Duke has only two undergraduate colleges, Trinity (arts & sciences) and Pratt (engineering). Most students interested in business choose to major in econ with the finance track, and the Markets & Management Studies certificate* is popular too.
Duke’s undergraduate programs in environmental science and public policy are offered in association with the Nicholas School and Sanford School, respectively, but they’re housed within Trinity.
*Certificate programs at Duke require more courses than a minor but fewer than a major.
