St. Mary’s School is a coeducational Catholic parish school for students in Pre-K through grade 12 located in downtown Annapolis, Maryland. Anchored in faith, rooted in tradition and committed to excellence, our programs build lifelong learners who are servant leaders.
St. Mary’s Elementary School has a broad educational curriculum, which imparts both physical and academic skills to our students. The skills afford knowledge and attitudes that enable students to continue to learn and act with self-confidence in an ever-changing world.
St. Mary’s High School continues to build on this foundation in our college preparatory program. Our students excel in and out of the classroom, on the field and in service to the community. The Class of 2022 had a 100% college acceptance rate, earning more than $13 million in scholarships.
Celebrating 160 years in our elementary school and 76 years in our high school, our rich tradition of academic excellence continues to service young minds and hearts, creating an atmosphere for the development of mind, body and spirit. Our graduates leave us well prepared to be positive contributing members of their communities.
