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.

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.
