CTP Requirements 2026: Eligibility, Prerequisites & How to Qualify

Which CTP This Article Covers

Before anything else, a note on identity. In this article, CTP means Certified Transplant Preservationist, the credential administered by the American Board for Transplant Certification (ABTC). Several unrelated credentials in other fields share the same three letters, and their eligibility rules, fees, and exam formats have nothing to do with this one. Everything below applies only to the ABTC transplant credential, whose exam is delivered through PSI and appears in certification records under the ROC-P designation.

If you are still orienting yourself, our explainers on what CTP certification is and what CTP stands for cover the basics. This guide focuses on one question: do you qualify, and what does qualifying actually involve?

The Core Eligibility Rule: 12 Months of Preservation Work

The central requirement for the Certified Transplant Preservationist exam is 12 months of organ-preservation work experience. Two details in how ABTC frames this matter a great deal to real candidates:

• It need not be your full-time responsibility. Many people who handle preservation tasks do so alongside other duties, such as organ recovery coordination, procurement logistics, or laboratory work. Preservation does not have to be the entire job description for the time to count.
• It must be verifiable. Experience is supported by an employee attestation from a supervisor, so the work needs to be something your employer can speak to.

Because the exam spans recovery, preservation, specimen collection, and packaging, candidates with a broad exposure to the donor-to-transport pathway tend to find the content outline more familiar than those whose work is narrowly specialized. We discuss that in our CTP difficulty guide.

Supervisor Attestation and Documentation

The attestation requirement is easy to underestimate. A few practical points:

1. Identify your attester early. This is typically a direct supervisor or someone in your organization positioned to confirm your preservation work and its duration.
2. Make the 12-month tally precise. Know your start date in preservation-related duties and be ready to describe the nature of the work.
3. Confirm the current form and process on the ABTC site. Application mechanics can change, and the authoritative source is ABTC's certification examinations page rather than any third-party summary, including this one.

If you are between employers, a recent job change is the most common complication. Plan for how you will obtain an attestation covering prior experience, since a former supervisor may be harder to reach than a current one.

Fees and Application Mechanics

Qualifying also means paying, and the fee structure has features worth understanding up front. The table summarizes the per-attempt cost.

The two features that catch candidates off guard are that fees are nonrefundable and that they apply again to reapplications. A failed attempt or a missed testing window means paying the full amount a second time. For a deeper budget view, including practice-material costs and renewal, see our complete CTP certification cost breakdown.

The 90-Day Examination Window

Once you are approved, ABTC provides a 90-day examination-eligibility window in which to sit the exam. That much is straightforward. What is less straightforward is exactly when the clock starts.

Public instructions describe the starting point inconsistently. Depending on where you read, the window appears to begin at payment, at application approval, or at eligibility confirmation. These are not interchangeable triggers, and the difference can matter if you are scheduling near the edge of the window.

What You Qualify to Sit: The Exam Format

Meeting the requirements gets you access to a specific test, so it helps to know what it looks like:

• 110 multiple-choice questions: 100 scored and 10 unscored pretest items.
• Two-hour time limit.
• Four answer options per question, with one best answer.
• Computer-based delivery at PSI test centers.
• Closed book, with calculators prohibited.
• Two forms of identification required at check-in.

The 110-Versus-120 Question Discrepancy

You may encounter a conflicting number. PSI's public store listing for the official self-assessment still describes a 120-question certification exam, while the current ABTC Candidate Handbook, dated August 13, 2026, specifies 110 questions. The handbook controls the live exam count, so plan around 110, and treat the PSI listing as stale wording on a product page. If the discrepancy worries you, confirm with ABTC.

On scoring, ABTC measures overall performance against an expert-established standard rather than requiring separate passes by domain, and it does not publish a fixed numeric passing mark. Anyone quoting a precise cut score is not drawing it from an issuer source. We unpack this in our CTP passing score article.

Five Domains That Shape Your Preparation

The ABTC examination content outline (Candidate Handbook, PDF pages 39-40) organizes the exam into five domains. Summing the outline's recall, application, and analysis columns gives these scored-item allocations, which are counts out of 100 scored items rather than issuer-published percentage weights:

Organ Recovery is the heaviest at 30 scored items, followed by Organ Preservation at 25. Together they account for more than half the scored content, which tells you where a candidate with limited prep time should concentrate. The full breakdown is in our CTP exam domains guide.

Educational scope note: This article and the exam-prep materials built around it support examination review. They are not clinical instructions, and anyone applying preservation concepts in practice should verify current clinical policies and protocols at their own organization.

Retake Rules and the Three-Attempt Threshold

Qualifying is not a one-time event if the first attempt does not go your way. The retake rules are specific:

• A 90-day interval is required between attempts.
• After three unsuccessful attempts, you must complete 20 Category 1 CEPTCs (continuing education points) before you can reapply.
• Each reapplication carries the $645 cost again.

The historical context matters for setting expectations. ABTC's March 2025 statistical report recorded a 52% pass rate among 86 candidates for 2024. Read that carefully: it is a historical figure for one year, not a 2026 rate, not a passing score, and not a documented first-attempt-only number. It suggests the exam is genuinely selective without telling you your personal odds. For fuller interpretation, see our CTP pass rate analysis.

After You Qualify: Preparation Sequencing

With a 90-day window and a 90-day retake interval, timing your preparation is a practical decision, not an academic one. One approach that fits the domain allocations:

Adjust this to your window, since a 90-day authorization leaves little slack for a lengthy plan. Our CTP study guide expands on resources and routines, and the CTP cheat sheet is useful for last-week review. PSI also lists an official $60 self-assessment (30 questions, 60-day access, one scored attempt), which can serve as a calibration check, though we reviewed only the public listing, not the paid question bank. You can also try our CTP practice tests for original practice questions that are not represented as protected exam items.

Keeping the Credential: Three-Year Renewal

Qualification does not end at passing. The Certified Transplant Preservationist credential is valid for three years. To renew, you have two paths:

• Earn 60 CEPTCs, including at least 20 Category 1 and 10 Category 2 points, or
• Pass the exam again (re-examination).

The single-certification renewal fee is $395. Because the continuing-education route is spread across three years, it rewards candidates who track points from the beginning rather than scrambling near the deadline. Authoritative details live on ABTC's recertification pages, which are the place to verify requirements as they change.

Who Benefits From the Credential

The people who realistically pursue this credential work in the organ donation and transplant ecosystem: organ procurement organizations, recovery and preservation teams, and transplant programs where preservation and transport handling are part of the job. Our CTP jobs overview covers where these roles sit.

On compensation, be cautious. We do not assume the certification carries a pay premium, and nothing in the ABTC materials we reviewed promises one. Whether the credential is worth the fees and effort depends on your employer's expectations, your career path, and any recognition or advancement it supports. We work through that reasoning without inflated claims in our ROI analysis and our salary guide.
