Summary:
Zip code 20124 contains just one high school: Centreville High in Clifton, Virginia, a large school serving 2,347 students in grades 9–12 as part of Fairfax County Public Schools. The school has a 12.8:1 student-teacher ratio, 31.15% of students eligible for free/reduced lunch, and per-student spending of $11,449. It currently holds a 3-star rating and ranks 142nd out of 331 Virginia high schools (57th percentile), a modest improvement from the 50th percentile in 2023–2024.
Academically, Centreville is a school of contrasts. Overall SOL proficiency (76.5% in 2025–2026) sits right at the district (75.8%) and state (75.3%) averages, but results vary sharply by subject. Math is a clear strength: Algebra I proficiency is 81.0% and Algebra II is 85.9%, both exceeding state averages. Biology is roughly average at 72.7%. However, Earth Science proficiency is just 41.7%—about 10 points below the district and state—and English Reading at 73.2% trails the state's 78.2%.
The biggest takeaway for parents is the grade-level gap. Ninth graders perform exceptionally well, averaging 92.6% SOL proficiency versus 86.5% statewide, with standout Algebra II (97.7%) and Biology (95.3%) results. But 10th- and 11th-grade proficiency drops to 55.3% and 61.2%, respectively—both below state averages—suggesting many upperclassmen struggle with retakes and later-year coursework. Chronic absenteeism (18.1% versus 14.8% statewide) and a dropout rate of 6.3% (versus 5.0% statewide) are additional red flags, though the graduation rate of 91.5% remains close to the state's 92.3%.
