Summary:
Zip code 25404 in Martinsburg, WV, is served by a single large high school, Spring Mills High School, which enrolls 1,544 students in grades 9 through 12 and is part of the Berkeley County Schools district.
Spring Mills stands out for its exceptional graduation rate of 98.9% for the 2024-2025 school year, which is 6.1 percentage points above the state average of 92.8% and also exceeds its district's rate of 97.8%. The school's state ranking has been stable over the past three years, hovering between 60th and 65th out of roughly 105-112 schools. However, this stability masks significant academic challenges. In the most recent 2025-2026 testing year, only 10.2% of 11th graders were proficient in mathematics—less than half the state average of 20.6%—and science proficiency was also low at 17.2% versus the state's 23.6%. English Language Arts is the school's strongest subject, with a 49.8% proficiency rate that is close to the state's 51.2%.
Perhaps the most concerning trend is the simultaneous decline across all core subjects from 2024-2025 to 2025-2026: math proficiency fell by 6.5 points, science by 5.9 points, and ELA by 2.8 points. This suggests a systemic issue rather than a one-year anomaly. Additionally, Spring Mills consistently underperforms its own district in every subject and every year, making it a relative laggard within Berkeley County. The combination of a near-perfect graduation rate with low academic proficiency creates a paradox—the school appears effective at getting students to completion, but instructional outcomes do not align with state benchmarks. With a student-to-teacher ratio of 16.7:1 and per-student spending of $10,938 (from 2018-2019), families should be aware that while students are likely to graduate, they may need additional support in math and science to meet college or career readiness standards.
