There are many opportunities for our Crespi Celts to engage in co-curricular activities. Clubs and activities offered through Student Life allow our boys to gather together on common interests that satisfy their intellectual curiosity and need for exploration. With two students and one faculty moderator, a club can start off small and grow to new heights. Some activities have expanded to more formal programs.

For any questions regarding a particular club or activity, please contact the moderators listed below.

    Academic Decathlon is the pinnacle of academic competitions. Teams of nine students compete in regional competitions each winter with the hope of advancing to state and then national championships.

    3. Science
    4. Music
    5. Economics

    The highlight of competition day is the Super Quiz during which teams occupy seats on the floor of a gymnasium or stadium and fans cheer on the live score that tracks their correct responses. 
    Crespi Academic Decathlon competes in the Southern California Private Schools Academic Decathlon, participating in a 1-day scrimmage in November and the 2-day regional competition on the last Saturday in January and the first Saturday in February.

Students build autonomous and human controlled machines that perform a specific task that engages in the engineering design cycle using multiple prototypes and iterations. Actively participating in VEX competitions throughout the year, this program prepares students for future college endeavors in STEM. 
  • STEM Cohort Program

    Moderator: Dr. Brahim

    Qualification Requirements:
    All students at Crespi receive a STEM education once enrolled in our STEM (Science, Technology, Engineering, and Math) courses. Students who test highly on the HSPT and the Math and Science Placement Exams will be invited to join the STEM Cohort. Students who did not qualify may apply at the end of either semester of their Freshman year. These students must collect letters of recommendations from both their science and math teachers commenting on their grades, attitudes, interest level, and work ethic.
    Grade GPA Requirement:
    Students must maintain a 3.0 Average in their Math/Science Courses without receiving any grade lower than a B- in Math or Science. If a student’s cumulative GPA drops below 3.0, the student will be placed on probation for a semester. The student will be encouraged to drop all extra curricular activities, including STEM work until they have shown improvement on the first progress report of the probationary semester.

    Research Requirement:
    Members of the STEM Cohort will be required to work on a competitive STEM-based project. Students must submit their completed projects to relevant competition organizers by the due deadline with the permission and approval of a STEM teacher.
    The project requirements, group participants, and submission deadlines are very diverse with many options to choose from. A research project can be and is encouraged to be, part of a larger study performed by professional scientists, but the project presented by the students must be only their own portion of the complete study.

    Students will spend their first three years in the STEM Cohort on their research requirement. During their freshmen year, students will research project ideas and explore potential interest areas and develop a proposal for their research requirement.

    It is encouraged that a bulk of their project be performed during their sophomore year so this provides them an extra year to apply for science fairs during Junior year.

    STEM Cohort members during the Senior year will focus on mentorship for the younger students. Mentors will be paired with a younger student or student group and will guide them through the process of submitting to a science fair.
