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 Bryant Montessori, the student:teacher ratio has risen 13% over the 5-year window — from 9.9:1 in 2020 to 11.2:1 in 2021. The gap vs US average of 15.4:1 has narrowed — from 5.5:1 below in 2020 to 4.2:1 below in 2021.
