 Every service has a model, i.e., an overarching schema or framework according to which it is organized, shaped, and enacted, though not necessarily consciously so.There are many different service models.Some of the more familiar ones are the medical model, the social casework model, the correctional model, the religious reform model, the military/disciplinary model, the developmental model, and others (Wolfensberger, 2013, p. 145).
