The Institutional Index is primarily a measure of a law school's student enrollment in a given year and its annualized growth in enrollment, degrees awarded, credit hours required for graduation, and the number of deans and administrators and their ratio to students. The law school's age is also a factor. If a prospective law student is most interested in an institution's size, the categories which define the Institutional Index, may be most helpful.
