Building Administration

The day-to-day operations of Glenbrook North High School are overseen and managed by the Principal and a group of highly-qualified school administrators.

School administrators are responsible for:

  • Leading and overseeing the operations of one or more functional areas of a school or District department
  • Directly supervising and evaluating personnel
  • Responsible for serving as a budget manager for a functional area 
  • Ensuring compliance with local, state, and federal laws

Glenbrook High School District 225 employs licensed administrators (individuals filling positions requiring licensure from the Illinois State Board of Education) and non-licensed administrators (filling positions that do not require licensure).
