IELTS Writing Correction
- 1. Use the correct measure Original: percentage of children Suggested revision: average class size Why it matters: The chart reports numbers of pupils per class, not percentages of children.
- 2. Name the school levels Original: at the primary school and lowest secondary schools Suggested revision: in primary and lower secondary schools Why it matters: This wording accurately names the two education levels shown in the chart.
- 3. Lowercase common noun Original: Nations Suggested revision: nations Why it matters: A common plural noun should not be capitalized here.
- 4. Capitalize nationality Original: south Suggested revision: South Why it matters: The proper adjective requires an initial capital letter.
- 5. Correct units and figure Original: 34% and 38% Suggested revision: about 34 and 36 students Why it matters: The chart shows class sizes, and South Korea's lower-secondary figure is about 36 rather than 38.
- 6. Report Japan accurately Original: 26% of the student average Suggested revision: an average class size of about 27 students Why it matters: Japan's primary class contained roughly 27 pupils, not a percentage.
- 7. Correct Japan figure Original: secondary school figure was 32% Suggested revision: the lower secondary figure was about 31 students Why it matters: The visual shows approximately 31 pupils in Japan's lower-secondary classes.
- 8. Use class-size units Original: 15% of primary children Suggested revision: the average primary class size was 15 students Why it matters: The value is an average number of students per class rather than a percentage.
- 9. Report Iceland clearly Original: 17% in the lower secondary institute Suggested revision: 17 students in lower secondary school Why it matters: This revision preserves the correct figure while using the chart's unit and category.
- 10. Describe class sizes Original: have a similar percentage of primary school Suggested revision: had similar primary class sizes Why it matters: The UK and Denmark had similar pupil numbers, not percentages of schools.

Why this response received Band 5.0
The response provides a recognizable overview and some relevant comparisons, especially the highest and lowest countries. Its main weakness is incomplete and unreliable coverage: Mexico is omitted, class sizes are repeatedly presented as percentages, and several figures or comparisons are inaccurate. Prioritize selecting all major features from the chart and checking units and values before writing.
IELTS Writing Criteria Scores
Task Achievement
A clear overview identifies the highest and lowest countries, but Mexico is omitted and several units, values, and comparisons are inaccurate.
Report class sizes as numbers of pupils and cover Mexico and the world averages with carefully checked figures.
Coherence and Cohesion
The response is divided into logical sections, but progression is weakened by unclear comparisons and mechanical linking.
Group countries by similar patterns and make each comparison explicit before moving to the next group.
Lexical Resource
There is enough vocabulary to describe the chart, but frequent inappropriate choices such as academy, institute, and proportion reduce precision.
Use accurate chart language such as average class size, pupils, higher, lower, and compared with.
Grammatical Range and Accuracy
Frequent errors in sentence structure, agreement, articles, and clause formation sometimes make the comparisons difficult to follow.
Build complete comparison sentences with one clear subject and verb, then check agreement and articles.
