Archbishop Carroll High School is a Catholic college-preparatory high school with an emphasis on social justice and civic engagement,[7] located in the Brookland neighborhood of Northeast Washington, D.C.

[9][10] Archbishop Carroll High School opened in 1951 and expressed the vision of Patrick A. O'Boyle, the first archbishop of the Archdiocese of Washington, who felt strongly that the Catholic Church should lead by example in the area of integration.

Named in honor of John Carroll, the first Catholic archbishop in the United States, the school offered a college preparatory education for young men, regardless of race or ethnicity.

[1] In 1989, the Archdiocese of Washington closed three of its four high schools—the all boys' Mackin, and girls' schools All Saints and Holy Spirit—leaving one, Archbishop Carroll.

[citation needed] As of the 2019-2020 School Year, Archbishop Carroll High School has transitioned to pre-Advanced Placement (PreAP) and Advanced Placement (AP) coursework.
