If you are finishing a Practical Nursing program in Ontario or British Columbia, the REx-PN is the final gate between you and your nursing licence. This guide explains exactly what the exam is, how its adaptive format works, what content it covers, and how to build a study plan that actually gets you to a pass.
REx-PN stands for Regulatory Exam – Practical Nurse. It is the entry-to-practice exam for practical nurses in Ontario and British Columbia, administered through the provincial nursing regulators (in Ontario, that is the College of Nurses of Ontario, or CNO).
The exam was developed specifically for Canadian practical nursing practice. That matters: unlike older exams borrowed from other countries, the REx-PN tests the competencies, standards, and clinical realities of working as a practical nurse in Canada — including Canadian legislation, ethics, and scope of practice.
You cannot practise as an RPN until you meet all registration requirements, and passing the REx-PN is one of the central ones. Always confirm the current list of requirements directly with your provincial regulator, because policies can change.
REx-PN uses CAT – computerized adaptive testing. Instead of giving every candidate the same fixed set of questions, the computer adapts to you:
In practical terms, the exam typically runs somewhere around 90 to 150 questions with a time limit of up to about four hours. Treat those numbers as approximate — confirm the current figures with the CNO before your exam date.
The REx-PN is built from the entry-level competencies expected of a new practical nurse. The content falls into four broad areas — the same framework used across Canadian practical nursing exams:
Management of care (delegation, prioritization, referrals, continuity of care) and safety/infection control (standard precautions, error prevention, safe use of equipment). This is heavily tested because it is what keeps patients alive on your first day of work.
Growth and development across the lifespan, disease prevention, health screening, and teaching clients about healthy behaviours. Expect questions on immunizations, prenatal care, and health teaching for chronic conditions.
Mental health, therapeutic communication, crisis intervention, cultural humility, grief and loss, and supporting clients through stressful health events. Communication questions are classic “best answer” items — always choose the most therapeutic, client-centred response.
The largest area: basic care and comfort, pharmacological therapies (medication administration, side effects, the rights of medication safety), reduction of risk potential (assessments, lab values, recognizing deterioration), and physiological adaptation (managing acute and chronic conditions across body systems).
The exam typically ranges from around 90 to 150 questions, with up to about four hours of testing time, because the adaptive format stops when the computer has enough information. Confirm current numbers with the CNO, as they can change.
The REx-PN is criterion-referenced: the computer decides whether your demonstrated ability is above or below the passing standard. There is no fixed percentage like “70%” — it is about consistently performing above the competency threshold across the exam.
No. The NCLEX-PN is the American exam for practical/vocational nurses in the United States. The REx-PN is the Canadian exam for practical nurses in Ontario and BC, built around Canadian competencies and legislation. They are different exams — I compare them in detail in my REx-PN vs NCLEX guide.
Regulators generally allow rewrites, but limits, waiting periods, and fees vary — check the CNO’s current exam policy for the exact rules. The best strategy is simple: prepare thoroughly the first time so you never need to find out.
