Are you a student?
If you are a student and are shown this message while trying to create a new student account, it means that your school has reached their account limit for how many students can register. You will not be able to continue until the issue is resolved.
Let your teacher know.
Are you a teacher?
If you have noticed students in your class are receiving this message, you have two options to resolve it:
Increase your subscription size: Contact The Careers Department and they will be able to quickly increase your subscription to provide account access to these students. Your upgrade invoice will be generated but you will not need to wait for it to be processed to gain increased access.
Archive past students: If you have any old students accounts (who have not been active within your current 12 month subscription period) you will be able to archive them. This will free up student accounts for new students. See the guide here. Note - your teacher account will need to have Administrator access to do this change.
