How is IELTS scored?


Okay, so I’m prepping for the IELTS exam and I’m finding the scoring system a little confusing. I get that it’s a band score from 0-9, but how do they arrive at that number? What are the specific criteria they’re looking at in each section – Listening, Reading, Writing, and Speaking?

For example, in the Writing section, are they mainly focused on grammar and vocabulary, or is organization and task response more important? Does everyone get the same writing tasks?

And in Speaking, how much does my accent matter? I’m not a native English speaker, so I definitely have an accent. Will that negatively impact my score, even if my grammar is good?

I’m also wondering about the Listening and Reading sections. Is it just a matter of getting the answers right, or are there penalties for spelling mistakes (even minor ones)?

Basically, I’m looking for a breakdown of how each section is assessed and weighed to determine the overall band score. The official IELTS website is helpful, but I’m hoping to get a more detailed explanation or insights from people who’ve taken the test before. Thanks!

Answer

The International English Language Testing System (IELTS) is scored on a 9-band scale, where each band corresponds to a specific level of English proficiency. The scale ranges from Band 1 ("Non-User") to Band 9 ("Expert User"). Both the Academic and General Training versions of the test use the same scoring system.

Overall Band Score:

The Overall Band Score is the average of the scores achieved in the four modules: Listening, Reading, Writing, and Speaking. The individual band scores for each module are added together, and then the sum is divided by four. The resulting average is rounded to the nearest whole or half band.

  • If the average ends in .25, it is rounded up to the next half band. For example, 6.25 becomes 6.5.
  • If the average ends in .75, it is rounded up to the next whole band. For example, 6.75 becomes 7.0.

Individual Module Scores:

Each of the four modules is scored independently:

1. Listening and Reading:

  • Both the Listening and Reading modules consist of 40 questions.
  • Each correct answer is awarded one mark.
  • The total number of correct answers is converted into a band score using a standardized conversion table. This conversion table may vary slightly from test to test to account for differences in difficulty.
  • There is no penalty for incorrect answers; therefore, candidates should attempt all questions.

2. Writing:

  • The Writing module is assessed by trained IELTS examiners according to specific criteria outlined in the IELTS Writing band descriptors. There are separate band descriptors for Task 1 and Task 2.
  • The criteria are:

    • Task Achievement (for Task 1) / Task Response (for Task 2): This assesses how well the candidate addresses the task, presents a clear purpose, and fulfills the requirements of the question. Task 1 assesses the ability to accurately describe and present information, while Task 2 evaluates the ability to develop a relevant and well-supported argument or opinion.
    • Coherence and Cohesion: This assesses the organization and structure of the response, the logical flow of ideas, and the effective use of cohesive devices (e.g., linking words, pronouns).
    • Lexical Resource: This assesses the range of vocabulary used, the accuracy of word choice, and the ability to use less common vocabulary appropriately.
    • Grammatical Range and Accuracy: This assesses the range of grammatical structures used, the accuracy of grammar and punctuation, and the ability to use complex sentences effectively.
  • Examiners assign a band score for each of these four criteria. The overall Writing band score is the average of these four scores. Task 2 is weighted more heavily than Task 1 in the overall score.
  • Examiners are trained to apply the band descriptors consistently and fairly.

3. Speaking:

  • The Speaking module is also assessed by trained IELTS examiners using specific criteria outlined in the IELTS Speaking band descriptors.
  • The criteria are:

    • Fluency and Coherence: This assesses the ability to speak at length without noticeable effort or loss of coherence. It also evaluates the logical flow of ideas and the effective use of discourse markers.
    • Lexical Resource: This assesses the range of vocabulary used, the accuracy of word choice, and the ability to use less common vocabulary appropriately.
    • Grammatical Range and Accuracy: This assesses the range of grammatical structures used, the accuracy of grammar and pronunciation, and the ability to use complex sentences effectively.
    • Pronunciation: This assesses the clarity of speech, the ability to be understood easily, and the effective use of intonation and stress. Accent is only considered if it affects clarity.
  • Examiners assign a band score for each of these four criteria. The overall Speaking band score is the average of these four scores.
  • Examiners are trained to apply the band descriptors consistently and fairly. The Speaking test is recorded for monitoring purposes and to ensure consistent scoring standards.

Band Descriptors:

The IELTS band descriptors provide a detailed description of the abilities of candidates at each band level. These descriptors are used by examiners to assess performance in the Writing and Speaking modules and can also be used by candidates to understand what is expected at each band level. They can be found on the official IELTS website.

Reporting and Validity:

  • Test Report Forms (TRFs) are issued to candidates, showing their Overall Band Score and their individual band scores for each module.
  • IELTS scores are generally valid for two years. Organizations may have their own policies regarding the acceptance of scores older than two years.

The scoring process is designed to be fair, reliable, and consistent, providing an accurate reflection of a candidate’s English language proficiency.
