Welcome to St. Mark’s School of Texas. Founded in 1906 as the Terrill School for Boys with 42 students, today we serve more than 900 boys in grades one through twelve. 
As a school focused clearly on the education of boys, our teachers, coaches, and advisors understand and appreciate the unique nature of boyhood. With challenging programs designed to inspire, motivate, and stretch our students, St. Mark’s is a place where boys can be themselves, develop respect for others, and learn what it means to be a man of true character and integrity. Our mission at St. Mark’s is clear – we seek to develop men of character who will serve with intelligence, compassion, and integrity. 
During the past three decades at St. Mark’s, I have developed a profound appreciation for and love of our students and teachers. While excellence and achievement are prevalent in programs and activities across the campus, it is the character of the people that defines our School – faculty who care deeply about their charges and students who give freely to one another to continually strengthen the sense of community. Courage and Honor are two words commonly used to describe the ethos of our campus. As the School motto, these terms remind us what values underpin our mission and daily work. 
If you visit our school you will quickly see that we have some of the strongest academic, athletic, artistic, and extracurricular programs imaginable. Our boys learn from teachers who are not only leaders in their fields, but are also individuals who truly love their work. St. Mark’s is a community that works together and is driven by a common purpose.  
I hope you find this website helpful and informative. At the same time, there is no substitute for visiting our campus and seeing our teachers and students in action. We look forward to welcoming you to St. Mark’s sometime soon.

From the Statement of Purpose

St. Mark’s aims to prepare young men to assume leadership and responsibility in a competitive and changing world. To this end, the School professes and upholds certain values. These values include the discipline of postponing immediate gratification in the interest of earning eventual, hard-won satisfaction; the responsibility of defending one’s own ideas, of respecting the views of others, and of accepting the consequences for one’s own actions; and an appreciation for the lively connection between knowledge and responsibility and the obligation to serve.
