|Figure 11. Actual and projected numbers for the pupil/teacher ratios in elementary and secondary schools, by control of school: Fall 1994 through fall 2019|
NOTE: Since the biennial Private School Universe Survey (PSS) is collected in the fall of odd
numbered years, private school numbers for alternate years are estimated based on data from
the PSS. The pupil/teacher ratios were derived from tables 1 and 16. Teachers are reported in
full-time equivalents. Some data have been revised from previously published figures. Mean
absolute percentage errors of selected education statistics can be found in table A-2, appendix A.
