The Educational Research Services, Inc.'s National Survey of Salaries and Wages in Public Schools for 1985-86 collected data on the number of personnel in 23 professional and 10 support positions in public school systems throughout the United States, as well as data on the fall 1985 enrollment of these systems. Various pupil-staff and teacher-staff ratios computed using these figures are reported in this set of 44 tables. The data analysis and reporting procedure used allowed for comparisons of staffing ratios within both enrollment categories and expenditure categories. Two of the tables in this report are summary tables showing mean numbers of pupils and teachers per professional and per administrative staff member in the 1,104 reporting systems; 21 tables show percentile distributions, means, and ranges of pupil-staff and teacher-staff ratios by enrollment group; and 21 tables show percentile distributions, means, and ranges of staffing ratios by per-pupil expenditure level and enrollment group. The report is introduced with a review of the data and staffing positions covered, a description of the sampling procedure, an analysis of each table's contents, comments on use of the data, and highlights of the findings.
