The information was inadvertently left in a publicly accessible computer folder from 2003 to November of 2008. A former applicant found the mistake while searching for information on himself.
The school says that even after the data was removed from a university server, some of it remained available through Google until just a few months ago.
Last week, the school contacted Google to clear the information, and informed applicants of the issue, urging them to contact credit reporting agencies.
