But it's unclear whether the Educational Approval Board would have had the authority to oversee any complaints from Wisconsin students who enrolled in the Trump real estate seminar program, even before the governor's proposal was introduced.

The range of schools overseen by the EAB includes heavily advertised colleges like University of Phoenix, Globe University, DeVry University and Rasmussen College, along with smaller, owner-operated institutions like taxidermy, welding, massage therapy, yoga instructor and truck driving schools.

But because Trump University wasn't a degree-granting program or even a "university," it likely wouldn't have fallen under the board's purview, said EAB director David Dies.

"We were never approached or aware of any Wisconsin student signing up for any of the offerings. So we never really probed as to whether or not it needed approval," Dies said.

Dies suggested checking with DATCP, which handles consumer complaints, or the Department of Safety and Professional Services, which oversees the state's Real Estate Examining Board.

A DATCP spokesman said the agency has not received any complaints about Trump University and suggested checking with the EAB. A DSPS spokesman said he would look into the question.
