Summary:
Zip code 20170 in Herndon, Virginia contains just one middle school: Herndon Middle, which serves grades 7 and 8 and enrolls 895 students. Part of Fairfax County Public Schools, the school operates with a favorable 9.9 student-teacher ratio and per-student spending of $15,367. A notable 65.14% of students qualify for free or reduced lunch, reflecting significant economic need, while chronic absenteeism stands at 12.8% — below the state average of 14.8% but slightly above the district's 11.9%.
Herndon Middle presents a striking contrast in academic performance. On the 2025-2026 SOL tests, 7th-grade Algebra I students achieved a perfect 100% proficiency rate, matching the district and exceeding the state. However, general math proficiency is critically low: only 13.33% of 7th graders and 10% of 8th graders scored proficient, compared to state averages of 51.11% and 46.86%, respectively. Reading results are better — 62.03% for 7th grade and 65.98% for 8th grade — and both improved by roughly 4 points over the prior year, though they remain below district and state levels. Science proficiency at 59.14% is slightly below the state's 64.72%.
The school's state ranking has declined for three consecutive years, from the 23rd to the 16th percentile. Much of this drop aligns with steep year-over-year declines in general math (down 25 points in 7th grade) and 8th-grade Algebra I (down 16.92 points). Despite strong resources and a low student-teacher ratio, most general education students are struggling in math, even as a small group excels in advanced coursework. The combination of improving reading scores, manageable absenteeism, and high per-student spending suggests the school has a foundation to build on, but targeted math intervention and broader access to advanced classes will be essential to reverse the downward trend.
