In recent years, teacher participation in school decision making has become an important topic for discussion in the field of early childhood education in Hong Kong. The purpose of this article is to discuss the theoretical significance, difficulties and issues of greater teacher participation in curriculum and pedagogical decision making in local preschools. It begins by setting out the key concepts relating to teacher participation in the process of school decision making. This is followed by a contextual analysis of the recent development of the field as the background for discussion. The third section re-examines Alutto and Belasco's typology for participatory decision making in order to outline the analytical framework of this article. Based on that framework, the fourth section examines the decision-making process of actual and desired teacher participation in the local context and discusses the factors that foster the movement towards the ideal condition of participation in decision making. It is argued that the leadership of preschool heads is cardinal in creating structures and promoting school culture for the increase of both actual and desired teacher participation in curriculum and pedagogical decision making. The possibilities and challenges of supporting and sustaining teachers in their engagement in curriculum leadership are discussed. (Contains 1 figure and 1 note.)
