Time to Degree of U.S. Research Doctorate Recipients http://www.nsf.gov/statistics/infbrief/nsf06312/ http://www.nsf.gov/statistics/infbrief/nsf06312/fig1.gif For the 2003 doctorate recipients, the median total time from baccalaureate to doctorate was 10.1 years, while the median registered time was 7.5 years and the median age at doctorate was 33.3 years. The trend for the total time-to-degree measure shows a slight increase from 1978 to 1996, followed by a slight decline through 2003. A similar pattern, albeit with a peak in 1993 instead of 1996, is apparent for median age at doctorate. In contrast, the registered time to degree increased up to 1998, leveling off at 7.5 years from 1998 to 2003.
