A new paradigm for public management, called "New Public Management", has emerged since the 1980s that is formed to confront at present problems. This model is originated from the fusion of economic theories and private sector management techniques. The most relief particulars of this model are decreasing government size, the decentralization of management authority, the emphasis on efficiency, effectiveness and economy. This paper examines how New Public Management (NPM) impacts on fulfilling different aspects of accountability in the public sector. In the Traditional Approach of Accountability, politicians and civil servants are liable to elected authorities but in this approach also, they should be liable to people. Therefore, in NPM there is a shift in accountability from the political to the managerial sphere and from input and processes to output and outcomes. The result shows under this approach, operational and managerial accountability fulfill but are not considered political and financial aspects of accountability.
