Reported figures, 2022–2023

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.

Free or reduced-price lunch

Share of students eligible for free or reduced-price meals — the most widely used proxy for concentrated poverty in a school. Districts under community eligibility report all students as eligible, which inflates the figure and makes cross-district comparison unreliable.

§02
