The current literature on year-round education is replete with feasibility studies; reports on operational programs; and thoughtful consideration of the potential effects of year-round education on the community, school, family, and child. Lay boards of education are frequently asked to make decisions on whether to implement year-round programs on these rather superficial data. More hard data of the type being gathered in Prince William County, Virginia, are needed if boards, school divisions, and communities are to make intelligent choices. An effort is being made to stimulate the development of a body of knowledge on year-round education to meet the information needs of the public, school boards, businesses, public agencies, and school personnel.
