St. Mark’s School of Texas: Serious Opportunity, Serious Work, and a Boys-School Culture to Test Closely

Visits

Useful access, without a demonstrated-interest penalty

Lower School open house is October 14, 2026. The Grades 5–11 open house is October 28.

Parent coffees include tours, while family campus tours last about one hour.↗

Admission events are optional and do not affect the application. That statement should lower pressure to attend everything, although required observations and interviews remain part of the file.↗↗↗

Visit strategy — watch who speaks, who gets redirected, and how adults handle mistakes. Ask students about a normal class day, not only favorite traditions or extraordinary achievements.↗↗

Boys-school model

Character formation is explicit, not background branding

The school frames its purpose around preparing young men for leadership and responsibility. Character and Leadership education runs across Grades 1–12 through head, heart, and hands: engagement, service, and leadership.↗↗

This philosophy becomes visible through advising, service, athletics, chapel, wilderness trips, traditions, and a Path to Manhood portfolio. Families are choosing a formation model, not only single-sex classrooms.↗↗↗↗

Our read — a boys’ school can create uncommon friendship and permission to participate broadly. It can also narrow belonging when athleticism, confidence, heterosexuality, or conventional masculinity become unstated defaults.↗↗↗

Current gap — the public nondiscrimination language names sexual orientation, but not sex, gender identity, gender expression, or disability. That omission does not prove practice, but it warrants direct questions.↗↗

Faith and chapel

Nonsectarian does not mean religion-free

St. Mark’s is nonsectarian and historically Episcopal.

An Episcopal priest serves as chaplain. Weekly chapel in every division uses music, sacred literature, congregational prayers, and student or guest talks.↗↗

Chapel marks Christian, Jewish, Muslim, Hindu, cultural, and school observances. The stated goal is spiritual and moral formation through traditions represented in the community.↗

The published chapel schedules do not match: the spiritual-life page says chapel is weekly in every division, while the Lower School curriculum says boys attend twice weekly. Ask which schedule governs 2027–28.↗↗

Fit question — families should hear an ordinary chapel, not only read the inclusive description. Ask what attendance, prayer, speaking, singing, and reflection require from students who are religious, questioning, or nonreligious.↗

Academics

Breadth begins early, while advanced choice grows later

Lower School includes language arts, mathematics, science, social studies, Spanish, fine and performing arts, physical education, and computer science. Spanish and specialist-rich study begin in Grade 1.↗↗

Middle School requires sequenced humanities, language, mathematics, and science. Fine arts appear at every level, alongside daily physical education or athletics.↗

Upper School uses Harkness discussions, seminars, tutorials, coordinate classes, traditional requirements, electives, service, and athletics. The school does not rank students and limits schedules to six courses per semester.↗↗

New Upper School students generally do not enter Honors or Advanced Placement courses immediately, although they may petition. Departmental criteria control placement, and the broadest advanced choice begins in junior year.↗↗

Transition question — later entrants join established mathematics, language, writing, advising, service, and wilderness sequences. Ask for a written placement plan before accepting a Grade 6 or Grade 9 offer.↗↗↗

Assessment and workload

The Middle School numbers deserve to be taken literally

Grades 5–6 can expect 20–30 minutes of homework per academic subject nightly, plus an outside-reading book every two weeks. The school advises reserving several hours each day.↗

Grades 7–8 can expect 30–40 minutes per academic subject nightly. Study hall can reduce evening work, but the published estimate still signals a demanding baseline.↗

Middle School tests normally require three days’ notice, with no more than two per day. Major tests can cluster near trimester ends, and Grade 8 May exams carry 10%–20%.↗

Teacher comments report progress throughout Middle School. Grades are added in Grades 7–8.

Eligible students with strong averages can earn study-hall release.↗

Upper School uses an unweighted 4.0 scale and adds weighting for Honors and Advanced Placement work. Advanced Placement exams are optional, but each course requires a culminating assessment.↗↗

Upper School publishes no typical homework hours, assessment ceiling, grade distribution, revision rules, late-work rules, sleep data, or course-level withdrawal counts. Ask for current, grade-specific evidence.↗↗

Academic boundaries

Support exists inside a school willing to say the fit can fail

Middle School directs struggling students first toward teachers. It may recommend outside tutoring or diagnostic testing.

Some boys must complete summer courses, and occasional grade repetition occurs.↗↗

The Middle School policy says re-enrollment may be withheld when the environment seems too strenuous. It publishes no annual count, grade pattern, aid pattern, or exit outcome.↗

Upper School course changes tighten after five or ten class days. Later withdrawal is rare and can produce a withdrawal-pass or withdrawal-fail notation.↗

ask what happens before the school reaches a fit decision. Request real examples involving workload reduction, summer work, repeating, leave, accommodations, outside tutoring, and non-renewal.↗↗↗

Support and wellness

A real team, with an explicit short-term boundary

Each division has a dedicated behavioral-health provider. The center offers family and student counseling, screening, parent consultation, outside referrals, and coordination with community providers.↗

School counseling is short-term and temporary, aimed at acute distress and school functioning. The school states that it cannot replace comprehensive, long-term psychotherapy.↗

Academic services include screening, psychoeducational referrals, assessment review, Individual Learning Plans, and disability-accommodation coordination. Examples include 50% extended time, laptops, notes, and preferential seating.↗

Current boundary — a physician’s diagnosis alone is insufficient for academic accommodations. The school requires a full psychoeducational assessment, whose outside cost and renewal schedule are not public.↗

Provider caseloads, session limits, response times, crisis coverage after hours, accommodation rates, outside-assessment aid, and profiles the school cannot serve are unpublished.↗

Culture and belonging

Strong identity can create both brotherhood and pressure

The school reports 53% students of color and supports a student-led Inclusion and Diversity Leadership Council. It also describes workshops, dialogue, and a multicultural night.↗↗↗

The dress code is traditional and specific. It requires oxford shirts and gray bottoms, restricts hair and facial hair, and prohibits earrings, tattoos, dyed hair, ponytails, and man buns.↗

Prior school evidence — a 2023 article introducing Telos acknowledged earlier bullying, discipline problems, and weak older-younger relationships. It described a student-led effort to build cross-grade culture.↗

Attributed reviews — Niche’s 100 self-selected reviews are mostly positive but sharply mixed on pressure, collaboration, bullying, racism, antisemitism, and support. Anecdotes identify questions; they do not establish prevalence.↗

Niche polls are similarly small. Twenty-one respondents produced an 81% safety result and a 76% happiness result.

Twenty-six respondents overwhelmingly described students as competitive, athletic, and hardworking.↗

The school publishes no current climate, bullying, discipline, retention, exit, or belonging data by race, religion, sexuality, disability, grade, or financial-aid status.↗↗

Arts, athletics, and outdoors

Breadth is credible, but access and time remain the test

Students encounter art from Grade 1. The school lists 54 fine-arts courses spanning design, woodworking, ceramics, band, choir, drama, film, orchestra, drawing, painting, and photography.↗↗

Athletics lists 16 sports and 46 varsity teams. The school says 85% of Upper School students play at least one sport annually.↗

School-sponsored competition begins in Grade 7. Grades 1–6 use parent-volunteer community leagues, making availability and family labor different from a school-run team program.↗↗

Wilderness education is required from Grade 6 through the summer before Grade 9. Every Grade 9 entrant must complete the ten-day Pecos trip unless exceptionally excused.↗↗

Current incident — the 2026 Pecos trip ended early because of nearby forest fires. The school presented the trip positively but published little operational detail about evacuation or medical decision-making.↗

Participation does not establish equal access, meaningful choice, playing time, cast or team cuts, late transport, or manageable scheduling. Ask how arts, athletics, and academics collide in a normal week.↗↗↗

Commute and daily life

The Preston Road day is built around family driving

The campus sits at 10600 Preston Road in Preston Hollow. The campus page calls it roughly 40 acres, while other school material has used 42 acres.↗↗

Lower School opens at 7:35, with classes from 7:55 until 2:50. Middle and Upper classes run from 8:30 until 3:25.↗

St. Mark’s does not provide transportation.

Families must drive or arrange carpools across a wide metropolitan area. Model rush hour, multiple children, practices, performances, and away games.↗↗

Lower School after-school care runs until 6:00. Public pages do not state its price, enrollment cap, closure dates, food, homework support, pickup penalties, or aid coverage.↗

No comparable Middle or Upper supervised-care option is published. Late buses, activity shuttles, carpool matching, and transportation after away events are also unclear.↗↗

Discipline and controversy

One court record raises process questions, not a verdict on culture

Prior independent record — a family sued after an Upper School student received a zero on an Advanced Placement Statistics final following an alleged cheating incident. The school maintained that cheating occurred.↗

The 2023 appellate court voided an emergency order for procedural defects. It did not decide whether the student cheated or whether the school’s academic decision was correct.↗

Reporting limit — we did not find a final public merits resolution. This record supports questions about notice, evidence, appeal, parent access, transcript effects, and independent review, not a broad allegation.↗↗

Tuition and full cost

Tuition varies by grade, and the complete bill is not public

2026–27 tuition runs from $33,432 in Grades 1–2 to $42,697 in Grade 9. Grade 6 is $37,346, and Grade 12 is $41,856.↗

Fall 2027 tuition is not published. The live At A Glance page lists $36,720 average tuition including books and fees, but that figure sits below several current grade prices.↗↗

Current costs — Grade 1 testing is $475, Grade 4 testing is $510, and Grades 5–11 ISEE testing is $165 or $240. The school application itself is free.↗↗

Grades 5–12 require a laptop. Uniforms and physical-education clothing are required.

Lower supplies are provided, and Grades 5–12 textbooks ship home.↗

Price aftercare, lunch, uniforms, laptops, wilderness gear, travel, tutoring, arts supplies, athletic equipment, parking, and late pickup. The public site does not provide one realistic all-in annual budget.↗↗↗

Current culture — the school reports 86% parent participation in its 2024–25 annual fund. That is not a mandatory charge, but it signals a visible philanthropic norm families should understand.↗

Financial aid

Substantial resources, with important missing household detail

Applicant aid files are due February 15, 2027 through Clarity. The application costs $60.

The school says asking for aid does not affect admission.↗

St. Mark’s reports more than $4 million in annual assistance and an average grant above $21,000.

Roughly half of grants go to families earning above $175,000.↗

Families below $140,000 receive an average $35,639 award. The school says it funds about 90% of tuition on average for this income group, not every family’s full calculated need.↗

More than $150,000 in supplemental aid supports tutoring, technology, travel, wilderness, arts, and athletics. Ask how families request it and whether awards arrive with the enrollment decision.↗

Recipient count, need-met percentage, award timing, appeal rules, noncustodial-parent rules, home-equity treatment, tuition-growth protection, and aid retention are not public.↗

Entry points

No Kindergarten, four larger doors, and several narrow ones

St. Mark’s begins in Grade 1, so Kindergarten is not an entry point.

A Grade 1 applicant must attend Kindergarten or Primer during fall 2026.↗↗

Recent annual admission averages are 32 in Grade 1, 18 in Grade 4, 22 in Grade 5, and 20–25 in Grade 9. These are the clearest structural openings.↗

Grade 6 and Grade 7 each average 6–8 admissions. Grade 8 averages 4–6.

Grades 2 and 3 average two each, making eligibility very different from a broad entry year.↗

Grades 10 and 11 accept students based on attrition. The public admissions menu stops at Grade 11.

Families should treat Grade 12 as unavailable unless the school confirms otherwise.↗↗

Averages do not reveal Fall 2027 seats, applications, offers, yield, aid requests, sibling priority, legacy treatment, or employee-child preference. They describe recent intake, not an applicant’s odds.↗

Selectivity

The published percentage is historical and denominator-light

The FAQ says 15% of applicants were admitted in recent years. The live At A Glance page says 16% acceptance and 90% yield, without naming a cycle.↗↗

The school’s two published admit rates, 15% and 16%, may reflect rounding, timing, or different cohorts. Neither page provides applications, offers, grade distribution, aid status, or returning-family context.↗↗

Use the grade-level admission averages before the schoolwide percentage. A Grade 2, Grade 6, or Grade 10 family faces a different seat structure from a Grade 1 applicant.↗

Grades 1–4

Observations and substantial outside testing start early

Grade 1 applications are due December 14, 2026. Parent responses, CATS cognitive testing, virtual ATS achievement testing, observations, records, and the current teacher evaluation are due January 29.↗

Grade 1 testing costs $475 before any waiver. CATS costs $325 and ATS costs $150.

Reduced CATS pricing and ATS assistance may be available.↗↗

Grades 2–3 applications are due November 9. Their remaining files are due December 14 and include ISEE Primary, an on-campus observation, records, a teacher evaluation, and a parent response.↗

Grade 4 follows the November 9 application deadline but requires both CATS and ISEE Primary. Published testing costs total $510 before assistance.↗

The school describes observations as classroom activities with other applicants and Lower School teachers. It does not publish the rubric, exact duration, accommodations, parent role, or weighting.↗↗

Grades 5–11

One core file, three interview options, and no application fee

Applications for Grades 5–11 are due January 8, 2027. Parent and student responses, activities, ISEE results, interviews, records, and English and mathematics recommendations are due January 29.↗

ISEE costs $165 in person or $240 at home. Testing assistance is available.

St. Mark’s charges no school application fee.↗↗

Applicants choose an afternoon campus interview, a shadow visit with interview, or a virtual interview. The conversation includes peers and a faculty member.↗

Dallas–Fort Worth applicants are encouraged to interview in person. Out-of-area applicants, or those unable to visit, are encouraged to use the virtual option.↗

No public page gives interview length, questions, scoring, parent-interview expectations, writing prompts, accommodations, or relative weight. It also omits the family reply deadline and waitlist process.↗↗
