A significant proportion of the counselling that people receive takes place within informal, situated encounters between service users and practitioners in fields such as nursing, medicine, teaching and social work. However, almost all of the research that has been carried out into the process and outcomes of counselling consists of studies of formal, contracted counselling and psychotherapy based in therapy clinics and offices. The competent and effective delivery of counselling that is embedded in a primary professional role, such as that of nurse, teacher or social worker, presents considerable challenges for practitioners. Research evidence around the process and outcomes of embedded counselling represents a valuable resource that has the potential to enhance the quality of counselling conversations enacted by practitioners in health, education, social work and other professions. An overview is provided of different types of research that has been carried out into informal and embedded counselling, and of the main themes that have emerged from these studies. Suggestions are made for the further development of this field.In 1945, Virgina Axline and Carl Rogers published an account of the counselling role undertaken by a teacher, over a period of several months, in response to the emotional and social needs of a disabled six-year-old boy who was a member of a class of 36 children for whom she was responsible (Axline & Rogers, 1945). This descriptive case study illustrated the ways in which this teacher was able to make use of counselling skills, behavioural interventions and consultation with other professionals, to play a key role in the recovery of a seriously troubled young person, mainly through a series of brief, 15 min listening conversations. It is hard to find other, more recent, case examples of this kind of work.In general, the field of counselling and counselling psychology has moved in the direction of becoming a discrete area of specialised professional activity, in which psychological assistance is provided by therapists in offices, rather than teachers in classrooms. Nevertheless, alongside the development and expansion of counselling and other psychotherapeutic interventions as standalone professional activities, individuals with problems in living continued to turn to trusted members of their community, such as
