A certified midwife (CM) is a healthcare provider who has completed a graduate-level midwifery education program and passed a national certification exam, but unlike a certified nurse-midwife (CNM), does not hold a registered nursing license. CMs receive the same clinical training and take the same board exam as CNMs. The key difference is their educational path: they entered midwifery through a graduate program rather than through nursing school first.
How CMs Differ From CNMs
The distinction between a certified midwife and a certified nurse-midwife comes down to one thing: nursing licensure. A CNM is a registered nurse who then completed a graduate midwifery program. A CM completed that same graduate midwifery program and passed the same national certification exam, but came from a non-nursing background. Many CMs have undergraduate degrees in biology, public health, or other health sciences before entering midwifery training.
Both credentials are awarded by the American Midwifery Certification Board (AMCB), and both require graduation from a program accredited by the Accreditation Commission for Midwifery Education (ACME). The certification exam is identical: 175 multiple-choice questions with a four-hour time limit. Candidates get up to four attempts within 24 months of completing their program. If they don’t pass within that window, they must complete another accredited program before trying again.
In practical terms, CMs and CNMs provide the same care. The program director must attest that each graduate is performing at the level of a “safe, beginning practitioner” before they can sit for the exam, regardless of which track they followed.
What CMs Are Trained to Do
Certified midwives do far more than deliver babies. Their scope of practice covers reproductive and primary healthcare across the lifespan, inclusive of all gender identities and sexual orientations. This includes prenatal care, labor and birth management, postpartum support, family planning, contraception counseling and prescribing, gynecological exams, health screenings, vaccinations, and wellness checkups.
CMs are trained in the midwifery model of care, which emphasizes pregnancy and birth as normal physiological processes rather than medical events requiring routine intervention. This doesn’t mean they avoid medical tools when needed. It means they tend to use fewer interventions for low-risk pregnancies and focus heavily on education, informed consent, and continuity of care throughout the pregnancy-to-postpartum period.
Where CMs Practice
Certified midwives work in hospitals, freestanding birth centers, clinics, health departments, and private practices. Some attend home births. The setting often depends on state regulations and the individual midwife’s preference and training focus.
The CM credential is currently recognized in 12 states plus the District of Columbia: Arkansas, Colorado, Delaware, Hawaii, Maine, Maryland, Minnesota, New Jersey, New York, Oklahoma, Rhode Island, and Virginia. This is notably fewer than the states that recognize the CNM credential, which is licensed in all 50 states. If you’re considering care from a CM, your state of residence matters. In states that don’t recognize the CM credential, these providers cannot legally practice.
Prescriptive Authority
Whether a CM can prescribe medications depends entirely on state law. In states that recognize the credential, CMs typically have prescriptive authority similar to CNMs, which can include birth control, antibiotics, and other medications within their scope of practice. Some states grant full independent prescriptive authority with no physician oversight, while others require a collaborative agreement with a physician.
For CNMs specifically, states like Alaska, Arizona, Connecticut, Hawaii, Maine, Maryland, Oregon, and about 20 others grant full independent practice and prescriptive authority. The landscape for CMs mirrors this in the states where the credential is recognized, though the details vary. Checking your state’s midwifery board or health department will give you the most current picture of what a CM can prescribe where you live.
Birth Outcomes With Midwifery-Led Care
A large body of research supports the safety and effectiveness of the midwifery model. A scoping review of multiple meta-analyses found that midwife-led care is associated with higher rates of spontaneous vaginal delivery, fewer cesarean sections, and lower use of interventions like epidurals and forceps. One systematic review covering more than 1.4 million pregnancies found that midwife-led care was linked to lower rates of medical induction and instrumental deliveries without compromising newborn safety.
Newborn outcomes are comparable or better, too. Several meta-analyses have found reduced rates of preterm birth, stillbirth, low birth weight, and NICU admissions in midwife-led care settings. Research from a high-complexity public hospital in Spain showed that outcomes in a midwifery-led unit were similar to or better than those in traditional obstetric services for both mothers and babies.
Satisfaction is another consistent finding. Women who receive continuous midwife-led care throughout pregnancy, labor, and the postpartum period report significantly greater satisfaction with their experience compared to standard obstetric care. They’re also less likely to visit the emergency department after giving birth, suggesting that the continuity of postpartum support makes a measurable difference in recovery.
CM vs. Other Types of Midwives
The U.S. has several midwifery credentials, and they’re not interchangeable. A certified professional midwife (CPM) is certified through a different organization, the North American Registry of Midwives, and follows a different educational pathway that may include apprenticeship-based training. CPMs primarily attend out-of-hospital births. A lay midwife or direct-entry midwife may have no formal certification at all, depending on the state.
CMs and CNMs sit at the top of the credentialing hierarchy in terms of formal education. Both hold graduate degrees from accredited programs and pass a nationally recognized board exam. The CM credential was created to open the midwifery profession to people with strong science and health backgrounds who hadn’t gone through nursing school, while maintaining the same clinical standards and exam rigor as the CNM pathway.
If you’re choosing a midwife for your care, the credential tells you about their training pathway. A CM or CNM has completed a graduate program with clinical rotations, passed a standardized national exam, and meets the same competency benchmarks. The practical difference for you as a patient comes down to where you live and whether your state recognizes the CM credential.
