- Antepartum and Intrapartum are tied as the largest domains at 21% each - prioritize them.
- The exam is 175 four-option MCQs in four hours, with unidentified pretest items mixed in.
- Passing score is 75 on AMCB's 0-100 scale - not a raw percentage of questions correct.
- Initial exam fee is $425; retakes cost $350, with a 30-day wait before the first retake.
Quick Facts Snapshot
If you only have five minutes before you walk into the testing center, this is the page to reread. The Certified Midwife (CM) credential is awarded by the American Midwifery Certification Board (AMCB) through the same national certification examination that also awards the CNM credential - the CM pathway simply serves graduates of accredited midwifery programs who do not hold an RN license. PSI administers the computer-based exam, and the content weights you'll see below have been effective since January 1, 2023, based on AMCB's 2022 Task Analysis.
| Item | Detail |
|---|---|
| Certifying body | American Midwifery Certification Board (AMCB) |
| Test administrator | PSI (computer-based testing) |
| Question count | 175 four-option multiple-choice items (includes scattered unidentified pretest questions) |
| Time allotted | 4 hours (breaks allowed, clock keeps running) |

Domain Breakdown at a Glance
The CM exam is built around six content domains, and knowing their relative weight changes how you allocate study time. Two domains are tied for the top spot, which surprises a lot of candidates who assume newborn or gynecologic content dominates.
Domain 1: Antepartum (21%)
Tied for the largest share of the exam. Covers prenatal assessment, risk screening, and management across the full pregnancy timeline.
- Gestational dating and fundal height correlation
Domain 2: Intrapartum (21%)
Also tied for the largest domain. Labor management, fetal monitoring interpretation, and delivery decision-making live here.
- Stages of labor and expected progress patterns
Domain 3: Postpartum (18%)
The third-largest domain, covering maternal recovery, complications, and immediate postpartum assessment.
- Hemorrhage recognition and early intervention
Domain 5: Well Woman/Gyn (19%)
Nearly as large as Postpartum. Screening, contraception counseling, and gynecologic conditions outside pregnancy.
- Contraceptive method counseling across the lifespan
Domain 6: Women's Health/Primary Care (11%)
Broader primary care content applied to a women's health population.
- Chronic condition management overlapping with reproductive care
Domain 4: Newborn (10%)
The smallest domain by weight but still tested in detail - immediate newborn assessment and stabilization.
- APGAR scoring and transition-to-extrauterine-life findings
For a full domain-by-domain content map with subtopics, see the CM Exam Domains 2026: Complete Guide to All 6 Content Areas guide. Since Antepartum and Intrapartum together make up 42% of the exam, they deserve roughly two out of every five hours you spend reviewing.
Exam Mechanics You Can't Forget
The format itself trips people up as much as the content does. Here's what you're actually walking into on test day:
- 175 four-option multiple-choice questions - no multi-select, no fill-in, no essay. Every item has exactly one correct answer among four choices.
- Unidentified pretest items are scattered throughout - you won't know which questions are scored and which are being field-tested, so treat every question as if it counts.
- Four hours total, and breaks are allowed - but the clock does not pause. Plan your break strategy in advance so you're not surprised mid-exam.
- Calculators are prohibited. Any dosage, gestational-age, or clinical calculation math must be done by hand or estimated using techniques you've practiced beforehand.
- Results are issued at the testing center - you'll know your outcome before you leave the building, which is a rare feature compared to many certification exams.
If you're still trying to gauge how these mechanics translate into real difficulty, How Hard Is the CM Exam? Complete Difficulty Guide 2026 breaks down the experience in more depth, and CM Pass Rate 2026: What the Data Shows walks through what the numbers mean for first-time versus repeat candidates.
Key Takeaway
Because the four-hour timer never pauses for breaks, rehearse your full exam under timed conditions at least twice before test day - not just individual practice sets.
Fees, Eligibility, and Attempt Rules
Money and eligibility logistics are easy to overlook until they become a scheduling emergency. Keep these numbers in your back pocket:
- Initial exam fee: $425
- Retake fee: $350 per attempt
- Attempt window: four attempts within 24 months of completing your midwifery program
- Retake waiting periods: 30 days before your first retake, 90 days before any subsequent retake
Eligibility itself isn't just about paying the fee. You need to complete a graduate degree or the institutional graduate-degree requirements within an ACME-accredited or pre-accredited midwifery program, secure program-director verification, and attest to safe beginning-practitioner performance. There's no RN license requirement in the CM pathway - that's the core distinction from the CNM route, even though both credentials come from the same national certification examination administered by AMCB. The full eligibility checklist, including documentation specifics, is covered in CM Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Scheduling your test date also matters more than people expect, especially around program graduation timing and the 24-month attempt window. CM Exam Dates 2026: Testing Windows, Deadlines & Scheduling lays out how to plan your testing calendar so you're not racing the clock.
Final-Week Review Schedule
A generic study calendar won't help you here - what matters is matching review intensity to domain weight in the days right before your test. This condensed timeline assumes you've already done your primary content review and are in pure reinforcement mode.
Antepartum + Intrapartum Drill
- Timed question sets focused on the two 21% domains
- Review any fetal monitoring strips you've missed repeatedly
Postpartum + Well Woman/Gyn
- Postpartum hemorrhage protocols and complication triage
- Contraceptive counseling scenarios across age groups
Newborn + Women's Health/Primary Care
- Immediate newborn assessment sequences
- Chronic disease overlap questions in the primary care domain
Full-Length Timed Simulation
- One complete 175-question, four-hour run with no calculator
- Light review only - no new content
This is the one place we'll lean on generic study methodology - everything else in this cheat sheet is CM-specific. For a full-length study plan starting from week one, not just the final stretch, see the CM Study Guide 2026: How to Pass on Your First Attempt.
Must-Know Clinical Topics by Domain
Beyond the percentages, here's what actually shows up in question form across each area:
- Antepartum: risk-factor identification, prenatal lab interpretation, gestational age assessment, and management of common pregnancy complications.
- Intrapartum: labor progress evaluation, fetal heart rate pattern interpretation, pain management options, and decision points for escalation of care.
- Postpartum: hemorrhage management, wound and incision assessment, lactation support, and psychosocial screening in the recovery period.
- Newborn: immediate transitional assessment, feeding assessment, and identification of findings requiring referral.
- Well Woman/Gyn: cervical and breast cancer screening protocols, contraceptive counseling, and management of common gynecologic complaints.
- Women's Health/Primary Care: chronic disease screening and management as it intersects with reproductive-age and midlife women's health needs.
Employers hiring Certified Midwives - birth centers, hospital-based midwifery groups, and community health practices among them - expect fluency across all six areas, not just labor and delivery.

Complete ROI Analysis 2026 ties the cost and career pieces together.
After the Exam: Scoring and Renewal
Passing is measured against a scaled score of 75 on AMCB's 0-100 system - this is not the same as answering 75% of questions correctly, since scaled scoring adjusts for item difficulty. You'll get your result at the testing center itself, so there's no waiting period for official notification.
Once you're certified, the clock starts on a five-year cycle. Certification runs through the fifth year after issue, and renewal happens one of two ways: complete three maintenance modules plus 20 approved contact hours along with annual fees, or sit for reexamination in year four or five. Neither path is inherently harder - it's a matter of which fits your continuing-education preferences and schedule.
Key Takeaway
Mark your renewal deadline the moment you pass. The five-year window feels distant on exam day but sneaks up fast once you're working full-time.
