Glenbrook Hsd 225, IL - District Data

Original Research by School Decision on Glenbrook Hsd 225

Glenbrook HSD 225 is a high school district serving suburbs northwest of Chicago, drawing students from Glenview, Northbrook, Des Plaines, Deerfield, and nearby communities. It operates two main high schools—Glenbrook North and Glenbrook South—plus an evening program and off-campus option, serving a student body of about five thousand.

The district's student composition is predominantly white, with substantial Asian and Hispanic representation and a smaller share of Black students. The enrollment is balanced across grades. Free-or-reduced-price lunch data and special education enrollment percentages were not available, so a parent would want to ask the district directly about economic diversity and support structures for students with disabilities or English learners.

State testing data at the high school level is not reported for this district, which is typical for grades nine through twelve; Illinois assesses proficiency in grades five and eight, not high school. A parent evaluating Glenbrook's academic pathway will need to look beyond state testing to other signals. Graduation rate data was not provided, and chronic absenteeism sits in the top quartile among Cook County districts, meaning it is relatively low, which reflects consistent student engagement. The district's per-pupil spending is in the upper range for the county, supporting resource-intensive programming.

The housing market in the district's service area reflects affluent suburbs. Home values are substantially above state and national benchmarks, with considerable variation across zip codes; areas like Winnetka and Golf command significantly higher prices while Des Plaines is more modest. Rental costs are proportionally high as well. The market shows adequate inventory with modest year-over-year shifts. Mortgage affordability relative to local household income poses a real constraint for many families; rent-to-income ratios also run tight.

Beginning in the 2025-26 school year, the district is implementing a restructuring of its honors and advanced course tiers that reshapes how student achievement is weighted and recognized. The traditional honors designation will be renamed Enriched Honors while maintaining its existing weighting; a new tier called Accelerated Honors is being phased in for core courses starting with ninth-graders entering in 2029, at a higher weighted scale. This change aligns with Illinois's Accelerated Placement Act and directly affects GPA calculation, class rank, and transcript profiles—matters that matter for college applications. If you are considering a move into this district, the honors structure is actively evolving, so it is worth reviewing the district's current and planned course offerings and understanding where your student would place under the new framework.

The district operates school-specific websites and curricula; program data was not available in detail, so asking the individual high schools directly about AP offerings, STEM pathways, arts, athletics, and post-secondary dual-credit or career technical options will give you a clearer picture of what is available. The evening and off-campus programs suggest flexibility for students whose circumstances require non-traditional scheduling.
