A CNM, or Certified Nurse-Midwife, is an advanced practice registered nurse who specializes in pregnancy, childbirth, postpartum care, and general reproductive health. CNMs hold a minimum of a master’s degree in nurse-midwifery and are licensed to practice in all 50 U.S. states. They can deliver babies, prescribe medications, order lab tests, and provide primary gynecological care, making them one of the most versatile providers in women’s health.
What a CNM Actually Does
Certified Nurse-Midwives provide care that spans far beyond labor and delivery. Their scope includes prenatal checkups, managing high-risk and low-risk pregnancies, attending births in hospitals, birth centers, or homes, and handling postpartum recovery. Outside of pregnancy, CNMs perform annual exams, prescribe birth control, treat infections, manage menopause symptoms, and counsel patients on reproductive planning.
CNMs are trained in both nursing and midwifery, which gives them a dual clinical foundation. They can work in hospitals alongside obstetricians, run independent practices in states that allow it, or staff community health clinics. Many CNMs serve as a patient’s primary women’s health provider for years, not just during a single pregnancy.
How CNMs Differ From Other Midwives
The title “midwife” covers several distinct credentials in the U.S., and the differences matter. A CNM starts as a registered nurse, then completes a graduate-level midwifery program accredited by the Accreditation Commission for Midwifery Education. This nursing background is what separates CNMs from other midwife types and is the reason they’re classified as advanced practice registered nurses (APRNs).
A Certified Midwife (CM) follows a similar graduate-level program but does not hold a nursing degree. CMs are currently recognized in only a handful of states, including New York, New Jersey, Delaware, Hawaii, Maine, Oklahoma, Rhode Island, and Virginia. A Certified Professional Midwife (CPM) takes a different path entirely. CPMs can qualify through multiple educational routes, must demonstrate out-of-hospital birth experience, and pass a separate skills evaluation and written exam. CPMs typically attend births in homes or birth centers rather than hospitals.
Because CNMs are APRNs, they generally have the broadest legal scope of practice among midwife types, including hospital privileges, prescriptive authority, and eligibility for insurance reimbursement.
Education and Certification Requirements
Becoming a CNM requires several layers of training. You first need a bachelor’s degree in nursing and an active registered nurse license. From there, you enter a graduate program in nurse-midwifery, earning either a master’s or doctoral degree from a university-affiliated program accredited by the Accreditation Commission for Midwifery Education. Clinical training during the program must align with national core competencies and takes place under the supervision of a certified CNM, CM, or another qualified advanced practice nurse.
After completing the graduate program, candidates sit for a national certification exam administered by the American Midwifery Certification Board (AMCB). The exam consists of 175 multiple-choice questions. Since January 2011, a graduate degree has been required to be eligible for the exam. Passing earns the CNM designation, which must then be maintained through ongoing certification requirements.
All told, the path from starting a nursing degree to earning CNM certification typically takes six to eight years, depending on whether you pursue a master’s or a doctoral degree and whether you work as an RN between programs.
Prescribing and Practice Authority
One of the most common questions about CNMs is whether they can prescribe medications and practice without a supervising physician. The answer depends entirely on your state.
Some states grant CNMs full independent practice and prescriptive authority, meaning they can diagnose, treat, and prescribe (including controlled substances) with no physician oversight. Alaska is one example: CNMs there may independently prescribe both standard medications and Schedule II through V controlled substances. Other states require a collaborative agreement or supervisory relationship with a physician before a CNM can prescribe. California, for instance, requires physician supervision for prescribing, while Kentucky allows full independent practice but requires a physician relationship specifically for prescriptive authority.
Several states fall somewhere in between, requiring a transition-to-practice period before a new CNM can practice or prescribe independently. The overall trend has been toward expanding CNM autonomy, but the patchwork of state laws means your experience with a CNM may look quite different depending on where you live. In states with full practice authority, a CNM can function as your sole provider for routine women’s health needs.
Where CNMs Work
CNMs practice across a wide range of settings. Hospitals remain the most common workplace, where CNMs manage labor and delivery, collaborate with obstetricians on complex cases, and provide inpatient postpartum care. Birth centers, which offer a lower-intervention environment than hospitals, are another frequent practice setting. Some CNMs attend home births, though this is less common and depends on state regulations and individual practice decisions.
Outside of birth-related care, you’ll find CNMs in outpatient clinics, private practices, federally qualified health centers, and military or Veterans Affairs facilities. In rural and underserved areas, CNMs often fill critical gaps in women’s health access, serving as the only reproductive health provider for miles.
Salary and Job Outlook
The Bureau of Labor Statistics reported a median annual wage of $128,790 for nurse-midwives as of May 2024. That places CNMs among the higher-earning nursing specialties, though compensation varies by state, practice setting, and years of experience. Urban hospitals and states with higher costs of living tend to pay more, while rural positions sometimes offset lower salaries with loan repayment programs or signing bonuses.
Job growth for nurse-midwives is projected at 11% from 2024 to 2034, which is faster than average for all occupations. Growing demand for midwifery-led care, expanded scope-of-practice laws, and a nationwide shortage of obstetric providers in rural communities are all driving this trend. For nurses weighing advanced practice specialties, midwifery offers both strong earning potential and a labor market that’s moving in a favorable direction.
