Associate in Science

The associate degree program in Diagnostic Medical Sonography (DMS) prepares students for employment as entry-level sonographers in hospitals, outpatient clinics, and medical offices. The program provides individuals with the academic and technical skills necessary to perform abdominal, obstetrical and gynecological, and vascular sonography procedures. Upon completion of the program, students will be eligible to apply to take the national registry examination from the American Registry of Radiologic Technologists (ARRT) and/or the American Registry of Diagnostic Medical Sonographers (ARDMS). The program requires 24 months of full-time study. Students are assigned to clinical practicum at affiliates throughout the state of Connecticut.
