The IELTS exam is especially useful for candidates who wish to either study in an English speaking country, or for those who need to prove their Engish level in order to get a visa.
Written by Cambridge English, it is seen as an alternative to the 'traditional' Cambridge exams due to its usefulness. Whilst 'Main Suite' Cambridge exams (FCE, CAE etc.) are useful to demonstrate your level of English proficiency in Europe, the IELTS exam is often recognised as the only acceptable proof for foreign governmental and pivate agencies.
IELTS is still uncommon in Spain as it is not normally required, but please contact us if you are unsure which examination to take.
