• The duration of the incentive program--- The success of your incentive program hinges on the length of time student must perform a behavior before they receive their reward. If it run too long, students will lose interest or feel the reward isn’t worth the wait. If the duration is too short, you will begin to feel like you spend more time rewarding your students than teaching. A good rule of thumb is to run the first couple of incentive programs for about two weeks. Then, once your students have gotten the hang of things and behaviors has begun to improve, increase the duration of the incentive to three or four weeks.
