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
