Ten tables presenting national data on private schools are provided. Data were collected using the Private School Questionnaire, which is one of seven questionnaires comprising the 1987-88 Schools and Staffing Survey developed by the United States Department of Education's National Center for Education Statistics. The survey, conducted by the Bureau of Census, began with a February mailing of the questionnaire to 3,513 administrators of private schools in the school sample, which was selected primarily from the Quality Education Data file on private schools. A follow-up questionnaire mailing and subsequent telephone follow-up were conducted for non-respondents. The tables provide data for 1987-88 on the orientation, tuition amount, programs and services offered, admission criteria, religious denomination, association membership, number of private schools, enrollment by grade level, and selected other characteristics. Tables also show private high school graduation rate, 1987 college application rate, and 12th graders in college preparatory courses in 1988, by selected characteristics. Standard errors for key private school statistics, for private religious schools by denomination, and for private schools by association membership are reported. Technical notes on the survey methodology and the questionnaire are provided. The schools and staffing survey instrument is appended. (TJH)
