During the 1983-84 school year, 58 percent of the 27,700 private schools in the United States reported benefiting from publicly funded services. The source of these data is the National Survey of Private Schools, fall 1983, carried out by Westat, Inc., under contract with the Center for Education Statistics (CES). The survey supplemented the CES list of private schools with additional schools discovered through intensive investigation of 75 geographical areas. Questionnaires were sent to a sample of 2,298 of the schools thus identified, and responses were received from 1,869 (81 percent) of these schools. Catholic schools benefited most: students at 93 percent of the 9,700 Catholic schools received publicly funded services; while students at 36 percent of the 10,000 "other affiliated" schools and 42 percent of the 8,000 "not affiliated" schools received such services. Types of service include the following: (1) transportation; (2) library; (3) school lunch, milk; (4) health services; (5) remedial education; (6) bilingual education; (7) handicapped; (8) vocational education; (9) guidance; (10) speech therapy; and (11) other services. The largest sources of federal money spent in private schools are programs funded by Chapter 1 and Chapter 2 of the Education Consolidation and Improvement Act (ECIA), 1981. The appendix contains a brief description of these programs, as well as of standard errors for percentages presented in the bulletin. (MLF)
