About 60 percent of the world uses some version of civil law; about 40 percent relies on a form of common law. Among the 193 law schools in the nation accredited by the ABA, only LSU Law gives each of its students extensive study in each and a degree in each to prove it. LSU Law Center's curriculum requires six semesters.  An optional summer school is also available. Many students choose to spend summers studying in LSU Law's program in Lyon, France. Because of the constant presence of two law systems, a comparative environment and an international flavor characterize the campus.
