II-27b: Median Number of Years Spent by Humanities Ph.D.’s in Their Doctoral Programs, by Discipline, Graduation Years 2003–2012*

* Time in doctoral program is measured as the difference between the month and year the doctorate was granted and the month and year the doctoral program was started, including the most recent master’s degree if earned at the same institution.

The Survey of Earned Doctorates (SED) offers researchers several ways of measuring “time-to-degree.” The survey yields data on both time since completing undergraduate studies and time since first taking a graduate course. The Humanities Indicators uses as the basis of its calculation of time-to-degree a third type of data supplied by the SED: the date the student began studies in the program that conferred his or her doctoral degree (or master’s degree, if earned at the same institution as the doctorate; see question A8 on the 2012–2013 questionnaire). The difference between this date and the date of doctorate completion yields a measure of time-to-degree that is not inflated by what for some students are lengthy pauses between degrees.
