There are many career options for people with Ph.D.-level education. Ph.D.s from both the humanities and STEM disciplines frequently go on to successful careers in government, marketing, K-12 education, non-profits, industry, consulting, entrepreneurship, university administration, and many more fields.
To get a better idea of possible career routes for Ph.D.s beyond the professoriate, we highly recommend visiting Beyond the Professoriate/Beyond Grad School.
In addition, the site features stories and the actual resumes and cover letters of Ph.D.s and ABDs who successfully made the transition from academia into a career outside the academy.
