INBRE programs are required to track the career paths of its undergraduate research fellows for at least 5 years after they complete the research experience. SD BRIN tracks fellows by word of mouth through the institutional liaisons and by access to the National Student Clearinghouse database of all students enrolled in higher education. In addition, SD BRIN solicits personal e-mail addresses from the fellows so that it can contact them if/when their institutional e-mail addresses have lapsed.
