Since the early part of this century primary education has existed within a laissez-faire structure. The professional autonomy of teachers has, up to now, never been seriously threatened. The independence of Individual schools is a feature of the English education system. However, because education is a fundamental part of society it is inevitable that differing aspects of society affect education both directly and indirectly. The main area of interest examined in this study is the tension between the numerous factors affecting head teachers and the laissez-faire framework within which the head teacher has to work. This area of interest is examined by using two strategies. First, by using an historical perspective the study will evaluate the effects of society on primary schools. The investigation will assess how external influences and historical events have affected primary head teachers. Second, an Investigation into the internal life of primary schools - factors affecting head teachers on a day-to-day basis, the focus will be upon the interaction of parties within the institionalized setting. The role of the head teacher as a leader, educational manager and administrator will be explored in the context of the present major redefinition of education, which has at its heart the dismantling of the laissez-faire tradition.* Author's note. The radical and ceaseless nature of the redefinition of education following the 'Great Debate* of the mid seventies has created severe problems for the writer. Certain arguments and comments have been 'overtaken* by the march of history. The summer of 1986 is the finishing point of this investigation and the reader will need to bear this in mind.
