If the University of Wisconsin System were graded on its faculty salaries, it would fall behind the class curve. At UW-Madison, full professors are paid about $10,000 below the median at comparable universities. UW-Milwaukee professors earn about $22,000 less than those at peer institutions, and professors at the UW Systemâ??s other institutions make about $14,600 less. â??We found weâ??ve got significant gaps between our salaries and our peer institutions at virtually every level and every type of job,â? said David Giroux, UW System spokesman.
