The British Psychological Society is the scientific society and professional body for psychologists, incorporated by Royal Charter in 1965. The Society is a learned and professional body controlled by the Royal Charter. This means that their primary duty is to preserve and nurture the discipline on behalf of the nation. Their main objective is to advance and diffuse knowledge of psychology.

Since 1987 the Society has established and maintained the Register of Chartered Psychologists, which has stringent entry requirements. Only those on the Register are allowed to use the title 'Chartered Psychologist' or the abbreviation 'C.Psychol'.
