likely to have positive relationships with faculty.

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.

Data on 4,637 doctoral students entering at three major research universities from 1978 to 1985 in chemistry, English, history, mathematics, political science, psychology, economics, philosophy, physics, computer science, and sociology indicated that doctoral candidacy is achieved earliest in chemistry, mathematics, physics, and computer science; next in psychology, political science, sociology, and economics; latest in history, English, and philosophy.

Data measured in 1987 on 1,379 doctoral students entering Northwestern University from 1972 to 1978 in psychology, chemistry, English, history, mathematics, political science, chemical engineering, economics, philosophy, physics, sociology, theatre, and computer science show that attrition appears to be highest in English, history, political science, economics, and philosophy.
