Free frequency & rate data sheet

Use this sheet to count each time a clearly defined behavior occurs during a set observation period. When observation lengths vary, it calculates rate per minute so sessions stay comparable. A timed-probe version (for example, digits correct per minute) is generated automatically for rate goals in the builder.

When to use this sheet

  • Discrete, countable behaviors with a clear start and end (hand raises, initiations, coping-strategy use)
  • Timed fluency probes reported as correct per minute
  • Goals to increase or decrease how often something happens

How to use it

  1. Write an operational definition of the behavior so different observers count the same thing.
  2. Keep the observation period the same length. If it varies, compare rate, not raw counts.
  3. Use tally marks during observation and total them afterward.

Questions

When is frequency the wrong measure?

Frequency is a poor fit for behaviors that last a long or variable time, such as staying engaged. Use duration for those. It's also a poor fit when opportunities vary a lot from day to day. Use opportunities instead.
