Administration is the function of leadership at the highest level of an organisation. The duties of the chief executive is to establish and formulate policies that facilitate the administration towards achieving the objectives of the organisation. The success and failure of an organisation depends largely on it. The widely acknowledged successes of the Department of music, University of Nigeria, Nsukka (UNN) hereafter Nsukka Music School (NMS) is largely due to the administrative policies that were established by the founding head of Department, Dr. Marylyn Edna Smith (later Edet). This paper interrogates the administrative policies of the NMS and their effects, and consequences as catalyst of growth and development or otherwise through the years. Data for the study were obtained from participant observation of the authors as a student in NMS from 1977 to 1982, interview of alumni and study of published articles and official files in the NMS. The technique of historical reconstruction was used in sieving the facts from the documents and assembled. The administrative policies were providing and maintaining musical instruments for staff and students, admitting students based on available resources, provision of a music building and instituting performance as community service. It is recommended that all DsM in Nigeria should establish administrative policies that enhance achieving its objectives. Administrative policies facilitated the achievements of the NMS.
