Northbrook Junior High School vs Field School

Northbrook Junior High School and Field School sit 2.2 miles apart in Northbrook, Illinois, and both earn elite scores — but the gap between them is meaningful at scale. 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.

On academics, the two schools are close but not identical. Northbrook Junior High School earns a 9.9/10 academic score versus Field School's 9.6/10. The growth score tells a sharper story: Northbrook Junior High School posts a 9.8/10 on student growth compared to Field School's 8.4/10. That 1.4-point difference on growth suggests Northbrook Junior High School is accelerating students more effectively relative to their starting points — not just enrolling students who already test well.

Both schools serve grades 6–8, so the academic trajectory is the same. Enrollment diverges significantly: Northbrook Junior High School runs at 649 students while Field School enrolls 316, making Field roughly half the size. Student-teacher ratios are comparable — 9.0:1 at Northbrook Junior High School versus 9.6:1 at Field School — meaning both offer strong individual attention, though Northbrook Junior High School edges ahead on that metric as well. A smaller school body at Field School may translate to a tighter-knit social environment even as the ratio difference remains narrow.

Both campuses are genuine outliers in Illinois — ranking in the top 2% of more than 3,800 schools is not a distinction most families have access to. The practical decision comes down to how much weight a family places on that growth score differential and whether school size shapes their preference.
