Scoring Rule
An interval is scored as occurrence if the behavior happens at any point within that interval.
Partial-Interval Recording
Partial-Interval Recording is an ABA interval measurement tool for practitioners and assigned recorders when continuous exact counting is impractical. It helps score whether the target behavior occurred at least once within each interval and calculates the percentage of intervals with occurrence.

Result Meaning
The result is an interval occurrence estimate, not an exact event count or exact duration.
Rule Separation
Partial-interval scoring remains separate from whole-interval and momentary time sampling rules.
What counts as occurrence in partial-interval recording?
Occurrence means the behavior happened at least once at any point during the interval.
Does this tool count every behavior event?
No. It calculates the percentage of intervals with occurrence and does not produce exact counts.
What happens if an interval is unscored?
The session is marked incomplete or handled with transparent denominator rules, depending on validated product behavior.
What is saved from the demo?
The tool and selected interval structure are saved; fictional interval scores are not saved as real client data.
