Access to courses in Carmen requires an active Ohio State name.# account. For people external to Ohio State who need access to our systems, staff can request guest accounts. Information about how to start the account creation process can be found in this Resource Center article. The article includes a link that can help you identify college staff who can assist if needed.
Once the guest accounts exist, the usual processes for adding participants to courses can be followed. In general, instructors can add people to courses that are still active. If courses are older and thus read-only, you can send a list of specific courses and the name.#s to be added to them to carmen@osu.edu. Instructional technology staff in your college may also have elevated access to assist with enrolling the guest accounts.
There is not a role in CarmenCanvas that is specifically for guests or auditors. You will need to choose which of the available roles best meets the need.
