- CM eligibility requires an ACME-accredited graduate midwifery program, not an RN license.
- Program-director verification and a beginning-practitioner attestation are mandatory before you sit for the exam.
- The exam is 175 four-option questions in four hours, administered by PSI, passing score 75.
- Candidates get four attempts within 24 months of program completion, with 30- and 90-day retake waits.
CM Requirements Overview
The Certified Midwife (CM) credential is issued by the American Midwifery Certification Board (AMCB) through the same national certification examination that also awards the CNM credential. The difference isn't the test itself - it's the pathway into it. The CM route exists specifically for graduates of accredited midwifery programs who do not hold an RN license, giving non-nursing candidates a legitimate route into certified midwifery practice. If you're still sorting out what separates this credential from similarly-named ones, What Is CM? and CM Meaning are good starting points before you dig into the requirements below.
Because CM and CNM share one exam blueprint, the requirements conversation is really two conversations: what your education pathway must look like to be eligible, and what the exam itself demands once you're cleared to sit for it. This article walks through both, plus the retake and renewal mechanics that shape your timeline.
Education & Program Prerequisites
Before you can register for the exam, you need to complete a graduate degree or meet your program's institutional graduate-degree requirements within a midwifery program that is ACME-accredited or holds pre-accreditation status. This is non-negotiable - AMCB will not process an application tied to a program outside that accreditation umbrella.
Three structural pieces make up the prerequisite chain:
- Accredited program completion: Your degree or graduate-level coursework must come from an ACME-accredited or pre-accredited midwifery program.
- Program-director verification: Your program director must formally verify that you completed the requirements, not just that you enrolled.
- Beginning-practitioner attestation: Someone with direct knowledge of your clinical performance must attest that you practice safely at the level expected of a new midwife.
None of these substitute for clinical competence - they're the paperwork trail that proves it. Skipping ahead to exam content without confirming these boxes are checked is the most common way candidates delay their own testing date.
Key Takeaway
Start the program-director verification and attestation paperwork the moment you finish your clinical rotations - these documents, not your diploma date, often determine when you can actually schedule the exam.
Eligibility Checklist Before You Apply
Run through this list before you submit an application:
- Completed all coursework and clinical requirements at an ACME-accredited or pre-accredited program.
- Program director has submitted verification of completion to AMCB.
- Attestation of safe, beginning-practitioner performance is on file.
- You do not hold - and do not need - an RN license for this pathway.
- You understand the four-attempt, 24-month testing window that starts at program completion.

Exam Format & Registration Mechanics
Once eligibility is confirmed, the logistics of the exam itself become the priority. PSI administers the computer-based test, and the format is consistent across all candidates:
- 175 four-option multiple-choice questions, including scattered unidentified pretest items mixed throughout the exam.
- Four-hour time limit. Breaks are allowed, but the clock keeps running - plan your pacing accordingly.
- Calculators are prohibited. Any math-based questions must be worked out manually.
- Passing score of 75 on AMCB's 0-100 scaled-score system.
- Results are issued at the testing center immediately after you finish.
The fee structure is straightforward: the initial examination fee is $425, and each retake costs $350. For a full cost breakdown including how these fees fit into your total certification budget, read CM Certification Cost 2026: Complete Pricing Breakdown. If you want a granular look at exactly what a 75 requires and how scaled scoring works, CM Passing Score 2026: Exactly What You Need to Pass covers that in detail.
What Each Domain Actually Tests
Understanding what falls inside each domain matters more than memorizing the percentages, but the percentages tell you where to invest your limited study hours. Here's the breakdown:
| Domain | Weight | Focus |
|---|---|---|
| Antepartum | 21% | Prenatal assessment, risk screening, patient education |
| Intrapartum | 21% | Labor management, fetal monitoring, delivery complications |
| Postpartum | 18% | Maternal recovery, lactation, postpartum complications |
| Well Woman/Gyn | 19% | Annual exams, contraception, gynecologic conditions |
| Women's Health/Primary Care | 11% | Chronic disease management, preventive care |
| Newborn | 10% | Immediate newborn assessment, transition to extrauterine life |
Antepartum (21%)
This domain covers everything from initial prenatal visits through late pregnancy, including risk-factor identification and when a case needs referral beyond midwifery scope.
- Gestational dating and fundal height tracking
- Screening protocols for common pregnancy complications
- Nutrition, education, and psychosocial assessment
Intrapartum (21%)
Tied with Antepartum as the largest domain, this section tests real-time clinical judgment during active labor and delivery.
- Fetal heart rate pattern interpretation
- Stages of labor and appropriate interventions
- Recognizing and responding to intrapartum emergencies
Because Antepartum and Intrapartum together account for 42% of the exam, candidates who under-prepare either domain put a large share of their score at risk. For a domain-by-domain breakdown with more clinical detail on all six areas, see CM Exam Domains 2026: Complete Guide to All 6 Content Areas.
Retake Rules & the 24-Month Window
Requirements don't stop at your first exam attempt - the retake structure is itself a requirement you need to plan around. Candidates get four attempts within 24 months of program completion. Miss that window and you'll need to work through AMCB's process for reestablishing eligibility, which adds time and cost you'd rather avoid.
The wait periods between attempts are fixed:
- First retake: 30-day waiting period after an unsuccessful attempt.
- Second and third retakes: 90-day waiting periods before each subsequent attempt.
Each retake costs $350. If your first attempt doesn't go as planned, that gap between attempts is exactly when a targeted study revision matters most - not a full restart. For strategies specific to closing score gaps efficiently, CM Study Guide 2026: How to Pass on Your First Attempt walks through a structured approach, and How Hard Is the CM Exam? Complete Difficulty Guide 2026 puts the difficulty in context using AMCB's own pass-rate data.
Key Takeaway
AMCB's 2025 combined CNM/CM pass rate was 74.5% for first-time candidates versus 55.5% for repeat candidates - a strong argument for maximizing preparation before attempt one rather than counting on a retake. See CM Pass Rate 2026: What the Data Shows for the full breakdown.
After You Pass: Renewal Requirements
Certification isn't a one-time requirement - it's a five-year cycle with its own recurring obligations. Once issued, your certification runs through the fifth year after issuance. To renew, you have two paths:
- Maintenance route: Complete three maintenance modules plus 20 approved contact hours, along with annual fees.
- Reexamination route: Retake the exam in year four or year five of your certification cycle instead of completing the maintenance modules.
Most working midwives choose the maintenance route since it doesn't require pulling time away from practice for a full exam sitting, but knowing reexamination is an option matters if your continuing-education timeline gets disrupted.
Mapping Requirements to a Study Timeline
Once your eligibility paperwork is filed and your exam date is scheduled, the remaining requirement is simply being ready on test day. Rather than a generic study calendar, build your prep around the domain weights you just reviewed - heavier domains get more weeks, not more hours per day.
Antepartum & Intrapartum
- Drill fetal heart rate interpretation scenarios
- Review risk-screening protocols and referral thresholds
Postpartum & Well Woman/Gyn
- Practice postpartum complication recognition
- Work through contraception and annual-exam question sets
Newborn & Women's Health/Primary Care
- Cover immediate newborn assessment protocols
- Review chronic disease management basics
Full-Length Practice & Timing
- Simulate the 175-question, four-hour format without a calculator
- Review missed items across all six domains
