Summary:
Zip code 20124 (Clifton, VA) contains just one middle school, Liberty Middle, which serves grades 7–8 with an enrollment of 913 students within Fairfax County Public Schools. Liberty Middle is a school of contrasts: it delivers near-perfect results in accelerated math courses while grade-level math proficiency remains a notable weak point, particularly in 7th grade. The school sits in the 66th percentile of Virginia middle schools with a 3-star rating, while its district is ranked in the 70th percentile with a 4-star rating, making Liberty a solid but not top-tier school within a highly regarded system.
In advanced mathematics, Liberty Middle is exceptional. Students score 100% proficiency on the 8th-grade Geometry SOL and 7th-grade Algebra I SOL, with 97.61% on 8th-grade Algebra I—all at or above the state's top performance. However, only 47.14% of 7th graders and 52.38% of 8th graders are proficient in on-grade-level Mathematics SOLs. The 8th-grade math score is well above the district average of 33.05%, but the 7th-grade score lags slightly behind the state. Reading performance is consistent and above state averages (78.16% in 7th and 77.85% in 8th) but below Fairfax County averages. Science proficiency (71.66%) similarly exceeds the state but trails the district.
The most striking change is the year-over-year drop in 7th-grade math proficiency, from 65.65% in 2024–2025 to 47.14% in 2025–2026—a decline of more than 18 points that warrants investigation. Chronic absenteeism is 14.1%, above the district's 11.9% but below the state's 14.8%. With a student-teacher ratio of 11.6, a free/reduced lunch rate of 37.79%, and per-student spending of $14,282, Liberty offers favorable class sizes and substantial resources. Overall, Liberty Middle is an above-average school within a top Virginia district, with advanced coursework as its clear strength and grade-level math as the area most deserving of attention.
