Keith Pretty, president of Walsh College , wrote in an op-ed that his college has managed to keep its tuition increases among the lowest in Michigan . Unlike public universities, Walsh College , a private institution, has kept the undergraduate tuition increase at 2.5 percent. The reason for the low tuition increases, Pretty wrote, is generous alumni, friends and donors, many of whom provide need- and merit-based scholarships that make a Walsh education accessible for many students.
