REx-PN or CPNRE: Comparing the Two Practical Nurse Licensing Exams by Province
A South African-trained enrolled nurse aiming for practical nurse registration in Canada will hit one question almost immediately: which exam am I actually going to sit? The REx-PN vs CPNRE licensing exam answer isn’t a matter of preference — it’s decided entirely by which province you’re heading to.
The front door is the same either way
Before either exam comes into the picture, the National Nursing Assessment Service handles the same intake step regardless of destination. NNAS processes a single application covering both the RN and LPN pathways under its expedited fee, so the comparison between the two exams only becomes relevant once your NNAS Advisory Report is in hand and you’re applying to a specific provincial regulator.
Where the REx-PN applies
Which provinces use REx PN exam requirements comes down to two: British Columbia, where it licenses LPNs, and Ontario, where the equivalent designation is RPN. The Regulatory Exam – Practical Nurse replaced the older exam in these two provinces back in January 2022, so if BC or Ontario is your target, this is the exam your preparation needs to be built around.
Where the CPNRE still runs
Everywhere else, the older exam remains the standard. Which provinces use CPNRE exam requirements is the longer list: Alberta, Saskatchewan, Manitoba, and the Atlantic provinces all still license through the Canadian Practical Nurse Registration Examination rather than the newer REx-PN. Neither exam is objectively harder or easier in the material sense — they’re simply the instrument each province’s regulator has chosen, and Canada hasn’t standardised on one nationally.
Why this matters more than it might seem to
LPN RPN exam differences by province matter for a very practical reason: your study materials, practice tests and exam-prep courses need to match the specific exam your target province actually uses. Preparing for the CPNRE when your realistic destination is Ontario, or vice versa, wastes time on content and format that won’t transfer directly to exam day.
The part nobody has mapped yet
One genuine gap worth flagging honestly: South Africa’s “enrolled nurse” and “staff nurse” categories don’t translate cleanly onto the Canadian LPN scope of practice, and no published table maps SA nursing categories directly against Canadian LPN or RPN designations. In practice, this means your NNAS Advisory Report — not a pre-existing equivalency chart — is what actually decides how your SA training and experience get classified going into either exam pathway.
Deciding which exam is yours
If British Columbia or Ontario is where you’re settling, prepare for the REx-PN. If you’re heading anywhere else in Canada, the CPNRE is almost certainly what you’ll sit. Either way, that decision follows your province choice — it doesn’t drive it — so settling on where you intend to live and work should come first, with exam preparation built around whichever regulator you land under.
Because your own NNAS outcome and provincial classification depend on your specific transcripts and work history, confirm the details with your target province’s regulator directly — and if your exam date has to be timed around a visa or PR milestone, a licensed RCIC is who to plan that with.
