'International English Language Testing System' (IELTS, pronounced /'aıjelts/) is a test of English language proficiency. It is jointly managed by University of Cambridge ESOL Examinations, British Council and IDP Education Australia. Candidates may choose either the Academic Module or the General Training Module:

• The Academic Module is intended for those who wish to enroll in universities and other institutions of higher education.
• The General Training Module is intended for those planning to undertake non-academic training or to gain work experience, or for immigration purposes.

IELTS is accepted by most Australian, British, Canadian, Irish, New Zealand and South African academic institutions, by an increasing number of academic institutions in the USA, and by various professional organizations. It is also a requirement for migration to Australia, Canada, New Zealand, and many other countries.
