Summary:
Zip code 20148 in Ashburn, Virginia, is home to 8 public elementary schools serving grades PK–5, all part of Loudoun County Public Schools. This is a high-performing, relatively affluent cluster: the 6,180 students collectively exceed both district and state averages in every SOL subject. Average math proficiency is 89.7% versus 73.2% statewide, reading is 87.5% versus 71.2%, and science is 83.5% versus 68.8%. Free/reduced lunch eligibility ranges from 10.5% to 23.9%, and chronic absenteeism averages 11.9%, below the district's 14.1%.
Four schools are elite by any measure. Mill Run Elementary is the clear standout, ranked #10 in Virginia with top scores in math (96.1%), reading (93.2%), and science (93.2%). Madison's Trust Elementary is nearly as strong at #31, and it achieves this while serving the largest enrollment (1,004 students) with the lowest per-pupil spending in the group. Waxpool Elementary (#38) and Legacy Elementary (#56) round out the top tier. At the other end, Moorefield Station Elementary ranks #327 with the zip's lowest math and reading scores and highest free/reduced lunch rate (23.9%), while Creighton's Corner Elementary ranks #227 and leads the area in chronic absenteeism at 18.1%.
Three insights stand out. First, attendance matters: the four schools with chronic absenteeism below 10% include three of the top four ranked schools, while the two most-absent schools rank lowest. Second, spending does not drive results — Madison's Trust spends the least per student yet outperforms most peers. Third, 5th-grade science is the most volatile subject: Hillside Elementary dropped 12.7 points and Moorefield Station dropped 11.6 points from 2024–25 to 2025–26, even as Madison's Trust improved. VA Studies is a notable strength across all eight schools, averaging 91.9% proficiency.
