The American College of Nurse-Midwives (ACNM) is the professional association that represents certified nurse-midwives (CNMs) and certified midwives (CMs). The American College of Nurse-Midwives provides the following definitions for Certified Nurse-Midwives and Certified Midwives
Certified nurse-midwives are registered nurses who have graduated from a nurse-midwifery education program accredited by the Accreditation Commission for Midwifery Education (ACME) and have passed a national certification examination to receive the professional designation of certified nurse-midwife. Nurse-midwives have been practicing in the United States since the 1920s.
Certified midwives are individuals who have or receive a background in a health related field other than nursing and graduate from a midwifery education program accredited by ACME. Graduates of an ACME-accredited midwifery education program take the same national certification examination as CNMs but receive the professional designation of certified midwife.
The American Midwifery Certification Board (AMCB) administers the national certification examination for CNMs and CMs. CNMs are legally authorized to practice in every state in the United States and in the District of Columbia. CMs are currently legally authorized to practice in New York, New Jersey, Rhode Island, Delaware and Missouri
