History Banner


Our philosophy reflects the basic beliefs about learning and teaching in Antonian's educational environment. To this end, there is a set of principles that are required to be endorsed by all members of the Antonian community. These principles form the Antonian Core Values and include:


  • Compassion
  • Courage
  • Integrity
  • Justice
  • Love
  • Responsibility
Antonian was established in 1964 by the Archdiocese of San Antonio with the support of the pastors from twelve northside parishes and was originally staffed by the Brothers of the Christian Schools.

Antonian retains many of the innovative practices attributed to St. John Baptiste De La Salle, including the integration of religious instruction with academic subjects, well-prepared teachers with a sense of vocation and mission, and the involvement of parents. Originally a school for boys, Antonian transitioned to being a co-educational school in 1989.


Preparing students academically, socially, and emotionally for higher education and life demands an environment reflective of the real world. The real world is comprised of men and women, and Antonian graduates are prepared to interact and work with members of the opposite sex both in college and classrooms and in the workplace. This Antonian dynamic empowers students to grow as both individuals and members of the community.


The mission of Antonian College Preparatory High School is to inspire and empower young men and women to thrive while leading meaningful lives rooted in the teachings of Jesus Christ.


Influenced by our LaSallian legacy and animated by our desire to see God in all things, Antonian College Preparatory will continue to be a premier Catholic, co-educational high school. We encourage our students to always seek knowledge and to deepen their relationships with God to make a positive difference through service to others. We empower and inspire our students to embrace opportunities to work with integrity for peace and justice in our ever-changing world.
