Should you capitalize college majors?

Whether you are writing a website bio for your small business or for executives at a large corporation, the answer is the same. Use lowercase.

The AP Stylebook Ask the Editor section says the following:

Q. Where do I find the rule on capitalization for college majors and minors? I am instructing my students to follow the rule for course titles. Thanks! from BALTIMORE, MD on Jan 25, 2011
A. College majors are lowercase unless they include proper names. She majored in French, with minors in mathematics and American history.

Be consistent and always follow the rule, and if you don’t yet have an online copy of the AP Stylebook (with Ask the Editor and Webter’s New World College Dictionary Fifth Edition), get one.
