The article reviews a series of normative frameworks based on which the process of supervision of social services in countries such as Singapore, New Zeeland, Australia, Canada, USA, Great Britain and Romania. By comparatively analyzing these frameworks, we noticed that generally, there are two models formulated -the first one which regards the supervisor as a professional with experiece in social work, and the other model sees supervision as a distinct profession with transdisciplinary nature, but with access limited by the need for an initial training and previous experience in the field of social work.
