What is co op in high school?

In high school, a co-op, short for cooperative education, is a program that allows students to gain work experience while earning school credit. Students typically spend part of their school day working at a job related to their interests or career goals, and the other part attending regular classes. The work experience is supervised and often integrated into their academic studies, providing a real-world application of what they're learning in the classroom. The specifics of the program (hours, scheduling, types of jobs allowed) vary from school to school and district to district.
