Class sizes vary depending upon the course, enrollment and the faculty’s determination of the most appropriate mode of instruction. We do not anticipate an increase in class sizes at any of the three campuses. At UWM at Waukesha, the average class size is currently about 25 students. At UWM at Washington County, it is 24. At UWM, the average class size is 26, and more than 40 percent of our undergraduate classes have 19 or fewer students in them.
