Step 1.12 Plan a data collection strategy
You should develop your data collection strategy and decide on data collection forms to use prior to implementing least-to-most prompting.
At a minimum, data collected should include collecting information on the following:
unprompted correct responses
Correct response at the independent level of the hierarchy. This is the goal; thus, these responses should be reinforced and counted.
prompted correct responses
Any correct response that occurs after any of the prompt levels of the hierarchy. These responses should be reinforced and counted.
incorrect responses
These can be either unprompted errors - incorrect responses made at the independent level of the hierarchy (before any prompts are delivered), or prompted errors - incorrect responses made after any of the prompt levels of the hierarchy. For any incorrect response, you will be using a correction procedure.
no responses
Toddler does not make any response after the delivery of the last level in the hierarchy.
