What St. Mark's School of Texas does
St. Mark's School of Texas is a private, nonsectarian college-preparatory boys' day school founded in 1906 and located at 10600 Preston Road in Dallas, Texas. The school enrolls 924 students in grades 1 through 12 across three academic divisions — Lower School (Grades 1-4), Middle School (Grades 5-8), and Upper School (Grades 9-12) — and serves families in the Dallas-Fort Worth metroplex seeking a rigorous private education. Its academic offerings are supplemented by a comprehensive slate of programs including fine arts (band, choir, ceramics, drama, film studies, orchestra, painting & drawing, photography), competitive athletics, outdoor education, student publications, college counseling, and a dedicated Character & Leadership Education program anchored by the TELOS Mentorship model.
The school generates revenue primarily through tuition and fees billed on an annual cadence, supplemented by philanthropic streams — notably the St. Mark's Fund (annual unrestricted giving from alumni, parents, and friends), planned giving through the Terrill Society, and endowment contributions. The St. Mark's Fund alone reached $5.3M+ in fiscal 2022 and represents 10% of the school's operating budget, implying an aggregate operating budget in the range of $50M+. Tuition rates are not publicly disclosed and must be quoted directly, with financial aid available for qualified families. The go-to-market is direct-to-consumer, relying on admission events, campus tours, word-of-mouth from current families, and the strength of a 4,000+ alumni network organized into regional clubs in major U.S. cities.
Operational infrastructure includes a MySchoolApp student information system, SAGE Dining food services, and a recently expanded campus following the 2025 dedication of the Zierk Athletic Center and Albert G. Hill Sr. Family Tennis Center — the largest single capital development in school history — and the January 2026 conversion of the former Rogers Natatorium into the Ralph B. Rogers Family Fieldhouse. The school is governed by an independent Board of Trustees as a 501(c)-equivalent nonprofit institution, with no parent company, external ownership, or M&A activity.

St. Mark's School of Texas competitors and assessment
Company assessmentRegional players
- Casady School: Independent college-preparatory day school (PK-12) in Oklahoma City. Comparable as a regional independent day school with similar college-counseling focus, character education, and tuition-supported operating model in a non-Dallas metro.
- St. Andrew's Episcopal School: Independent college-preparatory day school (K-12) in Austin, Texas. Comparable as a Texas-based independent school with similar academic-rigor positioning and Episcopal heritage, though it serves a different metro from St. Mark's.
- Parish Episcopal School: Independent college-preparatory day school (PK-12) in Dallas, Texas. Comparable as a Dallas-area private school competing for similar North Texas families, with co-ed programming that differentiates from St. Mark's boys-only structure.
Direct peers
- The Town School: Independent boys' day school (K-8) in New York City with similar mission, leadership programming, and nonprofit governance structure to St. Mark's lower and middle divisions.
- The Browning School: Nonsectarian independent boys' day school serving grades K-12 in New York City. Directly comparable to St. Mark's in mission, single-sex structure, elite college-prep focus, and family-funded tuition model with annual giving campaigns.
- The Buckley School: Elite nonsectarian boys' day school (K-9) on the Upper East Side of Manhattan. Closely mirrors St. Mark's character-education emphasis, academic outcomes orientation, and tuition-discretion positioning.
- University School: Independent boys' day school (K-12) in Shaker Heights, Ohio. Comparable as a nonsectarian boys' school with a similar academic-rigor profile, alumni-driven fundraising culture, and tuition-disclosed model.
- Allen-Stevenson School: Nonsectarian independent boys' day school (K-9) in New York City. Comparable as another elite boys' school with strong character-development programming, distinguished alumni network, and premium tuition model.
Broad incumbents
- The Hockaday School: Elite private girls' day school in Dallas with which St. Mark's co-produces drama productions and Model UN. While not a direct admissions competitor, Hockaday is the natural counterpart institution for Dallas families and competes for the same donor and faculty pool.
- Greenhill School: Elite private co-educational day school in Addison (Dallas), Texas. Direct competitor for top Dallas-Fort Worth families and admissions mindshare; broader grade-span and co-ed model positions it as the primary local incumbent alternative to St. Mark's.
