Summary:
Northbrook Education Service District 27 has three schools serving preschool through grade 8: Hickory Point Elementary School (PK–2), Shabonee School (grades 3–5) and Wood Oaks Junior High School (grades 6–8). Each enrolls about 425–460 students. The two schools with reported test results are well above state averages in both subjects, with the clearest shared strength in mathematics: their average result is 85%, compared with 40% statewide, a 45-point lead.
There is no single leader across both subjects: Wood Oaks leads in all-grade ELA, at 91% versus 90% at Shabonee, while Shabonee leads in math, at 86% versus 84% at Wood Oaks; each school-to-school gap is about 2 points. Both schools are far above state results in ELA and math, with school-to-state gaps of 33–35 points in ELA and 44–46 points in math. Science results are also strong: Shabonee has 80% in grade 5, against 48% statewide, and Wood Oaks has 93% in grade 8, against 52% statewide; because these are different grades, they do not show which school performs better in science. Hickory Point has no test results in the supplied data.
Results rose at both tested schools from 2024–2025 to 2025–2026, but the relative trend differed by subject: the two-school average increased about 2 points in ELA, while the state rose 3 points, narrowing the average ELA lead by about 2 points; in math, the average rose about 3 points as the state gained 1, widening the lead by about 2 points. SchoolDigger gives both schools five stars and places them at the 98th statewide percentile. Student-teacher ratios in 2024–2025 were 11.6 at Hickory Point, 12.0 at Shabonee and 9.8 at Wood Oaks, so the lower ratio at Wood Oaks does not align with a lead in both subjects. All three schools reported similar shares eligible for free/reduced lunch in 2021–2022: 0.7% at Hickory Point and Shabonee and 0.6% at Wood Oaks; these historical figures are context, not an explanation of test results.
