Caledonia-Mumford students can explore a working life before leaving high school. The district’s Work Co-Op program offers eligible juniors and seniors paid or unpaid internships for school credit, combining workplace hours with seminars, reflection journals, and a portfolio. Students provide their own transportation to off-campus internships. A separate career-shadowing option pairs students with a professional for a day or part of a day. Academic routes include dual-credit courses with local colleges and Advanced Placement subjects such as computer science, art and design, chemistry, and calculus.
The district occupies one campus in Caledonia, southwest of Rochester, with three school buildings. Children attend elementary school from prekindergarten through fifth grade, middle school in grades six through eight, and high school in grades nine through twelve. The elementary building opened as Caledonia High School in 1939; the present high school opened in 1998.
