@Tutik, here's what it says about english requirements in ACT nomination:
from ACT nomination Guidelines
English language ability: You must either
♦ hold a passport from the United Kingdom; Canada; New Zealand; United States of America; Republic of Ireland;
or
♦ for all other passport holders, have a:
− current IELTS result with a minimum score 7 in speaking and 7 overall; or
− current OET result with a minimum grade B in all sections.
− If a higher level of English is an additional nomination condition on the SMP Occupation List: an IELTS result with the required English ability.
− if the occupation is verified as ‘limited’ or ‘off list’: an IELTS result with a minimum score of 8 in speaking and 8 overall is required.
ang required nila is minimum of 7.0 sa speaking, and 7.0 OBS NOT in each band..so it's not required na 7.0 ka sa lahat..but if you're aiming for additional points for IELTS you need get 7.0 sa lahat (S-R-W-L)..sa case mo OBS mo is 7.0, kaya lang sa speaking 6.5 ka
