Demographic, organizational, and financial trends in Catholic high schools in the United States are described in this 1992 report. Data were obtained from a survey sent to a random stratified sample of 500 Catholic high schools in the United States, which yielded 278 usable returns. Information is presented on school administration, teachers, students, admission standards, facilities, parental involvement, finances, development programs, and governance and external relations. Findings indicate that the percentage of president-led Catholic high schools has risen to 20 percent. Teacher salaries and stipends have increased, and the gap between salaries in public and Catholic schools has narrowed slightly. Schools are working to balance necessary tuition increases with expanded financial aid programs, and are placing more emphasis on development efforts. Finally, the findings demonstrate strong support for the effectiveness and efficiency of Catholic schools. However, they face increasing financial strain that is balanced by committed principals, teachers, and parents. Thirty-five exhibits are included. Appendices contain average high school models; summary tables by governance, region, and enrollment; a list of represented schools; and the survey instrument. (LMI)
