Functional Behavior Assessment in DC Schools: When to Request One and What It Must Include
A Functional Behavior Assessment (FBA) is the foundation of any effective behavioral support in a DC school. Without one, behavioral interventions are guesswork — strategies that might work for one function of a behavior will backfire if the behavior actually serves a different function. Many DC schools skip FBAs or conduct minimal versions that don't produce useful information. Knowing what a proper FBA requires, when you can demand one, and what to do if the school's is inadequate gives you real leverage.
What an FBA Is and Why the Function Matters
An FBA identifies the function — the "why" — behind a student's challenging behavior. The same observable behavior (a student becoming physically aggressive, a student refusing to complete work, a student walking out of class) can serve entirely different functions:
- Escape/avoidance: The behavior removes the student from a non-preferred task, setting, or social interaction
- Attention: The behavior produces attention from adults or peers (positive or negative)
- Tangible access: The behavior produces a desired item or activity
- Sensory regulation: The behavior provides or reduces sensory input
An intervention effective for an escape-motivated behavior (making the task more accessible) will reinforce an attention-motivated behavior (removing the student from the group gives them more adult attention). The FBA identifies the function so that interventions target the right mechanism.
DC schools that write BIPs without a proper FBA — using checklists, brief teacher interviews, or assumptions about the student's motivation — produce plans that frequently fail. When the plan doesn't work, the problem is usually traced back to a missing or inadequate FBA.
When DC Schools Are Required to Conduct an FBA
Mandatory in discipline contexts: Under IDEA and DC's 5-A DCMR, a school must conduct an FBA and implement a BIP when:
- A student with a disability is placed in an interim alternative educational setting (IAES) for drug, weapon, or serious bodily injury violations
- A student has been suspended for more than 10 cumulative school days (triggering manifestation determination), and no FBA and BIP are currently in place
- The manifestation determination finds that the behavior was a manifestation of the disability, and the school must implement or revise the BIP
Required when behavior impedes learning: IDEA §614(d)(3)(B)(i) requires the IEP team to consider behavioral supports, strategies, and interventions when a student's behavior impedes their own learning or the learning of others. This is a broad mandate — it does not require a disciplinary incident. Recurring off-task behavior, chronic classroom disruption, behavioral patterns documented in teacher notes or office referrals, or behavioral challenges that are preventing access to instruction all fall within this requirement.
You can request an FBA at any IEP meeting as part of the behavioral support discussion. Put the request in writing.
What a Compliant FBA Must Include
A proper FBA is a multi-component assessment process, not a single form. Under professional standards recognized by IDEA's implementation framework:
Direct observation: The evaluator must directly observe the student in the settings where the behavior occurs. This means the classroom, transitions, lunch, and any other relevant environment — not just a brief hallway observation.
Indirect assessment: Structured interviews with teachers, parents, and the student (when appropriate). Rating scales completed by multiple raters across settings. Review of existing data: discipline records, grades, prior evaluations, attendance records.
A-B-C analysis: Systematic documentation of Antecedents (what happens immediately before the behavior), Behavior (specific, observable description of the behavior including topography, frequency, duration, and intensity), and Consequences (what happens immediately after the behavior).
Functional hypothesis: A specific hypothesis about the function the behavior serves for the student, derived from the data collected. The hypothesis should be testable — ideally, there should be data that would confirm or disconfirm it.
An FBA that consists of a single classroom observation form, a one-paragraph teacher interview, and a checkbox list is likely insufficient for any student with a complex behavioral presentation. This kind of minimal FBA is common at both DCPS and charter schools facing capacity constraints.

DC's IEE Rate for Independent FBAs
If you disagree with the school's FBA — because it was incomplete, used inadequate methodology, or produced a functional hypothesis you believe is incorrect — you have the right to request an Independent Educational Evaluation (IEE) at public expense.
DC's 2025-2026 IEE rate schedule caps FBAs at $1,200 for a public-expense independent FBA. If you request an IEE for an FBA, the school must either fund an independent evaluator within this cap or file for due process within a reasonable time to defend the adequacy of its own FBA.
An independent FBA conducted by a Board Certified Behavior Analyst (BCBA) is typically more thorough than a school-conducted FBA, particularly for students with significant behavioral complexity. If the school's intervention plan has been failing and you suspect the function identification is wrong, an independent FBA is the most direct way to get a fresh analysis.
Requesting an FBA from DCPS or a Charter School
To request an FBA, write to the special education coordinator:
"I am requesting that the IEP team conduct a Functional Behavior Assessment for [student's name] to assess the function of [describe the target behavior(s)], which is impeding [his/her/their] access to educational programming. I am requesting that this be addressed at the next IEP meeting and that the AED process be initiated if additional assessment consent is needed."
If the FBA is being requested as an additional evaluation area rather than as part of an existing evaluation, the school must convene an AED meeting within 30 days of your request and proceed through the evaluation consent process.
Common DC School FBA Failures
Observation of one setting only: The evaluator watches the student during math, concludes the behavior is escape-motivated from math tasks, and misses that the same behavior also occurs during free reading — where escape from academic demand is not the explanation.
No parent or student interview: IDEA and best practice require that parents be interviewed as part of the FBA. Their observations at home, in community settings, and in less structured environments often reveal functions that classroom observation alone misses.
No A-B-C data: The evaluator describes the behavior but does not systematically analyze antecedents and consequences across multiple observations. Without A-B-C data, the functional hypothesis is speculation.
Behavioral description that conflates topography with function: "Student aggresses toward peers" describes what the behavior looks like, not why it occurs. A proper FBA identifies whether that aggression is attention-seeking, escape-motivated, sensory, or something else entirely.
