CRA study: How long does it take to get a PhD in CS? Longer for women and minorities
Really interesting new study out of Computing Research Association (CRA). How long does it take to get a PhD in CS? How does that compare to other STEM disciplines? How does it differ based on gender or minority status?
Table 3 and Figure 1 show the median time to complete a Ph.D. since first beginning a graduate program, for each subgroup, for each cohort.
Gender . Women take longer than men. This is true in both cohorts; there is a larger difference (almost a year) in the second cohort.
Citizenship status. In the earlier cohort, students on temporary visas take less time than citizen or permanent resident students. In the later cohort, the median times of the two groups are exactly the same.
Minority status. Students from underrepresented minorities (URM) – that is, racial and ethnic groups underrepresented in computing – take longer than majority students to complete a Ph.D.. In the first cohort, the difference is almost two years; in the second cohort it is close to one year.
Carnegie Class. Eighty percent of doctorates in computing are granted by “Very high research activity” institutions; students at those institutions take noticeably less time to complete their degrees than those at the less-research-intensive institutions.
