Repeat points on several different occasions that are at least several days apart. Use open and closed-ended questions to be sure trainees retain the information.

You might learn better ways to do the job yourself. Answer Questions Thoroughly. Questions help you locate points of confusion or gaps in a trainee's knowledge.
