The amalgamation of Broadland House C.E.G.G.S. and the Launceston Church Grammar School was announced, as a fait accompli, in April 1982. The merger was to be in two stages; the separate operation of both schools under the one Headmaster from June 1982 and the completely merged schools from the beginning of 1983. Both Broadland House and the Launceston Grammar claim to be the oldest continuing schools in Australia, having been founded in 1845 and 1846 respectively. The fact that many families had been involved with either or both schools for four or five generations led to period of bitter conflict and resistance to change, which was largely overcome by the end of the first year of operation. Diminishing enrolments at both schools had been brought about largely through the rural recession in Tasmania during the 1960's, together with the provision of better school facilities and roads in the rural areas of Tasmania. The Launceston Church Grammar had become co-educational in 1972, largely as a means of survival. Previous approaches to Broadland House, by the Grammar School, to consider amalgamation had been rejected. This study endeavours to determine the strategies which led to the almost total acceptance of the amalgamation between the Broadland House Church of England Girls Grammar School and the Launceston Church Grammar School, and to explain those strategies through reference to the literature on the management of change. This involved rationalising resources, setting up new academic courses, providing physical facilities, considering the traditions of both schools, the gaining of financial, support and of developing acceptance of the change within the school community and within the community at large. The study follows the period covering the eight months of preparation prior to the amalgamation together with its first 5 years of operation, during which time the School has grown considerably and enjoys wide confidence and support. As amalgamations are occurring more regularly across the nation, it is hoped that the lessons learned through this educational innovation will be of benefit to others.
