This report summarizes information provided by National Association of Independent Schools (NAIS) member schools surveyed in the fall of 1989. Information, which is supplied in narrative form accompanied by 29 statistical tables, includes enrollment, staffing, people of color, and financial aid data for the 1989-90 school year and financial operations data for 1988-89. The human and fiscal characteristics of NAIS schools for the most recently available school years are described. Data are reported in an aggregate manner according to common classifications of school type, school size, and geographic region. Among the key findings are the following: (1) enrollment in active member schools increased by 1.7 percent since 1988-90 and is up 14.5 percent since 1980-81; (2) for the first time, the number of women administrators exceeds the number of men; (3) students of color represent 12.7 percent of total enrollment in member schools; (4) percentage increases in total financial aid awarded and in the size of the average grant substantially exceed the percentage increase in the number of students receiving financial aid; and (5) during the 1980s, expenses for administrator salaries and for total benefits and payroll taxes show the greatest proportional increases among all categories of expense per student.
