Many Christian schools use the Carver model as the way in which to think about governance. This model came to prominence in 1990 when John Carver published Boards that Make a Difference. It made an immediate splash in Canada and then spread into the States. The book addresses governance in all not-for-profits, not specifically education, and has no Christian formulation. It nonetheless addressed a significant problem that Christian schools faced about the cooperation / conflict that inevitably came about when Heads of School (the professional leader of the school) interacted with the Board (the volunteer employer of the Head). This dynamic continues to this day.
