The five-year, dual-degree bachelor of arts/bachelor of science (B.A./B.S.) program is offered in conjunction with the School of Arts and Sciences (SAS). Students may enroll at SAS initially and then select a particular engineering curriculum at the end of the second year when they transfer to the School of Engineering. Alternatively, students enrolled in the four-year program at the School of Engineering may apply at any time prior to their final year to SAS for admission to the B.A./B.S. program. A B.S./B.S. program (in bioenvironmental engineering only) is offered in cooperation with the School of Environmental and Biological Sciences. For program details, see Five-Year Engineering Curricula in this chapter.
