Careers in social work and human services are both motivated by a desire to improve the lives of people in need. They can take place in similar settings, including home health agencies, hospitals, and health clinics. Nevertheless, there are differences. One of the biggest differences between social work and human services jobs is licensure. To be in social work practice, you need a license; to work in human and social services, you do not. In addition, time to completion tends to be longer for social work programs due to a larger credit requirement. Career paths may also differ: Social workers generally work more directly with clients, while human and social services professionals tend to work with organizations to direct needed resources to vulnerable, underserved populations.
