Exact-moment scoring
Record present only when the behavior is occurring at the scheduled moment. Activity before or after that moment does not count.
Momentary Time Sampling for ABA behavior observation
Momentary time sampling estimates behavior occurrence from scores recorded at predetermined moments. Set a schedule, score whether the target behavior is occurring at each prompt, and review the sampled percentage.

Missed prompts
Missed moments remain separate from not-present scores. The estimate divides present scores by valid scores and shows coverage of the planned schedule.
Repeat observations
Keep the schedule and context with each result. Compare later estimates descriptively when those conditions are similar.
What does the recorder score?
Whether the target behavior is occurring at the exact predetermined moment.
Does a missed prompt mean not present?
No. Missed prompts are tracked separately and do not enter the occurrence denominator.
Does this count behavior between prompts?
No. The result is a sampled estimate, not an exact count or duration.
What is saved from this page?
The reusable tool configuration is saved. In-memory scores and missed prompts stay out of client records.
