Welcome to Immaculate Heart of Mary School
IHM is an apostolate of Saint Benedict Center in Harvard, MA.
We have been providing a Traditional Catholic Education to students in Grades 1–12 since 1976… and we are growing!
To Jesus through Mary
Immaculate Heart of Mary School is a private Catholic school dedicated to the Mother of God and taking its name and spirit from the writings of Saint Louis Marie de Montfort’s “True Devotion to Mary.” All subjects are taught in the light of the Faith, striving to form the whole person as a Child of God destined for Eternal Life.
The Sisters MICM (Slaves of the Immaculate Heart of Mary) teach Grades 1–8 at the Elementary building and the Brothers MICM instruct Grades 9–12 at MacIsaac Hall across the road.
Living Tradition
IHM students are blessed to attend the Latin Mass daily and to enjoy the full benefits of Traditional Catholicism by frequenting the sacraments.
Dedicated to Mary
We promote Total Consecration to Jesus through Mary among the students. As one priest friend once said of IHM, “Our Lady walks these halls.”
Academically Excellent
Quality Catholic education encourages discipline and high standards that form the soul, mind and body to achieve success in time and eternity.
Thankful for the
IHM School Expansion!
The IHM School Expansion project is now a reality—fully in use and truly beautiful! The 2025–2026 academic year marked a milestone as the new space fulfilled its intended purpose. We are deeply grateful to everyone who contributed to this project. Each effort has been vital to bringing this vision to life.
Forming the
