I wrote an answer to this question concerning how to verify whether someone went to the college/university that their resume says they went to:
The correct answer (in part) is to refer the OP to "National Student Clearinghouse" which is a non-profit that handles most of these type of student degree verification services.
I'm in a bit of a conflict because I'm not very happy that even my own university and alma mater have essentially sold my data to a third-party which then resells them to students and employers. I find this a morally distasteful business model and I don't want to reward NSC with a direct link to them.
But back in the Real World®, people do need to know about their existence.
Suggestions?
