If you have a subscription that subscription covers getting the latest 2015 release. Unless you have some other arrangement, the upgrade is not based on when your license renews, but instead when the upgrade is released, which it is.
If you wish to contact Adobe:

The question was more so asking about workarounds to get CC 2014 to open CC 2015 projects. As I specified in my post, the school cannot update to CC 2015 for another two months due to their contract with Adobe.
That does not sound right - the whole concept of the subscription model is to update as new revisions are released. You should talk to Adobe - I provided the contact info in my response.
Okay, thanks. I'll try contacting them by phone.
