Free-and-reduced-price lunch data was not available, which often signals a higher-income population overall.

The Northbrook School District is currently undertaking its most significant facilities initiative in decades. In April 2025, voters approved a substantial bond referendum to fund construction of a new Meadowbrook School, additions and renovations to Greenbriar and Northbrook Junior High, and infrastructure upgrades to Westmoor. Construction is expected to begin in summer 2026 and will shape the physical learning environment over the next several years. The district has also implemented updated math curricula across K-8 in recent years, using Bridges in Mathematics for elementary grades and Big Ideas: Modeling Real Life for junior high, affecting how students at Northbrook Junior High are instructed.
The community itself is an established, affluent suburb with a strong tax base. The housing market reflects substantial home values and rents, with median home prices well above state and national benchmarks. Downtown Northbrook, centered around the Metra station and civic anchors like the library and village green, is walkable and lively, though the broader village is car-dependent. Major employers including Allstate, Underwriters Laboratories, and pharmaceutical firms anchor local economic life. Significant redevelopment is underway at the Northbrook Court site, a major mixed-use project that could reshape residential and commercial activity, with housing construction expected to start in summer 2026.
Northbrook Junior High serves a community of high academic expectations and stable, affluent family circumstances. The school's test results reflect that context while also demonstrating solid instructional practice across its grade span, with particular strength in reading and science. The district's recent bond commitment and curriculum modernization signal continued investment in teaching and facilities, though families should anticipate construction activity at the school during the renovation phase.
