Data is needed in order to figure out why a certain behavior is occurring. ABC data is the typical assessment tool and involves directly observing and recording situational factors surrounding a problem behavior.

In ABC data collection, the type of data is broken out into three components: A-B-C

  • Antecedent = what happened before
  • Behavior = what the child did that is problematic
  • Consequence = what happened after

In this video, Robert discusses ABA data collection and how identifying the antecedents and consequences for a behavior will help clue you into why the behavior is occurring.
