Summary:
ZIP code 43812 covers the Coshocton, Ohio area, where three high schools together enroll 877 students across grades 9–12, 11–12, and 10–12. Coshocton High School is by far the largest, with 608 students — about 69% of the ZIP's high-school enrollment — while Coshocton County Career Center (217 students, grades 11–12) and Coshocton Opportunity School (52 students, grades 10–12) are much smaller. Each has a different mission, and the amount of reported data differs sharply from school to school.
Coshocton High School shows a split academic picture in 2025–2026. English II is a clear strength at 78.4% proficient, 15.7 points above the state, followed by Biology at 75.9% and American Government at 79.4%. Math, however, is a concern: Geometry sits at 27.4% proficient, 15.9 points below the state, and Algebra I at 51.6% is 10.0 points below the state and 10.1 points below the Coshocton City district figure. Its graduation rate is 95.4%, but chronic absenteeism is high at 31.4%, compared with the district's 24.6%.
Coshocton Opportunity School presents a paradox: the highest graduation rate in the group at 97.2% and the lowest chronic absenteeism at 14.5%, yet very low test proficiency and bottom-tier rankings, which likely reflect its alternative-school role and small size. Coshocton County Career Center has the lowest student-teacher ratio at 8.3, roughly half of Coshocton High's 16.8, but no test, graduation, or attendance data, so its academics cannot be judged here. Free/reduced-lunch data are blank for all three schools, and spending is reported only for Coshocton High School for 2018–2019 ($8,510 per student), so comparisons should be made cautiously.
