More from Michigan's site:
Michigan is 1 of the top 3 of our peer law schools in the percentage of graduates taking their first job in public interest (judicial clerkship, public interest, and government).http://www.law.umich.edu/currentstudents/PublicService/index.htm
And, towards the bottom of their FAQ for Prospective Students:
Is there any help for students who want to pursue Public Interest work?
The Public Service Office provides counseling to students who want to pursue jobs in public interest or in the public sector. The University of Michigan was recognized in 2001 as the Public Interest School of the Year by the student division of the ABA. The Debt Management Program also aids graduates who are interested in public interest and public service by helping them pay back a proportion of their loans based on their income. This is one of the strongest and most progressive programs of its kind in the country; there is no requirement that the job be of any particular kind, other than that it be law-related, which is different from most other schools' policies. Last year, about $400,000 was distributed to almost 100 people. In addition, there are student funded fellowships for students working in unpaid public interest or public sector internships; last year, more than 65 students received fellowships of $3200 each.
I don't attend U of M Law, so all I can give you is what's up on their page.
