This paper investigates the views of immersion teachers in Hong Kong and Xi'an towards the immersion curriculum they are teaching. Teachers are important stakeholders in any curriculum implementation and their views are significant in both evaluating progress and determining future directions. The teachers' views were gathered from questionnaires and interviews. Topics include their understanding of the objectives of immersion education, their preparedness for their roles as immersion teachers, the main challenges in immersion teaching they identify and the support they receive from their schools. The responses are discussed to identify areas of concern which may be future priorities for professional development.
