The vast majority of the school's students reside in the area of the county commonly called "North Arlington" which is the portion of the county north of Arlington Boulevard (US Route 50). The attendance area covers the high rise neighborhood of Rosslyn, which borders Georgetown, all the way to the more suburban neighborhoods of North Arlington bordering Falls Church and McLean. A small portion of McLean (22101) and a small portion of Falls Church (22046) within Arlington County are under the jurisdiction of the Arlington Public Schools and its students attend Yorktown. Many of the neighborhoods in the Yorktown attendance area are also zoned to Washington-Liberty High School. High school boundary changes between the two schools historically have occurred at least once every decade.
