Of the 100, 87 have at least 1 degree. Below we take a look at the top 15 universities that educated the 100 women on the list both by number of graduates and number of degrees. What really stands out though is that when it comes to promoting education for women, there seems to be a pattern: 45 of the 100 women have at least 1 degree from one of these 15 universities. Another thing to note is that only one Asian institution makes the list. With 3 graduates--Margaret Chan, director-general of the World Health Organisation; Chua Sock Koong, the chief executive of SingTel; and Ho Ching, chief executive officer of Temasek Holdings--the National University of Singapore is firmly in the list of the top 15 universities that educated the world's 100 most powerful women.
