ABC Data
Log and view Antecedent-Behavior-Consequence data to support functional assessment hypotheses.
ABC Data Collection
Track Antecedent-Behavior-Consequence patterns to support functional behavior assessment. ABC data helps identify patterns and hypotheses; it does not confirm behavioral function by itself.

Calendar Navigation
Calendar shows dates with recorded ABC data marked with dots.
Select any date to view entries from that day.
Navigate months using arrows or the date picker.
ABC Entries
Tap Log ABC to record a new observation.
Each entry captures:
- When - Date and time
- Setting - Where it occurred
- Antecedent - What happened immediately before
- Behavior - The specific behavior observed
- Consequence - What happened immediately after
Entries display grouped by date. Select any entry to view full details or edit.
Best Practice
Record ABC data during or immediately after the behavior occurs so the descriptive record is as accurate as possible. Use patterns from ABC data with the rest of the assessment process before drawing conclusions about function.
