IELTS

The International English Language Testing System (IELTS) is the world’s most widely-used English language proficiency assessment, administered jointly by the British Council, IDP: IELTS Australia, and Cambridge English Assessment. IELTS measures listening, reading, writing, and speaking across a 0–9 band scale. It is accepted by universities in the UK, Australia, Canada, New Zealand, the US, and dozens of other countries for student visa applications and higher education admissions. The test is offered in two modules—Academic (for university study) and General (for immigration and vocational purposes)—and results remain valid for two years.

Score structure

IELTS is divided into four skills, each scored 0–9:

• Listening (40 minutes, 40 items). Candidates hear four recordings (native speakers in various accents) and answer multiple-choice, short-answer, form-completion, and matching questions. Tests comprehension of main ideas, details, opinions, and inferences. Score reflects overall listening accuracy.

• Reading (60 minutes, 40 items). Academic module uses three passages of 650–900 words from books, journals, and periodicals; General module uses everyday texts (advertisements, manuals). Task types include multiple choice, True/False/Not Given, heading matching, and summary completion. Score reflects reading speed and comprehension accuracy.

• Writing (60 minutes, two tasks).

  • Task 1: Academic candidates describe data (chart/table/diagram) in 150+ words; General candidates write a letter in 150+ words.
  • Task 2: Both write a persuasive/discursive essay in 250+ words.
  • Scored on Task Achievement/Response, Coherence & Cohesion, Lexical Range, and Grammatical Accuracy.

• Speaking (11–14 minutes). One-to-one conversation with an examiner across three parts: introduction (4–5 min), topic card (3–4 min), abstract discussion (4–5 min). Scored on Fluency & Coherence, Lexical Range, Grammatical Accuracy, and Pronunciation.

Overall band score is the average of the four skills rounded to the nearest 0.5.
