Many thanks for taking time to explore Mercy High School, a private, Catholic college preparatory school for 440 girls in grades 9-12 sponsored by the Sisters of Mercy. Founded in 1960, Mercy is proud to carry forward the extraordinary legacy of Mercy education, which began at Mount Saint Agnes in 1867. The only all-girls Catholic school in the Archdiocese of Baltimore authorized as an International Baccalaureate World School, Mercy provides our Mercy Girls with the preparation that will help them become the Women of Mercy our world needs. Today, more than 8,000 graduates claim Mercy as their alma mater, and we are deeply proud of the generous ways they lead and serve in their professions, places of worship, communities, and families.
Shaped by the vision and values of the Sisters of Mercy and their foundress, Catherine McAuley, Mercy High School is part of a global network of 198 Mercy secondary schools. Together we share in a mission to help our students live out our Mercy values—excellence, hospitality, service, justice, and compassion—so that our students become the people God calls all of us to be. With two centuries of experience teaching girls and women, the Sisters of Mercy are experts in the education of adolescent girls. Their commitment to healthcare, expressed in Baltimore through our sister ministry, Mercy Medical Center, also informs our thoughtful, personalized approach to guiding our Mercy Girls through the joys and challenges of their formative high school years.
A sharp focus on the high school experience is a key differentiator at Mercy. With every Mercy Girl joining our community as a 9th grader, the freshman year is “a level playing field.” Every new Mercy Girl starts in the same place, building new friendships and exploring new interests. In partnership with parents, our exceptional teachers draw out the very best from our Mercy Girls. We are honored to journey with our Mercy families at this critical time in the life of a girl.
I invite you to join us for admissions events, our many fine arts offerings, athletic events, alumnae activities, and so much more! We look forward to offering you our warm Mercy hospitality, rooted in the timeless charism of the Sisters of Mercy.
