About Business and Technology

Glenbrook High School District 225 has been recognized by the International Association of School Business Officials and the Government Finance Officers Association for excellence in financial reporting. Additionally the District has received the highest bond ratings available from both Moody's Investors Services (Aaa) and S&P Global Ratings (AAA). The Business Services department is responsible for the development and management of the District's $160 million budget in partnership with the Board of Education.

Our District's Technology Services department oversees the day-­to-­day and long-­term strategic plan for the District's operational technology program. Glenbrook serves as the lead agency for the Northfield Township Technology Consortium, a shared services inter-­governmental agreement providing students and local government agencies access to 20 GB of internet bandwidth for a modest cost. Students, parents, and staff members are encouraged to contact the Glenbrook Technology Help Desk at 847.486.­4555 or via e­mail at with any questions about our services and systems, including PowerSchool.
