Reported figures, 2022–2023

The Common Core of Data is a directory collection: it records size and staffing, not achievement. Nothing here says whether a school is good.

How these figures are defined

Enrollment

Students reported in the autumn headcount. Size is not quality — it is here because it is the figure every other one has to be read against, and because a school of 90 and a school of 4,000 are not comparable on anything else.

Teachers

Classroom teachers in full-time equivalents, so a half-time teacher counts as 0.5. Non-teaching staff are excluded.

Students per teacher

Enrollment divided by teacher FTE. It is not class size: it counts every teacher against every student, including specialists who never take a full class. A school can have 15 students per teacher and 30 in the room.

§02

Within Red Clay Consolidated School District

Schools in the same district, which is the comparison the data actually supports — a peer group defined by who runs them rather than by whichever names sort nearby.
