PayScale Inc. has the answers. The Seattle company, which surveys compensation, has ranked hundreds of schools by the median salaries of graduates when they are at mid-career. PayScale also ranks the schools based on average starting salaries for graduates. The top school in Wisconsin turned out to be the Milwaukee School of Engineering, with graduates on average starting careers at $54,100 a year. That’s well ahead of the second-ranked school in the category, the University of Wisconsin-Madison. UW-Madison grads start at $46,900 a year, on average.
