As a physics faculty, I have two jobs. The first is coach. I help students wrestle with concepts and ideas. That makes me something like Gregg Popovich of the San Antonio Spurs, but with more equations. I'm also an evaluator. I determine how well students understand the material I've taught them. Yes, I find it odd that I do both of these things. It's like having Popovich coach the team and referee the game. But that's how it is in education.
