Summary:
Zip code 22172 is served by exactly one elementary school: Triangle Elementary, a PK-5 school with 795 students in Prince William County Public Schools. Since no other elementary school exists in this zip code, all area-level metrics reflect this single school's performance.
Triangle Elementary has improved its state percentile over three years, moving from the 13th to the 21st percentile, though it remains in the bottom quarter of Virginia elementary schools with a one-star rating. In 2025-2026, the school averaged roughly 60.8% proficiency across eight SOL assessments, compared to about 76.6% for the district and 71.6% statewide. Its strongest relative performance came in 4th grade Virginia Studies at 67.52% proficiency, just three points below the state average. The most challenging area is 5th grade math at 52.07% proficiency, about 20 points below the state and 26 points below the district. Math proficiency also declines as grade levels increase, from 70% in 3rd grade to 55% in 4th grade and 52% in 5th grade. Encouragingly, 3rd grade reading improved by 8.25 points and 3rd grade math by 6.81 points year over year.
Context matters when interpreting these results. About 70.82% of students qualify for free or reduced lunch, and the chronic absenteeism rate of 16.4% exceeds both the district (13.8%) and state (14.8%) averages. The school maintains a student-teacher ratio of 14:1 and spends $11,726 per student. While Triangle Elementary remains below district and state averages in every subject, its recent gains in lower-grade reading and math, along with its relative strength in Virginia Studies, provide a foundation for continued improvement.
