As others have said above, have them shop the comp. and score their experience. Ask them to tell you/show you how they would do things differently on anything they give a low score. On high score, ask them what they liked and how it made them feel. Also, have them shadow a strong agent or yourself. I also used to do in-house competitions. I would literally get out PosterBoard, and I would draw things like a tree. Then I would cut out little leaves and oranges etc.  One person would be leaves, one person would be oranges, and one person would be whatever else you want to put on the tree lol each time they got a good score- they got to put theirs on the tree with their score on it. Whoever had the highest at the end of the time (6 months) would win a day off with pay. You can choose the prize, but people enjoy extra time off more so than a gift card.
