The LCSW exam, formally known as the ASWB Clinical exam, is a standardized licensing examination administered by the Association of Social Work Boards (ASWB). It is required in all 50 U.S. states, the District of Columbia, the U.S. Virgin Islands, and several Canadian provinces for social workers seeking clinical-level licensure. Passing this exam is the final step before you can practice independently as a Licensed Clinical Social Worker.
