About Glenbrook High School District 225

Glenbrook High School District 225 divides ordinary enrollment between Glenbrook North and Glenbrook South through a legal rule that reaches beyond the mailing address. Residents inside Northbrook’s corporate boundary attend North. Most residents inside Glenview’s corporate boundary attend South.

Willow Road and municipal history create the exceptions. Glenview territory north of Willow Road that was annexed on or after August 5, 2008 belongs to North, as do unincorporated homes north of the road. Unincorporated homes south of Willow attend South. Two properties carrying similar Glenview postal labels can lead to different schools because their incorporation or annexation status differs.

Glenbrook Off Campus is a small, specialized environment for students who face challenges in a larger setting. It provides academic instruction, social-emotional skill building, and transition planning; it has no neighborhood attendance area.

Glenbrook Transition Services serves young adults with disabilities ages 18–22 through job readiness, life skills, and community-based instruction after their high-school programs. North and South remain the only geographic high-school assignments. Off Campus and Transition Services are distinct educational settings entered through student needs, not through additional lines on the residence map.
