Mission Statement

Saint Agnes School was established in 1888 and is rich in history and tradition. For over 125 years, we have committed to teaching the Gospel message of Christ; to building a community of faculty, staff and students that is characterized by sharing, educating and believing; and to serving through prayer, worship and social action.

Arlington Catholic High School was founded in 1960 under the direction of Monsignor Oscar O’Gorman.  It was built by the parishioners of Saint Agnes Parish in Arlington, and originally staffed by the congregation of the Sisters of Saint Joseph.  Since its inaugural class of 1964, Arlington Catholic has graduated over 9,000 students. Our alumni share the common experience of excellent preparation for study beyond high school and for making a difference in the world.  This tradition remains strong today.

In 2017, Saint Agnes School and Arlington Catholic High School joined forces to take two strong schools and make one stronger school with a coordinated, unified program for students in Pre-K through Grade 12.

There are currently over 800 students at the school, coming from more than 47 cities and towns near Arlington representing more than 50 parishes in the archdiocese, as well as 8 countries. 100% of students who apply to post-secondary programs are accepted and pursue higher education at prestigious Catholic and Ivy League colleges including Boston College, Columbia University, Fordham University, Providence College, St. John’s University, Salve Regina University, University of Notre Dame, and Case Western Reserve University.

“Saint Agnes School and Arlington Catholic made me who I am. In addition to a great education, I was given a community. This sense of belonging allowed me to grow emotionally, spiritually, and socially. Saint Agnes School gave me a solid foundation, and Arlington Catholic High School gave me wings.”
