- A BMTCN is a Blood and Marrow Transplant Certified Nurse credentialed through the Oncology Nursing Certification Corporation (ONCC).
- Starting January 1, 2026, ONCC delivers this credential under a new name - Transplantation and Cellular Therapy Certified Nurse (TCTCN).
- The exam has 165 multiple-choice questions (125 scored, 40 pretest) in a 3-hour session, delivered via PSI.
- Passing requires a scaled score of 55 on a 25-75 scale; certification is valid for four years.
What Is a BMTCN, Exactly?
A BMTCN - Blood and Marrow Transplant Certified Nurse - is a registered nurse who has demonstrated specialized knowledge in caring for patients undergoing hematopoietic stem cell transplantation (HSCT) and cellular therapies. This is not a generic oncology credential. It validates competence in a narrow, high-acuity clinical niche: conditioning regimens, stem cell infusions, engraftment monitoring, graft-versus-host disease management, and the long-term follow-up these patients require.
The certification is earned by passing a standardized exam built from a formal role delineation study - research into what practicing transplant and cellular therapy nurses actually do day to day. That study directly shapes the exam blueprint, which is why the content areas map so closely to real bedside and outpatient transplant unit responsibilities.
If you're still mapping out terminology before diving into study materials, our companion pieces on BMTCN Meaning and What Does BMTCN Stand For? break down the acronym itself, while this article focuses on what the credential actually requires and represents.
Who Awards It - and the TCTCN Name Change
The Oncology Nursing Certification Corporation (ONCC) has historically administered this credential under the BMTCN name. Effective January 1, 2026, ONCC transitions the credential to a new title: Transplantation and Cellular Therapy Certified Nurse (TCTCN). The exam itself continues to be delivered through PSI testing centers, and the underlying scope of practice - HSCT and cellular therapy nursing - remains the same. If you're researching this credential in 2026 or beyond, you may see both names referenced; they describe the same certification pathway and the same body of clinical knowledge.
For readers who want the full historical and naming context in one place, see BMTCN Certification and What Is BMTCN?, which cover how the credential fits within ONCC's broader oncology certification portfolio.
Exam Format and Scoring
The exam consists of 165 multiple-choice questions administered in a 3-hour testing session. Of those, 125 questions are scored and 40 are unscored pretest items used to evaluate future exam questions - candidates cannot tell which is which, so every question should be treated as if it counts.
To pass, candidates must reach a scaled score of 55 on a 25-75 scale. This is not a raw percentage; ONCC uses scaled scoring to account for slight difficulty variations between exam forms. Once earned, certification remains valid for four years before renewal is required.
For a deeper breakdown of exactly what that scaled score means and how it's calculated, read BMTCN Passing Score 2026: Exactly What You Need to Pass. If you're trying to gauge how challenging the exam actually is relative to other nursing certifications, How Hard Is the BMTCN Exam? Complete Difficulty Guide 2026 walks through question style and cognitive demand in more detail.
Key Takeaway
Because 40 of the 165 questions are unscored pretest items, don't waste mental energy trying to guess which questions "matter" - pace yourself evenly across all 165 within the 3-hour window.
The Six BMTCN Exam Domains
The exam blueprint, built from the 2024 role delineation study, organizes content into six domains. Four of them are weighted equally and together make up the bulk of the exam, so candidates should not assume one "main" domain dominates preparation - mastery needs to be spread across four large content areas plus two smaller ones.
Domain 1: Foundations of HSCT and Cellular Therapy (22%)
Covers the underlying science and rationale behind transplant and cellular therapy: indications, donor selection principles, conditioning regimen categories, and the biological basis of engraftment.
- Disease indications for autologous vs. allogeneic HSCT
- Donor and product sourcing considerations
Domain 2: HSCT and Cellular Therapy Process and Administration (22%)
Focuses on the operational and clinical mechanics of delivering transplants and cellular therapy products, including infusion protocols and acute administration-related complications.
- Stem cell collection and cryopreservation basics
- Infusion-related reactions and immediate monitoring
Domain 3: Post-HSCT Management and Education (22%)
Addresses the clinical course after transplant: engraftment tracking, graft-versus-host disease, infection risk, and educating patients and caregivers through recovery.
- Acute and chronic GVHD recognition and management
- Infection prevention during immune reconstitution
Domain 4: Post-Cellular Therapy Management and Education (22%)
Parallels Domain 3 but centers on cellular therapies such as CAR T-cell treatment, including their distinct toxicity profiles and monitoring needs.
- Cytokine release syndrome recognition and grading
- Neurotoxicity monitoring specific to cellular therapy products
Domain 5: Quality of Life (8%)
Covers the psychosocial, survivorship, and long-term functional concerns transplant and cellular therapy patients face beyond acute medical management.
- Long-term survivorship and late-effects screening
- Psychosocial support and caregiver burden
Domain 6: Professional Performance (4%)
The smallest domain, focused on professional practice standards, ethics, and evidence-based practice within transplant nursing.
- Ethical decision-making in high-acuity transplant care
- Application of research and evidence-based guidelines
Because four domains are tied at 22% weight each, an effective study plan can't lean too heavily on any single area. For a full domain-by-domain content breakdown with more granular subtopics, see BMTCN Exam Domains 2026: Complete Guide to All 6 Content Areas.
Eligibility Requirements
Before scheduling an exam, candidates must meet several eligibility criteria set by ONCC:
- Hold a current, active, unencumbered RN license in the United States, a U.S. territory, or Canada.
- Have at least two years of RN practice experience within the previous four years.
- Accumulate 2,000 hours of HSCT or cellular-therapy nursing practice within the previous four years.
- Complete 10 contact hours of relevant continuing education within the previous three years.
These thresholds exist because this credential is meant to validate hands-on transplant unit experience, not just classroom knowledge. If you're unsure whether your current role or hours qualify, BMTCN Requirements 2026: Eligibility, Prerequisites & How to Qualify walks through documentation and edge cases in detail.
Registration Fees and Costs
Exam fees are $300 for ONS or APHON members and $420 for nonmembers. Candidates who don't pass on their first attempt can add an optional $100 DoubleTake retake option, which allows a second exam attempt without paying the full fee again.
| Item | Cost |
|---|---|
| ONS/APHON member exam fee | $300 |
| Nonmember exam fee | $420 |
| Optional DoubleTake retake add-on | $100 |
Membership in ONS or APHON before you register can meaningfully lower the base cost, so it's worth checking membership status ahead of your application window.

Who Pursues This Credential - and Who Hires For It
Nurses who pursue this certification typically work in bone marrow transplant units, inpatient oncology floors that manage HSCT patients, outpatient cellular therapy infusion centers, and apheresis or stem cell collection units. As CAR T-cell and other cellular therapies expand beyond academic transplant centers, demand has grown for nurses who understand both traditional HSCT care and newer cellular therapy toxicity management - which is exactly why the exam blueprint splits post-transplant management into two distinct domains (Domains 3 and 4) rather than treating them as one topic.
Employers value this credential as evidence that a nurse can independently manage the complex, rapidly-changing clinical picture of a transplant or cellular therapy patient without constant oversight. For a look at how the credential connects to job titles, unit types, and career progression, see BMTCN Jobs. Compensation implications specific to this specialty are discussed in BMTCN Salary Guide 2026: Complete Earnings Analysis.
How to Prepare Strategically
Because four domains carry equal weight, an effective study sequence should treat them as four roughly equal blocks rather than front-loading one topic. A simple approach: dedicate focused weeks to each of the four major domains before layering in the smaller Quality of Life and Professional Performance content, which can be reviewed together since they're lighter in weight but still test-relevant.
Foundations of HSCT and Cellular Therapy
- Review conditioning regimens and donor selection criteria
- Build a reference sheet of transplant indications by disease type
Process and Administration
- Walk through infusion protocols and immediate complication management
- Practice recognizing acute reaction symptoms in scenario-style questions
Post-HSCT and Post-Cellular Therapy Management
- Contrast GVHD management with CRS and neurotoxicity management
- Drill the distinctions between Domain 3 and Domain 4 content, since they overlap in structure but differ in specifics
Quality of Life and Professional Performance
- Review survivorship, psychosocial support, and ethics content
- Take a full-length timed practice run to simulate the 3-hour, 165-question format
For a structured, week-by-week plan built specifically around this blueprint, see BMTCN Study Guide 2026: How to Pass on Your First Attempt. Once you've reviewed content, practicing under timed conditions on our practice test platform helps you get comfortable with the pacing needed to finish all 165 questions inside a 3-hour session. A quick-reference summary of high-yield facts across all six domains is also available in the BMTCN Cheat Sheet 2026: One-Page Review of Must-Know Facts.
Is It Worth Pursuing?
Deciding whether to pursue this certification depends on your role, your unit's patient population, and your career goals within transplant or cellular therapy nursing. Because eligibility requires 2,000 hours of direct HSCT or cellular-therapy nursing experience, this isn't a credential nurses typically pursue early in their careers - it's built for nurses already embedded in transplant care who want formal recognition of that specialized expertise.
Before committing to the fee and preparation time, it's worth weighing the investment against your specific career trajectory. Is the BMTCN Certification Worth It?
