“What’s the difference between mentors and sponsors?” is a question I’ll often hear. Here are three ways to distinguish between the two:

• Speaking with Fortune, Heather Foust-Cummings, Catalyst’s senior director of research said “A mentor will talk with you, but a sponsor will talk about you.”

• Cate Huston, director of mobile engineering with Ride said “Mentors give you perspective. Sponsors give you opportunities.”

• To which I’ll add that mentors help you skill up, while sponsors help you move up.

How can you know whether you need a mentor or a sponsor?

Consider your most important career goal, and the steps you’ll need to take next to achieve that goal. What will you need help with? Do you need someone who’ll talk with you, give you advice and a fresh perspective, and help you enhance your skills? If so, a mentor can be extremely helpful. If you’re in need of someone to talk you up and connect you with bigger career opportunities, you may benefit more from having a sponsor.
