Josh Moody writes: A lack of women at the helm of higher education is hardly unique to storied institutions such as Harvard or William & Mary (it's worth noting three of the eight presidents of Ivy League colleges are women). According to the 2017 American College President Survey conducted by the American Council on Education, women comprised only 30% of college presidents across the country based on numbers reported for 2016. Women of color make up a far lower portion of college presidents, a mere 5%. The survey prompts the question: why are there so few women at the top of the Ivory Tower?
