What the CTP Credential Actually Is
CTP stands for Certified Transplant Preservationist. It is a professional certification administered by the American Board for Transplant Certification (ABTC) for people who work in organ preservation: the hands-on work of recovering organs from donors, preserving them, collecting specimens, and preparing organs for transport to the transplant center. In application and certification records you may also see the designation ROC-P.
Several unrelated credentials in other industries use the same three letters, including a well-known treasury credential. None of them has anything to do with this one. Everything on this page, and everything the exam tests, concerns the transplant preservation field. If you want a plain-language walkthrough of the acronym itself, see What Does CTP Stand For? or What Is CTP?, but keep in mind that this site covers only the ABTC credential.
The credential signals that you have demonstrated knowledge against an expert-established standard rather than simply logged hours on the job. For a field where errors in handling, labeling, or transport have real consequences, a third-party standard gives employers and colleagues a common reference point.
Who the Credential Fits
The CTP is built around people whose work touches organ preservation. The experience requirement is deliberately flexible: candidates need 12 months of organ-preservation work experience, and that work does not have to be the candidate's full-time responsibility. A supervisor must attest to the experience as an employee verification step.
That flexibility matters because preservation duties are spread across roles. Depending on the organization, the work may sit with recovery coordinators, preservation technicians, procurement staff, or clinicians who split their time across several responsibilities. If preservation is one slice of your week rather than the whole job, you can still qualify as long as you have accumulated the 12 months of qualifying work and can get it attested.
Employers in this space are typically organizations involved in organ recovery and transplant logistics. Because the exam spans recovery, preservation, specimens, and packaging for transport, it maps to the full chain of custody for an organ rather than a single step. For a closer look at the employment side, see CTP Jobs.
Exam Format and Question Style
The exam is computer-based and delivered at PSI test centers. It is closed book, calculators are prohibited, and you must present two forms of identification on test day.
| Feature | CTP Exam Detail |
|---|---|
| Total questions | 110 multiple choice |
| Scored items | 100 |
| Unscored pretest items | 10 |
| Time limit | Two hours |
| Answer options | Four options, one best answer |
| Delivery | PSI test centers, computer-based |
| Reference materials | Closed book; no calculators |
Two features of the format deserve attention. First, the ten unscored pretest items are mixed in with the scored ones and are not labeled, so you must treat every question as if it counts. Second, "one best answer" means that more than one option can look defensible; your job is to choose the option that most completely fits the scenario. Candidates who read for the first plausible answer tend to lose points to distractors that are partially correct.
Scoring is not based on passing each domain separately. Passing is determined by overall performance against ABTC's expert-established examination standard, and there is no published fixed percentage to aim for. For a deeper treatment, read CTP Passing Score 2026.
The Five Exam Domains
The ABTC Candidate Handbook (file dated August 13, 2026) contains the Examination Content Outline for the CTP. The five domain headings below are the official outline headings. The item counts come from summing the outline's recall, application, and analysis columns, so they are scored-item allocations, not issuer-published percentage weights.
Domain 1: Professional Practice (15 scored items)
The foundation domain covers the standards of conduct and responsibility that frame every technical task.
- Professional responsibilities and scope of the preservationist role
- Documentation habits that support traceability
- Communication within the recovery and transplant team
Domain 2: Organ Recovery (30 scored items)
The largest domain, and the one that deserves the most study hours.
- The recovery process from the preservationist's perspective
- Asepsis and maintaining a sterile field during recovery
- Handling organs correctly at the point of recovery
Domain 3: Organ Preservation (25 scored items)
The second-largest domain, focused on keeping organs viable between recovery and transplant.
- Preservation principles and the reasoning behind them
- Solutions and methods used to preserve organs
- Recognizing problems that threaten organ condition
Domain 4: Specimen Collection (12 scored items)
The smallest domain by item count, but one where precision matters.
- Which specimens accompany an organ and why
- Collection, labeling, and handling of specimens
- Keeping specimens matched to the correct donor and organ
Domain 5: Organ Labeling and Packaging for Transport (18 scored items)
The final link in the chain, where documentation and physical packaging come together.
- Labeling requirements and verification
- Packaging configuration for transport
- Transport considerations and handoff
Add the allocations (15 + 30 + 25 + 12 + 18) and you reach the 100 scored items. Organ Recovery and Organ Preservation together account for 55 of them, so more than half of your scored performance rides on those two domains. A full breakdown lives in CTP Exam Domains 2026: Complete Guide to All 5 Content Areas.
Eligibility, Fees and Scheduling Mechanics
Eligibility
The core requirement is 12 months of organ-preservation work experience, attested by a supervisor. The work need not be your full-time responsibility. The full prerequisite picture is covered in CTP Requirements 2026: Eligibility, Prerequisites & How to Qualify.
What an attempt costs
| Cost Item | Amount |
|---|---|
| Examination fee | $495 |
| Application fee | $150 |
| Total per attempt | $645 |
| International administration surcharge (if applicable) | $225 additional |
Fees are nonrefundable and apply again if you reapply, so a failed or missed attempt means paying the full amount a second time. That makes preparation before registration more economical than learning on the live exam. See CTP Certification Cost 2026: Complete Pricing Breakdown for the full cost picture, including renewal.
The 90-day windows
ABTC provides a 90-day examination-eligibility window once you are authorized to test. Here is a point where public instructions are not consistent: different sources describe the window as starting at payment, at application approval, or at eligibility confirmation. Do not assume those triggers are interchangeable. Follow the specific authorization dates issued to you, and if anything looks inconsistent, resolve it directly with ABTC or PSI before you schedule. For scheduling detail, see CTP Exam Dates 2026.
Retake rules
If you do not pass, retakes require a 90-day interval between attempts. After three unsuccessful attempts, you must complete 20 Category 1 CEPTCs before reapplying. Each reapplication carries the full fee again. These rules reward a deliberate approach: a third failed attempt triggers a substantial continuing-education requirement on top of the fees.
Key Takeaway
Treat your first attempt as the one you plan to pass. With a 90-day wait between attempts, nonrefundable fees, and a 20-CEPTC gate after three failures, a well-timed first sitting is cheaper in money and in months.
The 110-Versus-120 Question Conflict
If you research this exam online, you may run into two different question counts. The current ABTC handbook describes 110 questions: 100 scored plus 10 unscored pretest items. However, PSI's public online store lists an official self-assessment product whose description still refers to a 120-question certification exam.
These two sources conflict, and the handbook controls. The handbook is the issuer's current document, dated August 13, 2026, so plan around 110 questions in two hours. The store listing appears to carry older wording. If you see "120 questions" on a third-party site or a product page, treat it as outdated unless ABTC says otherwise.
Reading the Historical Pass Rate
ABTC's March 2025 statistical report records a 52% pass rate among 86 candidates for 2024. It is worth being precise about what that figure is and is not:
- It is a historical 2024 figure, not a 2026 rate.
- It is not a passing score. A 52% pass rate means roughly half of candidates passed; it does not mean you need 52% of questions correct.
- It is not documented as a first-attempt-only rate, so it may blend first-time and repeat candidates.
- The sample is small (86 candidates), so year-to-year swings are plausible.
The sensible interpretation is that the exam is a genuine screen: close to half of the people who sat for it in 2024 did not pass. That does not make it unreasonable, especially for candidates with solid hands-on experience who study the outline, but it does argue against walking in on experience alone.

Sequencing Your Study Around the Domains
Because the exam is closed book and scenario-driven, the most useful preparation anchors on the official outline rather than on generic review. One sensible way to order your time is by domain size and dependency, since recovery and preservation concepts feed directly into specimen handling and packaging questions.
Organ Recovery (30 items)
- Start here because it is the largest allocation
- Drill asepsis principles until you can explain the reasoning, not just the rule
Organ Preservation (25 items)
- Builds directly on recovery content
- Focus on why each preservation step exists and what goes wrong when it fails
Packaging/Transport and Specimens (30 items combined)
- Practice labeling and verification logic
- Review which specimens travel with which organ
Professional Practice and Mixed Review
- Cover the 15 professional-practice items
- Finish with timed mixed sets across all five domains
Whatever calendar you use, rehearse the actual constraints: 110 questions, two hours, no notes, no calculator, four options with one best answer. Practice questions should be original study material, not copies of protected exam items. You can try CTP-style practice on the main practice test site, and the CTP Study Guide 2026 walks through a fuller plan. For a quick fact review the night before, the CTP Cheat Sheet condenses the essentials.
Renewal and Keeping the Credential
Certification is valid for three years. To renew, you have two paths: successful re-examination, or earning 60 CEPTCs (continuing education points), including at least 20 Category 1 and 10 Category 2 points. The renewal fee for a single certification is $395.
| Renewal Element | Requirement |
|---|---|
| Certification period | Three years |
| Total CEPTCs | 60 |
| Minimum Category 1 | 20 |
| Minimum Category 2 | 10 |
| Alternative | Successful re-examination |
| Fee (single certification) | $395 |
The practical lesson is to start collecting CEPTCs early in the cycle instead of scrambling in year three. Keep records of each activity as you go. Official details are on ABTC's recertification pages, which are the authority if requirements change.
Career Value Without Assuming a Pay Premium
It is tempting to frame certification purely as a salary play, but there is no basis here to promise a pay premium for holding the CTP, and this article makes none. A fairer way to weigh the decision is to compare the real costs ($645 per attempt, possible international surcharge, $395 per renewal cycle, and the study time) against benefits that are easier to verify: a recognized standard of competence, credibility with colleagues and employers, and a structured reason to keep your knowledge current through continuing education.
Whether those benefits justify the cost depends on your employer, whether your organization reimburses fees, and your own career plans. For a structured way to think it through, see Is the CTP Certification Worth It? and the CTP Salary Guide, which treats earnings qualitatively. When you are ready to begin, start with the CTP practice questions and work through your weakest domain first.
