The Wisconsin Technical College System Board approved a 4.5 percent tuition increase for academic year 2010-2011 at a meeting Tuesday. The change means a student taking 15 credits of liberal arts courses at a Wisconsin technical college will pay roughly the same tuition as a student attending one of the 13 UW Colleges, the University of Wisconsin Systemâ??s freshman and sophomore campuses. Each would pay about $4,270 per year.
