Founded in May 1991 with 94 charter members, the Institute grew to nearly 150 members in its first year. Currently, the USM-ILR has a membership of over 400. The Institute is an all-volunteer program. Its Executive Board and Standing Committees enable members to participate fully in the organization and direction of the Institute. Officers are elected to serve one year.
Present members come from a wide range of experiences and backgrounds.
Each year, the Institute conducts a number of interesting and informative classes at the suggestion of its members. The Institute's year parallels the academic year of the University. Each academic year, members participate in four terms of five weeks each. These terms usually begin in September, November, February, and April. Regular classes are held on Tuesdays and Thursdays.
