<p>danas, I assume your kids attend W&M and Dartmouth because I know for a fact that Brown and Princeton have some TAs. They teach primarily intro level math classes and other elementary classes and they also assist professors in large intro level courses, but that’s the same at any elite university, no matter how small or large. I am also pretty sure that’s the case at Dartmouth and W&M, but I do not have evidence on those two.</p>
