IELTS Scoring System: How Band Scores Are Calculated

Quick Answer: The IELTS scoring system uses a 9-band scale (1=non-user, 9=expert user). Your overall band score is the average of four section scores (Listening, Reading, Writing, Speaking), rounded to the nearest half band. Each section is scored differently: Listening and Reading are based on correct answers (raw score converted to band), while Writing and Speaking are assessed by trained examiners using detailed criteria (Task Achievement, Coherence & Cohesion, Lexical Resource, Grammatical Range & Accuracy for Writing; Fluency & Coherence, Lexical Resource, Grammatical Range & Accuracy, Pronunciation for Speaking).

How the IELTS 9-Band Scale Works

The IELTS band score ranges from 0 (did not attempt the test) to 9 (expert user). Each band describes a level of English proficiency. For example:

Band 9: Fully operational command of the language – appropriate, accurate, and fluent with complete understanding.

Band 7: Good user – has operational command of the language, though with occasional inaccuracies and misunderstandings in some situations.

Band 5: Modest user – has partial command of the language, coping with overall meaning in most situations, though is likely to make many mistakes.

Your score is reported for each of the four skills (Listening, Reading, Writing, Speaking) and as an overall band score. The overall band score is the average of the four individual scores, rounded to the nearest half band. For example, if you receive 6.5, 7.0, 6.0, 6.5, the average is 6.5, which is your overall band.

Listening and Reading: Raw Score to Band Score Conversion

Both Listening and Reading are scored based on the number of correct answers (raw score). There is no penalty for wrong answers. The raw score is converted to a band score using a conversion table that varies slightly between tests. However, the IELTS provides a general guide:

Raw Score (out of 40)	Approximate Band Score
39-40	9.0
37-38	8.5
35-36	8.0
32-34	7.5
30-31	7.0
26-29	6.5
23-25	6.0
18-22	5.5
16-17	5.0
13-15	4.5
10-12	4.0

Important: The conversion can differ slightly between Academic and General Training Reading modules. General Training Reading is considered slightly easier, so you need more correct answers to achieve the same band score. For example, to get Band 7 in Academic Reading you need 30-31 correct; for General Training you need 34-35.

Writing: Assessment Criteria and Band Descriptors

The Writing section (both Task 1 and Task 2) is assessed by a trained examiner using four criteria, each equally weighted (25% of the task score):

Task Achievement (TA) – How fully you address the task, present key features, and provide a clear overview (Task 1) or develop a position (Task 2).

Coherence and Cohesion (CC) – How logically you organize ideas, use paragraphing, and link sentences/paragraphs.

Lexical Resource (LR) – The range and accuracy of vocabulary you use.

Grammatical Range and Accuracy (GRA) – The variety and correctness of sentence structures.

Each criterion is scored on a 0-9 scale. The average of the four criteria gives the band for that task. Then the overall Writing band is the average of Task 1 and Task 2 (with Task 2 weighted double). However, for simplicity, many test-takers focus on the criteria individually.

Example descriptors for Band 7:

TA: Addresses all parts of the task; presents a clear position with relevant main ideas.

CC: Logically organizes information; uses a range of cohesive devices appropriately.

LR: Uses a sufficient range of vocabulary to allow some flexibility and precision; uses less common vocabulary with some awareness of style and collocation.

GRA: Uses a variety of complex structures; produces frequent error-free sentences; has good control of grammar and punctuation.

Speaking: Assessment Criteria and Band Descriptors

The Speaking test is also assessed by a trained examiner (or via recorded audio for computer-delivered tests) using four criteria, each equally weighted:

Fluency and Coherence (FC) – How smoothly you speak, your rate of speech, and how logically you connect ideas.

Lexical Resource (LR) – Same as Writing – range and accuracy of vocabulary.

Grammatical Range and Accuracy (GRA) – Same as Writing – variety and correctness of grammar.

Pronunciation (P) – How clear and natural your speech sounds, including stress, intonation, and individual sounds.

Each criterion is scored 0-9. The average gives your Speaking band.

Overall Band Score Calculation

Your overall band score is the mean of the four individual section scores, rounded to the nearest half band. Rounding rules:

If the average ends in .25, round up to the next half band (e.g., 6.25 → 6.5).

If the average ends in .75, round up to the next whole band (e.g., 6.75 → 7.0).

If the average ends in .1, .2, .3, .4, round down to the nearest half band (e.g., 6.1 → 6.0; 6.4 → 6.0? Actually .4 rounds down to .0? Let's clarify: IELTS rounds to the nearest half band. 6.125 → 6.0; 6.25 → 6.5; 6.375 → 6.5; 6.5 → 6.5; 6.625 → 6.5; 6.75 → 7.0; 6.875 → 7.0. So 6.4 is closer to 6.5? Actually 6.4 is 0.1 away from 6.5 and 0.4 away from 6.0, so it rounds to 6.5? No, standard rounding to nearest half: 6.4 is between 6.0 and 6.5. The midpoint between 6.0 and 6.5 is 6.25. 6.4 > 6.25, so it rounds up to 6.5. But IELTS official rounding: they take the average and round to the nearest .5. If the average is exactly halfway (e.g., 6.25), it rounds up. So 6.4 rounds to 6.5. Let's be precise: use the rule that .25 rounds up, .75 rounds up. So 6.1, 6.2, 6.3, 6.4 all round to 6.5? No, 6.1 is below 6.25 so it rounds to 6.0? Actually 6.1 is closer to 6.0 than 6.5? Distance to 6.0 = 0.1, to 6.5 = 0.4, so rounds to 6.0. So only .25 and above round up to the next half. So 6.0-6.24 → 6.0; 6.25-6.74 → 6.5; 6.75-7.24 → 7.0, etc. So 6.4 is 6.4, which is >6.25, so rounds to 6.5. Good.

Band Score Comparison Table

Band	What Examiner Wants (General Description)
6	Competent user: has effective command despite some inaccuracies and misunderstandings. Can use fairly complex language, especially in familiar situations.
7	Good user: has operational command, with occasional inaccuracies and misunderstandings. Handles complex language well and understands detailed reasoning.
8	Very good user: has fully operational command with only occasional unsystematic inaccuracies. Handles detailed argumentation well.
9	Expert user: fully operational command – appropriate, accurate, fluent, with complete understanding.

Sample Answers: Writing Task 2

Prompt: Some people think that governments should spend more money on public services rather than on the arts. To what extent do you agree or disagree? Band 7: I partly agree that public services deserve more funding, but I believe the arts also play a vital role. Public services like healthcare and education are essential for a society’s basic functioning. However, arts contribute to cultural identity and creativity, which can boost tourism and well-being. Therefore, a balanced approach is necessary. (This answer addresses the task, uses some cohesive devices, but lacks depth in vocabulary and grammar.) Band 8: While I concur that public services should be a funding priority, I strongly contend that the arts should not be neglected. Firstly, sectors such as healthcare and infrastructure directly impact citizens' quality of life. For instance, underfunded hospitals lead to longer waiting times. Nevertheless, the arts foster innovation and social cohesion. A society without cultural expression risks becoming sterile. Thus, a prudent government would allocate resources proportionally, perhaps using arts funding to also promote public spaces. (Clear position, good range of vocabulary, complex sentences, logical flow.) Band 9: I wholeheartedly agree that public services warrant greater fiscal attention, but I would argue that the arts are not a luxury but a necessity. To elaborate, basic services – healthcare, education, transport – form the bedrock of societal well-being. For example, a nation with inadequate healthcare infrastructure cannot achieve sustainable development. Conversely, the arts are not merely ornamental; they cultivate critical thinking, preserve heritage, and drive economic growth through creative industries. A sophisticated government recognizes that investing in the arts yields long-term dividends in social capital. Therefore, rather than an either-or dichotomy, a synergistic funding model – where arts programs are integrated into public service initiatives – would be most efficacious. (Sophisticated vocabulary, complex structures, nuanced argument, perfect coherence.)

Common Mistakes

❌Assuming Listening/Reading scores are the same for both Academic and General Training. The raw score conversion differs, especially for Reading. Always check the specific conversion table for your test type.

❌Neglecting the rounding rule for overall band. Many students think 6.25 becomes 6.0, but it actually becomes 6.5. Know the .25 and .75 rules.

❌Focusing only on one criterion in Writing/Speaking. All four criteria are equally important. A high Lexical Resource score cannot compensate for low Task Achievement.

Top Tips

For Listening/Reading: Practice with official IELTS practice tests to understand the typical raw-score-to-band conversion. Aim for at least 30 correct for Band 7.

For Writing: Always plan your essay. Use a clear structure (introduction, body paragraphs, conclusion). Use a range of linking words but don't overdo it.

For Speaking: Record yourself and listen for fluency and pronunciation. Practice speaking for 2 minutes without stopping on a random topic.

FAQ

Q: How is the overall band score calculated if my scores are 6.5, 7.0, 6.0, 6.5? A: Average = (6.5+7.0+6.0+6.5)/4 = 26/4 = 6.5. No rounding needed. Q: Can I get a band score of 6.75? A: No, band scores are reported in whole or half bands only (e.g., 6.0, 6.5, 7.0). 6.75 would be rounded up to 7.0. Q: Do I lose marks for wrong answers in Listening/Reading? A: No. Only correct answers count. There is no negative marking. Q: How long does it take to get my IELTS results? A: For paper-based, 13 days. For computer-delivered, 3-5 days.
