Time to degree for Ph.D. students is measured from the time students enter their doctoral programs until the time they complete their Ph.D. degrees; it is based upon a rolling average over a three-year period.

On average, Ph.D. students at UC take about the same amount of time to complete their degrees as students at other AAU research universities.

However, Ph.D. students in the arts and humanities take longer to complete their degrees than Ph.D. students in other fields. This may be due to a number of factors: the additional time arts and humanities students spend as teaching assistants, the more individual nature of their dissertation research, the fact that they must often meet significant language requirements depending on their major and the fact that they more often interrupt their studies for financial or other reasons.
