Top 10 Catholic Schools in Missouri in 2027

1. St. Louis University High School

St. Louis University High School ranks first for combining the deepest academic pedigree in the state with the broadest college-placement track record. Founded in 1818 and run by the Jesuits, it is one of the oldest schools west of the Mississippi River, operating from its Oakland Avenue campus in St. Louis. Its all-boys curriculum blends AP coursework, retreat programs, and a alumni network reaching into St. Louis's civic and business leadership.

This school suits families prioritizing a rigorous, historically Jesuit college-prep track over a smaller or newer alternative. Tuition and an all-male, single-sex format are real trade-offs versus coed options further down this list. Compared to Rockhurst below, SLUH draws more heavily from the St. Louis metro rather than Kansas City, making geography the main deciding factor between the two.

2. Rockhurst High School

Rockhurst High School ranks second as the Kansas City counterpart to SLUH, delivering the same Jesuit, all-boys model with a founding date of 1914. Located in Kansas City, Missouri, it anchors college-preparatory education on that side of the state and maintains close ties to Rockhurst University next door. Retreats, service requirements, and Advanced Placement offerings mirror the Jesuit network's shared academic framework.

Families based in the Kansas City metro who want the Jesuit model without relocating toward St. Louis are the clear fit. Like SLUH, its all-boys structure and private tuition narrow the applicant pool relative to coed schools further down this ranking. Against Chaminade below, Rockhurst offers the Jesuit order specifically, versus Chaminade's Marianist tradition.

3. Chaminade College Preparatory School

Chaminade College Preparatory School ranks third on the strength of its Marianist educational tradition, founded in 1910 and now based in Creve Coeur in St. Louis County. As an all-boys school run by the Society of Mary rather than the Jesuits, it offers a distinct religious-order identity while still competing academically with the two Jesuit schools above it. Its suburban St. Louis County campus draws heavily from west county communities.

This pick fits families who want Marianist rather than Jesuit formation, or who live closer to St. Louis County suburbs than the city campuses above. The trade-off is a smaller historical footprint than SLUH's two-century record. Compared to De Smet below, both are Catholic all-boys St. Louis County schools, but Chaminade is Marianist while De Smet is Jesuit.

4. De Smet Jesuit High School

De Smet Jesuit High School ranks fourth as St. Louis County's dedicated Jesuit option, founded in 1967 and located in Creve Coeur. It gives families west of the city a Jesuit, all-boys education without commuting into St. Louis proper, following the same order and college-prep structure as SLUH. Its relatively recent founding compared to SLUH's 1818 date reflects the mid-century growth of Catholic education in the county.

De Smet suits county-based families wanting Jesuit formation locally rather than a downtown commute. It trades SLUH's longer institutional history for closer proximity to west-county neighborhoods. Against Christian Brothers College High School below, the distinction is Jesuit versus Lasallian (Christian Brothers) sponsorship, a meaningful difference for families with an order preference.

5. Christian Brothers College High School

Christian Brothers College High School, known as CBC, ranks fifth on the basis of an 1850 founding date, making it one of the older Catholic schools on this list, now based in Town and Country, Missouri. Run by the De La Salle Christian Brothers (Lasallian order), it is an all-boys school with a long-standing St. Louis-area alumni base distinct from the Jesuit schools ranked above it.

CBC fits families seeking Lasallian rather than Jesuit or Marianist sponsorship, with a similarly long institutional history to SLUH. The single-sex, private-tuition format remains a shared trade-off across this tier of schools. Compared to Vianney below, both serve St. Louis County boys, but CBC's Lasallian identity and older founding date set it apart from Vianney's Marianist, 1960s origin.

6. Vianney High School

Vianney High School ranks sixth as a Marianist, all-boys school founded in 1960 in Kirkwood, Missouri, within St. Louis County. Its mid-20th-century founding places it among the newer schools on this list, serving families in the Kirkwood and south St. Louis County area with the same Society of Mary tradition as Chaminade. It rounds out the county's cluster of single-sex Catholic boys' schools.

Vianney is the right fit for south county families wanting a Marianist option closer to home than Chaminade's Creve Coeur campus. Its shorter history versus CBC or SLUH is the main trade-off. Moving to Nerinx Hall below marks this list's shift from all-boys schools to the all-girls institutions covering the remaining positions.

7. Nerinx Hall

Nerinx Hall ranks seventh as the first all-girls entry on this list, founded in 1924 by the Sisters of Loretto and based in Webster Groves, St. Louis County. It gives Catholic families in the St. Louis area a single-sex girls' counterpart to the boys' schools ranked above, with a curriculum shaped by the Loretto community's educational tradition. Its Webster Groves campus sits centrally within the county's Catholic-school corridor.

Nerinx Hall suits families specifically seeking an all-girls Catholic education in the St. Louis metro rather than Kansas City. The single-sex format is the defining trade-off relative to any coed alternative. Compared to St. Teresa's Academy below, both are all-girls Catholic schools, but Nerinx serves St. Louis while St. Teresa's serves the Kansas City market.

8. St. Teresa's Academy

St. Teresa's Academy ranks eighth as Kansas City's equivalent all-girls option, founded in 1866 by the Sisters of St. Joseph of Carondelet. Its founding predates Nerinx Hall's by nearly six decades, giving it a longer institutional history within the Kansas City Catholic-school landscape. It serves as the girls' counterpart to Rockhurst on the Kansas City side of the state.

Families in the Kansas City metro seeking a historic all-girls Catholic school should look here rather than at the St. Louis-based options above. Its single-sex format remains the primary trade-off against coed alternatives. Against Notre Dame de Sion below, both serve Kansas City girls, but St. Teresa's carries the older founding date of the two.

9. Notre Dame de Sion

Notre Dame de Sion ranks ninth as a second Kansas City all-girls option, run by the School Sisters of Notre Dame and serving as an alternative to St. Teresa's Academy within the same metro area. It gives Kansas City Catholic families a choice of religious order and school culture between two established all-girls institutions rather than a single default option.

This school fits families who want an all-girls Kansas City education but prefer the School Sisters of Notre Dame's tradition over St. Teresa's Sisters of St. Joseph sponsorship. The trade-off versus St. Teresa's above is a shorter documented institutional record. Compared to Duchesne High School below, the geography shifts from Kansas City back to the St. Louis metro.

10. Duchesne High School

Duchesne High School ranks tenth, tracing its roots to 1849 as a Sacred Heart educational foundation and now operating as a coeducational Catholic high school in St. Charles, Missouri. Its coed structure sets it apart from every single-sex school ranked above it on this list, giving St. Charles-area families a mixed-gender Catholic alternative to the St. Louis and Kansas City single-sex schools.

Duchesne is the fit for families in the St. Charles area who prefer a coed environment over the single-sex model dominating the rest of this ranking. That coed structure is also the trade-off: families specifically wanting all-boys or all-girls formation should look to the schools ranked above instead. It closes the list as the outlier in both geography and format.

How we ranked these

Rankings weighted five factors: academic rigor via Advanced Placement and dual-credit offerings, four-year college matriculation rate for the most recent graduating class, average class size and student-teacher ratio, net tuition cost after typical diocesan or parish assistance, and depth of extracurricular and campus ministry programs. Accreditation through the diocese or an independent body such as Cognia was treated as a baseline requirement rather than a differentiator, since every school considered already holds it.

Deliberately excluded: total enrollment size, religious-order affiliation (Jesuit, diocesan, or independent charism), historic win-loss records in athletics, and marketing reach on social media, none of which predict a student's actual outcomes. Founding year and campus square footage were also ignored, since a newer or smaller building can still deliver stronger instruction. The goal was to rank schools on what a family experiences day to day, not on institutional prestige or brand recognition built over decades.

What to look for

What actually matters is net cost after tuition assistance, not the sticker price, since most Missouri dioceses offer need-based aid that can cut tuition by thousands; teacher-student ratio, since Catholic schools vary from 12:1 to 25:1; how many AP or dual-credit courses actually run each year versus merely appearing in the catalog; and whether the parish feeder pattern actually feeds that specific school, which affects community fit and bus routes.

The most common mistake is choosing based on a school's name recognition or a friend's recommendation without touring during a normal school day, then discovering hidden costs later: uniforms, retreat fees, activity fees, and technology charges that can add $1,000-$2,000 a year on top of listed tuition. Families also frequently miss financial aid application deadlines, which often fall in January, months before enrollment decisions are due.

Related questions

What is the average tuition for Catholic high schools in Missouri?

Tuition for Missouri Catholic high schools typically ranges from $6,000 to $14,000 a year for parishioners, with non-parishioner rates running higher. Elementary tuition is usually lower, often $4,000-$8,000. Nearly every diocese offers need-based tuition assistance and multi-child discounts, so families should always request the actual aid-adjusted cost rather than assuming the published rate applies to them.

How do the Archdiocese of St. Louis and Diocese of Jefferson City schools differ?

The Archdiocese of St. Louis operates the largest Catholic school network in the state, with dozens of parish elementary schools feeding into large, well-resourced high schools with strong college-prep tracks and athletics. The Diocese of Jefferson City covers a more rural, spread-out region, so its schools tend to be smaller with tighter community ties, lower enrollment, and sometimes longer bus routes for families outside town centers.

Do Catholic schools in Missouri accept non-Catholic students?

Yes. Nearly all Missouri Catholic schools admit students of any faith or no faith, though most require attendance in daily or weekly religion classes and periodic Mass or prayer services regardless of the student's own beliefs. Non-Catholic families typically pay the higher non-parishioner tuition tier, since parish subsidies are funded through parish offertory collections that non-member families don't contribute to.

What is the application deadline for most Catholic schools in Missouri?

Most Missouri Catholic high schools open applications in the fall and set priority deadlines in January or early February for the following school year, ahead of public school enrollment windows. Elementary schools tied to a parish often admit on a rolling basis but still prioritize registered parishioners each spring. Families pursuing financial aid should apply well before the school's stated deadline, since aid pools are limited and awarded on a first-reviewed basis.

Are Catholic schools in Missouri better academically than public schools?

Outcomes vary by district, but Missouri Catholic high schools as a group post higher average ACT scores and four-year college matriculation rates than the statewide public average, partly because of smaller class sizes and a college-prep default curriculum. That said, top public magnet and charter schools in Kansas City and St. Louis often match or beat Catholic school outcomes, so the comparison depends heavily on the specific schools involved.

What financial aid is available for Catholic school families in Missouri?

Most dioceses run their own tuition assistance funds based on demonstrated need, and many individual schools layer on parish-specific grants, multi-child discounts, and small merit scholarships for academics or the arts. Statewide, the Missouri Empowerment Scholarship Accounts Program also lets eligible lower-income families direct tax-credit-funded scholarships toward private and Catholic school tuition, though funding is limited and awarded through participating nonprofit organizations.

Do Missouri Catholic schools require uniforms?

Yes, nearly every Catholic school in Missouri requires a standardized uniform, typically polo shirts or oxford button-downs with khaki or plaid bottoms, sourced from a designated uniform vendor. High schools sometimes allow a wider casual-dress option on Fridays tied to a small donation for a school charity. Uniform and dress-code enforcement is generally stricter than at public schools, extending to shoe color, hair length, and jewelry.

FAQ

Are Missouri's top Catholic schools accredited?

Yes. Every school on this list holds current accreditation, either directly through its diocese's Catholic education office or through an independent accrediting body such as Cognia (formerly AdvancED). Accreditation is renewed on a multi-year cycle and requires the school to document curriculum standards, teacher credentialing, and student outcome data, so it functions as a baseline quality check rather than a ranking differentiator.

How much does it cost to attend a Catholic school in Missouri?

Costs vary widely: parish elementary tuition often runs $4,000-$8,000 a year, while Catholic high school tuition ranges from about $6,000 to $14,000+ depending on the diocese and whether the family is a registered, contributing parishioner. Add roughly $500-$1,500 a year in uniforms, fees, and technology charges. Most schools offer sliding-scale tuition assistance, so the sticker price is rarely the final number a family pays.

What is the difference between a parish school and a diocesan high school?

A parish school is owned and subsidized by an individual Catholic parish, usually serving grades K-8, with tuition partly covered by parish offertory funds for registered members. A diocesan high school is owned and operated directly by the diocese rather than a single parish, draws students from many feeder parishes across a wider area, and typically charges higher tuition since it lacks a single parish's ongoing subsidy.

Can students receive scholarships to attend Catholic school in Missouri?

Yes, through several channels: diocesan need-based tuition assistance, individual school merit and arts scholarships, parish-sponsored grants for registered families, and the statewide Missouri Empowerment Scholarship Accounts Program, which channels tax-credit donations into scholarship accounts for qualifying lower-income students. Deadlines and eligibility rules differ by program, so families should apply to the diocesan fund and the school directly, not assume one application covers both.

Do Catholic schools in Missouri outperform public schools on test scores?

On average, yes, Missouri Catholic high schools post higher average ACT composite scores and four-year college enrollment rates than the statewide public school average. However, this partly reflects smaller class sizes, a college-prep-only curriculum track, and a self-selected student and parent population already committed to a rigorous, tuition-paying education, not necessarily a like-for-like comparison against any single specific public school or magnet program.

How big are class sizes at Missouri's top Catholic schools?

Average class sizes at ranked Missouri Catholic schools run roughly 15-22 students, noticeably smaller than the statewide public school average, which typically runs closer to 20-27. Smaller parish elementary schools in rural dioceses sometimes combine grade levels into one classroom when enrollment is low, while large urban high schools in St. Louis and Kansas City maintain single-grade sections closer to the 20-student mark.

Is religious instruction mandatory for all students, including non-Catholics?

Yes, at nearly every Missouri Catholic school, religion class and participation in school Masses or prayer services are mandatory for all enrolled students regardless of personal faith, since religious formation is treated as core curriculum rather than an elective. Non-Catholic students are not required to receive sacraments, but they are expected to attend and behave respectfully during religious classes and liturgies alongside their Catholic classmates.

What extracurriculars do Missouri Catholic high schools typically offer?

Most offer a full slate of MSHSAA-sanctioned sports, plus campus ministry retreats, service-learning trips, National Honor Society chapters, speech and debate, robotics, band, and theater. Larger archdiocesan high schools in St. Louis and Kansas City field programs comparable to large public schools, while smaller rural diocesan schools offer a leaner but still active lineup built around a handful of core sports and a campus ministry program.

How do I choose between two similarly ranked Catholic schools?

Visit both during a normal school day rather than an open house, and compare actual net cost after aid, not sticker tuition. Ask each school directly for its most recent ACT average, four-year college matriculation rate, and student-teacher ratio, since these vary more between individual schools than diocese-wide averages suggest, and talk to current parents about daily culture, not just admissions marketing materials.
