<p>Do TAs “teach” classes at public universities? Yes. Is it more common for TAs to teach classes at public universities than at private research universities? Perhaps, but not by a signficant margin. For some strange reason, people love to exaggerate the extend to which public universities have:</p>
<p>1) Financial troubles
2) Huge classes
3) Administrative redtape that delay graduation
4) TAs teach too many classes</p>
<p>Those are definitely present at public universities, but they are just as common at private universities. The way classes are taught and class size varries very little among universities within the same peer group. Of course, comparing a tiny private LAC to a huge, underfunded public university is pointless. But in most casses, the differences are negligible.</p>
