People with these college majors get the biggest pay raises

White HouseGovernment majors can expect to say a big pay raise once they've got some experience under their belts.

In some jobs, you have to wait until you've got some experience under your belt before you begin to see a substantial payday - but when it comes, you'll be thankful you paid your dues.

PayScale recently looked at salary data from this year's College Salary Report and analyzed the difference between starting (less than five years of experience) and mid-career (10 or more years of experience) pay by college major.

While salary-growth potential shouldn't necessarily encourage students to pursue a particular major, it's an important consideration to make when thinking about the future.

Here are the 20 college majors with the greatest increases in wage between early- and mid-career.
