Being well into middle-age, I am not entirely up to date with the latest scoop on law schools, and, when I was a young pup, it seemed like any gentleman with decent grades from a decent school could go on to Yale or Harvard Law, depending on their football-team preference.
Grad schools are all about maximizing your options, except in medicine where they all teach the same thing in the same way, all take the same exams, and all basically flunk out the same considerable numbers of students, despite the monumental obstacles to admission (straight As in the science and math requirements, etc). Or Divinity School, where it's an entirely different ball game and the final arbiter is a supernatural being. Otherwise, grad schools are trade schools, whose focus is on The Job - whatever it is one wants.
And The Job, or job choice, depends on the ranking of your school, and your rank in the class. There are plenty of Law School rankings, and all are based on varying criteria and vary somewhat, accordingly. If you want to be a local country lawyer with a shingle on the front door and doing simple wills and real estate, it doesn't matter where you go to school - and law isn't exactly rocket science except at the competitive levels. Anyone can learn the basics and the Latin lingo. And at law firms, one becomes basically an apprentice to learn the practical specialty trade, and where you either try to make Partner, or take your skills elsewhere.
I like the Princeton Review Rankings, which are more detailed that the others. Law School 100 has a ranking which is probably consistent with that of most lawyers. US News ranks everything, in their own way, but you cannot ignore their lists. Of course, there are critiques of their highly-promoted rankings. Personally, I like the University of Texas, but partly because Texas produces the most lovely women, with the most charming accents and the most intriguing feminine ways, in the world... except, well, there's Georgia, too. Anyway, the Yale Law gals are dogs, with attitudes.
