What These Numbers Mean

Teacher FTE

Full-Time Equivalent counts part-time teachers proportionally. One full-time teacher = 1.0 FTE; two half-time teachers also = 1.0 FTE. This is the standard federal reporting unit.

Pupil : Teacher ratio

NCES-reported ratio divides total enrollment by teacher FTE. It is NOT the same as average class size — schools with specialists, coaches, and resource teachers will show lower ratios than typical class sizes.

How to read the trend

A falling pupil:teacher ratio (line going down) means more staffing per student — generally a positive signal. A rising line can indicate budget pressure or fast enrollment growth outpacing hiring. Always compare to the US average (dashed grey).

Student Support Staff (CRDC 2021-22)

Non-teaching staff the school reported to the federal Civil Rights Data Collection. Ratios use the current enrollment of 3,006 students, so they show roughly how many pupils each post covers.
