IELTS isn't one single test for immigration purposes — the version, the minimum bands, and even whether two sittings can be combined all depend on exactly which pathway you're applying through. Rules also change; always verify against the official source before you book.
The single most common mistake is booking "IELTS Academic" or "IELTS General Training" without checking whether the receiving body specifically needs the UKVI-approved version — a UK Home Office requirement for certain visa categories that must be taken at a UKVI-approved centre, even though the test content itself is identical to standard IELTS.
IELTS for UKVI (Academic or General Training) is the same exam, same format, same marking — the difference is administrative: it's taken at a centre approved for UK Home Office visa purposes and the Test Report Form is recognised for those specific visa categories. If your visa category requires the UKVI version specifically, a standard IELTS certificate — even with an identical score — will not be accepted. Always check your exact visa category's current requirement on the official UK government site before booking.
Nurses and midwives registering with the UK's Nursing and Midwifery Council are commonly required to meet a high overall band with a specific per-skill minimum, and NMC has in the past allowed scores to be combined across two sittings within a defined window rather than requiring every skill to be met on a single attempt. OET is also commonly accepted as an alternative to IELTS for this pathway. Requirements and the combining-of-sittings policy have changed over time — confirm the current NMC English language requirements directly on the NMC website before planning your test date.
Canada's Express Entry system uses IELTS General Training scores (not Academic) converted to Canadian Language Benchmark (CLB) levels, which then feed into your Comprehensive Ranking System (CRS) points. Higher CLB levels earn more points, and specific programs may set their own minimum CLB thresholds. IRCC publishes and periodically updates its own IELTS-to-CLB conversion table — treat any table you see elsewhere, including general guidance here, as a starting point only, and confirm current thresholds on the IRCC website.
Australian skilled migration visa categories set their own minimum IELTS bands (commonly assessed via the Academic or General Training version depending on the visa stream). Health professionals registering through AHPRA (the body covering nursing, medicine, and allied health) generally face a stricter requirement than general skilled migration — often a high band with no individual skill falling below a set minimum, assessed on a single test sitting rather than combined across attempts, though the exact rule can differ from NMC's. Confirm current AHPRA English-language requirements directly on the AHPRA website for your specific profession.
