Certification and Training Calendar

Our professional development courses are split into two groups, Certification and Training. Depending on the level (training or professional level), certification can either be obtained through a workshop or through a peer review process. The entry level certification courses below (CIG/CIH) help students to complete some of the required portions of their certifications, while Training courses offer the chance to expand your knowledge in that a specific topic area. Please take a look at the Course Listings below for courses available in your area.  This course list is updated weekly.
