Summary:
Zip code 20109 in Manassas, Virginia is home to one middle school, Unity Braxton Middle, which serves grades 6–8 as part of Prince William County Public Schools.
Unity Braxton Middle shows clear strengths in advanced coursework, with 100 percent proficiency in 8th grade Geometry and 7th grade Algebra I, and 96.15 percent in 8th grade Algebra I. Civics is another bright spot, with 81.82 percent proficiency that nearly matches the district and exceeds the state average by about 7 percentage points. However, grade-level math and reading proficiency lag far behind district and state averages. Grade-level math proficiency ranges from just 26 to 37 percent, while reading proficiency falls between 49 and 57 percent, leaving gaps of up to 24 percentage points compared to the state. These struggles have contributed to a declining statewide rank, dropping from the 16th percentile in 2023–2024 to the 11th percentile in 2025–2026.
The school serves 1,055 students, with 69.19 percent eligible for free or reduced lunch, reflecting a predominantly economically disadvantaged population. Chronic absenteeism stands at 13.8 percent, matching the district average and sitting slightly below the state average. With a student-to-teacher ratio of 13.2:1 and per-student spending of $12,473, resources appear reasonable. The steep year-over-year decline in math proficiency, including a 15.83-point drop in 7th grade math and a 14.53-point drop in 8th grade math, underscores an urgent need for targeted instructional support in core subjects, especially for students not currently enrolled in the advanced math track.
