of 1,111 Virginia Elementary Schools

Better than 20% of Virginia elementary schools

Summary

R. Dean Kilby Elementary is a PK–5 school in Woodbridge, VA, serving 613 students as part of Prince William County Public Schools. The school serves a predominantly low-income population, with about 71.8% of students qualifying for free/reduced lunch. Kilby currently ranks in the bottom fifth of Virginia elementary schools — 890th out of 1,111 (20th percentile, 1 star) — and trails both the district and state averages on Virginia SOL assessments in nearly every subject and grade level.

Compared with its neighbors, R. Dean Kilby Elementary's low ranking is striking. Among ten nearby Prince William County elementary schools, only Marumsco Hills Elementary ranks lower (11th percentile), while most others sit in the middle or upper half of the state — including Old Bridge Elementary (81st percentile), Dale City Elementary (71st), and Occoquan Elementary (68th). Perhaps most remarkable is Martin Luther King Junior Elementary, which shares the same address but ranks at the 62nd percentile with a similar poverty rate. In 5th grade science, for example, MLK Jr. posts 79.2% proficiency versus Kilby's 49.4% — evidence that high poverty alone doesn't determine outcomes.

There are encouraging signs, too. Kilby's chronic absenteeism rate (12.9%) is better than the district (13.8%) and state (14.8%) averages, and per-student spending ($13,390) and the student-teacher ratio (14.1) are favorable compared with many higher-ranking neighbors. The school also shows strength with certain subgroups: African American students rank at the 61st percentile statewide, up from the 34th percentile two years earlier. Kilby has improved from the 4th percentile in 2016-2017 to its current range, though progress has plateaued in recent years. The gap with MLK Jr. — same district, same community, similar demographics — suggests that targeted instructional improvements could meaningfully lift Kilby's outcomes.
