The Credentials CNM and CM

Certified nurse-midwives are registered nurses who have graduated from a nurse-midwifery education program accredited by the Accreditation Commission for Midwifery Education (ACME) (formerly the American College of Nurse-Midwives (ACNM) Division of Accreditation (DOA)) and have passed a national certification examination to receive the professional designation of certified nurse-midwife. Nurse-midwives have been practicing in the U.S. 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.
