- BMTCN is being renamed the Transplantation and Cellular Therapy Certified Nurse (TCTCN) on January 1, 2026.
- The exam has 165 questions (125 scored, 40 pretest) delivered in a 3-hour PSI-administered session.
- Passing requires a scaled score of 55 on a 25-75 scale, based on the 2024 role delineation study.
- Four of six domains are tied at 22% weight each, covering foundations through post-cellular therapy management.
What Is BMTCN Certification?
The Blood and Marrow Transplant Certified Nurse (BMTCN) credential is a specialty nursing certification administered by the Oncology Nursing Certification Corporation (ONCC) for registered nurses who care for patients undergoing hematopoietic stem cell transplantation (HSCT) and related cellular therapies. It signals that a nurse has verified clinical experience and has demonstrated mastery of a defined body of transplant and cellular therapy nursing knowledge through a standardized exam.
A significant change is coming to this credential: effective January 1, 2026, ONCC is renaming BMTCN to the Transplantation and Cellular Therapy Certified Nurse (TCTCN). The name change reflects how far the specialty has expanded beyond traditional marrow transplant into CAR T-cell therapy and other cellular treatments, but the exam continues to be delivered through PSI testing centers under ONCC's oversight. If you already hold or are pursuing the BMTCN, understanding this transition matters - it affects how you'll see the credential referenced in job postings, continuing education materials, and renewal paperwork going forward.
If you're still deciding whether this specialty certification is the right move, the overview at What Is BMTCN Certification? and the plain-language breakdown in BMTCN Meaning are good starting points before you dive into exam mechanics.
Who Should Pursue the BMTCN?
This certification is built for RNs working directly with HSCT and cellular therapy patients - inpatient transplant units, outpatient infusion and apheresis centers, stem cell collection facilities, and cellular therapy programs affiliated with academic medical centers. Nurse coordinators, transplant navigators, and bedside nurses managing conditioning regimens, engraftment, and graft-versus-host disease all fall within the target audience.
Employers that run active transplant and cellular therapy programs frequently list this credential as preferred or required for senior clinical roles. If you're mapping out where certified nurses land, BMTCN Jobs outlines the settings and role types where this credential carries the most weight.
Exam Format and Structure
The BMTCN exam consists of 165 multiple-choice questions total, but only 125 of those are scored. The remaining 40 are pretest items used by ONCC to evaluate future exam content - they're mixed in throughout the exam and not distinguishable from scored questions, so every question deserves your full attention. Candidates get a 3-hour session to complete the exam.
Passing requires a scaled score of 55 on a 25-75 scale, not a raw percentage of questions answered correctly. This scaling accounts for slight difficulty variation between exam forms, which is why memorizing a single "number of correct answers needed" isn't useful. For a full breakdown of how the scaled score works and what it means for your preparation, see BMTCN Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Treat all 165 questions as scored since you cannot identify which 40 are pretest items - pacing and focus should stay consistent from question one through question 165.
The Six Exam Domains
The exam blueprint is based on ONCC's 2024 role delineation study, which surveyed practicing transplant and cellular therapy nurses to determine what content areas matter most in real clinical practice. Four domains are tied for the largest weight at 22% each, meaning nearly 90% of the exam sits across just four content areas.
Domain 1: Foundations of HSCT and Cellular Therapy (22%)
Covers the underlying science and clinical rationale behind transplant and cellular therapy - indications, donor selection, graft sources, and conditioning regimen principles.
- Transplant types and cellular therapy modalities
- Pre-transplant workup and eligibility criteria
Domain 2: HSCT and Cellular Therapy Process and Administration (22%)
Focuses on the mechanics of collection, processing, and infusion - apheresis, cell manipulation, and administration safety.
- Collection and cryopreservation basics
- Infusion-related reactions and monitoring
Domain 3: Post-HSCT Management and Education (22%)
Addresses engraftment, complications, and patient/caregiver education following stem cell transplant.
- Graft-versus-host disease recognition and management
- Infection risk and prophylaxis during engraftment
Domain 4: Post-Cellular Therapy Management and Education (22%)
Parallels Domain 3 but centers on cellular therapies such as CAR T-cell products, including their distinct toxicity profiles.
- Cytokine release syndrome and neurotoxicity recognition
- Long-term monitoring after cellular therapy infusion
Domain 5: Quality of Life (8%)
Covers survivorship, psychosocial support, and long-term quality-of-life considerations for transplant and cellular therapy patients.
Domain 6: Professional Performance (4%)
Addresses the nurse's role in ethics, coordination of care, and professional responsibilities within the transplant team.
For question-level detail on each domain and how ONCC weights specific subtopics, the full breakdown in BMTCN Exam Domains 2026: Complete Guide to All 6 Content Areas is worth reviewing before you build a study plan. If you're trying to gauge overall exam difficulty relative to your clinical background, How Hard Is the BMTCN Exam? Complete Difficulty Guide 2026 walks through what makes certain domains harder to master than others.
Eligibility Requirements
ONCC sets four eligibility criteria that candidates must satisfy before scheduling the exam:
- A current, active, unencumbered RN license in the United States, its territories, or Canada
- Two years of RN experience within the previous four years
- 2,000 hours of HSCT or cellular-therapy nursing practice within the previous four years
- 10 relevant contact hours of continuing education within the previous three years
The hour and contact-hour requirements are the pieces candidates most often underestimate - 2,000 clinical hours is substantial, and it must be specific to HSCT or cellular-therapy nursing, not general oncology practice. A detailed walkthrough of how to document and verify each requirement is available in BMTCN Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Registration and Fees
ONCC prices the exam at $300 for ONS or APHON members and $420 for nonmembers. Candidates can also purchase an optional $100 DoubleTake retake add-on, which allows a second exam attempt without paying the full fee again if the first attempt is unsuccessful.
| Fee Type | Amount |
|---|---|
| ONS/APHON Member Rate | $300 |
| Nonmember Rate | $420 |
| Optional DoubleTake Retake Add-On | $100 |
Joining ONS or APHON before registering can offset the membership cost through exam savings alone, depending on your situation. For the complete cost picture - including how the DoubleTake option factors into a total budget - see BMTCN Certification Cost 2026: Complete Pricing Breakdown. Testing windows and scheduling logistics through PSI are covered in BMTCN Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Certification Validity and Renewal
Once earned, ONCC certification is valid for four years. Nurses need to plan ahead for renewal requirements well before the certification expires, since lapses can affect employer credentialing timelines and any differential pay tied to active certification status. Given the upcoming rename to TCTCN, nurses certifying now should expect renewal materials and continuing education tracking to eventually reference the new credential name even if their original certificate reads BMTCN.
Building a Domain-Driven Study Plan
Because four domains carry equal 22% weight, an effective study plan treats them as a connected sequence rather than four isolated silos. Foundations (Domain 1) sets up the science you need before Process and Administration (Domain 2) makes sense, and the two post-treatment domains (3 and 4) build directly on what happens during collection and infusion.
Domain 1: Foundations
- Review transplant types, donor sources, and conditioning regimens
- Build a reference sheet of graft types and indications
Domain 2: Process and Administration
- Study apheresis, collection, and infusion safety protocols
- Practice questions on infusion-related complications
Domains 3 and 4: Post-Treatment Management
- Compare GVHD management against cellular therapy toxicities like CRS
- Drill patient education scenarios for both pathways
Domains 5 and 6: Quality of Life and Professional Performance
- Review survivorship and psychosocial support concepts
- Cover ethics and care-coordination responsibilities
Full Review and Practice Exams
- Take timed practice sets replicating the 3-hour, 165-question format
- Revisit weak domains identified through practice performance
Rather than generic flashcard review, weight your practice time to match the blueprint - spend roughly equal time across the four 22% domains, then a lighter pass on Quality of Life and Professional Performance. A structured walkthrough of this approach, including where candidates commonly lose points, is in BMTCN Study Guide 2026: How to Pass on Your First Attempt. Running full-length timed sets on our practice test platform before exam day helps confirm your pacing holds up across all 165 questions, not just the first hour.
