What Is CM Certification?
The Certified Midwife (CM) credential is a national certification awarded by the American Midwifery Certification Board (AMCB) to graduates of accredited midwifery programs who do not hold a registered nurse license. The CM designation and the Certified Nurse-Midwife (CNM) designation both come from the same national certification examination - the difference is the educational pathway a candidate took to get there, not the content of the test itself. If you're just getting oriented, our companion pieces on What Is CM?, CM Meaning, and What Does CM Stand For? walk through the terminology in more depth.
This article focuses specifically on what a CM candidate needs to know: who administers the exam, what it costs, how it's structured, and which content areas carry the most weight. For a broader look at the credential itself, see What Is A CM? and What Does CM Mean?.
Who Issues the CM Credential and How the Exam Works
AMCB owns and administers the certification program, but the actual computer-based exam is delivered through PSI testing centers. Candidates schedule their appointment through PSI once AMCB confirms eligibility. This split - AMCB handling eligibility and credentialing, PSI handling test-day logistics - trips up some first-time candidates who expect one organization to manage the entire process.
Because the CM and CNM pathways share the identical national exam, the domain content, question format, and passing standard are the same regardless of which credential you're pursuing. What differs is the eligibility route: CM candidates complete a graduate degree or institutional graduate-degree requirements within an ACME-accredited or pre-accredited midwifery program, without an RN license as a prerequisite.
Eligibility Requirements for the CM Pathway
Before you can even schedule the exam, AMCB requires three things to be in place:
- Completion of a graduate degree - or the graduate-degree requirements set by an institution - through an ACME-accredited or pre-accredited midwifery program.
- Program-director verification confirming you completed the required coursework and clinical components.
- An attestation of safe beginning-practitioner performance, signed off by your program.
These pieces get submitted to AMCB, which then clears you to register for the PSI-administered exam. For the full breakdown of documentation, deadlines, and common eligibility snags, read CM Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Key Takeaway
Start your eligibility paperwork with your program director well before graduation - verification and attestation steps can take longer than candidates expect, and you can't schedule with PSI until AMCB has everything on file.
Exam Format, Fees, and Scoring
The CM exam consists of 175 four-option multiple-choice questions, some of which are unidentified, scattered pretest items that don't count toward your score but that you can't distinguish from scored questions during the test. You get four hours to finish. Breaks are allowed, but the clock keeps running, so plan your pacing accordingly.
Key mechanics to know before test day:
- Initial exam fee: $425
- Retake fee: $350 per attempt
- Passing score: 75 on AMCB's 0-100 scaled-score system
- Calculators: Not permitted
- Results: Issued at the testing center immediately after you finish
For a complete cost breakdown including how fees stack up across attempts, see CM Certification Cost 2026: Complete Pricing Breakdown. If you want a deeper explanation of what a scaled score of 75 actually means in practice, CM Passing Score 2026: Exactly What You Need to Pass covers it in detail.
| Exam Element | Detail |
|---|---|
| Administering body | AMCB (exam delivered via PSI) |
| Question count | 175 four-option multiple-choice items |
| Time allowed | 4 hours (breaks permitted, timer continues) |
| Passing score | 75 on 0-100 scaled score |
| Initial fee | $425 |
| Retake fee | $350 |
AMCB's official 2025 combined CNM/CM pass rates were 74.5% for first-time candidates, 55.5% for repeat candidates, and 69.8% overall. Those numbers illustrate why first-attempt preparation matters more than banking on a retake.

The Six Content Domains
Since January 1, 2023, the exam's content weighting has been based on the 2022 Task Analysis. There are six domains, and two of them tie for the largest share of the test.
Domain 1: Antepartum (21%)
Covers assessment and management of pregnancy from confirmation through the onset of labor.
- Prenatal screening and diagnostic decision-making
- Risk identification and appropriate referral thresholds
- Management of common and complicated antepartum conditions
Domain 2: Intrapartum (21%)
Covers labor and birth management, tied with Antepartum as the exam's heaviest domain.
- Fetal heart rate interpretation and labor progress assessment
- Second and third stage management
- Recognition of emergent intrapartum complications
Domain 3: Postpartum (18%)
Covers maternal recovery and complication management after birth.
- Physical and psychosocial postpartum assessment
- Lactation support and complications
- Postpartum hemorrhage and infection recognition
Domain 4: Newborn (10%)
The smallest domain but still tests core newborn assessment competencies.
- Newborn transition and initial assessment
- Screening protocols and referral criteria
- Recognition of common newborn complications
Domain 5: Well Woman/Gyn (19%)
Covers gynecologic and preventive care across the lifespan, the second-largest domain.
- Contraceptive counseling and management
- Routine gynecologic screening and preventive care
- Management of common gynecologic conditions
Domain 6: Women's Health/Primary Care (11%)
Covers primary care topics relevant to midwifery-scope practice.
- Common primary care conditions within scope
- Health promotion and chronic disease screening
- Coordination and referral for conditions outside scope

Building a Domain-Weighted Study Plan
Because Antepartum and Intrapartum together account for 42% of the exam, your study calendar should reflect that weighting rather than splitting time evenly across all six domains. A practical way to allocate weeks: give the two heaviest domains roughly double the time you give Newborn, the lightest domain, and use short, focused review blocks rather than marathon sessions so retention holds up over the full four-hour test.
Antepartum + Intrapartum
- Work through prenatal risk assessment and labor management scenarios
- Practice fetal heart rate strip interpretation daily
Well Woman/Gyn + Postpartum
- Review contraceptive counseling frameworks and preventive screening intervals
- Drill postpartum hemorrhage recognition and response
Women's Health/Primary Care + Newborn
- Cover primary care referral thresholds within midwifery scope
- Finish with newborn transition and screening protocols
Full-Length Practice and Timing
- Take full 175-question timed practice runs with no calculator
- Review missed items by domain to target remaining gaps
Full-length timed practice matters because the exam gives you four hours with a continuously running clock even during breaks - you need to know your pacing well before test day. Our CM Study Guide 2026: How to Pass on Your First Attempt expands on this timeline with specific practice recommendations, and you can run through timed questions modeled on the real exam format at our CM practice test platform.
Retake Rules and Timelines
Candidates get four attempts within 24 months of program completion. If your first attempt doesn't result in a pass, the first retake requires a 30-day waiting period; any later retakes require 90 days between attempts. Each retake costs $350, separate from the $425 initial exam fee.
Because the repeat-candidate pass rate is meaningfully lower than the first-attempt rate, treat your first sitting as the one to prepare for most seriously rather than assuming a retake will be a quick fix. Understanding the exam's format and pacing in detail before you sit for it the first time is the single most controllable factor.

After You Pass: Maintenance and Career Paths
Once you pass, your certification runs through the fifth year after issue. Renewal happens either through completing three maintenance modules plus 20 approved contact hours and paying annual fees, or by reexamination in years four or five. Deciding early which renewal path fits your practice setting and continuing-education preferences avoids a scramble as your five-year window closes.
CM-credentialed practitioners work across a range of settings, from hospital-based birth centers to outpatient women's health clinics, depending on state scope-of-practice regulations.
