From the 1850s to the 1970s the teaching force in Catholic schools in Australia was dominated by priests, female religious and brothers. This paper details the scope of existing research on these teachers, the demands of their religious vocation, their own education, the atmosphere which they established in the schools, leadership opportunities, and the "darker side" of their way of life. Such expositions can promote reflection on the possibility that teaching can be influenced by discourses of "vocation" and "the giving of service", every bit as much as it can be by "industrial" and "labour" perspectives.
