Where is 61% coming from? According to LSAC their bar passage was 96% http://www.lsac.org/LSACResources/Publications/2011OG/aba4127.pdf
That doesn't mean Phoenix is a great school or bad school. Whether someone passes the bar or not is largely up to the individual.
Berkeley had an 87% bar passage rate last year. 28 Berkeley grads failed the bar first time around does that make Berkeley a bad school? No it doesn't those people probably didn't do the requisite studying and will likely pass the second time around. Michelle Obama a Harvard Grad failed the bar the first time around and Harvard is not a bad school. She is not doing to bad for herself either despite failing. The Bar is something you need to start a legal career, but there are plenty of atrocious licensed attorneys that passed the first time. There are also many great lawyers and judges that failed first and even second time around.
If you attend Phoneix or any ABA school odds are you will pass the bar. Passing the bar does not mean you will get a job and that is a whole other struggle. Even if you get a job you will need to perform and perform well to keep it. Law is a competitive profession and no matter where you go it is a long road. It certainly helps to go to Harvard, Yale etc, but 99% of the population can't get into the Ivy League. Going to a non-elite school you will have an uphill battle ahead of you, but it is a winnable battle if your willing to put the time and effort in.
