Student Organizations

For more than 100 years, San Marcos Academy has provided a distinctive leadership development program rooted in the values, traditions, and discipline of the United States military. Through the SMA Corps of Cadets, students develop character, responsibility, self-discipline, and servant leadership while participating in a structured environment that encourages personal growth and accountability.

Upper School cadets enroll in credit-bearing Military Leadership courses that follow the curriculum of a Junior ROTC program. These courses are taught by LTC David Jaillite, U.S. Army (Ret.), former Director of the U.S. Army Logistics University. Students earn Junior ROTC credit on their transcripts and may be recommended for appointments to United States military academies. Whether pursuing military service or civilian careers, cadets gain leadership skills and life experiences that prepare them for success beyond graduation.

The Student Council serves as the voice of the student body and promotes active student involvement in the life of San Marcos Academy. Through collaboration with school leadership, Student Council members advocate for student interests, provide valuable feedback, and help foster a positive school culture.

Student Council also plans and coordinates a variety of campus events, activities, and service projects that strengthen community and school spirit. Through leadership opportunities and hands-on experience, members develop communication, teamwork, problem-solving, and servant leadership skills that prepare them to make a meaningful impact both on campus and beyond.

The Robotics program challenges students to apply science, technology, engineering, and mathematics (STEM) concepts through hands-on design, building, and competition.

Through Robotics, students cultivate creativity, critical thinking, teamwork, and technical skills that prepare them for future academic and career opportunities.
