New Directions
On 1 January 2011, the University of Sydney began implementing a major new strategy in relation to teaching and research in business and the social sciences.
Under these changes, the Discipline of Economics, the Centre for International Security Studies and the Graduate School of Government - previously all in the Faculty of Economics and Business - moved to the Faculty of Arts, which was renamed the Faculty of Arts and Social Sciences. At the same time, the Faculty of Economics and Business was renamed The University of Sydney Business School.
