Retired machines for university users

I am a new admin for my university group. I was told that university users can have access to retired machine (in addition to the two for everyone). I can’t figure out how it works. Any help or pointer would be much appreciated.

After hacking our invite challenge, you can apply through the universities section of the dashboard. Students can submit an application on behalf of their university, however we require an authorization form to be completed and signed by a faculty member for all applications.

You will also receive an educational discount on access to the retired machines, VIP servers, etc.
