New York has made a couple of changes that have the potential to affect elite law schools (where, presumably, a substantial portion of the students want to maintain the option of taking the NY bar). One is the requirement for a stand-alone PR course. I have over 30 PR students this semester who are foreign LLM students and many of them have told me that they need to maintain their NY eligibility. The other is NY's new 50 hour pro bono requirement for people sitting for the bar exam. Reuters and Above the Law are reporting that the loose standards for what counts as pro bono may mean that the requirement will have little impact on many students and little benefit to the under-represented poor.
If the New York, California, Texas, Florida, and Illinois bars had a mind to reform legal education, they might be able to effectively regulate most law schools. I don't imagine that they'd really want to take on an overhaul of legal education, but they might seek some significant changes. For example, California is considering adding a requirement for practical skills training. No doubt, the law schools will oppose many of these measures. (At The Faculty Lounge, Dan Filler has a post on the possibility that states will get more involved in law school regulation.)
