Summary:
Zip code 20121 in Centreville, Virginia contains a single high school, Mountain View High, serving grades 9-12 as part of Fairfax County Public Schools. This small school of 145 students stands out dramatically from its district and state peers, but not in a positive way.
Mountain View High has a 2024-2025 graduation rate of just 42.7% versus the district's 92.7% and state's 92.3%, while its dropout rate of 51.0% is roughly ten times the district and state averages. Chronic absenteeism affects 54.2% of students, compared to 11.9% districtwide. The school spends a remarkable $40,621 per student with a 6.8:1 student-teacher ratio, yet these resources have not translated into strong overall outcomes. Its state ranking has improved slightly from the 9th to 16th percentile over three years, though it remains in the bottom fifth of Virginia high schools.
Test performance is inconsistent and highly volatile due to the small student body. In 2025-2026, 10th-grade Algebra I proficiency reached 76.19% and 12th-grade Earth Science reached 78.57%, both exceeding district and state averages. However, 9th-grade Algebra I (47.62%) and 11th-grade English Reading (61.54%) lagged far behind. The 11th-grade English Reading score swung from just 31.03% in 2024-2025 to 61.54% in 2025-2026, illustrating how a handful of students can shift percentages dramatically. With 46.9% of students eligible for free or reduced-price lunch, the school appears to serve a high-need population, and its alarming absenteeism likely drives low graduation rates and erratic academics. For parents, this is a school with isolated bright spots but severe engagement and completion challenges, possibly functioning as an alternative or credit-recovery program within an otherwise high-performing district.
