As the faculty grew and developed so did the academic offerings, with several advanced level courses established. In 1963 the name of the Handelsdiplom degree was changed to "siviløkonom", with graduate receiving the same title. A master level programme, "høyere avdelingstudium" (HAS), was introduced in 1972 as a preparation for "siviløkonom" students wishing to continue on to doctoral studies; and in 1973 Professor Dag Coward established a master level programme for students wishing to specialise in auditing, accounting and the financial management of firms, the "høyere revisorstudium" (HRS). In 1975 the "siviløkonom" degree course was extended to a four-year programme.
