Summer School

Each year Glenbrook High School District 225 offers a summer school program for students who want to earn credit in core academic areas, recover credit for a course previously taken, or participate in enrichment courses. Enrollment in summer school is optional, tuition-based, and requires parents to complete the registration process.
