Summary

Cosby High, in Midlothian, VA, is a large public high school enrolling 2,507 students in grades 9–12 as part of Chesterfield County Public Schools. The school currently ranks 70th out of 331 high schools statewide (79th percentile, 4 stars) — solidly above average, though a significant fall from its historical top-10 standing (6th–8th from 2015 to 2019). Despite the ranking slide, core student outcomes remain excellent: the 2024-25 graduation rate was 97.3% (vs. 89.2% district and 92.3% state), the dropout rate was just 2.6% (vs. 8.5% district), and chronic absenteeism was 7.3% — less than half the district's 16.1%.

Cosby High also delivers strong test performance. On 2025-26 SOL exams, it far exceeded state averages in 9th grade Algebra I (92% vs. 80%), Biology (93% vs. 86%), and 12th grade English Reading (100% vs. 70%). History scores are exceptional, especially 12th grade VA/US History (93% vs. 54% state). The main weak spots are 11th grade Writing (68% proficiency vs. 80% statewide) and 9th grade Geometry (81% vs. 86%). The school also ranks particularly well for Hispanic students (37th of 242) and African American students (48th of 242) statewide, and its English Learner subgroup was ranked #1 in Virginia in 2022-23 — evidence that Cosby High serves a wide range of learners well.

Cosby High is a clear academic standout within its district. While Chesterfield County Public Schools overall earns only 2 stars, Cosby High and Midlothian High are the two highest-performing schools in the district, with nearly identical outcomes. Cosby High has a slightly higher graduation rate (97.3% vs. 96.5%) and lower chronic absenteeism (7.3% vs. 8.8%) than Midlothian High, though Midlothian High edges it out on Writing and Geometry. Cosby High also does more with less: its per-student spending of $7,124 is the lowest among nearby high schools — about $1,600 less than Manchester High — and its student-teacher ratio of 15.9 is on the higher end. One area that deserves attention is the school's Military Connected students, whose state ranking has fallen from the 70th percentile in 2023-24 to the 25th percentile in 2025-26 — the only subgroup currently earning one star.
