This Environmental Health course was developed in partnership with the Association for Prevention Teaching and Research, the U.S. Centers for Disease Control and Prevention (CDC), and Peoples-uni. This course is co-sponsored by: the International Society of Doctors for the Environment, Physicians for Social Responsibility, and the University of the Incarnate Word. Like all NextGenU courses, it is competency-based, using competencies from the Association of Schools and Programs of Public Health. This course covers the CEPH-related competency “Advocate for political, social, or economic policies and programs that will improve health in diverse populations [D2:14].” This course uses learning resources from world-class academic and governmental organizations such as the International Labour Organization, the University of Washington, Yale School of Public Health, the World Health Organization, the U.S. CDC, and the U.S. National Institutes of Health. Our original course developer was Lindsay Galway, and our Advisory Group was: Ryan Allen, PhD; Kristian Dubrawski, PhD; Sylvia Struck, PhD; and Tim Takaro, MD, MPH, MSc.
