To assist administrators of Roman Catholic elementary and secondary schools, this manual examines 15 primary areas of responsibility or tasks for Catholic principals. Using a checklist format, the manual discusses a number of aspects of each task, including a definition of that task, a description of the principal's responsibilities, lists of the principal's administrative actions and of the school board's actions and policies, information to put in the faculty and parent/student handbooks, references for helpful resources, and questions on issues the principal should address. Included in the principal's areas of responsibilities are school, religious, staff, curriculum, student, and financial leadership as well as considerations about school philosophy, the board of education, parents, church authorities, religious orders, the law, government aid to private schools, public relations, and evaluation of students, faculty, and administrators.
