In the United States, MSW degrees must be received from a graduate school that has been approved by the Council on Social Work Education (CSWE) should the graduate seek future licensure. The MSW typically requires two years of full-time graduate study in combination with two years (900–1200 cumulative hours) of internship, also referred to as field practicum, education, or experience. While some students obtain a Bachelor of Social Work (BSW) before pursuing a master's, most MSW programs accept applicants with undergraduate degrees in a broad range of liberal arts fields. Some MSW programs provide BSW graduates with an advanced standing option, allowing them to complete an MSW in a shorter period of time (typically 1 year).
