Such complaints procedures should: (a) be neither too prescriptive nor too restrictive in categorising what constitutes a complaint; (b) encompass a wide variety of channels through which complaints by or relating to looked after children may be made or referred to the Children's Complaints Officer including teachers, doctors, nurses, police officers and elected members as well as residential care staff and social workers; (c) ensure that any person who is the subject of complaint will not be involved in the handling of the complaint.
