IELTS Band Score Chart: How Marks Are Calculated Across All Four Sections

Demystify how raw marks out of 40 convert into IELTS Bands 4.0 to 9.0. Explore verified conversion tables for Listening, Academic Reading, and General Reading, plus the official arithmetic rounding rules.

Every candidate preparing for the IELTS exam in Malaysia asks the same fundamental question: "Exactly how many questions do I need to get right to achieve my target band score?"

Unlike percentage-based school examinations, IELTS converts raw marks (0 to 40) in Listening and Reading into standardized band scores from Band 1.0 to 9.0 using empirical psychometric scaling. In Writing and Speaking, certified examiners assess your performance against four qualitative criteria before computing sub-band scores. Finally, the four sub-scores are mathematically aggregated and rounded to yield your Overall Band Score.

This guide provides the authoritative conversion charts, explores the subtle differences between Academic and General Training Reading, and details the exact arithmetic rounding rules governing your official Test Report Form (TRF).

1. Raw Score Conversion: IELTS Listening (Out of 40)

The Listening test is identical for both Academic and General Training candidates. All questions carry equal value (1 mark per correct answer).

| Raw Score (Out of 40) | IELTS Band Score | Indicative CEFR Level | | :--- | :--- | :--- | | 39 – 40 | Band 9.0 | C2 (Mastery) | | 37 – 38 | Band 8.5 | C2 | | 35 – 36 | Band 8.0 | C1 (Effective Operational Proficiency) | | 32 – 34 | Band 7.5 | C1 | | 30 – 31 | Band 7.0 | C1 | | 26 – 29 | Band 6.5 | B2 (Vantage) | | 23 – 25 | Band 6.0 | B2 | | 18 – 22 | Band 5.5 | B2 | | 16 – 17 | Band 5.0 | B1 (Threshold) | | 13 – 15 | Band 4.5 | B1 |

Takeaway: To secure a solid Band 7.0 in Listening, your target is 30 correct answers out of 40. This allows you a margin of 10 errors.

2. Raw Score Conversion: Academic Reading vs. General Training Reading

Because the textual complexity of Academic Reading passages is substantially higher than General Training passages, the raw mark thresholds differ significantly:

| Target Band Score | Academic Reading (Raw /40) | General Training Reading (Raw /40) | | :--- | :--- | :--- | | Band 9.0 | 39 – 40 | 40 | | Band 8.5 | 37 – 38 | 39 | | Band 8.0 | 35 – 36 | 37 – 38 | | Band 7.5 | 33 – 34 | 36 | | Band 7.0 | 30 – 32 | 34 – 35 | | Band 6.5 | 27 – 29 | 32 – 33 | | Band 6.0 | 23 – 26 | 30 – 31 | | Band 5.5 | 19 – 22 | 27 – 29 | | Band 5.0 | 15 – 18 | 23 – 26 |

Critical Insight: A score of 30 out of 40 yields Band 7.0 in Academic Reading, but only Band 6.0 in General Training Reading. General Training candidates have virtually zero room for careless errors.

3. Writing and Speaking: The Four Rubric Criteria

Writing and Speaking do not use raw marks out of 40. Instead, certified examiners award marks from 0 to 9 across four equally-weighted assessment criteria:

Writing Assessment Criteria (Task 1 & Task 2) 1. Task Achievement (Task 1) / Task Response (Task 2) (25%) 2. Coherence and Cohesion (25%) 3. Lexical Resource (25%) 4. Grammatical Range and Accuracy (25%)

Calculation: (Criteria 1 + Criteria 2 + Criteria 3 + Criteria 4) / 4 = Task Band. Because Task 2 carries twice the weight of Task 1, your overall Writing band is calculated as: $ ext{Writing Band} = rac{ ext{Task 1 Score} + (2 imes ext{Task 2 Score})}{3}$

Speaking Assessment Criteria 1. Fluency and Coherence (25%) 2. Lexical Resource (25%) 3. Grammatical Range and Accuracy (25%) 4. Pronunciation (25%)

4. Overall Band Calculation and Rounding Rules

Your overall band score is calculated by taking the mathematical mean of all four individual sub-scores. The result is rounded to the nearest whole or half-band according to the official Cambridge rounding protocol:

OFFICIAL ARITHMETIC ROUNDING EXAMPLES

Listening: 6.5 | Reading: 6.5 | Writing: 6.0 | Speaking: 6.0
Mean: (6.5 + 6.5 + 6.0 + 6.0) / 4 = 25.0 / 4 = 6.25
Final Result: 6.5 (Rounds UP to next half-band)

Listening: 7.0 | Reading: 7.5 | Writing: 6.5 | Speaking: 6.0
Mean: (7.0 + 7.5 + 6.5 + 6.0) / 4 = 27.0 / 4 = 6.75
Final Result: 7.0 (Rounds UP to next whole band)

Listening: 6.5 | Reading: 6.0 | Writing: 6.0 | Speaking: 6.0
Mean: (6.5 + 6.0 + 6.0 + 6.0) / 4 = 24.5 / 4 = 6.125
Final Result: 6.0 (Rounds DOWN to nearest whole band)

Understanding this mathematical threshold allows you to craft strategic target combinations. For example, if you are strong in Listening and Reading (scoring 7.5 and 7.5), you only need a 6.0 in Writing and a 6.0 in Speaking to achieve an Overall Band 7.0 $(7.5 + 7.5 + 6.0 + 6.0 = 27.0 / 4 = 6.75 ightarrow 7.0)$.
