Summary

Rocky Run Middle is a grades 7–8 middle school in Chantilly, VA, serving 882 students as part of Fairfax County Public Schools, and it stands as one of Virginia's elite middle schools, ranked 21st out of 416 schools statewide (95th percentile) for 2025–2026. The school has earned a 5-star rating for ten straight years and has ranked between 9th and 21st in the state over the past five years. This consistency separates it from nearby schools — Carson Middle (52nd), Franklin Middle (79th), and Liberty Middle (142nd) — and even the closest competitor, J. Michael Lunsford Middle in Loudoun County, trails at 43rd.

Academically, Rocky Run posts exceptional SOL proficiency rates. Reading scores reach 93% in 7th grade and 92.6% in 8th grade, about 10–12 points above the nearest neighbors. Advanced math is a standout: Algebra I, Geometry, and Algebra II proficiency run 99–100%, well above district and state averages. Even 7th-grade grade-level math proficiency (74.5%) dwarfs the district's 47.8% — and Herndon Middle's 13.3%. Science proficiency is 87.3%, versus 74.2% for the district. Chronic absenteeism is the lowest in the area at 9.0% compared with 11.8–15.6% at neighboring schools, signaling strong student engagement.

What makes Rocky Run rare is its success across every student group. It ranks 1st in Virginia for multi-racial and military-connected students, 4th for African American students, and in the 88th–95th percentile for English Language Learners, students with disabilities, low-income students, and both genders. Hispanic students climbed from the 73rd to the 90th percentile in just two years. The school achieves all this with efficient spending — $11,983 per student and a 15.1 student-teacher ratio — compared with Herndon Middle's $15,367 per student and 9.9 ratio. The one area to watch is 8th-grade grade-level math at 49.4%, near the state average, likely because many top students take Algebra I or Geometry instead. Overall, Rocky Run is a benchmark for academic excellence and equity in Northern Virginia.

This place is the best! it has great teachers and students to befriend. There is zero bullying. I only started this year and I love it! There are also clubs afterschool and don't worry about pick up, there are late buses. This school is amazing! Close Quote
