unless the parent and district agree to a different placement as part of the BIP review.
If the answer to both questions is no, the district can proceed with expulsion — but even then, the student must continue to receive educational services during the expulsion period, and services must allow the student to continue to participate in the general education curriculum and progress toward IEP goals.
How Districts Try to Avoid a Manifestation Finding — and How to Counter It
Districts have financial and operational incentives to find that behavior was not a manifestation of the student's disability. A non-manifestation finding allows them to proceed with expulsion and potentially remove a difficult-to-serve student from their rolls.
Common district tactics to watch for:
Claiming the behavior is not in the disability's "expected range." For example: an autistic student who hits a teacher when overwhelmed. The district may argue the autism causes social communication challenges, but not aggression — so this behavior isn't related to the autism. This argument misunderstands autism and ignores what the research says about sensory overload, emotional dysregulation, and fight-or-flight responses in autistic individuals.
Claiming the IEP was being implemented. The district may argue that because services were theoretically on paper, the failure-to-implement prong doesn't apply. Your counter: request service logs. If the services weren't actually delivered at the frequency and duration specified in the IEP, the IEP was not being implemented — and the district's own records will show it.
Moving quickly before parents can organize. The 10-day MDR timeline is tight. If you receive notice of a suspension, request immediately in writing that the MDR be scheduled, and confirm your intent to attend. Ask for the meeting agenda and any behavioral data in advance.

Functional Behavior Assessments (FBA) in California
A Functional Behavior Assessment is an analysis of why a student is engaging in a particular behavior. It identifies the antecedents (what happens before the behavior), the behavior itself, and the consequences (what the student gets or avoids through the behavior). Understanding the function of a behavior — escape, attention-seeking, sensory input, access to preferred items — is essential to designing an intervention that actually works.
In California, an FBA is required when:
- The student's behavior is impeding their own learning or the learning of others, and the IEP team hasn't yet addressed it with an FBA and BIP
- A change of placement due to discipline has occurred and no FBA exists
You can also request an FBA proactively at any time through a written request. California Education Code § 56321 applies: the district must provide an assessment plan within 15 calendar days of your written request, and complete the assessment within 60 calendar days of your consent signature.
An effective FBA is not a one-page checklist. It involves observation across settings, interviews with teachers, parents, and if appropriate the student, and data collection over time. If the district's FBA is superficial — a brief office observation and a checkbox form — you can challenge it or request an IEE.
Behavior Intervention Plans (BIP)
Once an FBA is complete, the IEP team develops a Behavior Intervention Plan — a document that specifies:
- The target behaviors to reduce
- The replacement behaviors to teach (functionally equivalent alternatives)
- The environmental modifications that will be made to reduce triggers
- Specific interventions and supports the team will use
- How progress will be measured
- Crisis protocols if needed
A BIP must be individualized. Generic statements like "student will be redirected when off-task" are not a BIP. A proper BIP describes specific strategies, who is responsible for implementing each one, and how the team will know if it's working.
If your child's IEP includes a BIP and the district isn't implementing it consistently, that is a compliance violation — the failure to implement the IEP. File a CDE compliance complaint documenting the implementation gaps, and request service logs to verify.
What to Do When Your Child Faces Discipline in a California School
Immediately upon receiving notice of a suspension exceeding 5 days, or any threat of expulsion:
- Request the MDR in writing and confirm your intent to participate as an equal team member.
- Request all behavioral data, incident reports, and IEP implementation records under California Education Code § 56504, which requires the district to provide records within 5 business days.
- Contact the district in writing asking them to identify what behavioral supports were in place and what was done to implement the IEP before resorting to suspension.
- Note whether an FBA and BIP were in the IEP — if not, and if behavioral needs were documented, the absence of an FBA may itself be a FAPE violation.
