    A free ABC behavior chart

    Antecedent, behavior, consequence. A clear, proven structure for understanding what sets a behavior off and what keeps it going.

    Free to start · about 30 seconds to log · your data stays private

    What you’ll notice

    • Antecedent: what happened right before
    • Behavior: what was observed, described without judgment
    • Consequence: what happened right after
    • Patterns in triggers and what reinforces them

    Why it helps

    Behavior makes more sense once you can see what surrounds it. The ABC structure captures the before and after, which is where the explanation usually lives. Over a series of entries the triggers and reinforcers become visible, so support can target the real driver instead of the surface behavior. It also gives a behavior analyst or teacher a clean, consistent record to work from.

    How it works

    1. 1

      Log an event in three parts: what came before, what happened, what came after.

    2. 2

      Describe the behavior plainly, without judgment.

    3. 3

      Your report surfaces the recurring antecedents and consequences behind the pattern.

    The thinking behind it

    Based on the ABC framework (antecedent, behavior, consequence) widely used in applied behavior analysis and classrooms. It is a structured observation log, not a behavior plan, and it keeps the language descriptive rather than evaluative.

    Specthrive’s trackers are developed with a licensed clinical counselor (LPCC) on our founding team.
