As Trinity High School and Saint Joseph Junior High School, ranked the #1 private junior high school and private high school in NH for the past two years, enjoy their second academic year on a newly renovated and expanded shared campus, the spirit of innovation, community, and faith is more vibrant than ever. Nestled in the heart of Manchester, NH, these two dynamic and innovative Catholic schools have come together to form one thriving educational family—offering students in grades 7 through 12 an inclusive, future-forward, and faith-filled learning environment that serves over 40 towns and cities throughout New Hampshire and Massachusetts. 

The campus expansion has transformed the schools' physical and academic landscape. Students now enjoy access to state-of-the-art media equipment and robotics lab, a beautiful and peaceful new chapel, a gorgeous new fine arts wing, a brand new fitness center, a renovated gymnasium, and an expanded Academic Support Center designed to meet the diverse needs of today’s learners. This new space not only enhances the student experience but also fosters a deeper sense of unity between the junior high and high school communities, while maintaining their unique histories, identities, and traditions. 

Though they serve distinct age groups, Trinity High School and Saint Joseph Junior High School share a common vision: to provide a co-educational, inclusive Catholic education that nurtures academic excellence, personal growth, and spiritual development.

Saint Joseph Junior High School offers a traditional yet robust junior high experience for students in grades 7 and 8. With a rigorous curriculum that emphasizes study skills, critical thinking, and personal responsibility, St. Joe’s sets a strong foundation for academic success. Students benefit from a supportive environment that balances academic challenge with personal guidance. Beyond the classroom, St. Joe’s students can get involved in more than 14 athletic teams and a wide range of student organizations, fostering well-rounded development during these formative years.

At Trinity High School, the commitment to excellence continues with a challenging curriculum that ensures every graduate earns NH Scholar status. Trinity’s academic program includes 13 dual enrollment and early college credit courses, as well as 10 Advanced Placement (AP) courses, giving students a competitive edge as they prepare for higher education.

The Class of 2025 alone earned a remarkable $17.3 million in academic scholarships, with 90% of graduates attending four-year colleges or universities, 8% heading to two-year colleges, and 2% pursuing a post-graduate year. These outcomes reflect Trinity’s holistic approach to college and career readiness. Students have access to career and trade exploration pathways, on-the-spot admissions days, merit articulation agreements, an annual college and career fair, and even religious vocation exploration—ensuring that every student can find a meaningful next step after graduation.

Both St. Joe’s and Trinity emphasize the importance of student engagement beyond the classroom. With more than 40 varsity sports teams and student-led organizations across the combined campus, students are encouraged to explore their interests, develop leadership skills, and form lasting friendships. From robotics and campus ministry to student government and performing arts, there’s truly something for everyone.

Over the past year, both schools have experienced a significant enrollment growth of 11% — so much so that they entered into a waitlist for the 2025–2026 academic year. This surge in interest reflects a growing recognition of the schools’ commitment to academic excellence, faith-based values, and personalized student support.

Each school's Student Success Model ensures that every student has access to the resources they need to thrive. With tailored support pathways and an emphasis on personal responsibility, students are empowered to reach their fullest potential—academically, socially, and spiritually.
