Summary

Mill Run Elementary is a PK-5 public elementary school in Ashburn, VA, serving 636 students within Loudoun County Public Schools. The school holds a 5-star rating and ranks #10 out of 1,111 Virginia elementary schools (99th percentile) for 2025–2026 — the highest ranking among nearby Ashburn elementary schools. With a student-teacher ratio of 13.4:1 and a chronic absenteeism rate of 7.3% (about half the district average of 14.1%), Mill Run demonstrates strong operational health. Only 10.5% of students qualify for free/reduced lunch, and the school has maintained its 5-star rating for eight consecutive years.

Academically, Mill Run achieves 90%+ proficiency in every tested subject. Fifth-grade math proficiency is 97.4%, 3rd-grade reading is 90.9%, and 5th-grade science is 93.2%. These scores exceed district averages by 12–16 points and state averages by 20–26 points. Compared to neighboring schools, Mill Run leads in nearly every category: its science score surpasses Madison's Trust Elementary (90.4%), Waxpool Elementary (87.8%), and Legacy Elementary (85.1%), while its 3rd-grade reading score tops both Madison's Trust (84.7%) and Waxpool (87.3%). Nearby schools like Hillside Elementary (#173) and Dominion Trail Elementary (#733) rank significantly lower, showing that strong outcomes come from school-specific factors rather than location alone.

What's particularly impressive is Mill Run's consistent improvement over time. Its state ranking rose from #112 in 2015–2016 to #10 today, and students with disabilities saw their subgroup rank jump from #130 to #49 in just two years. Chronic absenteeism has also fallen sharply from a post-pandemic peak of 17.0% to 7.3%. Notably, Hispanic students rank #6 statewide and low-income students rank in the 95th percentile, demonstrating the school's success in supporting all learners. Mill Run achieves these results with per-student spending of $17,349 — mid-range compared to several lower-performing neighboring schools that spend more.
