Functional Behavior Assessment Data Sheet by "School Psychology Shop for XBA IEP and Behavior" allows you to identify patterns in behavior. At a glance, track and analyze antecedents, record behavior, time when behavior happened, activity child was involved in when behavior happened, the setting where the behavior took place, consequence for the specific behavior and the observed function of the behavior. You are also able to record the start and end time of your observation so you can identify how many events or how many times the behavior happened within a given time interval.
Simply use tallies in the boxes provided to record your observation and watch the pattern emerge! Gotta love data :)
