Functional Behavior Assessment in New York: When It's Required and What It Must Include

Your child is being suspended repeatedly, removed from class, or the school wants to discuss a "behavior plan." Before they put anything in writing, they should be conducting a Functional Behavior Assessment. Most New York parents don't know this is a requirement — or that "behavior plan" language without a proper FBA is often meaningless on paper and useless in practice.

What a Functional Behavior Assessment Is

A Functional Behavior Assessment (FBA) is a systematic process for identifying the purpose — the "function" — of a specific behavior. Behaviors occur because they serve a need: avoiding something difficult (escape), getting attention, accessing a preferred item or activity, or seeking sensory input. An FBA determines which function is driving a particular behavior so that interventions can address the root cause rather than just attempting to suppress the behavior.

A proper FBA includes:

• Indirect assessment: Interviews with parents, teachers, and the student about when and where the behavior occurs
• Direct observation: Structured observation in the actual environments where the behavior happens, with data collection using tools like ABC (Antecedent-Behavior-Consequence) recording
• Record review: Behavior logs, incident reports, prior evaluations, and academic records
• Hypothesis statement: A testable statement about the function driving the behavior
• Environmental analysis: Identification of setting events and triggers

The output of an FBA is a clear, data-supported hypothesis about why the behavior occurs. That hypothesis then drives the Behavior Intervention Plan (BIP) — the actual strategy for addressing it.

When New York Requires an FBA

New York's Part 200 regulations specify circumstances when an FBA is required:

During initial evaluation: If behavior is an area of suspected disability or concern, a behavioral assessment must be part of the comprehensive evaluation (Part 200.4(b)(1)).

After a manifestation determination: Under Part 201 (New York's discipline procedures), when a student with a disability is subject to a change in placement because of a disciplinary removal, and the behavior is determined to be a manifestation of the disability, the district must conduct or review an FBA and develop or revise the BIP as part of the manifestation determination process (Part 201.11(b)).

When behavior impedes learning: If a student's behavior impedes their own learning or that of others, the CSE must consider strategies — including positive behavioral interventions — to address that behavior (Part 200.4(d)(2)(v)). While Part 200 does not explicitly require an FBA in all such cases, it is the professional standard for conducting this consideration meaningfully.

When behavior is escalating: If a student has been subjected to a series of short-term removals or suspensions that total more than 10 school days in a year, IDEA and Part 201 protections are triggered and an FBA is required.

New York City-Specific Considerations

In NYC, the DOE has issued guidance requiring FBAs as part of the CSE process for students whose behavior is a primary concern. However, the quality of FBAs in NYC varies widely. Many schools complete brief checklists that do not include direct observation data, describe behaviors vaguely ("acting out," "non-compliant"), or skip the hypothesis statement entirely. This type of document does not constitute a valid FBA.

NYC also has Positive Behavioral Interventions and Supports (PBIS) coaches and behavior specialists within districts. If an FBA has not been conducted or is inadequate, you can request one explicitly — not just a "behavioral observation" — and ask that a behavior specialist or Board Certified Behavior Analyst (BCBA) be involved. The district does not have to use a BCBA, but requesting one puts the quality standard on the table.

How to Request an FBA

You can request an FBA as part of an initial evaluation request or as a stand-alone request when behavior is the primary concern. Write to the CSE chairperson or special education director:

"I am requesting a Functional Behavior Assessment for [child's name] as part of the special education evaluation process, pursuant to Part 200.4(b)(1). I am also requesting that direct observation be conducted in [classroom/lunch/specific setting] and that a behavior specialist be involved in the assessment."

If an FBA was completed but you believe it is inadequate, you can request an Independent Educational Evaluation (IEE) of the FBA at public expense under Part 200.5(g). An outside behavior specialist can complete a thorough FBA and provide a written report the CSE must consider.

What a Good BIP Looks Like

The FBA should directly drive a Behavior Intervention Plan (BIP) that includes:

• Target behavior definition: Specific, observable, measurable description (not "non-compliant" but "leaves assigned seat without permission more than three times per 45-minute period")
• Hypothesis: The function identified through the FBA (e.g., "escape from difficult reading tasks")
• Antecedent strategies: Changes to the environment or instruction to reduce triggers (e.g., pre-teaching vocabulary before reading tasks, providing a brief preview of work)
• Replacement behavior: A functionally equivalent, appropriate behavior the student is taught (e.g., requesting a break using a card instead of bolting)
• Consequence strategies: How adults respond consistently when the target behavior occurs and when the replacement behavior occurs
• Reinforcement plan: What motivates the specific student; individualized, not generic
• Data collection method: How the behavior will be measured and how often progress will be reviewed
• Crisis plan: If relevant, what to do if the behavior escalates to a safety concern

A BIP without all of these components is a set of generic rules, not a behavior intervention plan. It will not work, and when it doesn't work, the school will recommend a more restrictive placement. A well-executed FBA and BIP is often what prevents that escalation.

FBA and Placement Decisions

In New York, when a student is being considered for a more restrictive placement — a 12:1:1 classroom, District 75, or a non-public school — because of behavior, the FBA becomes critical. If the FBA has not been done or is poor quality, the placement decision is based on incomplete data. You can challenge a restrictive placement recommendation by arguing that the behavior has not been properly assessed and that less restrictive alternatives with a real BIP have not been tried.

The New York IEP & 504 Blueprint includes an FBA quality checklist, a guide to reviewing BIPs at the CSE meeting, and templates for requesting behavioral assessments and independent behavioral evaluations.
