About Career Online High School

Pima County Public Library's Career Online High School (COHS) offers adult students a chance to earn a nationally-accredited high school diploma while preparing for a career in one of nine high-demand, high-growth fields.

The program offers the flexibility to take classes online and access schoolwork 24/7. Learners also receive support and free educational resources at their local library.

To be considered for the program, applicants must successfully complete an online readiness survey and prerequisite course, followed by an interview with library staff.

Once enrolled in the program, COHS pairs each student with an online academic coach, who provides the student with an individual career path, offers ongoing guidance, evaluates performance, and connects the student with the resources needed to master the courses. Students are given up to 18 months to complete the program.

The program is offered at no cost to the student.
