RRT-NPS Exam Domains 2026: Complete Guide to All 2 Content Areas

How the NBRC Structures the NPS Blueprint

The credential most candidates call "RRT-NPS" is earned by passing the National Board for Respiratory Care's Neonatal/Pediatric Specialty Examination (NPS) after you already hold the RRT. The exam is governed by the NBRC's Detailed Content Outline, and the version that matters for 2026 testing took effect on October 1, 2025. That outline divides everything you can be asked into just two domains, and the names below are the exact headings the NBRC uses:

• Domain 1: Competencies Shared Between Critical and General Care of Neonatal or Pediatric Patients
• Domain 2: Competencies Specific to Critical Care of Neonatal or Pediatric Patients

These are not editorial study chapters invented by a prep company. They are the issuer's own organizing structure, and every scored question on your form maps to one of them. If you are building a study plan, start from these two headings rather than from a generic respiratory textbook table of contents. For a broader preparation framework once you understand the blueprint, see our RRT-NPS study guide for passing on your first attempt.

Exam Format and Testing-Center Logistics

Before you can map content to domains, you need an accurate picture of the container. The NPS is a closed-book, computer-based examination delivered by PSI. You face 170 multiple-choice questions in four hours. Of those, 150 are scored and 20 are unidentified pretest items the NBRC is trialing for future forms. You cannot tell which are which, so every question deserves your full effort.

Two practical points deserve emphasis. First, remote proctoring is no longer an option: the NBRC discontinued live remote proctoring after December 31, 2024, and testing-center delivery has been required since January 1, 2025. Any older advice about testing from home is obsolete. Second, "linear-on-the-fly" means the exam does not adapt its difficulty to your answers the way a computer-adaptive test would. Your form is assembled to meet the blueprint, and the difficulty you experience does not signal whether you are passing. Check our guide to testing windows and scheduling for the scheduling side of logistics.

Because four hours across 170 questions leaves a limited pace per item, and breaks consume that clock, rehearse sitting through a full-length session in advance. Our practice test site is built to help you build that stamina against realistic neonatal and pediatric scenarios.

Domain 1: Shared Competencies (80 Scored Items)

Domain 1 is the bigger of the two, and its title tells you how to think about it: these are skills used whether the infant or child is in a NICU or PICU, on a general pediatric floor, or in a step-down setting. The NBRC outline lists the following subordinate coverage, which is the real checklist you should study against.

What this looks like in a question stem

Domain 1 items tend to hand you a patient scenario and ask you to interpret, select, or decide. Expect to see an infant or child described by gestational or chronological age, with vital signs, breath sounds, blood gas or imaging results, and a current support level. The question may then ask for the most likely cause of the compromise, the best next assessment, or the equipment adjustment that addresses a described problem. Because "causes of respiratory compromise" and "diagnostic results" share the domain, you must be able to connect a lab or imaging finding to a physiologic explanation and then to an action.

The topics candidates underestimate

Nutrition, interdisciplinary collaboration, and patient and family education look softer than airway management, but they are explicit parts of the outline and can appear as scored items. Think about how nutrition intersects with respiratory workload and growth in a chronically ventilated infant, how you would communicate a plan to a family member who is frightened, and how you hand off concerns to the neonatologist, intensivist, nurse, or dietitian. Resuscitation, by contrast, rewards precise recall of the sequence and decision points for neonatal and pediatric patients, since the right action depends heavily on age group and presenting rhythm or respiratory status.

If you are weighing how demanding this material is relative to your background, our analysis of how hard the RRT-NPS exam really is puts it in context.

Domain 2: Critical-Care-Specific Competencies (70 Scored Items)

Domain 2 narrows to the skills that belong to intensive care of neonatal and pediatric patients. It has fewer scored items than Domain 1, but each one tends to demand a deeper chain of reasoning. The outline covers:

Specialty gases

This is a distinctly neonatal and pediatric critical-care topic. You should be prepared to reason about when a specialty gas is indicated, what monitoring it requires, how to titrate or wean it, and what hazards or complications you must watch for. Questions in this area frequently pair a clinical picture with a therapy choice, so know the indications and the physiologic rationale rather than memorizing isolated facts.

Medication administration

Note the difference in wording between the two domains. Domain 1 addresses "medication effects/interactions," while Domain 2 addresses "medication administration." In the critical-care domain, expect questions about delivering medications to patients on advanced support, selecting an appropriate delivery approach, and recognizing a response or adverse effect in a sick infant or child.

End-of-life care

This is the one subsection that tests judgment and communication as much as physiology. Candidates should understand the respiratory therapist's role when goals of care shift, how to support comfort, and how to work with the family and care team. Do not skip it because it feels uncomfortable; it is an explicitly listed part of Domain 2.

Why Ventilation and Oxygenation Deserves Its Own Plan

Within Domain 2, the ventilation and oxygenation subsection accounts for 30 scored items. That is a large concentration inside one subsection of a 150-item scored exam, and it is the clearest single place where focused study pays off. For comparison, the entire remainder of Domain 2 (pertinent critical-care information, specialty gases, procedural efficacy, medication administration, and end-of-life care) shares the other 40 scored items.

Case-based reasoning to rehearse

The skill the exam rewards is working from a described patient to a ventilator or oxygenation decision. Practice walking through scenarios in this order:

1. Identify the problem: Is the issue ventilation (carbon dioxide clearance), oxygenation, or both? Read the gas values and clinical picture before looking at the answer choices.
2. Link it to the cause: Tie the abnormality to the underlying neonatal or pediatric condition described, whether pulmonary or not.
3. Choose the adjustment: Decide which setting or therapy would change the specific variable that is wrong, and predict the expected effect.
4. Anticipate consequences: Consider what the change could do to the patient's lungs, circulation, or comfort, and how you would confirm that it worked.

This habit keeps you from picking an answer that sounds familiar but fixes the wrong problem. It also pairs naturally with the "procedural efficacy" language in both domains, which asks whether an intervention actually achieved its goal. For quick-reference recall of the numbers and relationships you will use in these cases, our one-page RRT-NPS cheat sheet is a handy companion.

Cross-Cutting Cases: Neonatal, Pediatric, Pulmonary and Non-Pulmonary

The outline also describes case coverage that cuts across both domains. Questions draw on neonatal and pediatric disorders, both pulmonary and non-pulmonary, plus general care. That means a Domain 1 or Domain 2 item may be built around a condition where the primary problem is not in the lungs at all, such as a cardiac, neurologic, or metabolic issue with respiratory consequences.

The practical takeaway is to study disorders through their respiratory implications. For each condition you review, ask what the airway, gas exchange, and support needs look like, how you would assess the patient, and what a respiratory therapist should do. This integrated approach serves both domains at once.

Scheduling Your Weeks by Domain

This is the only study-method section in this article, and it is tied directly to the blueprint. Because Domain 1 has more scored items but Domain 2 contains the 30-item ventilation/oxygenation block, a sensible plan front-loads breadth, then deepens the heavy subsection, then tests everything under timed conditions.

Adjust the length to your own timeline; the ordering logic is what matters. After each practice session, sort your errors into Domain 1 or Domain 2 and then into subsection, so you can see whether a pattern of misses concentrates in a particular area. Remember that third-party practice products may use different question counts and timers than the real exam, so use them for skills rather than as a prediction of the actual 170-question, four-hour experience.

Eligibility, Fees and Retake Rules

The prerequisite is that you hold the NBRC RRT credential. The NPS admission policy does not add a specified NICU employment duration, a separate training-hour minimum, or a reference requirement, so a newly credentialed RRT is not automatically excluded by experience rules. That said, the content assumes familiarity with neonatal and pediatric care, so exposure to those patients will make the material far easier. Our RRT-NPS requirements guide walks through eligibility in more detail.

The AARC discount is not a universal membership perk. It applies only to qualifying members who use the prescribed process, and it cannot be claimed after the fact. For a fuller view of what you will spend, see the RRT-NPS certification cost breakdown.

The NBRC also offers a free official practice examination and a paid self-assessment. These are preparation resources, not additional mandatory qualifying exams, so you are not required to complete them before applying.

Reading the Pass-Rate Data Against the Blueprint

The NBRC's 2025 Examinations in Review reports that the NPS new-candidate pass rate was 63.4%, while the repeat-candidate rate was 40.4%. The NBRC administered 1,712 NPS examinations and awarded 961 credentials that year. Keep two cautions in mind. First, those 2025 figures span the October blueprint transition, so they are not exclusively outcomes for the current version of the outline, and no full-year 2026 results are asserted here. Second, the NBRC reports raw correct-answer totals compared with an expert-panel-derived cut score, and a current NPS numeric cut score was not verified in public issuer materials, so no fixed percentage should be treated as the passing line.

The gap between first-time and repeat rates is a useful signal: candidates who retake face meaningfully lower odds, which argues for thorough preparation before the first sitting rather than treating attempt one as a trial run. Dig into this further in our RRT-NPS pass rate analysis and our explainer on the passing score and how scoring works.

After the Exam: Maintenance and Career Fit

An NPS credential is valid for five years from the end of the issuance month. Under the Credential Maintenance Program (CMP), you choose among alternatives rather than completing all of them: assessment and continuing-education compliance, retaking the highest applicable credential examination in the last year of the term, or earning a new NBRC credential. Assessment performance sets your CE documentation at 0, 15, or 30 credits. For an RT plus one specialty, the current chart splits the 30-credit requirement into 15 general respiratory and 15 specialty credits, or the 15-credit requirement into 7.5 and 7.5. Other credential combinations allocate differently.

CMP annual fees are $25 for payment years before 2027 and $30 from payment year 2027, which means a five-year term entirely at the higher rate totals $150. Examination-based renewal instead requires the relevant exam fee, and state license renewal is a separate obligation.

Where the credential is used

The NPS signals specialty competence for therapists who care for critically ill newborns and children, typically in neonatal and pediatric intensive care units and the children's hospital settings that support them. Browse the RRT-NPS jobs overview for the employer types that look for this background. On pay, general respiratory therapist compensation and employer-specific incentives should be distinguished from a demonstrated certification premium, and no credential-specific salary uplift has been established here; our salary guide and ROI analysis discuss how to evaluate it for your own situation.

If you are deciding between specialties, remember the NPS focuses on neonatal and pediatric patients, whereas the Adult Critical Care Specialty (ACCS) focuses on adults. They are different credentials with different scopes, so choose based on the patient population you want to serve.
