The most important contribution that parents make to the school is working with the teachers in the classroom. Each class is always staffed by the teacher, an assistant teacher and two parents. Parents are scheduled in the classroom on a rotating basis, averaging twice a month. If necessary, a parent may hire a substitute from a list provided by the school. Parent participation, however, is significant to the child, and the school recommends that substitutes be used only in emergencies. All families are expected to participate in fundraising events that provide money for scholarships and capital improvements, and to work on committees that meet a variety of other needs. This parental involvement not only keeps the tuition at a reasonable level, but also brings home and school closer together, creating a closely-knit community that fosters friendships among parents as well as children. The parents, with their diverse professional skills and creative talents, contribute to the quality of their children's educational experience and, in turn, gain reassuring insights into the behavior, skill development, and social interactions of young children.
