Summary

Mary Williams Elementary is a public magnet elementary school located in Dumfries, Virginia, serving grades PK-5 with a total enrollment of 697 students. The school is part of the Prince William County Public Schools district, which is ranked 42 out of 129 school districts in Virginia and has a 3-star rating from SchoolDigger.

Despite the school's relatively low student-teacher ratio, Mary Williams Elementary has consistently ranked in the bottom half of Virginia elementary schools over the past 10 years, with academic performance on SOL (Standards of Learning) tests generally below the district and state averages, particularly in mathematics and English reading. For example, in the 2024-2025 school year, the percentage of 3rd-grade students proficient or better in SOL Mathematics was 74.53%, compared to 77.82% for the district and 72.89% for the state. The school has also experienced high rates of chronic absenteeism, ranging from 12.5% to 20.0% over the past few years, which is higher than the district and state averages.

Interestingly, Mary Williams Elementary performs significantly worse than the nearby John F. Pattie Senior Elementary and Covington-Harper Elementary, which are also part of the Prince William County Public Schools district. For instance, in the 2024-2025 school year, the percentage of 3rd-grade students proficient or better in SOL Mathematics was 94.12% at John F. Pattie Senior Elementary and 81.55% at Covington-Harper Elementary, compared to 74.53% at Mary Williams Elementary. Despite the higher per-student spending of $8,572 in the 2020-2021 school year, which is higher than the district average, Mary Williams Elementary appears to be a struggling school within the Prince William County Public Schools district, and addressing the identified areas of concern should be a priority to improve student outcomes.
