Until 1990, there was no independent college for the sciences. Before then, there had been three colleges: the College of Engineering, the College of Engineering, and COSALS, the College of Sciences and Liberal arts. As part of his restructuring plan, John Patrick Crecine reorganized the institute; he split COSALS into the College of Sciences and combined the liberal arts and management programs into the Ivan Allen College of Management and Liberal Arts. The latter would be split by G. Wayne Clough in 1998.
