Schools in Zip Code 20155

ZIP code 20155 in Gainesville, Virginia, is served by six public schools — three elementary schools, two middle schools, and one high school — all part of Prince William County Public Schools. Combined enrollment is about 6,959 students, ranging from roughly 490 at George G. Tyler Elementary to 2,648 at Gainesville High.

This is a strong school area with no weak options. Glenkirk Elementary is the clear academic leader, ranking in the 98th percentile statewide with all test scores above 89%. Gainesville Middle is the top middle school at the 90th percentile, with 100% proficiency in 8th grade Geometry and Algebra I, plus strong reading, science, and civics results. Gainesville High stands out for its 98.1% graduation rate and 0.7% dropout rate, both far better than district and state averages. Buckland Mills Elementary is also solid at the 86th percentile, and even George G. Tyler Elementary — despite having the highest poverty rate in the ZIP code — beats Virginia state averages in every tested subject.

The main challenges are socioeconomic disparity and modest on-grade-level middle school math. Free/reduced lunch rates range from 18% at Glenkirk to 70% at George Tyler, which closely tracks academic rankings. Advanced math scores are exceptional (93–100% in Geometry and Algebra I), but regular 7th and 8th grade math proficiency sits around 55–57%, still above state averages. Chronic absenteeism is low across every school, well below district and state rates. Several schools are improving, including Buckland Mills (76th to 86th percentile), Bull Run Middle (65th to 70th), and Gainesville High (74th to 78th). Notably, spending per student does not clearly predict performance — Gainesville Middle spends less than Bull Run Middle but ranks significantly higher. The bottom line: every school in 20155 outperforms its already above-average district, making this ZIP code a consistently strong choice for families.
