Competent behavioural change intervention can be learned, practised and developed. Therefore, the teaching and assessment of this ability should be within the scope of both the undergraduate and post-graduate curriculum. Assessment should target knowledge base and skills in the areas of counselling, communication and behaviour. Assessment of the knowledge base should ideally be conducted in a comprehensive, multidisciplinary, centrally based manner in the pre-clinical curriculum. Assessment of skills in the areas of communication, counselling and behaviour change is a wider aim that should be integral throughout the curriculum. In continuing education (CE) environments, an initial 'screening' assessment would help educators to adjust the course to the participants' background and needs. Furthermore, three major assessment schemes are proposed: (1) assessment of knowledge and skills, (2) evaluation of the whole course by the participants, and (3) assessment of the implementation process, four to six months after completion.
