IELTS — the International English Language Testing System — is one of the world's most widely accepted English proficiency tests, used by universities, employers, professional registration bodies, and immigration authorities in dozens of countries. If you're encountering it for the first time, the format and terminology can be confusing. This guide covers the basics: what IELTS actually tests, who administers it, and how scoring works.
Who administers IELTS?
IELTS is jointly owned and administered by the British Council, IDP: IELTS Australia, and Cambridge Assessment English. In most countries, you can register through either the British Council or IDP (Cambridge Assessment English generally does not handle candidate registration directly) — both deliver the exact same test, scored to the same standard, so your choice between them usually comes down to which has a more convenient test centre or date near you, not which is 'better' or more widely recognised.
Academic vs. General Training
IELTS comes in two versions, and choosing the right one matters. IELTS Academic is for candidates applying to study at university level or seeking professional registration in an English-speaking country — its Reading passages and Writing tasks reflect academic-style English. IELTS General Training is for candidates migrating to English-speaking countries, or applying for secondary education or work experience — its Reading and Writing content reflects everyday, workplace-style English. Listening and Speaking are identical in both versions; only Reading and Writing differ.
The four sections
Every IELTS test has four sections, taken in the same order: Listening (about 30 minutes, 40 questions across 4 recorded sections), Reading (60 minutes, 40 questions across 3 passages), Writing (60 minutes, 2 tasks), and Speaking (11–14 minutes, a face-to-face or video interview in 3 parts). Listening, Reading, and Writing are usually taken back-to-back on the same day; Speaking may be scheduled separately, either the same day or within a few days either side.
How IELTS scoring works
IELTS is scored on a 9-band scale, from Band 1 (non-user) to Band 9 (expert user), in increments of 0.5. You receive a band score for each of the four sections, and an overall band score that averages them (rounded to the nearest 0.5). There is no pass or fail — instead, the institution, employer, or immigration authority you're applying to sets its own minimum required score, which can vary significantly depending on the purpose.
Paper-based vs. computer-delivered
IELTS is now available in both paper-based and computer-delivered formats at many test centres, with identical content and scoring between them — the choice is mostly about personal preference and appointment availability, though computer-delivered tests are usually able to release results faster.
