The OCCC has member representatives from each college who can serve as guides in designing a Core course. (OCCC website with members names and contact information). Contact any member and ask them to help you with an understanding of the Core and how a Core course operates.
The Director of the Core is designated to serve as a support person for anyone who wants to create a new course in the Core. (link to About page in website)
This website has multiple links that can lead to self-learning how to create a course in the Core. (link to all previous links and pages)
