Chore charts are also called reward charts, behavior charts, chore calendars, chore lists or task lists. A chore chart is a listing used to track and organize the house work. The chart can be physical or virtual and is often a means used by parents to post chores expected of their children. Different homes have different ways of organizing and implementing a chore system, including simple paper charts tacked on the refrigerator. There has been a lot of research, experiential evidence and discussion of chore charts.
