The Behavioral Observation of Students in Schools (BOSS) is an observation-based system for coding classroom behavior. BOSS is also useful for measuring ADHD symptoms as it has been shown to differentiate between children with ADHD and typically developing children. BOSS allows systematic recording of children's behaviors in the following domains: active engaged time, passive engagement time, off-task motor activity, off-task verbal behavior, off-task passive behaviors, and teacher-directed instruction.
