All of the community colleges in Iowa are participating in a joint project to develop common numbers for all of our courses. Because of this initiative, all of our course subject names and most of our course numbers at DMACC changed effective fall semester, 2006. This page will help you find the new course subject names and the new numbers

Note: If and how DMACC courses transfer to other colleges and universities is determined by the receiving institution.
