Conducting a Functional Behavior Assessment (FBA) is a systematic, data-driven process led by a Board Certified Behavior Analyst (BCBA) to identify the root causes of challenging behaviors. The process follows these primary steps:

1. Data Collection through Observation and Interviews:

The BCBA gathers information using indirect methods, such as interviews with parents, caregivers, and teachers. This is paired with direct observation in natural settings (home or school) using ABC recording to document the Antecedents, Behaviors, and Consequences.

1. Identifying the Four Functions of Behavior:

The collected data is analyzed to determine which of the four primary functions the behavior serves:

• Escape/Avoidance: Seeking to get out of a task or situation.
• Attention: Seeking positive or negative interaction with others.
• Access to Tangibles: Seeking a specific item or activity.
• Sensory Stimulation: Seeking internal feedback or self-soothing.

1. Conducting a Functional Analysis (FA):

If initial data is inconclusive, the BCBA may perform a functional analysis. This involves systematically manipulating environmental variables in a controlled setting to confirm the exact trigger and reinforcement for the behavior.

1. Developing a Behavior Intervention Plan (BIP):

The BCBA synthesizes the findings to create a personalized BIP. This plan identifies replacement behaviors (positive skills that serve the same function) and includes prevention strategies, reinforcement systems, and data collection methods to track progress.
