The partnership article by a Loyola law professor Seto comes up frequently, when a better study on the same topic was published around the same time by a Stanford GSB prof, Oyer.

Oyer's study comes to similar conclusions, with Chicago emerging as the "winner" in partnerships per graduate among BigLaw firms generally and doing well among "elite" firms also. Chicago has always had a reputation for sending people to firms, so this isn't that exciting (except maybe for people looking to show up Harvard). More interesting is the finding that Chicago, Harvard and Yale are clustered at the top with the other top schools trailing well behind.
So, Yale grads demonstrate great success in a field they choose
somewhat less often than people at the other top schools, upending the folklore that YLS people are too academic/entitled/important/soft to practice law. They don't just get elite firm jobs, they stick it out and become elite firm partners according to Oyer's numbers. Chicago's success might also combat the notion that its students are too nerdy and weird to become partners and deal with clients.
Other interesting observations (interesting to me, as a partner at a law firm trying to guess who will be good and successful): the NY schools don't do as well, comparatively, despite being big feeders to much of what
is BigLaw and, more so, "elite" BigLaw. The common wisdom is also that the NY students are more "presentable" and less bookish, making them good partner candidates. It might just be that the NY firms' leverage models lead to much higher attrition, and since NY students go to NY firms, their relative success doesn't look as good. But YLS grads go to NY, too, as do many Chicago grads. BigLaw is dominated by NY firms and the NY offices of national firms. By the numbers, SLS fares the worst among historically elite schools, when common wisdom might suggest that SLS's numbers should look more like Yale's.
The data is becoming a bit stale, but most partners Oyer looked at in 2008 and 2009 are probably still partners today, which makes it relevant to people looking to get hired by those partners.
