If you are an Indian nurse targeting NMC registration, choosing between OET and IELTS is one of your earliest and most consequential decisions. Both tests are accepted, but they differ in format, cost, difficulty level, and score combining rules. This guide compares them specifically through the lens of NMC registration — not general use — so you can make an informed choice.
NMC Score Requirements: Side by Side
The most important difference here is Writing. The NMC accepts OET Grade C+ (300+) in Writing, which is significantly more lenient than the IELTS requirement of 7.0. Writing is the sub-test where Indian nurses most commonly fall short in IELTS, so this lower threshold is a major advantage for OET candidates.
Score Combining: A Lifeline in Both Tests
The NMC allows you to combine your best sub-test scores from two sittings taken within six months for both OET and IELTS. The rules are:
- OET: Each individual sitting must have no sub-test below Grade C (200). You can then combine your best results across two sittings.
- IELTS: Each individual sitting must have no sub-test below 6.5. You combine your best results from two sittings within six months.
Score combining is valuable if you consistently achieve the required score in three sub-tests but struggle with one. However, it doubles your exam costs, so weigh this against additional preparation.
Why Most Indian Nurses Find OET Easier
Clinical Content Advantage
Every OET section uses healthcare scenarios. The listening section features patient consultations. The reading passages cover hospital policies, clinical research, and patient information leaflets. The writing task is a referral letter — something you may already write at work. The speaking test is a patient role-play. For a working nurse, this content is far more intuitive than IELTS topics like urbanisation, space exploration, or the economics of tourism.

Writing: Letter vs Essay
This is where the gap is most dramatic. OET requires a 180-to-200-word referral letter based on clinical case notes — a structured, professional task with a clear format. IELTS requires a Task 1 graph/chart description and a Task 2 argumentative essay on an abstract topic. Many Indian nurses who score OET Grade B in Writing struggle to reach IELTS 7.0 because the essay format requires a completely different skill set.
Speaking: Role-Play vs Interview
OET speaking is a five-minute patient consultation — taking a history, explaining a procedure, or counselling an anxious patient. This feels natural for working nurses. IELTS speaking is a general interview where you discuss topics like travel, technology, or childhood memories. The clinical role-play format gives nurses a built-in advantage.
Where IELTS Has the Edge
Cost
IELTS costs approximately USD 255 compared to OET's USD 587. If you are on a tight budget and need to attempt the test multiple times, IELTS is significantly cheaper per sitting.
Accessibility
IELTS has over 200 test centres across India. OET has approximately 15. If you live in a Tier 2 or Tier 3 city, you may need to travel for OET. However, OET@Home (remote proctored) eliminates this barrier entirely.
Speed of Results
IELTS results are available in 3 to 5 days. OET results take 16 business days. If you are working against a recruitment deadline, IELTS gives you faster turnaround.
Immigration Dual Use
If you need an English test score for both NMC registration and your UK visa application, IELTS is accepted for both. OET is accepted for NMC registration but not by UKVI for immigration purposes. Some nurses take OET for NMC registration and then need a separate IELTS for their visa — check with your recruiter whether this applies to your specific visa pathway.
Decision Framework
Choose OET if: you are a working nurse with reasonable clinical English, you want the content advantage in Writing and Speaking, and you are comfortable with the higher cost. The lower Writing threshold (C+ vs 7.0) alone makes OET the smarter choice for most Indian nurses.

Choose IELTS if: you are on a tight budget, you live far from an OET centre and do not want to take OET@Home, your general English is already strong across all four skills, or you need a single score for both registration and immigration.
The pragmatic approach: Attempt OET first. The pass rate for nurses is higher, and the clinical content gives you a natural advantage. If you do not achieve Grade B after two attempts, switch to IELTS — the skills are transferable, and you may find the format suits you better.
What Indian Nurses Actually Do
In practice, the majority of Indian nurses targeting the UK now choose OET. The combination of familiar content, the lower writing threshold, and the score combining option makes it the path of least resistance. Recruitment agencies report higher first-attempt pass rates among OET candidates compared to IELTS, particularly in the Writing sub-test. The higher cost is a real consideration, but if OET helps you pass on the first or second attempt rather than retaking IELTS three or four times, it saves money in the long run.
