Moving Beyond the One-Person FBA: A Team-Based Approach to High-Quality FBAs
Written by Heather Volchko, BCBA
In many districts, the pressure to complete FBAs collides with a simple reality: staff are already overloaded. So, how do we do this well without further burning people out? The honest answer is this: not by expecting one person to do it. High-quality FBAs emerge from better design, not more individual effort. When districts treat FBAs as a shared, role-aligned process rather than an isolated task assigned to a single staff member, both quality and feasibility improve.
Too often, FBAs are positioned as the responsibility of a psychologist or behavior specialist working in relative isolation. That model is not only inefficient but also fundamentally misaligned with the complexity of student behavior. Behavior is contextual and relational, influenced by instruction, environment, sensory needs, and lived experiences. No single discipline holds all of that insight.
If we want FBAs that are both rigorous and realistic within existing workload constraints, we need to shift from “Who does the FBA?” to “How do we distribute the evaluation meaningfully?”
“Behavior is contextual and relational, influenced by instruction, environment, sensory needs, and lived experiences. No single discipline holds all of that insight.”
Reframing the FBA as a Team-Based Process
A high-quality FBA is not an event - it is a coordinated process that unfolds across roles. When structured well, each contributor operates within their existing scope of practice rather than taking on additional, unsustainable tasks.
At its core, the FBA becomes a system of aligned contributions:
Teachers identify and define the problem with specificity
Special education administrators coordinate decision-making and ensure procedural integrity
Psychologists guide the assessment design and ensure methodological rigor
Paraprofessionals and classroom staff collect observational data
Case managers ensure that evaluation timelines are adhered to and that the evaluation is completed with fidelity
Related service providers add contextual information to aid in behavioral interpretation
The team collectively synthesizes findings to determine function
Case managers enter the evaluation into the district’s documentation system and review findings at the meeting
This is all about structuring a shared ownership of an evaluation designed to be completed by a multidisciplinary team.
A Walkthrough of a Distributed FBA Process
Consider what this looks like in practice:
The process begins where behavior is most visible - within the classroom. Teachers are not expected to conduct full FBAs, but they play a critical role in flagging concerns early and clearly. Instead of broad statements like “noncompliant” or “disruptive,” teachers define observable patterns: when the behavior occurs, what it looks like, and initial hypotheses about triggers.
From there, special education administration facilitates a structured “needs assessment.” This step is often overlooked but essential to preventing unnecessary or poorly scoped FBAs. The team determines whether an FBA is warranted, clarifies the target behavior, and secures consent. This ensures that the assessment is both purposeful and compliant from the outset.
Once initiated, the psychologist or behavior specialist does not collect all the data themselves. Instead, they design the data collection plan. This includes selecting appropriate methodologies (e.g., ABC recording, partial interval, direct behavior ratings), defining operationalized behavior terminology, and ensuring interobserver clarity. Their role is precision.
Data collection is then distributed. Paraprofessionals and classroom staff who are already embedded in the student’s daily environment collect structured observations. This is a critical efficiency lever: the people closest to the behavior are best positioned to capture it in real time. With clear tools and training, this does not add a significant burden - it organizes what they are already seeing.
Throughout this process, the case manager plays a critical behind-the-scenes coordination role. They ensure evaluation timelines are adhered to, monitor progress across team members, and ensure fidelity to procedural and compliance requirements. This prevents delays and keeps the assessment moving forward without over-relying on any single contributor.
At the same time, related service providers deepen the analysis. Social workers may identify distress-related response patterns or relational dynamics. Occupational therapists may identify sensory sensitivities or regulation challenges. These perspectives do not replace behavioral data - they contextualize it.
Once sufficient data is gathered, the psychologist synthesizes the information. Patterns are analyzed across settings, antecedents, and consequences. Hypotheses about function are developed - not in isolation, but in preparation for team validation.
Finally, the team reconvenes to collaboratively determine function. This step matters. Function is not just a technical conclusion; it is a shared understanding that drives intervention. When multiple disciplines contribute to that determination, the resulting plan is more likely to be both accurate and implementable.
To close the loop, the case manager transitions the team’s work into formal documentation. Often, this means migrating a collaboratively developed ancillary document into the district’s official system, ensuring that the final evaluation reflects the full scope of team input while meeting documentation standards. The case manager is also typically the one who presents the evaluation results and findings to the case conference committee.
Why This Model Reduces - Not Increases - Burden
At first glance, involving more people might seem to add complexity. But, in practice, it does the opposite.
When FBAs are centralized, bottlenecks form. A single psychologist or specialist becomes responsible for design, data collection, analysis, and reporting. This leads to delays, rushed conclusions, or incomplete assessments.
By contrast, a distributed model:
Reduces duplication of effort (no one person is trying to do everything)
Increases data quality (observations occur across times, settings, and staff)
Builds shared ownership (interventions are more likely to be implemented with fidelity)
Aligns with existing roles (staff contribute within their expertise rather than outside of it)
This is a systems solution to a systems problem.
“A distributed evaluation model is a systems solution to a systems problem.”
Making It Work: Key Conditions for Success
Of course, collaboration alone does not guarantee quality. The process must be intentionally designed and supported.
Clarity is the first requirement. Each role must be explicitly defined. Ambiguity leads to gaps or redundancy, both of which undermine efficiency.
Second, tools must be practical. Data collection forms, operational terminology, and guidance documents should be streamlined and attainable. If tools are overly complex, they will not be used consistently.
Third, training must be targeted. Not everyone needs to know everything about FBAs. Teachers need to recognize and describe behavior patterns. Paraprofessionals need to collect data reliably. Psychologists need to ensure methodological integrity. Precision in training reduces unnecessary cognitive load.
Finally, leadership must protect the process. This includes scheduling time for team discussions, prioritizing FBAs appropriately, and reinforcing that this is shared work - not an individual burden to absorb.
The Bigger Shift
At its heart, this approach reflects a broader shift in how we think about expertise in schools.
No single discipline - whether psychology, behavior analysis, social work, or education - has a complete view of why a student behaves the way they do. Each field offers a lens. The strength of an FBA lies in how those lenses are combined.
When districts embrace this, FBAs become more than compliance tasks. They become opportunities for interdisciplinary problem-solving that lead to more effective, humane, and sustainable interventions.
And importantly, they become doable - especially in systems where time and capacity are limited.
