About Us

Just a half-mile from Harvard Square in Cambridge, Massachusetts, Saint Peter is a Catholic elementary school where every child is nurtured—heart, mind, and soul. We offer a rigorous, values-based academic program for a diverse community of students from Pre-K through Grade 8. Rooted in faith and focused on excellence, we help each child grow, learn, and thrive in our joyful learning environment.

Our Mission

The mission statement of Saint Peter School - “to teach to the mind, heart, and soul of each student” - embodies our holistic approach to education that seeks to nurture the whole person, not just academically, but spiritually, emotionally, and socially as well. We recognize that each child is more than a mind to be filled with facts; they are individuals with unique hearts and souls that need care, guidance, and support. A Saint Peter education  prepares students not just for success in school, but for lives of purpose, service, and leadership.

Our Vision
