The English Language Testing Service (ELTS), as IELTS was then known, was launched in 1980 by Cambridge English Language Assessment (then known as UCLES) and theBritish Council. It had an innovative format, which reflected changes in language learning and teaching, including the growth in ‘communicative’ language learning and ‘English for specific purposes’. Test tasks were intended to reflect the use of language in the ‘real world’.
The International English Language Testing System or IELTS / is an international standardised test of English language proficiency for non-native English language speakers. It is jointly managed by the British CouncilIDP: IELTS Australia and Cambridge English Language Assessment, and was established in 1989. IELTS is one of the major English-language tests in the world, others being the TOEFLTOEIC and OPI/OPIc.
IELTS is accepted by most AustralianBritishCanadian and New Zealand academic institutions, by over 3,000 academic institutions in the United States, and by various professional organizations across the  Europe andworld.
IELTS is the only Secure English Language Test approved by UK Visas and Immigration (UKVI) for visa customers applying both outside and inside the UK. It is also a requirement for immigration to Australia and New Zealand. In Canada, IELTS, TEF, or CELPIP are accepted by the immigration authority.
No minimum score is required to pass the test. An IELTS result or Test Report Form is issued to all test takers with a score from "band 1" ("non-user") to "band 9" ("expert user") and each institution sets a different threshold. There is also a "band 0" score for those who did not attempt the test. Institutions are advised not to consider a report older than two years to be valid, unless the user proves that they have worked to maintain their level.
In 2014, 2.5 million tests were taken in more than 140 countries, up from 2 million tests in 2012, 1.7 million tests in 2011 and 1.4 million tests in 2009. In 2007, IELTS administered more than one million tests in a single 12-month period for the first time ever, making it the world's most popular English language test for higher education and immigration.
There are two modules of the IELTS:
·         Academic Module and
·         General Training Module
  • IELTS Academic is intended for those who want to enroll in universities and other institutions of higher education and for professionals such as medical doctors and nurses who want to study or practice in an English-speaking country.
  • IELTS General Training is intended for those planning to undertake non-academic training or to gain work experience, or for immigration purposes.
IELTS Academic and IELTS General Training are designed to cover the full range of ability from non-user to expert user. The Academic version is for test takers who want to study at tertiary level in an English-speaking country or seek professional registration. The General Training version is for test takers who want to work, train, study at a secondary school or migrate to an English-speaking country.
The difference between the Academic and General Training versions is the content, context and purpose of the tasks. All other features, such as timing allocation, length of written responses and reporting of scores, are the same.
There is also a separate test offered by the IELTS test partners, called IELTS Life Skills:
·         IELTS Life Skills is intended for those who need to prove their English speaking and listening skills at Common European Framework of Reference for Languages (CEFR) levels A1 or B1 and can be used to apply for a ‘family of a settled person’ visa, indefinite leave to remain or citizenship in the UK
The IELTS test has four parts[
·         Listening: 30 minutes (plus 10 minutes' transfer to transfer in the answer sheet)
·         Reading: 60 minutes
·         Writing: 60 minutes
·         Speaking: 11–14 minutes
The test total time is: 2 hours and 45 minutes
Listening, Reading and Writing are completed in one sitting. The Speaking test may be taken on the same day or up to seven days before or after the other tests.
All test takers take the same Listening and Speaking tests, while the Reading and Writing tests differ depending on whether the test taker is taking the Academic or General Training versions of the test.
The module comprises four sections, with ten questions in each section. It takes 40 minutes: 30 - for testing, plus 10 for transferring the answers to an answer sheet.
Sections 1 and 2 are about every day, social situation.
·         Section 1 has a conversation between two speakers (for example, a conversation about travel arrangements)
·         Section 2 has one person speaking (for example, a speech about local facilities).
Sections 3 and 4 are about educational and training situations
·         Section 3 is a conversation between two main speakers (for example, a discussion between two university students, perhaps guided by a tutor)
·         Section 4 has one person speaking about an academic subject.
Each section begins with a short introduction telling the test taker about the situation and the speakers. Then they have some time to look through the questions. The questions are in the same order as the information in the recording, so the answer to the first question will be before the answer to the second question, and so on.[13] The first three sections have a break in the middle allowing test takers to look at the remaining questions. Each section is heard only once.
At the end of the test students are given 10 minutes to transfer their answers to an answer sheet.[15] Test takers will lose marks for incorrect spelling and grammar
The Reading paper has three sections and texts totaling 2,150-2,750 words. There will be a variety of question types, such as multiple choice, short-answer questions, identifying information, identifying writer’s views, labeling diagrams, completing a summary using words taken from the text and matching information/headings/features in the text/sentence endings. Test takers should be careful when writing down their answers as they will lose marks for incorrect spelling and grammar.
Texts in IELTS Academic
·         Three reading texts, which come from books, journals, magazines, newspapers and online resources written for non-specialist audiences. All the topics are of general interest to students at undergraduate or postgraduate level.
Texts in IELTS General Training
·         Section 1 contains two or three short texts or several shorter texts, which deal with everyday topics. For example, timetables or notices – things a person would need to understand when living in an English-speaking country.
·         Section 2 contains two texts, which deal with work. For example, job descriptions, contracts, training materials.
·         Section 3 contains one long text about a topic of general interest. The text is generally descriptive, longer and more complex than the texts in Sections 1 and 2. The text will be taken from a newspaper, magazine, book or online resource.
The Writing paper has two tasks which must both be completed. In task 1 test takers write at least 150 words in about 20 minutes. In task 2 test takers write at least 250 words in about 40 minutes. Test takers will be penalized if their answer is too short or does not relate to the topic. Answers should be written in full sentences (test takers must not use notes or bullet points).
IELTS Academic
·         Task 1: test takers describe a graph, table, chart or diagram in their own words.
·         Task 2: test takers discuss a point of view, argument or problem. Depending on the task, test takers may be required to present a solution to a problem, present and justify an opinion, compare and contrast evidence, opinions and implications, and evaluate and challenge ideas, evidence or an argument.[19]
IELTS General Training
·         Task 1: test takers write a letter in response to a given everyday situation. For example, writing to an accommodation officer about problems with your accommodation, writing to a new employer about problems managing your time, writing to a local newspaper about a plan to develop a local airport.
·         Task 2: test takers write an essay about a topic of general interests. For example, whether smoking should be banned in public places, whether children’s leisure activities should be educational, how environmental problems can be solved.
The speaking test is a face-to-face interview between the test taker and an examiner.
The speaking test contains three sections.
·         Section 1: introduction and interview (4–5 minutes). Test takers may be asked about their home, family, work, studies, hobbies, interests, reasons for taking IELTS exam as well as other general topics such as clothing, free time, computers and the internet.
·         Section 2: long turn (3–4 minutes). Test takers are given a task card about a particular topic. Test takers have one minute to prepare to talk about this topic. The task card states the points that should be included in the talk and one aspect of the topic which must be explained during the talk. Test takers are then expected to talk about the topic for 2 minutes, after which the examiner may ask one or two questions.
·         Section 3: discussions (4–5 minutes). The third section involves a discussion between the examiner and the test taker, generally on questions relating to the theme which they have already spoken about in Section 2.
  • Test takers receive a score for each test component – Listening, Reading, Writing and Speaking. The individual scores are then averaged and rounded to produce an Overall Band Score.[22]
  • Band scale
  • There is no pass or fail IELTS is scored on a nine-band scale, with each band corresponding to a specified competence in English. Overall Band Scores are reported to the nearest half band.
  • The following rounding convention applies: if the average across the four skills ends in .25, it is rounded up to the next half band, and if it ends in .75, it is rounded up to the next whole band.
  • The nine bands are described as follows:
9 Expert User Has full operational command of the language: appropriate, accurate and fluent with complete understanding.
8 Very Good User Has fully operational command of the language with only occasional unsystematic inaccuracies and inappropriacies. Misunderstandings may occur in unfamiliar situations. Handles complex detailed argumentation well.
7 Good User Has operational command of the language, though with occasional inaccuracies, inappropriateness and misunderstandings in some situations. Generally handles complex language well and understands detailed reasoning.
6 Competent User Has generally effective command of the language despite some inaccuracies, inappropriacies and misunderstandings. Can use and understand fairly complex language, particularly in familiar situations.
5 Modest user Has partial command of the language, coping with overall meaning in most situations, though is likely to make many mistakes. Should be able to handle basic communication in own field.
4 Limited User Basic competence is limited to familiar situations. Has frequent problems in understanding and expression. Is not able to use complex language.
3 Extremely Limited User Conveys and understands only general meaning in very familiar situations. Frequent breakdowns in communication occur.
2 Intermittent User No real communication is possible except for the most basic information using isolated words or short formulae in familiar situations and to meet immediate needs. Has great difficulty understanding spoken and written English.
1 Non User Essentially has no ability to use the language beyond possibly a few isolated words.
0 Did not attempt the test No assessable information provided at all.

Conversion table

This table can be used to convert raw scores (out of 40) to band scores (out of 9). This helps test takers understand how many correct answers they need to achieve a particular band score. This chart is a guide only because sometimes the scores adjust slightly depending on how difficult the test is.
Band Score 9.0 8.5 8.0 7.5 7.0 6.5 6.0 5.5 5.0 4.5 4.0 3.5 3.0 2.5

A Test Report Form is posted to test takers 13 days after their test. It shows:
·         An Overall Band Score (from 1-9)
·         A band score (from 1-9) for each section of the test (Listening, Reading, Writing and Speaking)
·         Whether IELTS Academic or General Training was completed
·         The test taker’s photo, nationality, first language and date of birth.
Test takers receive one copy of their Test Report Form, apart from test takers who are applying to the Department of Citizenship and Immigration Canada (CIC) or UK Visas and Immigration (UKVI) who receive two copies.
Test Report Forms are valid for two years

IELTS use for immigration purposes

A number of Commonwealth countries use IELTS scores as a proof of prospective immigrants' competence in English.


Australia's immigration authorities have used IELTS to assess English proficiency of prospective migrants since May 1998, when this test replaced the access: test that had been previously used.
There are different IELTS score requirements for different types of visa.
Department of Immigration Level of English Minimum IELTS score (May 2015) Visas
Functional English 4.5 Permanent and provisional skilled visas (to avoid paying the English Language Charge)
Vocational English 5.0 457 visa, ENS and RSMS visas through the Temporary Residence Transitional stream for people who have held a 457 visa for 2 years with the employer
Competent English 6.0 ENS and RSMS visas through the Direct Entry Stream, Skilled migration (6.0 is the minimum threshold, but receives 0 points)
Proficient English 7.0 Points Tested Skilled visas (to obtain 10 points)
Superior English 8.0 Points Tested Skilled visas (to obtain 20 points)

New Zealand

New Zealand has used the IELTS test since 1995. There are different IELTS score requirements for different types of visa and type of applicant.
Visa category Minimum IELTS score required if the applicant is not demonstrating the minimum standard in another way (May 2015)
Skilled Migrant Principal applicant: 6.5. Partners and children aged 16 and over: 5.0
Business categories (Investor, Entrepreneur, Long Term Business Visa, Employees of Relocating Business) Principal applicants: 5.0. Partners and children aged 16 and over: In some cases partners and children are not required to meet the minimum level of English at the time the application is lodged, but can provide evidence at a later stage.
Originally, applicants who could not achieve the required score could pay a NZ$20,000 fee instead, which would be fully or partially refunded later if the migrant were able to successfully take the test within a certain period (3 to 12 months) after his or her arrival to the country. A few years later, the policy was changed: the fee was reduced, and, instead of being potentially refundable, it became treated as a "pre-purchase" of post-arrival ESL tuition.


Citizenship and Immigration Canada (CIC) uses IELTS and/or TEF as evidence of one's ability to communicate in English and/or French. The CELPIP (Canadian English Language Proficiency Index Program) test scores are an alternative to IELTS.
The Canadian Language Benchmarks (CLB) are the national standards used in Canada for describing, measuring and recognizing the English language proficiency of prospective immigrants. The following table shows the IELTS scores needed for each CLB level.
Canadian Language Benchmark (CLB) Reading Writing Listening Speaking
10 8.0 7.5 8.5 7.5
9 7.0 7.0 8.0 7.0
8 6.5 6.5 7.5 6.5
7 6.0 6.0 6.0 6.0
6 5.0 5.5 5.5 5.5
5 4.0 5.0 5.0 5.0
4 3.5 4.0 4.5 4.0
There are different language requirements for different types of immigration program as shown below:
Visa category Minimum Canadian Language Benchmark (CLB) required (May 2015)
The Federal Skilled Worker Program CLB 7
The Federal Skilled Trades Program CLB 5 for speaking and listening, CLB 4 for reading and writing
The Canadian Experience Class CLB 7 for NOC 0 or A jobs, CLB 5 for NOC B jobs
Business start-up visa CLB 5
Provincial Nominee Programs CLB 4 for NOC C and D jobs
Submitting one's IELTS scores is also one of the several ways to evidence one's proficiency in an official language when applying for Canadian citizenship (minimum of CLB level 4 required).

United Kingdom

On 6 April 2015, UK Visas and Immigration (UKVI) changed its English language requirements for UK visa and immigration applications. IELTS tests are now one of only two exams included on the UK government list of Secure English Language Tests (SELTs).
IELTS assesses all four language skills and is accepted by UK Visas and Immigration (UKVI) at levels B1 to C2 of the Common European Framework of Reference for Languages(CEFR).
A new test, IELTS Life Skills, assesses Speaking and Listening at CEFR level A1 and at CEFR Level B1. IELTS Life Skills can be used to meet the English language requirements for some classes of visa application, including 'family of a settled person' visas and indefinite leave and citizenship.
To be used for visa and immigration purposes, IELTS and IELTS Life Skills must be taken in test centres approved by the UKVI.
Visa Minimum CEFR level required (May 2015) Minimum IELTS score required overall and in each skill (May 2015)
Tier 1 (General) visa C1 7.0 overall, and in each of the four skills
Tier 1 (Exceptional Talent) visa B1 4.0 overall, and in each of the four skills
Tier 1 (Entrepreneur) visa B1 4.0 overall, and in each of the four skills
Tier 1 (Graduate Entrepreneur) visa B1 4.0 overall, and in each of the four skills
Tier 2 (General) visa B1 4.0 overall, and in each of the four skills
Tier 2 (Sportsperson) visa A1 4.0 overall, and in each of the four skills
Tier 2 (Minister of Religion) visa B2 5.5 overall, and in each of the four skills
Tier 4 (General) student visa - below degree level B1 4.0 overall, and in each of the four skills
Tier 4 (General) student visa - degree level and above and including some pre-sessional courses B2 5.5 overall, and in each of the four skills
‘Family of a settled person’ visa A1 IELTS Life Skills at A1 – Pass, IELTS – 4.0 in Speaking and Listening
Indefinite leave to remain (to settle) or citizenship B1 IELTS Life Skills at B1 – Pass, IELTS – 4.0 in Speaking and Listening
For UK visa purposes the test is designed to meet certain administrative requirements specified by UKVI. These Test Report Forms are slightly different, to show that the test taker has taken the test at an IELTS UKVI session. The actual test taken is the same – same content, examiners, format, level of difficulty, scoring and so on.
