In recent years there has been an increasing demand for teachers to develop the international knowledge and skills necessary to help promote their students' global perspectives. The Hong Kong Special Administrative Region Government has seized the initiative to provide mandatory overseas immersion programmes for pre-service English teachers to enhance their language proficiency and cultural understanding. This study involved a group of Hong Kong English language student teachers who joined a six-week immersion programme in Auckland. The aim of the present investigation was to address our dearth of knowledge as to the impact of such a programme on student teachers, and the benefits that they could derive from it. Several obstacles that might hinder maximal benefits were also identified. (Contains 2 tables.)
