What Shows That a Lesson Travels Into the Work?

A teammate can repeat the steps from a training session and still feel unsure when the situation changes. So what should a lesson help them do: recall the instructions, choose the right next step, or explain when the process no longer fits?

I’m curious about the moment after the explanation—when someone has to use the idea in a real task. What kind of practice or follow-up helps you notice whether the learning is usable, without making every check feel like an exam?
