Nationally, men in colleges and universities currently outpace women in earning degrees in physics, engineering, and computer science (PECS) by an approximate ratio of 4 to 1. To better understand the factors driving these gaps, NYU researchers analyzed bachelor’s degrees awarded in the US from 2002-2022, and found that the most selective universities by math SAT scores have nearly closed the PECS gender gap while less selective universities have seen it widen dramatically.
