This report describes trends in Catholic high schools over the past 10 years. Data were derived from a survey of 500 Catholic secondary schools. A total of 293 questionnaires were returned, a 59 percent response rate. In addition to monitoring changes in income and expenses, tuition, and salaries, the report provides an analysis of information about emerging administrative structures. Salaries and stipends have increased, bringing religious teachers' stipends and lay teachers' salaries closer together. The gap between salaries in public and Catholic high schools has remained constant since 1992. Data show that schools are working hard to balance necessary increases in tuition with expanded financial programs, placing increasing emphasis on development efforts. Within a relatively short time, many schools have generated fairly successful, multifaceted programs. The data also show new evidence of the success of increasingly sophisticated student-recruitment and marketing programs. Much remains to be done in the areas of faculty compensation, financial aid, maintenance, and student recruitment and retention. Despite financial strains, schools show evidence of effectiveness, efficiency, and committed staff and parents. Thirty-five exhibits are included. Appendices contain information on average high school models; summary tables by governance, region, and enrollment; a list of schools in the report; and a copy of the survey instrument. (LMI)
