About St. Mark’s
Founded in 1906, St. Mark's School of Texas is a non-sectarian, college-preparatory, independent day school for boys in grades one through twelve. The School’s charter states that it is “designed to afford its students well-rounded physical, intellectual, moral, and religious training and instruction.” The School is intended to be a diverse community of teachers and students who share a love of learning and who strive for high achievement in whatever they undertake.
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 interests 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.
