This report looks at trends from 1973 to 1993 in new science and engineering doctoral degree recipients' post-graduation plans in order to note changes in the proportion planning postdoctoral appointments (postdocs). Examination of this question found that between 1973 and 1993 the proportion of doctoral graduates with "definite plans" at the time of graduation declined nine percent from 75 to 66 percent. The decline was much steeper between 1988 and 1993 (8 percentage points) than between 1973 and 1988 (1 point). "Definite plans" were defined to mean a commitment for a job or postdoctoral appointment. In addition, the proportion of graduates planning an academic job declined from 51 percent in 1973 to 32 percent in 1993 while those whose definitely planned option was the postdoc increased from 21 percent to 39 percent over the same period. The review also looked at a sample of doctoral graduates from May/June 1990 with definite plans for a postdoc and examined what they were actually doing in September 1991. Of the sample, 59 percent were on post-doctoral appointment 15 to 16 months after graduation with the proportion higher in the life sciences that in the physical sciences. Finally, the analysis describes the number and characteristics of those reporting that they held postdocs in 1991, regardless of their plans at the time of degree award. Contains four tables. (JB)
