Because undergraduate education is the foundation for graduate studies, it is important to know where our Nation's science and engineering (S&E) doctorate recipients are receiving their undergraduate training. Specifically, this report addresses the following broad questions: (1) What are the undergraduate origins of S&E doctorate holders? (2) Which educational institutions contribute most to the undergraduate education of recent S&E doctorate recipients? (3) What proportions of S&E doctorate holders earned their baccalaureate at a doctorate granting institution? (4) What roles do the various baccalaureate-origin institutions play in S&E predoctorate education? (5) What role do two-year colleges play in the undergraduate education of persons who later earn an S&E doctorate? and (6) Are the top-ranking baccalaureate institutions of women and racial/ethnic minorities the same as those of men and whites?
