Internal auditing of the University of Wisconsin System has been cut in recent years, a system review found, raising questions about its strength to sniff out waste and mismanagement on the state’s campuses. But a committee of the UW Board of Regents agreed Thursday that the cut was necessary.

The committee also voted on a recommendation that all university employees be required to provide a doctor’s note if they are out sick for more than five days, saying the Paul Barrows controversy at UW-Madison made the move necessary.
