Summary:
Grant County Schools is served by a single high school, Petersburg High School, which enrolls 582 students in grades 7 through 12 in the small town of Petersburg, West Virginia. This school is the sole provider of secondary education in the district, meaning its performance directly reflects the district’s overall academic health.
For parents, the most striking takeaway is the dramatic difference between the school’s middle school and high school results. In 7th grade, students actually outperform the state average in both math (38.2% proficient vs. 36.7%) and English language arts (49.0% vs. 45.9%). However, by 11th grade, proficiency collapses: math drops to just 9.5% (state: 20.6%), ELA falls to 31.9% (state: 51.2%), and science sits at a critically low 11.8% (state: 23.6%). This suggests the school’s early grades are solid, but students lose significant ground during high school. The school’s overall ranking reflects this struggle—it plummeted from the 68th percentile in 2024-2025 to the 5th percentile in 2025-2026, a single-year drop of 64 positions that dropped its star rating from 3 to 0.
Despite these academic challenges, the school maintains a graduation rate of 93.2%, slightly above the state average of 92.8%. With a favorable student-teacher ratio of 14:1 and per-student spending of $10,294, resources are adequate, yet they are not translating into high school achievement gains. The data points to a clear need for targeted intervention in upper-grade math and science, as well as a question of whether the ranking collapse is a true trend or a statistical anomaly. For parents, this means the middle school years are a relative strength, but they should be prepared for a challenging transition into high school academics.
