- RRT-NPS means Registered Respiratory Therapist who also holds the NBRC Neonatal/Pediatric Specialist credential.
- The NPS exam has 170 questions: 150 scored plus 20 unidentified pretest items, in four hours.
- You must already hold the NBRC RRT credential before applying for the NPS examination.
- 2025 new-candidate pass rate was 63.4%; repeat candidates passed at 40.4%.
What the Letters Actually Mean
The acronym is a stack of two credentials. RRT stands for Registered Respiratory Therapist, the advanced-level respiratory therapy credential awarded by the National Board for Respiratory Care (NBRC). NPS stands for Neonatal/Pediatric Specialist, the specialty credential earned by passing the NBRC Neonatal/Pediatric Specialty Examination. Written together, RRT-NPS tells an employer that a clinician is a registered therapist with demonstrated competence in the care of newborns, infants, and children.
The two parts do different jobs. The RRT establishes the general respiratory care foundation. The NPS signals a narrower, higher-acuity skill set: ventilating a 600-gram preterm infant is a very different task from managing an adult COPD exacerbation, and the specialty credential exists to recognize that difference. If you want a plain-language introduction before going deeper, the companion pieces What Is RRT-NPS? and What Does RRT-NPS Stand For? cover the basics from different angles.
Who Awards the Credential
The NPS credential is issued by the National Board for Respiratory Care, the same body that administers the entry-level and advanced respiratory therapy examinations. Testing is delivered through PSI testing centers. The NBRC publishes the exam's Detailed Content Outline, and the version currently in effect took effect on October 1, 2025.
That issuer detail matters because of how crowded the abbreviation is. When you research the credential, anchor your searches and your sources to the NBRC. Anything that does not trace back to the NBRC's own examination materials is not describing this credential.
Why the Acronym Causes Confusion
Searching the letters "NPS" alone tends to return unrelated results, including nurse-practitioner material and other fields entirely. Candidates and hiring managers occasionally mix these up. Three habits prevent most mistakes:
- Pair the abbreviation with "NBRC," "respiratory," or "neonatal pediatric" whenever you search.
- Check that any study resource describes a four-hour, 170-question computer-based examination with respiratory therapy content.
- Confirm that a resource references the NBRC's own content outline rather than a generic "specialist" syllabus.
Related wording variants such as What Does RRT-NPS Mean? and What Is A RRT-NPS? address the person holding the credential rather than the exam itself, which is a useful distinction when you are writing a job application or updating a profile.
What the Exam Measures
The NPS examination is built around two exam domains, and the NBRC assigns scored items to each rather than publishing percentages. That is worth stating carefully: Domain 1 carries 80 scored items and Domain 2 carries 70, so Domain 1 has the larger allocation, but no official percentage weights are printed in the outline. For a deeper walk through both areas, see the complete guide to the RRT-NPS exam domains.
Domain 1: Competencies Shared Between Critical and General Care of Neonatal or Pediatric Patients
This is the larger domain, with 80 scored items. It covers the skills a neonatal or pediatric respiratory therapist uses regardless of whether the patient is in an intensive care unit or on a general ward.
- Patient assessment and identifying causes of respiratory compromise
- Evaluating pulmonary status and interpreting diagnostic results
- Airway management and resuscitation
- Selecting equipment and troubleshooting it
- Judging procedural efficacy and applying patient-care protocols
- Medication effects and interactions
- Nutrition as it relates to respiratory status
- Interdisciplinary collaboration and patient and family education
Domain 2: Competencies Specific to Critical Care of Neonatal or Pediatric Patients
This domain has 70 scored items and concentrates on the intensive care environment.
- Pertinent critical-care information
- Specialty gases
- Ventilation and oxygenation, which accounts for 30 of the domain's scored items
- Procedural efficacy and medication administration
- End-of-life care
Notice where the concentration sits: ventilation and oxygenation is the single largest subsection inside Domain 2. Candidates who treat it as one topic among many tend to be surprised by how much case reasoning it demands. Expect to read a clinical scenario, interpret blood gas values and ventilator settings, and decide what to change and why, rather than recall an isolated fact.
Question Style and Test Format
Every question is multiple choice. The examination is assembled linear-on-the-fly, which means it is not computer-adaptive: your performance on early questions does not steer you toward easier or harder ones. The outline also includes patient-type minipools covering neonatal and pediatric pulmonary and non-pulmonary disorders plus general care, but those pool counts are not a guarantee that any specific disease will appear on your particular form.
- Length: 170 questions, of which 150 are scored and 20 are unidentified pretest items.
- Time: four hours, and breaks do not stop the clock.
- Tools: closed book with an on-screen calculator; personal calculators and reference materials are not permitted.
- Scoring: your raw number of correct answers is compared with an expert-panel-derived cut score. A numeric cut score was not verified in the public materials, so treat any fixed "passing percentage" you see online with caution. The article on the RRT-NPS passing score explains what is and is not known.
How the Credential Is Earned
The pathway is short on paper. The single prerequisite is holding 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. That is often a relief to newly credentialed therapists who assumed years of bedside time were mandatory. Whether you are ready is a clinical and preparation question, not a paperwork one. The full eligibility picture is in the RRT-NPS requirements guide.
Fees and Registration Mechanics
| Item | Detail |
|---|---|
| First application fee | $250 |
| Reapplication fee | $220 |
| One-time AARC member first-application discount | $40 off, for a $210 first attempt when eligible |
| Application window | Accepted year-round |
| Testing delivery | PSI testing center only |
The AARC discount is not automatic. It requires going through the prescribed AARC registration or email-link process, it applies once to a first application, and it is not applied retroactively if you pay first and join later. For a fuller accounting that includes preparation and renewal costs, read the RRT-NPS certification cost breakdown.
Testing Center Only
Remote testing is not a current option. The NBRC discontinued live remote proctoring after December 31, 2024, and has required PSI testing-center delivery since January 1, 2025. Older blog posts and forum threads that mention taking the NPS from home are out of date. Plan for travel time, center availability, and a four-hour sitting. Scheduling specifics are covered in the RRT-NPS exam dates guide.
If You Do Not Pass
Two initial attempts are permitted without the subsequent-attempt waiting restriction. Later attempts require 180 days between attempts. Published 2025 results show how much the retake picture differs: the new-candidate pass rate was 63.4% and the repeat-candidate rate was 40.4%. The NBRC reported 1,712 NPS examinations administered that year and 961 credentials awarded. Those 2025 figures span the October blueprint transition, so they are not exclusively outcomes for the current version of the exam. More context is in the RRT-NPS pass rate analysis.
Key Takeaway
Because repeat candidates passed at a noticeably lower rate than first-timers, the most efficient plan is to prepare thoroughly before the first sitting rather than treating it as a trial run. Use the free official practice examination and paid self-assessment as diagnostic tools; they are preparation resources, not additional mandatory qualifying exams.
NPS Compared With Related NBRC Credentials
The NBRC offers more than one route to specialization, and RRT-NPS is easy to confuse with its neighbors. The table below separates them using only the scope of each credential.
| Credential | Population focus | Relationship to RRT |
|---|---|---|
| RRT | General respiratory care | The base credential and the NPS prerequisite |
| NPS (Neonatal/Pediatric Specialist) | Neonates and children, general and critical care | Specialty earned after holding the RRT |
| ACCS (Adult Critical Care Specialist) | Adult critical care | A different specialty; not interchangeable with NPS |
The practical decision comes down to patient population. A therapist who spends most shifts in a NICU or pediatric ICU belongs on the NPS path; one in an adult ICU is a better fit for ACCS. Neither replaces the RRT, and neither is a step toward becoming a nurse practitioner, which is an entirely different profession that happens to share the letters. Note also that the NPS is separate from NNP certification, which belongs to advanced practice nursing.
Where the Credential Matters at Work
Employers that care for small, sick patients are the natural audience: children's hospitals, level III and IV neonatal intensive care units, pediatric intensive care units, and transport teams that move critically ill newborns and children between facilities. In those settings the specialty credential communicates readiness for tasks such as neonatal ventilation strategies, specialty gas therapy, and participation in resuscitation.
Be realistic about what the credential does and does not prove in pay terms. General respiratory therapist compensation is well documented, but no credential-specific salary uplift for the NPS has been established. Some employers offer certification incentives, differential pay, or preferential hiring for specialty units; others do not. Treat any claim of a guaranteed raise skeptically and ask your own employer directly. The RRT-NPS salary guide and the analysis of whether the certification is worth it walk through how to evaluate the return for your situation, and the RRT-NPS jobs overview describes the employer types that tend to recruit for it.
One more perspective on scale: through December 31, 2025, the NBRC had awarded a cumulative 21,002 NPS credentials. That is a historical count of awards, not the number of therapists currently practicing with an active credential.
Keeping the Credential Active
An NPS credential is valid for five years from the end of the month it was issued. Maintenance runs through the NBRC Credential Maintenance Program (CMP), and the current program brochure was revised October 7, 2026. You have alternatives, not three mandatory tests:
- Assessment and continuing education compliance: your assessment performance sets how much CE documentation you owe, at 0, 15, or 30 credits.
- Re-examination: retake the highest applicable credential examination in the last year of the term.
- Earn a new NBRC credential: a newly earned credential can serve the renewal purpose.
For a therapist holding the RRT plus one specialty, the current chart divides the 30-credit requirement into 15 general respiratory and 15 specialty credits, or the 15-credit requirement into 7.5 general and 7.5 specialty credits. Other credential combinations have different allocations, so check the NBRC's chart rather than assuming.
Renewal Costs and the 2027 Change
CMP annual fees are $25 for payment years before 2027 and $30 from payment year 2027 onward. A five-year term entirely at the higher rate totals $150. If you choose examination-based renewal instead, you pay the relevant examination fee. State license renewal is a separate obligation with its own fees and requirements, so do not assume NBRC maintenance satisfies your state.
Sensible First Steps
Rather than a generic study schedule, let the blueprint dictate the order. A reasonable way to use the domain structure:
Domain 1 foundations
- Because Domain 1 carries 80 scored items, start with assessment, airway management, equipment troubleshooting, and resuscitation
- These topics also feed the reasoning you need in Domain 2
Ventilation and oxygenation cases
- Spend concentrated time here, since it holds 30 scored items inside Domain 2
- Practice reading a scenario, interpreting gases and settings, then choosing an adjustment
Specialty gases, medications, end-of-life care
- Close remaining Domain 2 gaps
- Take the official free practice examination under timed conditions to rehearse the four-hour pace
From there, a structured plan helps. The RRT-NPS study guide lays out a full preparation approach, the difficulty guide sets expectations honestly, and the one-page cheat sheet is handy for last-week review. To test yourself against realistic scenario questions, try the RRT-NPS practice tests and compare your results against the blueprint areas above. You can also review the broader overview in RRT-NPS Certification and the training perspective in RRT-NPS Training.
Frequently Asked Questions
RRT-NPS combines Registered Respiratory Therapist (RRT) with Neonatal/Pediatric Specialist (NPS). The RRT is the base NBRC credential, and the NPS is the specialty credential earned by passing the NBRC Neonatal/Pediatric Specialty Examination.
The NBRC's NPS admission policy requires the RRT credential but does not specify a NICU employment duration, separate training-hour minimum, or reference requirement. Clinical familiarity still helps enormously, since the questions are case-based.
It has 170 multiple-choice questions, with 150 scored and 20 unidentified pretest items, over four hours. The first application fee is $250 and reapplication is $220; eligible AARC members can get a one-time $40 first-application discount through the prescribed process.
No. The NBRC discontinued live remote proctoring after December 31, 2024, and since January 1, 2025 requires delivery at a PSI testing center.
It is valid for five years from the end of the issuance month. You can maintain it through the Credential Maintenance Program with assessment and CE compliance, retake the highest applicable credential examination in the last year of the term, or earn a new NBRC credential. State license renewal is separate.
