majors of any of the university's four colleges, including all arts-related majors (both fine and performing), all humanities majors, all social science majors, the university's communication program, and the economics and information science programs. College of Health, Education and Social Welfare The CHESW oversees the university's professional programs, including education, healthcare management, social work, and the joint nursing programs that the university maintains with the nearby Bellin College of Nursing. College of Science, Engineering and Technology The CSET oversees all science-related majors, in addition to mathematics and the university's Engineering Technology program. Removal of interdisciplinary requirement Until 2017, the university mandated that students complete at least one interdisciplinary major or minor in order to ensure a more well-rounded education. As an example, a student in a major classified as disciplinary, such as music, accounting, biology, or English was required to complete either a double major or a minor in a field with some professional applications considered interdisciplinary, such as business administration, communication, or computer science. In late 2017, faculty members on the school's University Committee (of the Faculty Senate) proposed to remove the requirement in the interest of streamlining the academic process, a proposal that was controversial but ultimately passed. Top majors The university's top majors, by degrees granted, are: Undergraduate: Business Administration Psychology Integrative Leadership Studies (an online-only BA/BS program targeted at non-traditional students) Human Biology Nursing (all tracks) Graduate: Master of Social Work Master of Sustainable Management Campus The 200-acre campus is on the northeast side of Green Bay, overlooking Lake Michigan's Green Bay. Much of the campus is composed of natural areas, with the campus bordered on one side by the bay and on the other by the Niagara Escarpment. A system of circular roads (North, East, and South Circle Drives) surrounds the central campus and are the main thoroughfares for traffic on campus, in addition to a few smaller roads that connect the Circle Drives with parking lots. The Cofrin Memorial Arboretum forms a natural boundary of 290 acres encircling the campus. It offers recreation, field trips, and research projects. The purpose of the Arboretum is to restore and preserve some of Wisconsin's native ecological communities and to offer an opportunity to enjoy and appreciate nature. It has more than six miles of trails open to the public. The David A. Cofrin Library sits at the heart of campus, and is one of the tallest buildings
