This is The Economist's third ranking of executive MBA (EMBA) programmes. These pricey, part-time courses for experienced managers are more popular than ever. Yale School of Management tops the ranking this year, up from tenth in 2015. Programmes are ranked on two broad measures: personal development/educational experience and career development. On both, Yale excels, ranking first out of 65 programmes for pre-MBA salary, quality of faculty, rating of culture and classmates, while the helpfulness of its alumni network was also thought of highly by students.
