The research articles presented in this portfolio originate from questions and concerns about the organization, leadership and practices of government secondary schools in NSW. There are presently 395 high schools and 66 central schools providing secondary education in government schools (DET, 2004 Directory, p.55). Of these high schools, 98 are specialised in some way – selective, performing arts, sports, technology, senior and multi campus (Vinson, 2002, p. 126). Over one quarter of schools are now specialised in some way, leaving just under 300 comprehensive high schools. Of these, 30 are single sex. The Department of Education and Training in NSW now says that it does not offer a system of comprehensive high schools, but a comprehensive system of high schools (Vinson, 2002, p.127). The specific focus of the research is to examine how NSW government secondary schools came to be where they are today. Change in secondary schools from both the systemic and school level is examined. The issue of the selection of a school by parents and students is also considered. And finally, development of an initial learning culture in a new high school was also a focus for research / Doctor of Education (D. Ed.)
