In this chapter, we give an overview of the mathematics teacher education in Hong Kong. Against this background, the contents of the preparatory programme for pre-service and in-service mathematics teachers offered by the Faculty of Education at the University of Hong Kong are reviewed. Important stages of changes of the programme in the past decade are traced, and the content of the mathematics-related component is analyzed. Four issues on preparation of mathematics teachers are then discussed. They include: understanding of the mathematics curriculum, mastering of generic teaching skills and the teaching of specific topics, the development of basic needs for an era of information technology, and the development of teachers’ ability of self-reflection.[Copyright © 2010 Sense Publishers.
