The International Federation of Social Workers and the International Association of Schools of Social Work define social work as “a practice-based profession and an academic discipline that promotes social change and development, social cohesion, and the empowerment and liberation of people.” Social work majors take classes on topics such as social welfare policy, case work planning, family services, employment services, and counseling. Social workers can work for international nonprofits such as the United Nations or the International Rescue Committee.
