I realize that this question should probably be posted in the College Wrestling section, but since the season is in full swing, I didn't think people would want to bother with it there.

Here is the question. I feel a bit dumb, but a friend of mine asked me how they separate divisions in college. I wasn't sure what to say. I think it has to do with the number of scholarships a school is allowed to give, but I am not sure. For example, Dayton is DI in basketball, but DIII in football. So, I have always thought that enrollment wasn't the detemining factor. Please let me know. I have tried googling it, but my google skills have been off lately. (could be the Natty Light, but.....nah!)

And what the heck is NAIA?

Moderators, you can move this if need be, but I just don't want to disturb the other section with my stupidity.
