Tabulated data are presented on private schools and private school teachers and administrators. School characteristics are included, along with data on program emphasis, admissions criteria, and graduation and college application rates. Data reported for teachers includes: (1) personal characteristics; (2) educational level; (3) experience; (4) salary and incentives; (5) non-school employment; and (6) teachers' attitudes about and experience with teaching. Similar data are reported for school administrators. Each table contains national estimates for all schools and for public and private schools. Private schools are described according to a nine-category typology recently developed by the National Center for Education Statistics (NCES). Data were collected through the 1987-88 Schools and Staffing Survey (SASS) developed by the NCES and conducted by the Department of the Census. Highlights of the survey include the following data: (1) the reported average salary for private school administrators was $20,206, compared to $41,924 for public school administrators; (2) about one-half of all private school administrators reported having some difficulty in filling teacher vacancies; (3) despite the salary differentials, close to one-third of the private school teachers reported that they would become a teacher again; and (4) teachers in private schools report a stronger sense of a shared school mission. The SASS consists of seven questionnaires, which are described along with other technical considerations in a methods section that follows the tables. The private school sample consisted of 3,513 schools, for which the survey responses of 3,513 principals and 11,529 teachers were analyzed. Sixty-five tables of data are provided. (SLD)
