Student – Teacher Progressive Discipline

In an effort to provide a safe learning environment with consistent and fair practices in our abbreviated schedule we have developed the following practice for students with behavior concerns:

  1. Warning to student
  2. Student -Teacher conference with parent follow up
  3. Contact an MBX administrator and tardy assigned


Only students entering grades 9 – 12 in the fall may take courses for academic credit.

The academic requirements and policies of the MBX Summer School Program are presented on this website. Please review them carefully. YOU ARE RESPONSIBLE FOR KNOWING AND COMPLYING WITH THESE REGULATIONS.

ACCELERATED PROGRAM: One day of class is equivalent to a week of classes during the regular school year. Failure to attend class regularly jeopardizes your chances for academic success.

TEACHER ASSIGNMENTS: Teacher assignments will be posted in Aeries on the Friday prior to the first day of class. Teacher change requests will not be granted.

MBX provides a high-quality, rigorous program for initial credit as well as remediation. A full year course curriculum is condensed to 24 days and a semester course curriculum is completed in 12 days. Attendance is critical not only for success, it is required for course credit.

Attendance and Tardy Policies

  • One Absence Per Semester:
    • An absence is defined as missing ONE day of class or equivalant of late/tardies,
      • Distance Learning classes meet twice daily.
      • Distance Learning Health classes meet once daily for approximately 1 hour.
  • Tardy Policy:
    • More than 15 minutes late counts as an absence
    • Four tardies (more than 5 minutes) counts as an absence
      • Teachers will document all infractions and communicate with families early shall a negative pattern emerge 
  • Last Day Policy: The last day of each semester is a mandatory day, meaning all students must attend (Friday, 7/7 and Thursday, 7/27) 
  • More than 2 absences in a semester: Students will be dropped from the course with be given no credit and no refund
  • Last Day Absence: Students who miss the last online session of either Semester 1 or 2 will be given no credit and no refund

Attendance Policy – Athletic

Some athletic programs may be taken for PE credit. Please see the Athletic/Activity page for more information. Athletic activities taken for credit earn 5 high school PE credits. To obtain credit for the semester you may not have more than one absence from an assigned workout.  If more than one day absence is anticipated, please inform the activity coach and no credit will be awarded.

Course Credit (Academic)

MBX is a WASC accredited supplemental education program.  All MBX academic courses are accepted for credit on Mira Costa High School transcripts.

Each semester course is equivalent to 5 high school credits. Successful completion of yearlong courses earns 10 high school credits.

All MBX academic courses are eligible for UC/CSU approval and meet A-G subject requirements once placed on the Mira Costa transcript through Principal Certification (As described by UC Admissions)

If you attend a high school other than Mira Costa, you are responsible for ensuring that your grade will be accepted on your home school transcript and will subsequently meet the A-G subject requirement.


Students will be required to have WIFI and a device such as a laptop, chrome book or notebook computer (a cell phone will not be sufficient). If you do not have one, you may borrow a ChromeBook from MBX. Please reach out to Kathy Duffy () for more information.

Homework should be purposeful and related to the subject studied. It is intended primarily to give the student added practice in acquiring skills, insights, and understanding in a particular area of learning. Nightly homework requirements vary among classes and teachers. If a teacher does not provide a specific assignment, it is expected that students read, study or review for the class each night.

Make Up Exams
If you miss an exam or other required course work during the summer session because of absence, you may make up the exam or assignment within one day of returning to school. Arrangements to complete make-up work are your responsibility and must be made directly with your instructor. All work must be completed by the last day of classes (2PM on 07/27/2023). There are no make-up days for final exams, nor may they be taken early. Instructors may not authorize exceptions to this rule. Any extenuating circumstances will be handled by the principal, no later than the last day of class.

Grade Reports

Grades in courses taken at MBX are automatically placed on the Mira Costa transcripts for Mira Costa students. Any student who does not wish to have his/her grade on their Mira Costa High School transcript must ask their parent to request this by August 4, 2023 at 4:00 pm by emailing

If you are not a full time Mira Costa High School student, please email to request a transcript. Please email the student name, school name and address for the sealed transcript to be sent.

Grade discrepancies must be reported immediately to the Summer School Principal. The appeal or challenge deadline for disputed grades is forty five days after the closing of classes. No changes, adjustments or corrections will be made after that date.


You may not enroll in a course for which you do not have the prerequisite or its equivalent. Prerequisites are listed in the course descriptions. Instructors may not waive prerequisites within a department sequence and accept students into the next level. Please note the differentiation between original credit courses and review courses. Review courses require that the course has already been taken during the regular school year. Original credit courses have a prerequisite noted if applicable. Since the Summer School does not have access to the student’s grades, please ensure that the course prerequisite is met or consult your educational advisor.

Note: Certain Activities/Physical Fitness courses have tryouts. These are listed in the various course descriptions if available.

Program Withdrawals

You may request a course withdrawal by completing and completing a Course Withdrawal Form

Course changes must be made on or before noon on the third day of the semester.

If a withdrawal is requested prior to June 1, 2023, full refunds will be granted less a 10% administration fee. After June 1, 2023, partial refunds (60%) are granted if the course, including a review (remedial) class, is dropped by the student before the first day of class. This requires PARENT EMAILED notification of the intent to drop/withdraw received no later than noon on the first day of class. No refunds of either tuition or fees will be issued after the first day of class.

Please note that if a student withdraws from a FLEX class of 2 or more students, the remaining students will be responsible for the higher tuition if the partner is not replaced.


Need based scholarships are available for academic classes. Please consult your MCHS school counselor for more information.
