Baccalaureate education plays a key role in the educational pathways of research doctorate recipients. Most doctoral students earning research doctorates in the United States received their baccalaureate from institutions in the Carnegie Classification group R1: doctoral universities (very high research activity) or from foreign academic institutions. However, on a per capita basis, more graduates from Carnegie-classified baccalaureate colleges: arts and sciences focus earn a doctoral degree in science and engineering (S&E) than their peers at other types of Carnegie Classification of institutions. This InfoBrief examines the top producing baccalaureate-origin institutions of research doctorate recipients in S&E and non-S&E fields over the past decade.
