4 Primary schools are defined as schools in which the lowest grade is not higher than grade 3 and the highest grade is not higher than grade 8. Middle schools are defined as schools in which the lowest grade is not lower than grade 4 and the highest grade is not higher than grade 9. High schools are defined as schools in which the lowest grade is not lower than grade 9. Combined schools include all other combinations of grades, including K–12 schools.
5 These estimates exclude data from the 73 schools that did not report estimates of student race/ethnicity.
6 Student/teacher ratio was calculated by dividing the total number of students enrolled in the school by the total number of full-time-equivalent (FTE) teachers and aides. The total number of FTE teachers and aides is a combination of the full-time and part-time teachers and aides, including special education teachers and aides, with an adjustment for part-time status.
