The Graduate School accepts department nominations for several fellowships for outstanding students: the Powell Fellowship, the Cunningham Fellowship, and the Congressional Fellowship. Fellowship students are expected to be enrolled for a minimum of 12 credit hours each for the Fall and Spring semesters. Virginia Tech does not require fellowship students to be enrolled during the summer terms, though this may be a requirement of the funding agency. The Graduate School also posts information about current funding opportunities. The Virginia Tech Research Division publishes a weekly Opportunity Update, that includes notices of selected graduate and postdoctoral research opportunities and fellowships that are funded outside of the university. The Opportunity Update can be sent to you by email. Students can also conduct their own comprehensive search with COS Alert Service and have results emailed to them each week. Many other alert services, such as Grants Net, are also available.
