ABC data is a record of what happened before a behavior (antecedent), the behavior itself, and what happened right after (consequence).
Example
Antecedent: the teacher asks the learner to start a worksheet. Behavior: the learner pushes the worksheet off the desk. Consequence: the worksheet is removed and the learner leaves the table.
Key points
- Record facts you can see and hear, not guesses about feelings.
- ABC data help the supervisor work out why a behavior is happening.
- Patterns across many entries matter more than a single event.
Exam tip
A question about “what happened just before” points to the antecedent. “What followed” points to the consequence.
Common mistake
Recording opinions or guesses in the antecedent or consequence columns instead of what was observed.
Quick check
What does the “C” in ABC stand for? Consequence, meaning what happened right after the behavior.
