IELTS Writing Task 1 question

Summarise the infonnation by selecting and reporting the main features, and make comparisons where relevant.
Past and projected future overweight rates in selected OECD countries
Student answer (Band 7.5)
The line graph illustrates historical data and future predictions regarding the proportion of overweight people in nine OECD nations between 1970 and 2020.
Overall, it is clear that the percentage of overweight individuals showed an upward trend across all countries over the 50-year period. The USA consistently recorded the highest figures throughout the timeframe, whereas Korea had by far the lowest proportion.
In terms of the nations with the highest rates, the USA began at around 46% in 1970 and saw a continuous rise, with projections indicating it will exceed 70% by 2020. Similarly, England experienced significant growth from approximately 43% in the late 1980s to an estimated 69% in 2020. Canada and Spain also followed an upward trend; Canada is expected to approach 60%, while Spain's rate is set to reach roughly 50% by the end of the period.
Looking at the remaining countries, Austria, Italy, Australia and France fluctuated within a moderate range between roughly 30% and 40%. While Australia and France saw slight overall increase, Austria and Italy plateaued and showed minor drops after 2000. Finally, Korea started below 30% in the late 1990s and despite a gradual climb to just under 40% by 2020, remained the lowest among all nine nations.

Task Achievement / Task Response: Band 7.5
The student successfully addresses all parts of the task by providing a clear and comprehensive overview of the line graph. The main features and trends are accurately reported, such as the overall upward trajectory across all countries and the distinct positions of the USA and Korea as the highest and lowest, respectively. Key data points are selected effectively to support the description, such as the USA starting around 46% in 1970 and projections reaching over 70%. Although there are minor approximations in the cited figures, they align well with the visual data provided. The response demonstrates a well-developed overview and satisfies all requirements for this criterion at a high level.
Coherence and Cohesion: Band 8.0
The response is logically organized with a clear overall progression. It begins with a concise introduction, followed by a strong overall trend paragraph, and then splits the detailed body paragraphs effectively between the nations with the highest rates and those with moderate or lower rates. Cohesive devices such as 'Overall', 'In terms of', and 'Looking at the remaining countries' are used naturally and appropriately to guide the reader through the data. Paragraphing is used skillfully, ensuring each section has a distinct and manageable focus.
Lexical Resource: Band 7.5
The student demonstrates a wide and flexible range of vocabulary suited to academic report writing. Phrases like 'proportion of overweight people', 'upward trend', 'continuously rise', and 'plateaued' show an ability to use less common lexical items with good control of style and collocation. Word choices are precise, and there are virtually no lexical errors throughout the text. The student avoids repetitive language by skillfully varying synonyms to describe increases and decreases in the data.
Grammatical Range and Accuracy: Band 7.5
The writing exhibits a wide range of complex sentence structures used accurately and flexibly. The majority of sentences are error-free, featuring well-controlled dependent clauses and comparative structures, such as 'while Australia and France saw slight overall increase, Austria and Italy plateaued'. Grammar and punctuation are handled with a high degree of precision, with only occasional minor slips that never impede understanding. The control over tense usage—shifting between past data and future projections—is particularly impressive.
