The commission found that women have doubled their share of bachelor’s degrees in science and engineering over the last four decades. In 1966, they earned one quarter (24.8 percent) of bachelor’s degrees in those fields, while in 2004, they earned half (50.4 percent). Over the same time span, women also gained a dramatically greater percentage of master’s degrees – 13.3 percent in 1966 versus 43.6 percent in 2004. At the doctorate level, the increase was especially noteworthy – 8 percent in 1966 compared to 37.4 percent in 2004.
