- PBSE is Part I of the ABCP's Certified Clinical Perfusionist process; passing it alone does not award CCP.
- Training must be completed through an accredited perfusion program before you sit the exam.
- All 11 knowledge-base domains may be tested, and PBSE emphasizes basic-science processes over application.
- The exam has roughly 220 multiple-choice items with a four-hour limit; passing is 400 on a 120-480 scale.
What "PBSE Training" Actually Means
The Perfusion Basic Science Examination (PBSE) is administered by the American Board of Cardiovascular Perfusion (ABCP). It is the first of two examinations on the path to the Certified Clinical Perfusionist (CCP) credential; the second, CAPE, is a separate examination with its own four-hour timer. Because of that structure, "PBSE training" is not a short course you buy and finish. It is the combination of formal perfusion education, supervised clinical cases, and targeted exam review that qualifies and prepares a candidate to sit Part I.
If you are still orienting yourself to the credential, the overview at What Is PBSE Certification? covers the basics. This article focuses on the training side: what you need to have completed, what the exam expects you to know, and how to organize your preparation around the official scope.
The Training Gate: Eligibility and Case Records
Before any exam-focused review begins, the ABCP requires a documented training foundation. Candidates normally need graduation from an accredited perfusion program before testing, plus an official graduation transcript, a school clinical-competency statement, and a documented case record. You may apply while still enrolled, provided graduation precedes the examination date. Limited historic exceptions exist for pre-April 15, 1981 entrants and previously certified perfusionists, but they do not apply to most current candidates.
The detailed guidebook criteria are specific, and they take precedence over simplified "75 CPB" wording you may see on the main PBSE page:
- At least 75 qualifying primary clinical perfusion activities.
- Within that total, five qualifying 3P ECMO or 6P VAD cases and at least 70 primary CPB cases.
- At least 10 pediatric CPB cases, performed or observed. Performed pediatric cases may overlap the 75, but observed cases cannot count toward the 75.
- Cases must occur in the US, its territories, or Canada.
- An ABCP-certified CCP instructor must be physically present during CPB cases.
A full walkthrough of these prerequisites is in PBSE Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Mapping Your Training to the 11 Exam Domains
The ABCP's examination knowledge base contains 11 content areas shared by PBSE and CAPE. These are official knowledge-base headings, not a study curriculum invented by a prep provider. All of them may be tested on PBSE; the difference is emphasis. PBSE leans toward basic-science processes (why something happens physiologically, pharmacologically, or mechanically), while CAPE leans toward application. The ABCP has not verified an official percentage distribution across the domains here, so no single domain should be treated as the largest-weighted one.
| Domain | Where it typically shows up in training |
|---|---|
| 1. Anatomy & Physiology | Foundational coursework; cardiac, pulmonary, renal and hemostatic physiology |
| 2. Pharmacology | Drug classes used during bypass, anticoagulation, cardioplegia concepts |
| 3. Pathology | Cardiac and vascular disease states that drive surgical indications |
| 4. Laboratory Analysis | Blood gas, coagulation and chemistry interpretation |
| 5. Quality Assurance | Documentation, protocols, safety systems, outcome tracking |
| 6. Devices & Equipment | Pumps, oxygenators, circuits, monitors, heat exchangers |
| 7. Clinical Management | Conduct of bypass, physiologic goals, perfusion strategy |
| 8. Special Patient Groups | Pediatric, neonatal and other altered-physiology populations |
| 9. Special Procedures/Special Techniques | Procedures and techniques beyond routine adult bypass |
| 10. Catastrophic Events & Device Failure | Recognition and response to emergencies and equipment failure |
| 11. Monitoring | Hemodynamic, temperature, oxygenation and other monitored parameters |
A detailed breakdown of each heading is available in PBSE Exam Domains 2026: Complete Guide to All 11 Content Areas.
How the Exam Delivers Questions
Knowing the delivery format shapes how you train, because it determines how you should practice under time pressure.
- Format: approximately 220 multiple-choice items. The count is approximate and should not be treated as an exact number.
- Time: a four-hour testing limit.
- Delivery: Pearson VUE test centers, with Professional Testing, Inc. (PTI) supporting development and administration.
- Identification: bring matching, original, unexpired government-issued photo ID.
- Blocks (Fall 2026 onward): items are delivered in blocks, and you cannot return to a block once it is submitted. Total testing time and approximate item count are unchanged. No official block size has been stated.
Key Takeaway
Because submitted blocks are locked, train yourself to commit to an answer and move on. Habits like leaving dozens of items flagged to revisit at the end no longer work under block delivery.
Where Classroom Training Meets Exam Content
Because PBSE emphasizes basic-science processes, the most productive review revisits the "why" behind everyday clinical routines. The blocks below highlight how coursework themes connect to testable material. They are illustrative of the subject matter, not a prediction of specific questions.
Anatomy & Physiology
Expect to reason from mechanisms, not recite lists.
- How cardiopulmonary bypass alters normal circulatory and gas-exchange physiology
- Hemostasis and the effects of anticoagulation on coagulation pathways
- Regional blood flow and organ perfusion concepts
Pharmacology
Know drug actions and the reasoning behind their use, not only names.
- Mechanism and reversal of anticoagulants used during bypass
- Vasoactive and cardioprotective agents and their physiologic effects
- Interactions between pharmacologic agents and the extracorporeal circuit
Laboratory Analysis
Interpret data and understand what drives it.
- Arterial and venous blood gas interpretation
- Coagulation testing principles and what results imply
- How dilution and temperature change measured values
Devices & Equipment
Principles behind the hardware are fair game.
- Oxygenator and heat-exchanger function at a conceptual level
- Pump mechanics and the physics of flow and pressure in a circuit
- Safety features and monitoring components of the extracorporeal system
Catastrophic Events & Device Failure
Recognition and response logic, grounded in underlying principles.
- Identifying the physiologic and mechanical signature of a developing problem
- Reasoning through immediate priorities when equipment or patient status changes

Official Practice Exams and Block Training
The ABCP has relaunched its official practice exams. Public descriptions indicate they use block format, approximately half-length timing, domain feedback, and online calculator and whiteboard features. These descriptions apply to the practice product; they should not be assumed to describe the actual-exam calculator policy, which this article does not treat as separately verified. Confirm testing-day rules directly with the ABCP and Pearson VUE.
For supplemental question-style practice under timed, block-like conditions, you can also work through the PBSE practice tests on this site. Use domain-level feedback, from official or third-party tools, to direct your review toward weaker areas rather than rereading everything equally.
Sequencing Your Final Months
Generic study methods matter less than ordering your review around the official scope. One reasonable approach is to front-load the domains that other domains depend on, then layer in applied and emergency content. The sample sequence below is a suggestion, not an ABCP requirement.
Foundations
- Anatomy & Physiology and Pathology, since later domains build on these
- Pharmacology, tied to the physiology you just reviewed
Measurement and Hardware
- Laboratory Analysis and Monitoring, practicing interpretation
- Devices & Equipment and Quality Assurance
Application-Adjacent Content
- Clinical Management and Special Patient Groups
- Special Procedures/Special Techniques
Integration
- Catastrophic Events & Device Failure reasoning
- Full-length timed practice in block format, then targeted remediation

Fees, Windows and Deadlines
Planning training around the calendar and budget prevents last-minute surprises.
| Item | Detail |
|---|---|
| PBSE fee | USD 360 |
| Late-application fee | USD 100, when applicable |
| Refunds | Published no-refund policy applies |
| Passing scaled score | 400 on a 120-480 scale, criterion-referenced |
| Results | Preliminary pass/fail at the test center; final verified results within six weeks |
| Attempts | Unlimited, once per examination window; state licensure limits may separately apply |
On timing, the current ABCP calendar lists October 20-24, 2026 for the fall window, which takes precedence over the October 21-24 dates in the older 2025 Annual Report. Applications for that window closed October 5, 2026, with a late fee after September 21, so the fall window is no longer open to new applicants. Regular spring and fall windows continue. The January and July 2027 pilot windows are limited to eligible retesting candidates and qualifying CAPE holdovers who already have prior-window applications on file; they are not open to unrestricted new PBSE applicants.
More detail is available in PBSE Certification Cost 2026: Complete Pricing Breakdown and PBSE Exam Dates 2026: Testing Windows, Deadlines & Scheduling. The scoring standard is explained in PBSE Passing Score 2026: Exactly What You Need to Pass.
What Training Leads To After PBSE
Passing PBSE moves you to the second examination, CAPE, which has its own separate four-hour timer and emphasizes application. Once both are passed, the CCP credential is awarded. At that point maintenance requirements begin; these are CCP obligations, not additional PBSE content domains.
- Standard maintenance: 40 clinical activities annually, including at least 25 primary and no more than 15 secondary, plus 45 CEUs per three-year cycle, with at least 15 Category I CEUs.
- New CCPs certified in the fall: the first reporting cycle requires 20 activities, including at least 13 primary and no more than seven secondary, before the standard 40 resumes. Professional-activity CEU requirements are not prorated.
- Reporting periods end June 30, with reports due July 31.
These figures follow the live ABCP recertification pages. A separate Booklet of Information shows conflicting edition versions (a 2026 version 2.0 parsed copy and a 2025 version 1.2 rendered copy), so rely on the current recertification pages and confirm with the ABCP before planning around them.
On the career side, no PBSE-specific salary premium has been verified. Perfusionist pay depends on the occupation, call pay, and the training investment, with CCP certification as a later milestone.

Frequently Asked Questions
You may apply while still enrolled, but graduation must occur before the examination date. Normal eligibility also requires an official graduation transcript, a school clinical-competency statement, and a documented case record.
The detailed guidebook criteria call for at least 75 qualifying primary clinical perfusion activities, including five ECMO or VAD cases and at least 70 primary CPB cases, plus at least 10 pediatric CPB cases performed or observed. Observed pediatric cases do not count toward the 75.
No. All 11 knowledge-base domains may be tested on PBSE, and no official percentage distribution has been verified, so you should not assume any domain is the largest or the safest to skip.
A scaled score of 400 on a 120-480 scale, using a criterion-referenced standard. It is not a grading curve, and no raw-percentage rule is published.
The ABCP permits unlimited attempts, once per examination window. Separate state licensure rules may impose their own attempt limits, so check with your state if that applies to you.
