Social work is defined as a practice-based profession that promotes social change, social cohesion, and empowerment. It is not the same as charity work or other benevolent actions without systematic methods. To be a profession, an occupation must have a specialized body of knowledge, training requirements, professional ethics codes, and recognition as a dignified vocation that benefits society. Social work qualifies as a profession according to these criteria by having a distinct knowledge base, education and licensing standards, professional organizations, and role in solving social problems and improving lives in a systematic way.
