The American Bar Association is considering modifying law school accreditation standards to emphasize student learning outcomes over "input" measures, such as student/faculty ratio and facilities. Some law school deans are expressing concerns over the proposed changes. "There's the worry that this will create a lot more cost for schools and the concern over how open-ended the requirements will be. Will the ABA make us jump through too many hoops?" said Northwestern University School of Law Dean David Van Zandt.
