Summary
Oakton High is a large suburban high school in Vienna, Virginia, serving 2,621 students in grades 9–12 as part of Fairfax County Public Schools. The school is consistently among Virginia's best, ranking 41st out of 331 high schools (88th percentile, 4 stars) in 2025–2026, and it has spent most of the last five years firmly in the top 10–15% of the state.
Oakton's academic results are exceptionally strong across the board. Eleventh-grade reading proficiency was 96.93% in 2025–2026, compared with 88.13% statewide. Ninth-grade geometry proficiency reached 96.55% versus 85.88% statewide, and 11th-grade chemistry proficiency was 80% against a statewide average of just 37.62%. The school also produces strong outcomes for a wide range of student populations, including military-connected students, English-language learners, students with disabilities, and low-income students. With a free/reduced-price lunch rate of just 15.3%, Oakton serves a relatively affluent community, and it does so efficiently—spending $9,680 per student, the lowest among all neighboring high schools in the data.
The main areas to watch are attendance and recent momentum. Oakton's chronic absenteeism rate was 16.4% in 2024–2025, well above the district average of 11.9% and notably higher than Madison High (9.6%), Woodson High (12.0%), and Robinson Secondary (12.7%). While Oakton's 96.8% graduation rate is strong, it trails close neighbors like Lake Braddock Secondary (98.5%), Robinson Secondary (98.4%), Madison High (98.3%), and Woodson High (98.1%). In the most recent state ranking, Meridian High, Madison High, and Woodson High placed ahead of Oakton, though Oakton remains ahead of Lake Braddock Secondary and several other area schools. One data point worth monitoring is 10th-grade Algebra II proficiency, which dropped to 68.75% in 2025–2026, well below the district's 86.1%—a break from Oakton's otherwise consistent math performance.
