The data story: Northbrook Junior High School vs Field School

Northbrook Junior High School holds an overall rating of 9.9/10 against Field School's 9.2/10, a 0.7-point difference. More telling is where each school sits in the state: Northbrook Junior High School ranks #2 of 3,813 Illinois schools, putting it at the very top of a competitive field, while Field School ranks #66 of 3,813 — still an exceptional standing, but a full 64 positions back.

A smaller school body at Field School may translate to a tighter-knit social environment even as the ratio difference remains narrow.
