ABC observation sheet
ABC is a simple structure for organizing observations: A — antecedent or setting, B — observed behavior, and C — consequence or what happened next. The labels organize a record; they do not establish why an event occurred.
ABC observation record
| Date & time | A — What was happening just before? | B — What did you directly observe? | C — What happened immediately next? |
|---|---|---|---|
| Example: Tue, 4:10 pm | Homework materials were placed on the table; the TV was on. | Child pushed the paper away and said, “No homework.” | Adult turned off the TV, paused for two minutes, then offered two task choices. |

Recording tips
Write what another person could observe
Use concrete details
Include the time, place, people present, exact words when relevant, and the visible sequence of events.
Separate facts from interpretation
“Covered ears for 20 seconds” is more specific than a broad label. Leave unknown details blank rather than filling them from memory.
Record positive moments too
The same structure can document calm transitions, requests for help, and activities that went as planned.
Keep one event per row
A single sequence is easier to read later than several events combined into one entry.
