Summary:
Zip code 20147 in Ashburn, VA is served by two public middle schools, Trailside Middle and Farmwell Station Middle, both covering grades 6–8 within the highly rated Loudoun County Public Schools district.
Trailside Middle is the standout school in this area. It earned 5 stars for both the 2024–2025 and 2025–2026 school years, ranking 22nd and 33rd respectively among more than 400 Virginia middle schools. In 2025–2026, Trailside posted higher proficiency than Farmwell Station in most subjects, with 85.2% average proficiency versus 81.6%, and had a lower chronic absenteeism rate (11.4% vs. 15.1%). Trailside also serves a lower percentage of students from low-income households (21.7% free/reduced lunch vs. 32.4% at Farmwell). Farmwell Station remains a solid choice, earning 4 stars and sitting in the 80th percentile statewide, but it has trended downward in rank over three years, from 44th in 2023–2024 to 82nd in 2025–2026, while Trailside climbed from 96th to 33rd over the same period.
Both schools excel in advanced math—7th-grade Algebra I proficiency was 100% at both schools in 2025–2026, and 8th-grade Geometry was 100% at Trailside and 98.6% at Farmwell. Regular grade-level math is the relative weak spot, with Trailside’s 7th-grade math dropping from 82.7% to 55.7% year-over-year and Farmwell’s 8th-grade math falling from 71.7% to 59.0%. Despite spending about $800 more per student, Farmwell earns lower scores and has higher absenteeism, likely reflecting its higher share of economically disadvantaged students. Still, both schools outperform state averages in nearly every subject, and even the lower-ranked Farmwell Station sits in the top 20% of middle schools statewide—making this zip code a strong option for families seeking high-quality public middle schools.
