How to become a labor and delivery or NICU nurse

1. Finish a nursing program that leads to the RN license: an associate degree in nursing (ADN) or a bachelor of science in nursing (BSN). Either one qualifies you for the licensing exam, and the certification board later asks about your license, not your degree.
2. Sit the NCLEX-RN. Passing it, along with your state board's other conditions, earns the RN license (in Canada, the provincial regulator issues it).
3. Get hired onto the unit you want. Some hospitals take new graduates into labor and delivery or the NICU through a residency program; others want acute-care experience first.
4. Work in the specialty until you reach the experience floor both exams share (RN + 24 months + 2,000 h), then apply for the exam that matches your unit.

Steps 1 to 3 make you an L&D or NICU nurse. Step 4 makes you a certified one, and it is voluntary: the credential shows a tested level of specialty knowledge, but practice itself rests on the RN license.

Add up three stretches. The nursing program comes first, and the associate route is the shorter one. Then come the NCLEX-RN and a job offer on the unit, which can be quick or can take a detour through another floor if the hospital does not hire new graduates into L&D or the NICU.

The third stretch is fixed by the board: you need a current, active, unencumbered RN license in the US or Canada, plus 24 months and at least 2,000 hours of RN practice in the specialty. Months and hours are separate tests. A nurse who has been on the unit long enough but works part-time may still be short on hours, so count both before you pay the fee.

Four neighboring units have exams from the same board that are not on Newly Certified yet, so they appear here without links:

• For antepartum-only nurses, RNC-IAP, Inpatient Antepartum Nursing, a separate NCC core exam.
• For mother-baby (couplet) or postpartum nurses, RNC-MNN, Maternal Newborn Nursing.
• For nurses in a low-risk or level II nursery, RNC-LRN, Low Risk Neonatal Intensive Care Nursing.
• For any L&D clinician who wants a credential in fetal heart monitoring alone, C-EFM, a subspecialty exam.

The two exams share almost every rule: the same board, the same eligibility floor, the same length and the same three-option format. What differs is content. RNC-OB is weighted toward labor and birth and pregnancy complications, while RNC-NIC spends most of its questions on pathophysiology and day-to-day NICU management. Fees in the table are 2026 list prices, current as of Nov 6, 2026.

These credentials are easy to confuse, but they test different work:

• RNC-OB, Inpatient Obstetric Nursing, is the full inpatient exam: complications, labor and birth, fetal assessment, recovery and the newborn. Fetal assessment is only 17% of it.
• C-EFM covers electronic fetal monitoring and nothing else. It is a subspecialty credential whose eligibility and format differ; see NCC for both before comparing.
• RNC-MNN, Maternal Newborn Nursing, is built around the postpartum patient and the healthy newborn on a mother-baby unit, not around labor.
• RNC-IAP, Inpatient Antepartum Nursing, is a separate core exam for nurses who care for hospitalized pregnant patients before labor; see NCC for its outline.

For an L&D nurse choosing one credential, the inpatient exam is the broader fit, since fetal monitoring is already part of it. C-EFM can be added later as a second, narrower credential.

NICU nurses have a second option from a different board. CCRN-Neonatal comes from AACN, the critical-care nursing association, with its own clinical-hour rules, exam and renewal; this site does not carry its facts, so see AACN for them. RNC-NIC is the neonatal intensive care exam covered here.

Both are national certifications for nurses caring for critically ill newborns. Clinical ladders sometimes name one, sometimes both, so check yours before choosing. RNC-LRN, mentioned above, is the board's exam for lower-acuity neonatal units; RNC-NIC is the one written for the intensive care NICU.
