Summary

R. Dean Kilby Elementary is a public magnet elementary school in Woodbridge, Virginia, serving grades PK-5 with a total enrollment of 604 students. Despite being part of the Prince William County Public Schools district, which is ranked 42 out of 129 school districts in Virginia, R. Dean Kilby Elementary has consistently ranked in the bottom 20% of Virginia elementary schools over the past 10 years, with a 1-star rating from SchoolDigger, indicating it is among the lowest-performing elementary schools in the state.

The school's performance is mixed, with African American and English Language Learner students performing relatively better, ranking in the top 50% of Virginia schools, while the school struggles with the performance of female, male, and low socioeconomic status students, ranking in the bottom 20-30% of the state. Additionally, R. Dean Kilby Elementary has experienced high chronic absenteeism rates, ranging from 11.1% to 20.0% over the past few years, which is significantly higher than the state and district averages. The school's proficiency rates in SOL (Standards of Learning) assessments for mathematics, reading, science, and Virginia Studies are consistently lower than the Prince William County and Virginia state averages, often by 10-20 percentage points.

Compared to the nearby elementary schools in the same district, such as Old Bridge Elementary, Dale City Elementary, and Featherstone Elementary, R. Dean Kilby Elementary significantly underperforms. Despite increased per-student spending and a more favorable student-teacher ratio, the school has not been able to improve its academic outcomes, suggesting the need for a more comprehensive approach to address the underlying challenges.
