This narrative discusses problems experienced in time to doctoral degree in Sweden and steps taken. It found that long study periods and high dropout rates led to the improvement of student grants. Concomitantly, time limits were tightened up, and admission qualifications were made more stringent. Data are derived from Swedish literature. Disciplinary differences in the conduct of graduate study are noted. The study found there is less attrition and shorter time-to-degree in the natural sciences than in the humanities and social sciences and that strong faculty supervision results in lower attrition and time-to-degree in the sciences.
