The 5-Year joint BA/BS-MEM or BA/BS-MESc program at Yale School of the Environment allows Yale College and Yale-NUS environmental studies majors to complete both a bachelor's and a master's degree (either Master of Environmental Management, MEM, or Master of Environmental Science, MESc) in five years. This accelerated pathway provides advanced training in environmental science, policy, and management, integrating undergraduate and graduate coursework. Successful graduates are equipped for leadership roles in government, industry, NGOs, and academia. The program is open to Yale College students of any major who fulfill certain environmental prerequisite coursework; Yale-NUS applicants must be environmental studies majors. Application should be made in the senior year or up to two years post-graduation, with a gap year strongly encouraged for MEM candidates. 来源： https://catalog.yale.edu/environment/masters-degree-programs/five-year/
