The students whose information was affected were enrolled in an agriculture economics class in 2001. Their names, Social Security numbers and grades have been inadvertently exposed since 2001.
University information security staff members didn't learn about the problem until recently.
The university says all data has been removed from the Web site, and steps are being taken to keep it from happening again.
There's no evidence that anyone's personal information has been misused. But the university is notifying the affected individuals and telling them what steps to take to protect themselves.
