Content Questions

How to check if your university will accept credits from UPI study?

To ensure your UPI Study courses transfer to your university, check two things:

1) Is your university listed? If it's one of the 1,500 universities listed with NCCRS, you're all set.

OR

2) Check your university's credit policy. If it says they accept credits from "regionally accredited" universities, you're good to go! As long as you meet one of these criteria, your courses should transfer without a hitch.

Check the list of colleges here.

Membership Questions

Will there be hand holding to help transfer courses?

Yes, that is what differentiates UPI. With each student their advisor will guide them on how to move forward.
