Bill Cassidy actually said...

Now, with teachers, what are the top two variables?

Yes, I did. But it's not the teacher. It's not the principal. It's not the school. It's the parents' educational level?

I'm not a teacher. Well, I am a teacher. I teach with a medical school, and so I have some experience.

Is there a second variable you would throw in there? Because that was not correlated with the teacher.
