In the US licences social workers (LCSWs) are qualified to do psychotherapy just like clinical psychologists. marriage and family therapists (MFTs) and professional counselors (LPCCs). There is no difference in their training in terms of how to conduct psychotherapy in private settings. There are differences in terms of what kind of places they normally get employed at. Social workers who don't have private practices often work for nursing homes, government agencies and others who assist the under served population. They could be licensed or unlicensed. Those who work for an agency usually don't conduct psychotherapy.
