Best Public Schools in Zip Code 20147

Zip code 20147 in Ashburn, Virginia is served by 12 public schools within Loudoun County Public Schools — a district ranked 18th out of 131 in Virginia — encompassing 8 elementary schools (PK-5), 2 middle schools (6-8), and 2 high schools (9-12) that together enroll roughly 10,041 students. The area is high-performing overall: most schools exceed state averages in reading, math, and science, although there is meaningful variation between individual schools. Families in this zip code have strong options at every grade level, but school choice within the area can matter a great deal.

Stone Bridge High is the clear academic leader among high schools, ranking 35th of 331 in Virginia with a 99.0% graduation rate and a 0.4% dropout rate — far better than district and state averages. Trailside Middle is the only 5-star school in the zip code, ranked 33rd of 416, with perfect 100% proficiency in 8th-grade Geometry and 7th-grade Algebra I. At the elementary level, Newton-Lee Elementary ranks highest at the 80th percentile, combining strong math and reading scores with the lowest chronic absenteeism rate (10.0%) in the area. Honorable mentions include Sanders Corner Elementary for outstanding 3rd-grade math and reading, and Belmont Station Elementary for strong 5th-grade math.

However, the data reveals sizable gaps within this single zip code and district. Dominion Trail Elementary ranks in the 34th percentile with a 44.0% free/reduced lunch rate, while Broad Run High trails Stone Bridge on nearly every academic measure despite having lower chronic absenteeism. Spending does not clearly predict performance — Broad Run spends more per student than Stone Bridge, and Dominion Trail outspends several higher-ranked elementary schools. On the positive side, both middle schools excel in accelerated math, feeding strong 9th-grade Algebra II proficiency at both high schools. Science proficiency is the biggest differentiator between schools, and several elementary and middle schools have seen declining state rankings over the past three years.
