Nurses sitting English exams, as part of their skills assessment, have three options:
Academic IELTS , minimum Band 7 in all 4 sections : https://takeielts.britishcouncil.org/choose
Pearson PTE, 65+ in all 4 Communicative Skills: https://pearsonpte.com/
Occupational English Test: https://www.occupationalenglishtest.org/
After achieving the necessary scores for this purpose, it is sometimes then necessary to either resit Pearson PTE or switch IELTS module, from Academic to General, to score minimum Band 8, in IELTS, or 79+ in PTE, for visa application purposes.
