There are two options for creating student accounts as an educator: adding students them individually and creating student accounts from spreadsheets. Each option requires that you have the students' email addresses. If you do not have access to student emails, please review how to register as a student to see how you can guide students through self-registration.
If you would like to lead students through their own account creation, confirm with your customer success representative or by emailing support@overgrad.com that student registration has not been locked at your school site to prevent duplicate accounts.
