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 El Monte Union High School Community Day, the student:teacher ratio has risen 1% over the 5-year window — from 8.2:1 in 2020 to 8.3:1 in 2024. The gap vs US average of 15.4:1 is roughly flat (~7.1:1 below).
