A full suite of Masters programmes exist today and this began in 1976 when the MSc (Mgmt) degree in Management Practice for practicing senior executives was launched, with a curriculum based on action research principles. The School is part of the Faculty of Arts, Humanities and Social Sciences of Trinity College.[7]
