St. Mary of the Assumption School

What St. Mary of the Assumption School does

St. Mary of the Assumption School is a private Catholic school located at 67 Harvard Street in Brookline Village, Massachusetts, founded in 1899 as a parish elementary school. The institution currently operates as a single-campus, non-profit educational provider serving children from infancy (3 months) through Grade 8, and is positioned as Brookline's only Catholic school spanning this full age range. The school delivers an integrated Catholic education program combining religious instruction (via the Sadlier Religious Curriculum and an S.T.A.R.S. values framework) with Common Core State Standards- and Massachusetts Frameworks-aligned academics, including English language arts, mathematics, science, social studies, technology, world languages (Spanish and French from Grade 6), and STEM/Robotics in middle school. Student support services include a Dean of Students, School Guidance Counselor, Student Support Specialist/Literacy Coach, and School Nurse. The faculty comprises 11-50 full-time lay teachers, learning support specialists, classroom aides, and instructors in art, music, and physical education, delivering instruction at a stated 15:1 student-teacher ratio.

The school's revenue model is built on four streams: recurring tuition (Infant care at $700/week, Toddler at $630/week, PreK-K1 at $14,430/year, and K2-8 at $10,310/year); an Annual Fund (The Fund for St. Mary's) supported by donations, Casino Night events, and an Annual 5K race; Extended Day Program fees ranging from $22 to $55 per day depending on pickup time; and need-based financial aid subsidized through partnerships with the Catholic Schools Foundation and St. Vincent De Paul Society. Go-to-market is admissions-led, relying on a website, Principal's Weekly newsletter, in-person Discovery Days, Touring Tuesdays, Online Info Sessions, and a Director of Admissions who personally guides prospective families through the RenWeb online application portal. Tuition is processed through the mandatory FACTS Tuition Management Plan with single, two-payment, or up-to-10-months installment options, with a 1.5% monthly (18% annual) late-payment interest charge. Back-office technology consists of the FACTS Family Portal/RenWeb platform for family management, communication, and tuition processing, plus PSB Food Services (Brookline Public Schools) for hot lunch.

Governance is provided by a Board of Specified Jurisdiction established in 2019 in partnership with the Healey Education Foundation, with voting oversight of enrollment, fundraising, and fiscal management. The current principal, Dr. Christine Nadjarian, was appointed in 2021 and led the school to its 2024 National Blue Ribbon School designation (one of 356 nationwide, 9 from Massachusetts). The student body represents over 25 languages and 25 communities, and 100% of 8th graders are placed at area high schools including Boston College High School, Brookline High School, Boston Latin School, Boston Latin Academy, Catholic Memorial, Fontbonne Academy, Newton Country Day, Malden Catholic, Miss Hall's, and Xaverian Brothers. The school is NEASC-accredited and has received Boston Parent Family Favorite recognitions (Preschool, Elementary, and Middle School) in 2023-2025.
