The Center for Computer-Assisted Legal Instruction, also known as CALI, is a 501(c)(3) non-profit consortium of mostly US law schools that conducts applied research and development in the area of computer-mediated legal education. The organization is best known in law schools for CALI Lessons, online interactive tutorials in legal subjects, and CALI Excellence for the Future Awards (CALI Awards), given to the highest scorer in a law school course at many CALI member law schools. Nearly every US law school is a member of CALI. CALI was incorporated in 1982 in the state of Minnesota by the University of Minnesota Law School and Harvard Law School.
