IELTS Writing Task 1 question

The diagram below shows how fabric is manufactured from bamboo.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

Student answer (Band 5.0)

"The diagram illustrate the process of making fabric from bamboo."

Overall, there are several stages in this process, beginning with the growth of bamboo and ending with the production of fabric.

First, bamboo plants are grown and harvested. The bamboo is then cut into small pieces. After that, the pieces are crushed and processed to produce bamboo fibres.

Next the bamboo fibres are treated and made into a soft material. Finally, the material is spun into yarn, which is then woven to produce fabric.

AI examiner evaluation

Task Achievement / Task Response: Band 4.0

The response clearly fails to meet the minimum length requirement of 150 words, containing only 84 words. Because of this severe under-length, it is impossible for the writer to fully develop the response or provide a comprehensive overview with detailed comparisons of all stages in the diagram. Although the student correctly identifies the general nature of the process from bamboo to fabric, key chemical and mechanical steps such as crushing into liquid pulp, filtering, softening with amine oxide, and spinning are either omitted entirely or overly generalized. Consequently, the task is only partially addressed, which caps the score for this criterion.

Coherence and Cohesion: Band 5.5

Despite the very short text, the response demonstrates a logical flow and basic organizational structure. The essay begins with an introductory statement, provides a sequential overview, and uses simple time linkers such as "First", "After that", "Next", and "Finally" to guide the reader through the stages. Paragraphing is adequate for a short response. However, cohesion is somewhat mechanical due to the repetitive use of basic chronological markers, and referencing lacks the sophistication expected at higher bands. Overall, the arrangement is coherent enough to merit a band 6.0 for structural clarity within its limited scope.

Lexical Resource: Band 5.0

The vocabulary used is largely basic and repetitive, such as "process", "fabric", "bamboo", "pieces", and "material". There are minor lexical inaccuracies, notably the subject-verb agreement error in the opening sentence ("The diagram illustrate"). While the writer attempts some appropriate task-specific terminology like "harvested", "fibres", "spun", and "woven", the range of vocabulary is strictly limited and lacks the flexibility and precision required for higher band levels. Word choices are adequate to convey the basic meaning, but they do not demonstrate resourcefulness.

Grammatical Range and Accuracy: Band 5.0

The response contains a noticeable grammatical error right at the start with "The diagram illustrate", where the singular subject 'diagram' lacks the correct third-person singular verb ending. Aside from this error, the grammatical structures used are very simple, consisting mainly of basic active and passive voice constructions in simple sentences. There is a complete lack of complex sentence structures or varied clauses. While the few simple sentences produced are mostly understandable, the range is far too limited and restrictive to meet the criteria for higher bands.
