Care of the Extremely Low Birth Weight Neonate (C-ELBW) Pass Rate, Format & Study Guide

Care of the Extremely Low Birth Weight Neonate (C-ELBW) is a subspecialty certification from the National Certification Corporation (NCC), the credentialing body for neonatal, obstetric and women's health professionals. The exam tests the knowledge a clinician needs to care for infants born at the lowest birth weights — assessment and management, developmental care, the pathophysiologic states these infants experience, and the psychosocial, ethical and professional issues around their families — in a two-hour computer exam of 125 questions.

Extremely low birth weight infants are among the most fragile patients in any neonatal unit, and their outcomes depend on precise, evidence-based care from the whole team. C-ELBW is open to physicians, nurses, advanced practice nurses, physician assistants, respiratory therapists, neonatal therapists, dietitians, pharmacists and paramedics, so it is one of the few NCC credentials that recognises the interprofessional team caring for these infants.

The exam is aimed at licensed neonatal clinicians in the US or Canada who care for extremely low birth weight infants — NICU nurses, neonatal nurse practitioners and clinical nurse specialists, neonatologists, respiratory therapists, neonatal therapists, dietitians and pharmacists. NCC requires no practice experience but recommends at least one year of experience with this population.

The certifying body does not publicly publish an official pass rate for this exam. Be wary of third-party sites citing a specific number here — treat any pass-rate claim you see elsewhere for this exam as unverified.

NCC allows a candidate who does not pass to retake the exam after a 45-day wait, with the full application and examination fees and no discounts. The Candidate Guide states there is no limit on the number of times a candidate may retake the exam, but certification exams of the same specialty can only be taken twice in a calendar year, and each retest needs a new application that again demonstrates licensure and eligibility.

NCC uses criterion-referenced scoring with item response theory (Rasch analysis) and equating across exam forms, so there is no set percentage passing level; a harder form needs slightly fewer correct answers than an easier one. Your ability level comes from the number of questions answered correctly, with no penalty for wrong answers. The exam has 125 questions, of which 100 are scored; the other 25 are pretest items. Your score report states pass or fail and gives word descriptors (very weak to very strong) for each content area rather than percentages.

The exam has 125 questions: 100 are scored and the remaining pretest items do not count toward your result. You have two hours. Each question has a stem and three possible answers — two distractors and one correct answer — and NCC alphabetises the answer options by their first word and delivers the test in a different random order to each candidate. Questions test both basic knowledge and application of knowledge, and laboratory values appear in conventional units with international units in parentheses.

• General Assessment and Management30%
• Developmental Care16%
• Describe & Manage Pathophysiologic States41%
• Psychosocial, Ethical and Professional Issues and Outcomes with ELBW Neonates and Families13%

NCC's 2026 outline has four content categories: General Assessment and Management (30%), Developmental Care (16%), Describe & Manage Pathophysiologic States (41%), and Psychosocial, Ethical and Professional Issues and Outcomes with ELBW Neonates and Families (13%). The pathophysiologic states category is the largest by a clear margin, so a candidate who is strong clinically but weaker on a specific system should expect it to show up in the score-report descriptors.

Applicants need a current, active and unencumbered licence in the United States or Canada as a physician (MD or DO), registered nurse, advanced practice registered nurse (NNP or CNS), physician assistant, respiratory therapist, neonatal therapist (OT, PT or SLP), neonatal dietitian, neonatal pharmacist or paramedic. NCC states that no practice experience is required, while recommending at least a year of experience caring for extremely low birth weight infants for the best chance of success.

NCC's 2026 Candidate Guide lists the computer exam fee as $210, which includes the non-refundable $50 application fee, and notes that examination fees are subject to change. A change request is $125, and a candidate who withdraws receives $105 of the $210. A retest requires the full application and examination fees with no discounts.

NCC certification must be maintained every three years and lapses if it is not maintained. Maintenance requires 15 hours of continuing education, all of it in Care of the Extremely Low Birth Weight Neonate, earned between your notification of certification and the maintenance due date, plus a maintenance application and fee submitted before that date. Maintenance applications are subject to random audit, and using NCC's own continuing-education modules does not by itself maintain your certification.

With a two-hour, 125-question exam and no published pass rate, plan your study around NCC's outline: Describe & Manage Pathophysiologic States carries 41% of the questions and General Assessment and Management 30%, so spend the largest share of your time there, then Developmental Care (16%) and the psychosocial, ethical and professional area (13%). Work through the competency statements in NCC's Candidate Guide, practise application-style questions rather than recall, and schedule the exam within the first 30 days of your 90-day eligibility window.

NCC publishes a new Candidate Guide each year; this portal follows the 2026 guide. NCC states that examination fees are subject to change, so confirm the current fee and the exam outline on NCC's website before you apply.
