Midwife Credentials Matrix: CNM vs CM vs CPM
The title “midwife” covers diverse training paths, certifying bodies, and legal scopes of practice. In the United States, Certified Nurse-Midwives (CNMs) represent the gold standard for graduate-level hospital maternity care. Compare credentials below before choosing your birth team.

The CNM Educational & Clinical Pipeline
Becoming a Certified Nurse-Midwife is one of the most rigorous clinical trajectories in nursing and maternal health. It requires minimum 6 to 8 years of combined higher education and acute clinical rotations:
- Bachelor of Science in Nursing (BSN): 4 years of accredited university study in human anatomy, physiology, pharmacology, microbiology, and acute-care nursing.
- Registered Nurse (RN) Licensure: Passing the national NCLEX-RN exam and completing clinical bedside rotations, typically in labor & delivery, postpartum, or emergency care.
- ACME-Accredited Graduate Program: 2 to 3 years of rigorous graduate study culminating in a Master of Science in Nursing (MSN) or Doctor of Nursing Practice (DNP) in Midwifery. Curriculum covers embryology, advanced pharmacology, perinatal diagnostics, suturing, and thousands of hours of supervised intrapartum and well-woman clinical encounters.
- AMCB National Board Certification: Passing the comprehensive national examination administered by the American Midwifery Certification Board (AMCB).
- State APRN Licensure & Hospital Credentialing: Applying for Advanced Practice Registered Nurse (APRN) state licensure, obtaining state and federal DEA prescriptive registrations, and completing hospital medical staff credentialing.

State-by-State Practice Autonomy
Under the consensus model of the National Council of State Boards of Nursing (NCSBN), nurse-midwives should practice to the full extent of their education without mandatory supervisory contracts. State regulatory environments fall into three primary tiers:
States like Arizona, Colorado, Washington, and New York grant full independent licensure. CNMs evaluate patients, order tests, prescribe, and admit without mandatory physician supervision.
States requiring a collaborative agreement with a physician for specific elements, such as prescriptive scope or hospital admitting protocols.
States requiring continuous career-long physician supervision or delegation agreements to practice or write prescriptions.
Credentialing FAQs
What is the difference between a CNM and a CPM?↓
A Certified Nurse-Midwife (CNM) is an Advanced Practice Registered Nurse with a Master's or Doctoral degree who practices primarily in hospitals, holds full prescriptive authority in all 50 states, and can order epidurals and collaborate directly with OB/GYN surgeons. A Certified Professional Midwife (CPM) is trained exclusively in out-of-hospital birth (home and freestanding birth centers), is certified through NARM without requiring a nursing or graduate degree, and does not have hospital admitting privileges or epidural access.
Can Certified Midwives (CMs) practice in hospitals?↓
Yes. Certified Midwives (CMs) complete the identical graduate midwifery curriculum and take the exact same AMCB national certification exam as CNMs. The difference is their background is health/science rather than nursing. Where state laws license CMs (such as New York, New Jersey, and Maryland), they practice in hospitals with admitting privileges and prescriptive scope.
How do I verify a nurse-midwife's board certification?↓
You can verify that a nurse-midwife holds active national certification through the American Midwifery Certification Board (AMCB) online registry at amcbmidwife.org, as well as through your state's Board of Nursing APRN license verification portal.
Do all 50 states allow CNMs to prescribe medication?↓
Yes. Certified Nurse-Midwives possess legal prescriptive authority across all 50 states and the District of Columbia. In over 30 states and territories, CNMs practice and prescribe completely autonomously without requiring a physician supervisory agreement.
