Summary:
ZIP code 43050 contains two high schools serving grades 9–12: Mount Vernon High School, a comprehensive high school with 944 students in the Mount Vernon City district, and Knox County Career Center, with 519 students in the Knox County JVSD district. Together they enroll 1,463 high school students; Mount Vernon accounts for about 64.5% of that total and the career center about 35.5%.
Mount Vernon High School beat the Ohio state average in all six reported End-of-Course subjects in 2025–2026, averaging about 72.5% proficiency against a state average of about 63.2%. Its widest margins were in Algebra I (+16.8 points), English II (+13.2), and American History (+11.1), and its graduation rate is 97.2%. Two watch areas stand out. Geometry is the clear weak spot at 47.8%, down 7.3 points from 55.1% a year earlier and the only subject below 50% proficiency. Chronic absenteeism is 24.1% — roughly 8 points above the district's 16.1%, or about 1.5 times the district rate. The school's rank also slipped from the 75th percentile with 4 stars in 2023–2024 to the 64th percentile with 3 stars in 2025–2026, even though the Mount Vernon City district itself ranks 167 of 773, 78th percentile, 4 stars.
Knox County Career Center looks very different: its student-teacher ratio is 9.7, compared with 18.3 at Mount Vernon, and 48.75% of its students are known to qualify for free/reduced lunch. However, the data set includes no test scores, graduation rate, chronic absenteeism, or rank history for the career center, so its academic performance cannot be evaluated — those missing figures should be treated as unknown, not as evidence of weakness. Mount Vernon's free/reduced-lunch value is blank, so the two schools cannot be compared on that measure, and the available data does not support a head-to-head judgment about which school is better overall.
