Behavior Frequency Data Sheet
A frequency data sheet answers one simple question: how often does this behavior happen? You make a tally mark every time the behavior occurs during an observation period, then add them up. If your observation times vary from day to day, you can turn the count into a rate (occurrences per hour) so you are always comparing fairly.
Who it’s for: parents, teachers, therapists • Best for: behaviors you can count in clear, separate occurrences (hitting, calling out, requesting) • Time: one tally mark per occurrence

How to use the frequency data sheet
- Define the behavior clearly at the top so anyone would count the same thing.
- Note the start and end time of your observation.
- Make one tally mark each time the behavior happens.
- At the end, total the marks (the count).
- To get a rate, divide the count by the minutes observed and multiply by 60 (for example, 6 in 30 minutes = 12 per hour).
Reading the pattern
Use page 2 to plot the rate each day and connect the dots. A line that trends downward over a week or two is real, visible progress — exactly the feedback that is so hard to feel day to day. Look at your best (lowest) day and ask what was different: more sleep, a calmer schedule, a support that was in place? That is often your clue to what helps.
Tips
- Frequency works best for behaviors with a clear start and stop. For behaviors that last a while, use the Duration Data Sheet instead.
- Keep the observation window consistent when you can — it makes the trend cleaner.
- A clicker or a note on your phone works too; just transfer the totals to the sheet.
This sheet helps you record and organize behavior. It is not a diagnostic tool; review findings with a qualified professional.
