Iowa Valley Continuing Education regularly schedules courses that meet State of Iowa court-required mandates. We offer Driving Unimpaired (DUI) courses in Marshalltown and Iowa Falls each month. For the current schedule of classes go to the downloadable EdVenture course schedule, the online course descriptions, or call 641-648-8621 or 1-800-322-9235 ext. 8621 to find out if the course you need is available and the location. Iowa Falls DUI classes are now being offered during the week and Marshalltown DUI classes on the weekends to better serve our district. Iowa Code requires that students must be 18 years of age to take the DUI course.
