Average time to earn a Ph.D. – 8.2 years

In the New York Times, Joseph Berger examines recent attempts to  shorten the ascent to a Ph.D. He explains:

For those who attempt it, the doctoral dissertation can loom on the horizon like Everest, gleaming invitingly as a challenge but often turning into a masochistic exercise once the ascent is begun. The average student takes 8.2 years to get a Ph.D.; in education, that figure surpasses 13 years. Fifty percent of students drop out along the way, with dissertations the major stumbling block. At commencement, the typical doctoral holder is 33, an age when peers are well along in their professions, and 12 percent of graduates are saddled with more than $50,000 in debt.
