The social work profession has always been involved in dealing with uncertainty and risk in the life politics of clients. However, it is not easy for young social work students to translate this philosophical disposition into their real life practice with clients. In spring 2003, when the SARS epidemic broke out in Hong Kong, a group of social work students from the Chinese University of Hong Kong were doing their fieldwork practicum. Suddenly confronted by a collective sense of risk in their role as social workers, the students went through a period of unrest, as performing their helping duties brought with it a simultaneous exposure to personal risk. This paper is based on four focus group interviews with these social work students, to understand how they processed their experience of risk during their exposure to the SARS crisis, and how they connected the experience to their social work practice with clients. It is found that the predicament arising from the exposure to personal risk brought about by the SARS crisis during the students' field placement engendered the reflective process that enabled a renewed and personalized meaning of professionalism. The results provide a basis for reflection among social work educators on the role of risk in the training of prospective social workers, and on how social work education can better prepare students for practice in a high-risk environment.
