If the training seminar is for more than one day this will prepare you for the next day's sessions, clarifying the questions you still want answered. If possible, the attendees should review within 24 hours with someone who also attended the training. This works well if the day following the training session is a workday. It is imperative that management provide the review time that is part of the cost of the training. Further review sessions after one week, and one month will help maintain a freshness of the training.
Review increases the understanding and the retention of the subject matter covered in the training.
Thereby reducing the need for remedial training. Remembering what was learned increases the likelihood that the information will be used at the correct time, thereby pleasing a customer, probably reducing the need for a call-back, and consequently increasing profits. Otherwise the long-term benefits of the training may not materialize. This provides another opportunity for the attendees to review. And we know that we learn the most when we teach others.
