In pursuit of the PhD

"What percentage of graduate students entering PhD programs in the arts and sciences at leading universities actually complete their studies? How do completion rates vary by field of study, scale of graduate program, and type of financial support provided to students? Has the increasing reliance on Teaching Assistantships affected completion rates and time-to-degree? How successful have national fellowship programs been in encouraging students to finish their studies in reasonably short periods of time? What have been the effects of curricular developments and shifts in the state of the job market? How has the overall "system" of graduate education been affected by the expansion of the 1960s and the subsequent contraction in enrollments and degrees conferred? Is there "excess capacity" in the system at the present time?" "This major study seeks to answer fundamental questions of this kind.^ It is based on an exhaustive analysis of an unparalleled data set consisting of the experiences in graduate school of more than 35,000 students who entered programs in English, history, political science, economics, mathematics, and physics at ten leading universities between 1962 and 1986.
