<p>Not a phenomenon unique to the Ivy League research universities, perhaps common to CS departments.</p>
<p>A dear friend of mine, currently an undergrad at Carnegie Mellon University (which has a CS department that is peer to those of MIT, Stanford, and Berkeley), is a T.A. for “Operating System Design and Implementation,” which is one of the most advanced and difficult CS courses, a gold star on any resume.</p>
<p>He likewise teaches discussion sessions, holds office hours, and grades exams. Both undergraduates and graduates were enrolled in this class, the latter making up the majority.</p>
<p>So, at one of the nation’s premiere research universities, you’ve got an undergrad TA’ing an advanced course for mostly grad students.</p>
<p>I have no problem with this, since I know my friend is supremely knowledgeable and exact, a clear and patient instructor. Others, however, may.</p>
