Functional assessment of hand flapping in a general education classroom.

A kindergarten boy flapped his hands during class. The teacher asked a behavior consultant to find out why.

The consultant watched for one morning. He changed three things: how hard the task was, how much help the teacher gave, and whether other kids were watching. Hand flapping only jumped when the teacher gave a tough task and walked away.

Hand flapping was escape-maintained. The boy did it when work looked hard and no help was near.

The fix was simple. The teacher broke the task into smaller steps and stayed close to prompt. Flapping dropped to zero and stayed there.

Farrant et al. (1998) ran a similar classroom check with older kids who had ADHD. They also saw problem behavior plunge after the assessment. The 2001 case shows the same logic works for younger, typical kids.

Kodak et al. (2013) later trimmed the process even more. Teachers used quick trial-by-trial tests and still found the right function. Their method is faster, but both studies prove staff can do the analysis without pulling the child out of class.

Kestner et al. (2019) sound a caution note. They say look at class-wide basics first—like how clear lessons are—before starting an individual FBA. The 2001 study did not check these wider variables, so its fix might not work if the whole room is chaotic.

You can finish a useful functional assessment in one morning. Watch what happens when you change task difficulty, attention, and peer reactions. If behavior spikes only when work is hard and help is gone, try breaking the task and staying close. This quick loop keeps kids in class and saves you from long outpatient referrals.
