RALEIGH, N.C. -- North Carolina's state auditor says top officials at one public university violated state travel policies by exempting themselves from the need for advance approval.

State Auditor Beth Wood's office released a report Thursday about the practice dating back to 1996 at the University of North Carolina at Greensboro. The school's chancellor, top academic officer, deans and others were allowed to travel without the prior approval required under state policy. The audit says their travel expenses were more than $450,000 between 2011 and 2013. Eight other University of North Carolina universities that were checked followed the rules requiring senior administrators to get approval from their supervisor or another senior administrator.

UNCG Chancellor Linda Brady says the school accepts the auditor's recommendations on getting prior travel approval.
