First-time graduate student enrollments were up 3.9 percent last fall from a year earlier, according to a new report from the Council of Graduate Schools. Each of the last four annual surveys has found that enrollment has increased, but 2015’s bump was one of the biggest since 2009. Contributing to that growth was an increase in the share of underrepresented minority student enrollees, which could be a response to national conversations and institutional initiatives on faculty diversity. At the very least, it’s a possible start to broadening the eventual faculty applicant pool.
