The teacher remains alert to the interests of each child and facilitates individual research in following interests. There are no curriculum requirements except those set by the state, or college entrance requirements, for specific grade levels. These take a minimum amount of time. From age six on, students design contracts with the teacher to guide their required work, to balance their general work, and to teach them to become responsible for their own time management and education. The work of the 6+ class includes subjects usually not introduced until high school or college.
