The InFEWS program requires five courses (two core courses plus three electives). The course requirements are in addition to, but may overlap with, the Ph.D. course requirements of your home department. There are no formal pre-requisites to apply, however a certain level of experience with quantitative analysis is necessary to succeed in the core course (roughly equivalent to Stats 121). All course work should be taken for a letter grade.
See listing of Development Engineering courses for InFEWS-eligible courses. The list of courses is the same for DevEng and InFEWS. Students who are terminal masters can take 1 elective, where as doctoral students are expected to complete 3 electives, with only one elective coming from the home department.
