You must obtain class rosters by entering on-line services for the Office of the University Registrar (http://www.ureg.ohio-state.edu/Indexes/faculty-staff.html).
When you reach the above site click on "class rosters via the web." They will then ask you for your username (name.#) and password. Enter those according to the instructions.
If you need assistance, please call Faculty Services at 419-755-4236.
