Three ways to take an MBX academic course. All three earn credit on a Mira Costa transcript.
MBX is excited to offer in-person classes on the Mira Costa High School campus, Monday–Thursday, June 22 through July 30. Hours are 8:30am–2:00pm and students must attend daily. Classrooms are assigned the week prior to the start of classes.
MBX Foundation has partnered with an online learning courseware to offer self-paced courses that are standards-aligned, interactive and media-rich. Students work at any time between June 22 and July 30, and all finals must be taken in person at MCHS. Grades may not be finalized on the last day of the semester.
Students needing to remediate a class previously taken can use our online learning platform. Students may only retake a class if they earned a D or F — please do not register until you know your student’s final grade.
Student athletes meet in cohorts on the Mira Costa campus. Please note athletics may have a different schedule
from academic summer school due to CIF rules.
