National Law Journal:  Two Law Schools Offer a Money-Back Guarantee — With Strings Attached, by Karen Sloan:

Can't pass the bar exam? Here's a $10,000 refund. 

Two law
schools are experimenting with refund programs for graduates who don't
pass the bar examination after two tries, provided they complete a
rigorous set of bar preparation courses beforehand.

Florida
Coastal School of Law is offering the same refund to students dismissed
for academic reasons following their 1L year, plus $2,000 to those who
fail to secure a externship, clerkship, clinical experiences or other
substantive legal work while in school.

The Charlotte School of
Law has launched its own pilot program offering $10,000 to graduates
tripped up more than once by the bar exam. Both are for-profit law
schools operated by InfiLaw Inc., which also owns the Phoenix School of
Law.

The idea behind the Assured Outcomes Partnership, as the
programs have been dubbed, is to assure students and prospective
applicants that their instructors will do all they can to help them
succeed both academically and in their careers.
