“So all the numerous college rankings out there are completely wrong and do not capture anything of importance? rather convenient of you to say so.”
Yes, rankings are, for the most part, completely wrong and do not capture much of anything. The US News methodology does not adjust for public universities in any way, and gives way too much liberty for universities to manipulate data. End result, academic powerhouses like Cal and Michigan are left out of the top 20 altogether. THE and QS are way too focused on research and international students. End result, LACs do not exist in their rankings. Brown is ranked #29 in the US, while Rice and Dartmouth barely crack the top 50. None of those rankings are reliable.
“I dont, but maybe you can enlighten me. The numbers seem to add up. All I know is that every undergrad class at Penn is taught by a faculty member and not a TA.”
I am surprised you do not know. Penn is one of the universities that manipulates data to make itself look better and inflate its rankings. Pretty unethical behavior if you ask me. All universities are clearly instructed to include graduate students enrolled in programs that also enroll undergraduate students in their student to faculty ratios. Penn omits some 7,000 such graduate students (2,200 in CAS, 2,400 in Wharton, 1,500 from SEAS and 700 from Nursing). Penn’s student to faculty ratio is 10:1, not 6:1. If it lies about something as easily verifiable as this, there is no telling what else it is lying about. Sadly, the US News does not audit data. As such, the ranking is not reliable. That’s what Stanford president Gerhard Casper explicitly says in his letter to the US News editor (link to his letter is provided in post #59 of this thread). Public universities may not manipulate data since theirs is audited by the state. Like I said, data used by the rankings are extremely unreliable, especially those reported by private universities as they are not even audited. At least the data released by public universities is audited.
As for every undergraduate class at Penn being taught by a faculty member, that’s usually the case for 95-98% of classes taught at most top universities, but seldom for 100% of the classes. TAs usually teach intro to Calculus, intro to college writing, and intro foreign language classes. That is certainly the case at Brown, Cornell, Harvard…and yes, at Michigan too. I am surprised it does not happen at Penn, although that would not be a bragging point. One does not need a Fields Medalist, or even an associate professor, to learn basic Calculus or intro to college writing. If anything, it would be a waste of a university’s resources. But beyond those intro-level classes, it is unusual for TAs to teach classes. As the title suggests, most TAs assist faculty, almost exclusively in leading discussion groups, almost always in lower level classes, where larger lecture groups are broken down into smaller discussion sections. TA involvement is part of a university’s development of future professors. How else are PhD students even to become good teachers if they do not learn in a supervised environment?
