Why this matters
NCES pupil:teacher ratio is enrollment ÷ full-time-equivalent teaching staff. It isn't class size — specialists, resource teachers and coaches pull the ratio down without changing what's happening in a classroom — but a lower ratio generally means more adult attention per student.
What we're seeing
At Andersen, the student:teacher ratio has risen 11% over the 5-year window — from 15.4:1 in 2021 to 17.1:1 in 2023. Despite that, the gap vs US average of 15.4:1 has actually widened — from 0.0:1 above in 2021 to 1.7:1 above in 2023.
