Deciding on a college major means having to consider which subject complements your strengths and your interests, and what degree will get you a job down the road. Equally important is how much money you’ll be making, because you’ll have to pay off a load of student debt too! So, how can you tell which major will be valuable to employers in the future?

Research firm PayScale took a deeper look into what skills hiring managers are looking for in fresh hires — and it turns out that 69% of them consider relevant course work as a significant differentiator when they're choosing between candidates for job openings. As Katie Bardaro, lead economist at PayScale points out, "Unless you go to a top-20 brand name school, what matters most to employers is your major."

Using PayScale's study of 120 college majors and their job growth projections through 2020 from the U.S. Bureau of Labor Statistics, we've put together a list of the most valuable majors in the current marketplace. Each one of the majors is ranked using a combination of median starting pay, median mid-career pay, expected salary growth, and current and future growth in job opportunities.
