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 Marysville Charter Academy for the Arts, the student:teacher ratio has fallen 11% over the 5-year window — from 18.6:1 in 2020 to 16.6:1 in 2024. The gap vs US average of 15.4:1 has narrowed — from 3.2:1 above in 2020 to 1.2:1 above in 2024.
