Two primary, interdependent goals of the NSW Higher School Certificate Aboriginal Studies course are enhancing Indigenous students’ self-concepts and educational outcome. It was considered that these would lead to increased Indigenous student participation and retention to Year 12. Yet recently there has been a decline in enrolments. Despite the introduction of Aboriginal Studies over a decade ago, no rigorous research has been undertaken to determine the impact of the course or the extent to which the aims of the course have been achieved. Research in Aboriginal Education has identified that Indigenous students are still not achieving at the same level as their non-Indigenous counterparts. However, the majority of studies to date have been theoretical and descriptive in nature. The primary purpose of the present investigation was to address some of the above issues by elucidating the (a) factors that influence Indigenous students’ decisions to participate in the HSC Aboriginal Studies course; (b) impact of the course on Indigenous students’ self-concepts and educational outcomes; and (c) strengths and limitations of the course. The research was undertaken in three NSW Department of Education and Training secondary schools, located in rural, north coast, and south coast areas. Results indicated that Indigenous students choose Aboriginal Studies based on their need to understand more about their own culture. There were also clear educational benefits in that Aboriginal Studies was considered to be a motivational factor that encouraged attendance at school and enhanced their academic self concept. Both staff and students suggested that the academic rigour of the Aboriginal Studies course contributed to declining enrolments. Overall the findings suggest that whilst the current course has some limitations, there are also many strengths; this implies there is a need to continue to refine the course to meet the needs of Indigenous students
