Schools in Zip Code 20165

Zip code 20165 in Virginia is served entirely by Loudoun County Public Schools, a highly rated district ranked 18th out of 131 districts statewide. The zip code contains 7 public schools — 5 elementary schools, 1 middle school, and 1 high school — enrolling about 5,510 students total.

Among the elementary schools, Lowes Island Elementary is the strongest overall, ranking in the 80th percentile statewide with the lowest chronic absenteeism rate in the area at just 6.5%. Algonkian Elementary is close behind (79th percentile) and posted the top 5th-grade science proficiency at 87.2%. Horizon Elementary also performs well at the 73rd percentile. At the other end, Countryside Elementary (45th percentile) and Potowmack Elementary (31st percentile) serve higher-poverty populations — 51.4% and 85.2% free/reduced-price lunch eligibility respectively — and have lower proficiency rates. Notably, Potowmack spends the most per student ($22,049) but ranks lowest, showing that higher spending alone does not guarantee higher performance.

At the secondary level, River Bend Middle is the standout for improvement, moving from the 43rd to the 58th percentile, with a perfect 100% proficiency rate in 7th-grade Algebra I and 8th-grade Geometry. However, grade-level 8th-grade math proficiency is just 45.9%, revealing a large gap between accelerated and on-grade students. Potomac Falls High graduates 94.9% of students — above the state average — and posts 100% proficiency in Chemistry, but its overall rank sits at the 47th percentile with concerning 11th-grade Biology results. Across the zip code, chronic absenteeism is a clear warning sign: schools with lower attendance, like Countryside (18.1%) and River Bend (16.4%), tend to trail their peers academically. In a single zip code, families can find very different school experiences, so it is worth looking closely at each school's data.
