Check out the bar's site if you're interested in the statistics. It break's the results down very well, including
ABA schools, Accr bar examiner's schools, correspondence, and just unaccredited schools.
Without question ABA approved schools have the highest pass rates. But a solid second is correspondence schools...especially Concord, taft, and a christian one called oakbrook. Taft boasts a 75% pass rate for all takers(25% dont pass no matter how many times they tried). This, however, is quite high considering that these three schools best even bar examiner schools. Thus its easy to follow that the quality of the education is there. Also remember that the quality of the student, in general, is not as likely to be the "type A" wiz, the one who nearly aces everything as an undergrad in order to attend the best law school. I believe the ABA pass rates have more to do with the quality of their students than from the quality of their school. If we took all of stanford's 1l's and put them at concord, I believe you'd see about a ninety percent pass rate for that class.
I've noticed that all unaccredited schools in california have an absolute DISMAL pass rate. Beware.
These statistics are hard to ignore and I believe it's just a matter of time before online schools start receiving more recongnition.
