This report is compiled from information provided by National Association of Independent Schools (NAIS) member schools in a 1986 survey of student and staff counts and financial operations. The first section summarizes survey results from 1982-83 to 1986-87 on enrollment and number of member schools, financial aid, and financial operations data in average dollars per student. Of the country's approximately 110,000 elementary and secondary schools, it is estimated that about 1,700 are independent schools; half are NAIS members surveyed in this report.
