<p>Are all classes taught by professors? Are some taught by assistants?</p>
<p>a lot of classes are taught by people working in the government which is good because they have personal experience</p>
<p>As far as I know, all classes are taught by professors… I haven’t had or heard of anyone ever having a TA as an actual instructor, and am pretty sure the university doesn’t allow assistants to teach classes.</p>
<p>The only thing apart from this that I can think of is that some intro science courses have labs and the lab portion is often led by a PhD student who is actively involved in research here as well.</p>
<p>I agree^…in contrast to a lot of other schools I haven’t heard anyone complain about TAs teaching a lot of classes…also there seem to be very few really bad teachers at American and most of them are in the basic required classes</p>
