In the new millennium the Department once again expanded rapidly. Social Policy teaching has developed strongly with the successful graduate degrees in Comparative Social Policy attracting an international entry of about thirty graduate students a year, many of whom go on to doctoral studies. The successful MSc in Applied Social Studies social work training course, which the Department ran for many years, was phased out and the final group graduated in Trinity Term 2004. In 2003 a new MSc course in Evidence-Based Social Work was successfully launched with an initial international intake of 20 students.
George Smith became Head of Department in 2005, followed by Peter Kemp in 2007. In 2010 Barnett House became the Department of Social Policy and Intervention to reflect its evolved teaching and research focus. Martin Seeleib-Kaiser was appointed Head of Department in 2011 and Rebecca Surrender in 2015. Since October 2017 Bernhard Ebbinghaus is Head of Department.
Research has also expanded steadily since the late 1990s. At any one time there are 25 or so separate funded research projects underway in the Department, with more than 20 research staff and an annual turnover of approximately £1.5m. Funds come from research councils, charitable foundations, local authorities and government departments and increasingly from overseas governments or agencies. Since the late 1990s research in the Department has included some major national and international studies that have made a very substantial impact on national and local resource allocation, policy formation, policy implementation and evaluation.
In 2014, the Department celebrated its centenary. Now more than a century after its foundation, Barnett House continues to uphold the tradition of providing high quality graduate and research training, closely linked with the importance of social enquiry and social evaluation, driven by a concern for better informed social policy, social intervention and social reform. Our work is now organised into two research centres: Centre for Evidence-Based Intervention and Oxford Institute of Social Policy.
