International English Language Testing System (IELTS)[6] is an international standardized test of English language proficiency for non-native English language speakers. It is jointly managed by the British Council, IDP and Cambridge English,[6] and was established in 1989. IELTS is one of the major English-language tests in the world. The IELTS test has two modules: Academic and General Training. IELTS One Skill Retake was introduced for computer-delivered tests in 2023, which allows a test taker to retake any one section (Listening, Reading, Writing and Speaking) of the test.[7]

IELTS is accepted by most Australian, British, Canadian, European, Irish and New Zealand academic institutions, by over 3,000 academic institutions in the United States, and by various professional organisations across the world.

IELTS is approved by UK Visas and Immigration (UKVI) as a Secure English Language Test for visa applicants both outside and inside the UK.[8] It also meets requirements for immigration to Australia, where Test of English as a Foreign Language (TOEFL) and Pearson Test of English Academic are also accepted,[9] and New Zealand. In Canada, IELTS, TEF, or CELPIP are accepted by the immigration authority.[10]

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.[11] [12]

In 2017, over 3 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.[3]

In 2019, over 508,000 international students came to study in the UK, making it the world's most popular UK ELT (English Language Test) destination. Over half (54%) of those students were under 18 years old.[13]

History

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 the British 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 English language in the 'real world'.

During the 1980s, test taker numbers were low (4,000 in 1981 rising to 10,000 in 1985) and there were practical difficulties administering the test. As a result, the IELTS Revision Project was set up to oversee the redesign of the test. In order to have international participation in the redesign, the International Development Program of Australian Universities and Colleges (IDP), now known as IDP: IELTS Australia, joined Cambridge English Language Assessment and the British Council to form the international IELTS partnership which delivers the test to this day. This international partnership was reflected in the new name for the test: The International English Language Testing System (IELTS).

IELTS went live in 1989. Test takers took two non-specialised modules, Listening and Speaking, and two specialised modules, Reading and Writing. Test taker numbers rose by approximately 15% per year and by 1995 there were 43,000 test takers in 210 test centres around the world.

IELTS was revised again in 1995, with three main changes:

Further revisions went live in 2001 (revised Speaking Test) and 2005 (new assessment criteria for the Writing test).[14]

IELTS characteristics

IELTS Academic and IELTS General Training are designed to cover the full range of abilities from non-user or middle user to expert user. The Academic version is for test takers who want to study at the 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.[15]

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.[16]

IELTS Academic and General Training both incorporate the following features:

IELTS Test Structure

Modules

There are two modules of the IELTS:

There's also a separate test offered by the IELTS test partners, called IELTS Life Skills:

The four parts of the IELTS test

PartDurationNotes
Listening30 minutesincluding 10 minutes transfer time[18]
Reading60 minutes
Writing60 minutes
Speaking10–15 minutes
Total Test Time2 hours and 45 minutes[19]
Note 1: 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.

Note 2: 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.

Note 3: The 10 minutes transfer time is for the paper-based option of the test. For the computer-delivered option, candidates will be given 2 minutes (at the end of the test) to re-check their answers. [20]

Listening

The module comprises four sections, with ten questions in each section. It takes around 40 (paper-based) or 32 (computer-delivered) minutes: 30 for testing, plus 10 for transferring the answers to an answer sheet (paper-based) or 2 for re-checking the answers (computer-delivered).[21]

Sections 1 and 2 are about everyday, social situations.

Sections 3 and 4 are about educational and training situations

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.[22] 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, candidates are given 10 minutes to transfer their answers to an answer sheet (if they take their test paper-based) or 2 minutes (at the end of the test of course) to re-check the answers (if they do so computer-delivered).[23] Test takers will lose marks for incorrect spelling and grammar.[24]

Reading

The Reading paper has three sections and texts totalling approximately 2,150–3,250 words. There will be a variety of question types, such as multiple-choice, short-answer questions, identifying information, identifying writer's views, labelling 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.

The speaking test is a face-to-face interview between the test taker and an examiner.

The speaking test contains three sections.

Scoring & Band Scale

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.[30]

There is no pass or fail.[31] 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:

BandCompetencyDescription
9 Expert User Has full operational command of the language: appropriate, accurate, and fluent with complete understanding. The individual has a full operational command of the English language. Their use ofEnglish is appropriate, accurate, fluent, and shows complete understanding.[32]
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.

Results

For a computer-delivered test, results are released between 3–5 days.[35] For a paper-based test, a Test Report Form will be sent to test takers 13 days after their test.[36]

It shows:

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.[37]

Locations and test dates

Test takers can take IELTS in more than 140 countries and in over 4,000 locations.[2]

There are up to 48 test dates available per year. Each test centre offers tests up to four times a month depending on local demand. The Academic version is available on all 48 dates per year and the General Training version is available on 24 dates.[38]

There used to be a minimum time limit of 90 days before a person was allowed to retake the test. However this restriction has been withdrawn and currently there is no limit for applicants to retake the test.[39]

Level required by academic institutions for admission

Just over half (51%) of test takers take IELTS to enter higher education in a foreign country.[43] The IELTS minimum scores required by academic institutions and by course vary. As a general rule, the top ranked universities in the United States tend to require a higher IELTS band (typically 7.0). Most universities accept scores between 6–7 as being suitable for undergraduate study in English.[44]

IELTS is used by over 9,000 educational institutions worldwide. This section provides just a few examples of IELTS requirements in different countries. Full details about the organizations which accept IELTS and the scores they require can be found on the IELTS Global Recognition System .

IELTS use for immigration purposes

A number of Commonwealth countries use IELTS scores as a proof of prospective immigrants' competence in English.[97]

Australia

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.[98]

Department of Immigration Level of EnglishMinimum IELTS score (Mar 2019) Visas
Functional English 4.5 every subscore Permanent and provisional skilled visas (to avoid paying the English Language Charge)
Vocational English 5.0 every subscore 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 every subscore 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 every subscore Points Tested Skilled visas (to obtain 10 points)
Superior English 8.0 every subscore 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.[99]

Visa categoryMinimum 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.

Canada

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.[100]

The Canadian Language Benchmarks (CLB) are the national standards used in Canada for describing, measuring and recognizing the English language proficiency of prospective immigrants.[101] The following table shows the IELTS scores needed for each CLB level.[102]

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 categoryMinimum Canadian Language Benchmark (CLB) required (May 2015)
The Federal Skilled Worker Program CLB 7[103]
The Federal Skilled Trades Program CLB 5 for speaking and listening, CLB 4 for reading and writing[104]
The Canadian Experience Class CLB 7 for NOC 0 or A jobs, CLB 5 for NOC B jobs[105]
Business start-up visa CLB 5[106]
Provincial Nominee Programs CLB 4 for NOC C and D jobs[107]

Submitting one's IELTS scores is also one of the several ways to prove one's proficiency in an official language when applying for Canadian citizenship (minimum of CLB level 4 required).[108]

United Kingdom

On 6 April 2015, UK Visas and Immigration (UKVI) changed its English language requirements for UK visa and immigration applications.

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.

VisaMinimum CEFR level required (May 2015) Minimum IELTS score required overall and in each skill (May 2015)[109]
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.[109]
