The twenty-first century is characterized by rapid change, globalization, hyper-competition, and hyper-uncertainty. Traditional models of governance and public administration are no match for the challenges of this chaotic environment. There is an urgent need to restore, both in theory and practice, public governance and administration to develop new sets of knowledge and skills that can meet the challenges posed by a age of rapid changes. The Civil Service in the UK is proud of the values, talents and effectiveness of their service. They are highly respected by foreign counterparts, whilst arousing their fierce competition. With such outstanding reputation, expectations are also high. Consequently, the government is keen to reinvigorate the concept of public service, and celebrate the contribution it makes to society. The history of civil service reform in Britain dates back to the seminal 1854 report by Sir Stafford Northcote and Sir Charles Trevelyan. It introduced competitive examinations and promotion based on merit. Between 1966 and 1968, the Fulton committee conducted a wide-ranging examination of the nature, purpose, composition and management of the civil service and made a series of recommendations which were designed to remodel the civil service and equip it to meet the challenges of the late twentieth century. The Fulton Report said that "training should be designed to prepare administrators to work in different sectors (economic/financial and social), specialists need to attain an adequate degree of administrative/managerial know-how in addition to the conventional skills attached to their function". This paper will examine the history of the British civil service training system under Tony Blair and Gordon Brown Administration. Starting from 1999, when the Centre for Management and Policy Studies began to deliver a wide range of administrative courses, and following its re-organization as the National School of Government in 2005, it is possible to draw the guidelines for mass training programmes targeting senior leaders. The analysis will highlight the importance of organizational development, and the added value represented by higher level learning and academic excellence criteria when included into government reform agenda. Even more, it will be possible to understand how advanced training can augment civil servants' capability to handle problems arousing in a rapidly changing context environment, which is the role of training institutes in building Departmental capability as well as individual skills, and how all this ends by ensuring the effectiveness of training programs in supporting public services reform and cross-cutting programmes.
