Abstract
This paper tried to understand why caring people want to be "professionals" through analysing the interaction with their clients. 'Caring' requires caring people to take the unlimited responsibility for their clients as an ideal type. But in practice, caring people have to specify their roles and functions, because they cannot have full control over the clients. Then they often wonder whether the specialization is appropriate for the clients. As they cannot depend on client's validation, they need the institutionalization of expertise to get evaluation. Through such consideration, we can start to reconsider the concept of caring professionals which differs from that of exclusive 'autonomy' model.
