MBX Summer School

2026 MBX Summer School Registration

MBX Summer School registration opens on March 12, 2026.
Enrollment is open to incoming 9th graders and all high school students, both in and out of the district.

Students can earn academic initial credit or complete credit recovery, free up space in their school-year schedules for electives, advanced classes, or other interests, and meet summer athletic training recommendations. Accredited courses are offered in both in-person at the familiar Mira Costa High School campus or on our online platform, providing a flexible and supportive learning environment.

Enrollment helps support MBUSD school facilities and enrichment programs.
