Internships let you sample the career of your dreams. Perhaps you will find it not what you had hoped. On the other hand, you may find it a perfect fit, and your internship may provide experience, mentors and a contact network that will help you land a job after you graduate.
Check out the Center of the American West Internships Program. We now have spots this fall with History Colorado Center and The Nature Conservancy. Requirements are a 3.0 GPA and 60 credit hours in progress at the time of application. See website for details.
