St. John XXIII College Preparatory is an independent co-educational Catholic high school located in the greater-Houston suburb of Katy, Texas.  Founded in 2001, we strive to form the hearts and minds of young men and women in a Christ-centered community dedicated to academic excellence, the pursuit of virtue, and service to others in the Tradition of the Catholic Church. Our mission rests on Four Pillars which reflect the papacy of our patron, Pope St. John XXIII, and the transformative spirit of the Second Vatican Council which he convened in 1962.   

Oboedientia – Learning to trust the voice of God  
Pax – Experiencing God’s peace through liturgy  
Virtus – Forming character that leads to virtuous action  
Renovatio – Renewing the Church and the world  

We accomplish our mission through our rigorous academic study and faith-filled Campus Ministry program. Our House System, established in 2011, fosters relationships among our students and allows opportunities for our faculty mentors to promote virtuous living. The houses also provide the framework for student government and ample opportunities for students to explore their leadership skills and abilities. 

The Center for New Evangelization, which houses our dynamic Campus Ministry program, is committed to playing a vital role in forming the hearts and minds of our students by providing occasions to encounter Christ through the Liturgy, our Retreat Program, and our Works of Mercy service program.  

At SJ23, competitive athletic programs offer every student the experience of being a part of a team, forming them into men and women of character. In addition, our Performing Arts program features the talents of students and faculty working together to achieve a particular vision through various media – on the stage and in music, through pen, paint, paper, and photography.  

Finally, as a support for our rigorous curriculum, the Learning Center offers specialized instruction for students requiring additional attention to unlock their God-given potential in keeping with our mission.  

St. John XXIII believes that by providing our students with all they require to flourish and become disciples of Jesus, we are truly tending to God’s flock. St. John XXIII College Preparatory strives to be an instrument in the Church’s overall mission of evangelization in the spirit of our patron Pope St. John XXIII.
