If you are attempting to enroll a student in your school or class and receive an error saying that the email is already taken, it usually means that a student account has already been created.
Using the "Manually Add" option to enroll a student attempts to create an account. If the account already exists you will get an error. In order to enroll your student, please use the "Select From School Roster" option.
If the student is not listed in the School Roster, this likely means the student account is archived or was enrolled at a different school that used ThinkCERCA. To transfer a student into your school, please visit this support article.
