| 1 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. |
| 2 The private school teacher number is an actual number from the 2009–10 PSS. |
| NOTE: The pupil/teacher ratios were derived from tables 1 and 16. Teachers 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. |
