AccessLex Institute has developed this research brief to provide an overview of legal education pipeline programs in the U.S. – the channel by which we, as stakeholders in legal education, can improve access to law school. The prevalence of these programs and their components are discussed in detail. The brief also takes preliminary steps towards assessing their impact and effectiveness. The immediate goal is to provide useful information to aspiring students, their advisors, and others concerned about legal education diversity. The ultimate goals for future research are to identify components shared by the most effective and impactful pipeline programs, and to encourage other programs to adopt those best practices.
