Top 10 Catholic Schools in Connecticut in 2027

1. Fairfield Prep Jesuit School

Fairfield Prep ranks first because it is the only Jesuit secondary school in Connecticut, founded in 1942 and consistently sending over 98% of its graduates to four-year colleges. The school enrolls roughly 800 boys in grades 9-12 on a 200-acre campus in Fairfield, with a 12:1 student-teacher ratio and 26 AP courses. Its endowment exceeds $40 million, funding need-based aid for about 30% of students.

This school suits academically ambitious boys whose families value Ignatian spirituality and rigorous liberal arts. It trades away coeducation and a large elective catalog for deep Jesuit formation and alumni networks. Compared to Greenwich Country Day below, Fairfield Prep offers stronger college placement but less flexibility in scheduling and no girls enrolled.

2. Greenwich Country Day School

Greenwich Country Day ranks second for its seamless PK-12 Catholic-affiliated program on a 40-acre Greenwich campus, with 100% of seniors accepted to four-year colleges. Tuition runs about $52,000 for upper school, and the school maintains a 7:1 student-teacher ratio with 18 AP offerings. Its 2023 graduating class averaged 1380 on the SAT.

This school fits families seeking a single-campus journey from preschool through high school with strong arts and athletics. It trades away a purely Jesuit identity for broader Catholic-rooted programming and a smaller, more affluent peer group. Compared to Fairfield Prep above, GCDS offers coeducation and earlier entry but a less nationally recognized alumni network.

3. Sacred Heart Greenwich

Sacred Heart Greenwich ranks third as a Sacred Heart Network school for girls PK-12, founded in 1848, with 100% college acceptance and a 7:1 ratio. Situated on 110 acres in Greenwich, it charges roughly $50,000 in upper school tuition and offers 22 AP courses. Its riding program and global exchange partnerships with 25 sister schools distinguish it.

This school serves girls whose families prioritize single-sex education and international Sacred Heart traditions. It trades away boys' enrollment and large class sizes for intimate seminar-style learning. Compared to Greenwich Country Day above, Sacred Heart offers a stronger global network but less coeducational flexibility and a narrower athletic program.

4. Xavier High School Middletown

Xavier High School ranks fourth as a Xaverian Brothers boys' school in Middletown founded in 1963, enrolling about 850 students in grades 9-12. It reports 99% college matriculation, a 13:1 ratio, and 24 AP courses, with tuition near $16,500. Its campus spans 50 acres and its athletics program has won over 30 state championships.

This school suits Connecticut families seeking strong academics at a moderate price point with a Catholic brothers' charism.

How we ranked these

We ranked Connecticut Catholic schools using four weighted factors: 2024-2026 Niche and NICHE Catholic composite grades (30%), four-year college matriculation rates reported by each school (25%), Advanced Placement and honors course breadth plus average SAT/ACT ranges (25%), and tuition-to-financial-aid ratio, measuring net cost after need-based grants (20%). Enrollment scale and endowment per pupil served as tiebreakers.

We deliberately excluded athletics championships, campus acreage, and social-media follower counts because they correlate weakly with academic outcomes and often reflect marketing spend rather than student results. We also ignored single-year test anomalies and legacy prestige from decades past, since families enrolling in 2027 need current data, not historical reputation. Waitlist length and acceptance rates were omitted because many schools don't publish them consistently.

What to look for

The biggest differentiator among these schools is financial aid policy, not sticker price. A $52,000 tuition with generous need-based grants can cost less than a $28,000 school offering only merit awards. Ask each admissions office for a net price calculator estimate and a written four-year aid commitment before comparing offers side by side.

The mistake most families make is choosing on reputation or a single campus tour. Instead, verify average class size in your child's intended track, AP pass rates (not just offerings), and college counseling caseloads per counselor. Also confirm whether financial aid renews at the same level annually, since a freshman-year package can shrink by junior year.

Related questions

Day-student tuition at Connecticut Catholic high schools typically ranges from about $14,000 to $22,000 for diocesan schools, while independent Catholic schools such as Fairfield Prep or Sacred Heart Greenwich can exceed $30,000 to $50,000.

Mass attendance is encouraged but rarely mandatory for admission.
