Functional Behavior Assessment in Mississippi: What Parents Need to Know

Your child is being disciplined constantly, suspended informally, or sent home for behavior. The school says it's a discipline problem. You believe the behavior is tied to your child's disability. Before any suspension beyond 10 days, before any change in placement, Mississippi law requires the school to conduct a Functional Behavior Assessment — and most parents don't know what that means or how to use it.

A Functional Behavior Assessment (FBA) is a structured investigation into why a behavior is occurring. It identifies the antecedents (what triggers the behavior), the behavior itself, and the consequences that follow — the events that are inadvertently reinforcing the behavior. An FBA is not a punishment review. It is a data-gathering process that should lead directly to a Behavior Intervention Plan (BIP) that actually addresses the root cause.

When Mississippi Schools Must Conduct an FBA

Mississippi's State Board Policy 74.19 (Volume IV: Discipline) specifies the circumstances that trigger a required FBA for students with IEPs:

1. Before a disciplinary change of placement When a school proposes to remove a student with an IEP for more than 10 consecutive school days (or a pattern of shorter removals that add up to more than 10 days), a Manifestation Determination Review must occur. If the MDR finds the behavior is a manifestation of the disability, the IEP team is required to conduct an FBA (if one hasn't already been done) and develop or update a BIP.

2. When an existing BIP is not working If a student has a BIP and continues to experience behavioral crises, the IEP team should reconvene to review the FBA and revise the plan. An "Insufficient Progress" code on a BIP goal should trigger this review.

3. As part of a comprehensive evaluation When a student is referred for evaluation due to behavioral or emotional concerns, an FBA should be part of the assessment battery.

You can also request an FBA at any time as part of a re-evaluation request. If your child's behavior is escalating and the school hasn't initiated this process, put the request in writing.

What a Proper FBA Includes

A legally adequate FBA in Mississippi is not a brief anecdotal review by a teacher. It should include:

• Direct observation of the student in multiple settings (classroom, lunch, specials) by a qualified professional
• Antecedent analysis — what consistently happens before the behavior occurs (a difficult task presented, a transition, a sensory trigger)
• Data on frequency, duration, and intensity of the behavior
• Interviews with teachers, parents, and the student (when age-appropriate)
• Review of existing records — previous evaluations, disciplinary logs, progress reports
• Hypothesis about the function — what the behavior is accomplishing for the child (escape from task, attention-seeking, communication of unmet need, sensory regulation)

The function hypothesis drives everything. A child who throws materials to escape a difficult reading task needs a completely different BIP than a child who throws materials to get peer attention. An FBA that doesn't establish function is incomplete.

The Behavior Intervention Plan That Must Follow

Once the FBA identifies the function of the behavior, the BIP must address it directly. In Mississippi, a legally sound BIP includes:

• A precise description of the target behavior (specific enough to measure)
• The identified function of the behavior
• Antecedent strategies to prevent the behavior from being triggered
• Replacement behaviors the student will be taught (functionally equivalent alternatives that meet the same underlying need)
• Consequence strategies — what adults will do when the behavior occurs and when the replacement behavior occurs
• A plan for teaching and reinforcing the replacement behavior
• Progress monitoring: how the BIP's effectiveness will be measured and reported

A BIP that consists of "redirect student when behavior occurs" is not adequate. Redirection is not a function-based intervention.

The "Constructive Suspension" Problem and FBAs

Mississippi's research documents a specific pattern: schools repeatedly call parents to pick up behaviorally challenged children early without formally logging the event as a suspension. This avoids the formal count of days that triggers an MDR and FBA requirement.

If the school is calling you regularly to remove your child from the building, start documenting every incident — date, time, reason given, duration. These informal removals can constitute a de facto change of placement even without formal suspension paperwork. Consult Mississippi Manifestation Determination for how to use this documentation.

Rural Mississippi and Behavioral Assessment

Over half of Mississippi's population lives in rural areas where Board Certified Behavior Analysts (BCBAs) and school psychologists with behavior assessment training are scarce. Mississippi has designated Special Education as a Critical Shortage Subject area, with 599 unfilled special education positions statewide in 2025-2026.

This shortage is not a legal excuse for inadequate assessments. Federal law is explicit: districts cannot cite staffing shortages as a reason to deny required services. However, it does mean you may be dealing with a less experienced evaluator or an assessment conducted via teletherapy platforms. If the FBA feels shallow — one observation session, no parent interview, a generic report — you have grounds to question the adequacy of the evaluation and potentially request an Independent Educational Evaluation.

The Mississippi IEP & 504 Blueprint includes a checklist for auditing an FBA report and the specific language for requesting a more thorough assessment if the initial one falls short.
