Free opportunity (trial-by-trial) data sheet

Use this sheet for goals written as a number of opportunities, such as “in 4 of 5 opportunities.” Each box is one opportunity, marked independent (+), prompted (P), or not demonstrated (−).

Preview shows 6 of 15 rows.

Record up to 10 opportunities per session, matching the goal's denominator.
Define in advance what counts as an opportunity so every data collector records the same thing.
Count only + marks toward the criterion unless the goal specifies prompted responses.

When to use this sheet

Requesting help, self-advocacy, greetings, or using a strategy when a defined situation occurs
Following directions, where each direction given is one opportunity
Planned trials during instruction

How to use it

Define what counts as an opportunity before collecting data, and write the definition on the sheet.
Mark NA when no opportunity occurred, so missing data isn't counted as failure.
Count + marks toward the criterion unless the goal counts prompted responses.

Questions

What if fewer opportunities occur than the goal requires?

Record what happened and note it. Many teams plan contrived opportunities so the required number occurs. A session with too few opportunities usually shouldn't count toward mastery.

Should prompted responses count?

Only if the goal says so. Recording prompts separately shows whether independence is growing, which is often the real target.
