Arlington Catholic High School was founded in 1960 under the direction of Monsignor Oscar O’Gorman. It was built by the parishioners of St. Agnes Parish in Arlington and originally staffed by the congregation of the Sisters of St. 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 have joined forces to take two strong schools and make one stronger school with a continuous, 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.
