Minnesota Functional Behavior Assessment and Behavior Intervention Plan: A Parent's Guide

When a student's behavior is getting them suspended, sent home early, or removed from the classroom repeatedly, the school's response is often reactive — calling the parent, writing incident reports, issuing consequences. What Minnesota law requires in many of these situations is something more systematic: a Functional Behavior Assessment.

An FBA is not a punishment. It is an analysis. Before a school can design an effective behavioral support plan for a student, it needs to understand what function the behavior serves — why the student is doing what they're doing. Skip the analysis, and the intervention almost always fails.

What Is a Functional Behavior Assessment?

A Functional Behavior Assessment (FBA) is a structured, data-driven process for identifying the relationship between a student's problem behavior and the environmental factors that trigger and maintain it. It answers the question: what is the behavior communicating, and what does the student get (or avoid) by engaging in it?

Every behavior serves one or more functions. The most common functional categories are:

• Escape/avoidance: The student engages in problem behavior to get out of a difficult task, an uncomfortable social situation, a sensory environment, or a particular class or setting.
• Attention: The behavior gets the student attention from peers, teachers, or other adults — positive or negative.
• Access to tangibles or activities: The behavior results in getting something the student wants — a preferred object, activity, or sensory input.
• Sensory stimulation: The behavior itself provides sensory feedback that the student finds reinforcing.

A behavior intervention that addresses the wrong function will not work. A student who elopes from the classroom to escape a difficult reading assignment does not need more reading consequences — they need reading instruction that matches their actual level, and possibly a communication strategy for requesting breaks appropriately.

When Is an FBA Required in Minnesota?

Under federal IDEA and Minnesota Rules Chapter 3525, an FBA is explicitly required in two situations:

1. Manifestation Determination Review (MDR): If a school proposes a disciplinary removal that constitutes a change of placement — a suspension exceeding 10 consecutive school days, or a pattern of short-term suspensions totaling more than 10 days in a school year with a similar pattern and similar circumstances — the IEP team must conduct an MDR. If the team determines that the behavior was a manifestation of the disability, the school must conduct an FBA and implement or revise a Behavior Intervention Plan.

2. When behavior is impeding learning: Under IDEA, when a student's behavior impedes their own learning or the learning of others, the IEP team is required to consider positive behavioral interventions and supports — which in practice means the team should be considering whether an FBA and BIP are warranted.

Beyond these two explicit triggers, parents can request an FBA at any time as part of a comprehensive evaluation or as a standalone assessment. The request should be made in writing. The district must respond with a Prior Written Notice (PWN) under Minn. R. 3525.3600, either agreeing to conduct the FBA or explaining in writing why it is refusing.

What a Complete FBA Includes

A legally sufficient FBA for a Minnesota school should include:

Direct observation: Observation of the student in the settings where the problem behavior occurs, by a qualified assessor (often a behavior specialist, school psychologist, or BCBA). Observations should occur across multiple settings and times of day.

Antecedent analysis: Documentation of what consistently precedes the problem behavior — time of day, setting, activity, presence or absence of specific people, sensory conditions.

Behavior description: An operational definition of the behavior that is specific enough for any observer to identify it consistently. "Aggression" is too vague. "Student throws objects weighing less than 2 pounds toward staff or peers, occurring within 5 minutes of being assigned a writing task" is operational.

Consequence analysis: What happens immediately after the behavior — what response does the student receive from staff and peers? Does the behavior result in the student getting what they were seeking (escape, attention, access, sensory)?

Interviews: Structured interviews with teachers, parents, and the student (when developmentally appropriate) about the contexts and triggers for the behavior.

Hypothesis statement: A written hypothesis — not a punishment determination — identifying the most likely function of the behavior and the specific environmental conditions that predict it.

An FBA conducted by an observer who spends 20 minutes in one classroom is unlikely to produce a valid hypothesis. If the school's FBA was conducted without direct observation, without a clear antecedent-behavior-consequence analysis, or without parent input, it is worth questioning whether the FBA was adequate — and whether an Independent Educational Evaluation of behavioral functioning at public expense is warranted.

What a Behavior Intervention Plan Must Contain

A Behavior Intervention Plan (BIP) is the action document that follows from an FBA. It must be incorporated into the IEP (or attached as an IEP addendum) and must specify services that are legally binding.

A compliant BIP should include:

• Target behavior: The specific behavior being addressed, using the same operational definition from the FBA
• Hypothesis statement: The identified function(s) of the behavior
• Antecedent modifications: Environmental changes the school will make to reduce the likelihood of the behavior occurring — modifying the task, the setting, the sensory conditions, the level of adult proximity, or the schedule
• Replacement behavior instruction: The specific, functionally equivalent alternative behavior the student is being taught, and the explicit instruction plan for teaching it
• Reinforcement plan: How the school will reinforce the replacement behavior and other positive behaviors; what schedule and what reinforcers are specified
• Response procedures: What staff will do when the target behavior occurs — consistent, written, agreed-upon procedures that do not inadvertently reinforce the behavior
• Data collection plan: How the school will track the frequency, duration, or intensity of the target behavior and the replacement behavior over time
• Crisis response plan: If the behavior can escalate to physical danger, what the crisis response looks like, who is responsible, and when parents will be contacted

A BIP that is written and then filed away without staff training or consistent implementation is not FAPE. If the BIP exists but staff are not following it — or if the plan has not been updated in response to data showing it isn't working — the school may be out of compliance.

The Manifestation Determination in Minnesota

If your child with an IEP or 504 Plan faces a disciplinary removal of more than 10 school days, or a pattern of shorter removals totaling more than 10 days in a year with similar circumstances, this constitutes a "change of placement" that triggers a Manifestation Determination Review (MDR).

The MDR must be held before the change of placement takes effect (or within 10 school days of the disciplinary decision). The IEP team — including the parent — must answer two questions:

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

If the answer to either question is "yes," the behavior is a manifestation of the disability. The school cannot proceed with a long-term suspension or expulsion for that behavior. Instead, it must conduct or revise the FBA and implement or revise the BIP, and return the student to their educational placement.

If the MDR team determines the behavior was not a manifestation — and you disagree — you have the right to object and pursue the same dispute resolution options available for any IEP disagreement: requesting a Conciliation Conference (Minnesota's unique pre-dispute step under Minn. Stat. § 125A.091 Subd. 7), filing a state complaint under Minn. R. 3525.4770, or requesting due process under Minn. Stat. § 125A.091 Subd. 13.

Requesting an FBA When the School Won't Initiate One

If your child is experiencing repeated behavioral incidents and the school has not conducted an FBA, put your request in writing. State that you are requesting a Functional Behavior Assessment as part of your child's comprehensive special education evaluation because challenging behavior is impeding their access to educational programming. The district must respond in writing with a PWN, and if it refuses, you have 14 calendar days to object — triggering the Conciliation Conference process.

Private advocates in Minnesota charge $100–300 per hour for behavioral consultation work. A well-conducted FBA and BIP by a district-employed behavior specialist costs the family nothing — but you may need to push for it.

The Minnesota IEP & 504 Blueprint includes an FBA request letter template, a BIP compliance checklist, a guide to participating in the MDR process, and the exact 14-day written objection language for when the school refuses to conduct a behavioral evaluation.
