Kevin’s tipVisit before you decide, public or private. Read the state report card first, so the tour can answer what the data cannot.
Fairfax County groups its schools into high school pyramids, each one a high school with the middle and elementary schools that feed it. Four of them cover the Fairfax County places in this guide: the South Lakes pyramid, built on South Lakes High School in Reston; the Herndon pyramid, on Herndon High School in Herndon; and the McLean and Langley pyramids, on McLean High School and Langley High School, both in McLean (fcps.edu/resources/maps). Pyramid lines run street by street, so the county’s boundary locator, not the town name, is what settles an address (boundary.fcps.edu). Loudoun County assigns by attendance zone rather than by pyramid; its Attendance Boundary E-Listing returns the schools for any address (lcpsplanning.com/loudounlabel). The City of Fairfax owns its four school buildings and Fairfax County Public Schools operates them under a School Services Agreement first signed in 1962 (cityoffairfaxschools.org). In the District, DC Public Schools assigns a neighborhood school by address, and out-of-boundary DCPS seats and public charter seats are filled through one common lottery, My School DC (myschooldc.org). Virginia enrollment is fall membership counted September 30, 2025 and published on the Virginia Department of Education’s School Quality Profiles (schoolquality.virginia.gov), the most recent year posted there; Maryland’s is the Montgomery County Public Schools official enrollment report run November 11, 2025 for the September 30, 2025 count; the District’s is the OSSE 2025-26 enrollment audit (osse.dc.gov/enrollment).
