REx-PN Exam Guide: What Ontario and BC Practical Nursing Candidates Need to Know

Quiz REx-PN Practice Questions

Understanding the Path to Practical Nurse Licensure

The REx-PN is the computer-adaptive regulatory exam, developed by NCSBN, that Ontario and British Columbia use to license practical nurses, having replaced the CPNRE in these provinces since 2022. This guide covers eligibility, registration and fees, the exam format, scoring, and how to prepare.

What Is the REx-PN Exam?

If you’re on the path to becoming a Registered Practical Nurse (RPN) in Ontario or a Licensed Practical Nurse (LPN) in British Columbia, the REx-PN is the regulatory exam standing between you and your practising licence. REx-PN stands for Regulatory Exam – Practical Nurse. It’s a standardized, computer-adaptive test developed by the National Council of State Boards of Nursing (NCSBN), the same organization behind the well-known NCLEX exams for registered nurses in the United States and Canada.

Since January 2022, the REx-PN has been the exam used in Ontario and British Columbia to assess whether practical nursing graduates have the entry-level competencies needed to practise safely. It replaced the Canadian Practical Nurse Registration Examination (CPNRE) in these two provinces, though the CPNRE continues to be used by regulators in other parts of Canada. If you trained or plan to register outside Ontario or BC, it’s worth double-checking with your own provincial regulator which exam currently applies to you, since requirements can differ and do change over time.

Who Administers It, and What’s the Legal Basis

In Ontario, the College of Nurses of Ontario (CNO) is the regulatory body responsible for licensing RPNs and determining who is eligible to write the exam. In British Columbia, that role belongs to the BC College of Nurses and Midwives (BCCNM). Both colleges operate under provincial health profession legislation that gives them the authority to set registration requirements, including successful completion of a recognized licensure exam, as a condition of practising as a practical nurse.

While CNO and BCCNM determine eligibility and ultimately grant (or deny) registration, the exam itself is developed by NCSBN and delivered through Pearson VUE testing centres under an agreement with Pearson Professional Assessments. In practice, this means your relationship with your college and your relationship with Pearson are two separate, sequential processes: the college first confirms you’re eligible to test, and only then does Pearson handle your actual exam registration and scheduling.

Eligibility Requirements

To sit the REx-PN, you generally need to have completed (or be nearing completion of) an approved practical nursing education program and applied for registration with CNO or BCCNM. The college will review your education, any out-of-country credentials if applicable, and other registration criteria, such as background and language requirements, before declaring you eligible to test. Only after your college confirms eligibility will you receive instructions to register with Pearson VUE. Because eligibility rules can vary depending on your specific education path and situation, your best source of truth is always the current guidance published directly by CNO or BCCNM for your province.

Registration Process and Fees

Once you’re deemed eligible, you’ll register for the exam through Pearson VUE and pay the exam fee directly to Pearson. This fee is separate from, and in addition to, any application or registration fees you pay to your college. The exam fee has been reported in the range of a few hundred dollars plus applicable tax, but fees can change, so it’s wise to confirm the current amount on the official Pearson VUE or college pages before you pay anything.

After registering, you’ll receive an Authorization to Test (ATT), which has a limited validity window, commonly around 90 days. You’ll need to schedule and sit your exam within that window, or your registration may expire and require you to start the registration and payment process again. Plan your study timeline with that window in mind so you’re not rushing to prepare at the last minute or, conversely, letting your ATT lapse unused.

Exam Format: What to Expect on Test Day

The REx-PN is a computer-adaptive test (CAT), meaning the difficulty of each question adjusts in real time based on how you’re answering. Get a question right, and the next one tends to be a bit more challenging; struggle, and the system recalibrates. This adaptive approach is designed to pinpoint your competency level efficiently rather than asking everyone the exact same fixed set of questions.

Most candidates can expect somewhere between 90 and 150 scored items, with a maximum appointment length of around four hours to account for a tutorial, breaks, and the variable number of questions the adaptive algorithm delivers. Content spans the scope of practical nursing practice, including patient care, safety, infection control, pharmacology basics, and nursing judgment in realistic clinical scenarios, often presented as case-based or situational questions rather than simple recall.

How the Exam Is Scored, and What Happens If You Don’t Pass

The REx-PN uses a pass/fail model based on a predetermined competency standard rather than a percentage score. Because it’s adaptive, two candidates can answer a different number of questions and still both pass, since the algorithm is measuring ability relative to the standard, not just counting correct answers.

If you don’t pass on your first attempt, know that it’s not the end of the road. Candidates are generally allowed to retake the exam, typically after waiting a set period (often cited as around 60 days) before rewriting, and there’s no indication of a lifetime cap on attempts. That said, repeating the registration and fee process each time is a real cost in money and time, which is exactly why solid preparation before your first sitting pays off.

How to Prepare

A few practical habits can make a meaningful difference:

• Practise with realistic, scenario-based questions. Because the REx-PN leans heavily on applied clinical judgment rather than simple fact recall, working through practice questions that mirror that computer-adaptive, situational style helps you get comfortable with the format itself, not just the content.
• Review core clinical areas systematically. Patient safety, infection prevention, medication administration principles, and prioritization of care are recurring themes worth revisiting deliberately rather than passively rereading notes.
• Simulate real exam conditions. Since the real test can run up to four hours, practising focus and pacing under timed, distraction-free conditions builds the stamina the actual appointment demands.
• Confirm the logistics early. Know your ATT expiry date, your testing centre location or remote-proctoring requirements, and what identification you’ll need, so none of that becomes a last-minute stressor.
• Lean on your program’s resources too. Your nursing instructors and clinical placements have already exposed you to much of this content in context; connecting practice questions back to real patient scenarios you’ve seen often makes the material stick.

Final Thoughts

The REx-PN is a significant milestone, but it’s a well-defined one: a computer-adaptive exam built around realistic nursing judgment, administered through a clear sequence of college eligibility review, Pearson VUE registration, and scheduled testing. Understanding exactly how that process works, and giving yourself structured, scenario-based practice ahead of time, puts you in the strongest position to walk into your appointment with confidence rather than guesswork.
