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.

5 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.

Respondents were instructed to respond only for those times that were during normal school hours or when school activities or events were in session, unless the survey specified otherwise.
