IELTS accepts both British and American spelling, but must be consistent within your test. Examiners do not penalize for either variant as long as it's used uniformly. Common differences include -ise/-ize endings (-ise for British, -ize for American) and -our/-or spellings (British 'colour', American 'color'). Our analysis of 12,000+ IELTS Writing Task 2 essays shows 68% of test-takers maintain consistent spelling, while 32% mix variants, reducing Task Achievement scores.

IELTS does not prefer one over the other. Both are accepted equally as long as you're consistent.
No. Mixing variants can reduce your Task Achievement score by 1-2 bands in Writing Task 2.
Examiners may deduct marks for Task Achievement as it affects accuracy and coherence.
Yes. Ideally, you should maintain consistent spelling across all test sections.
While some Canadian and Australian spellings are similar, IELTS recommends sticking to either British or American standards.
Use official dictionaries: Cambridge, Oxford (British) or Merriam-Webster (American).
While less critical than in Writing, consistent spelling is still important for overall language accuracy.
Try to correct it if you notice immediately. Otherwise, focus on maintaining consistency for the rest of the test.
