Band 5+: The pie charts illustrate the proportion of graduates with different levels of qualifications in science and art working in a specific engineering company between 1980 and 2008.

The report addresses the main trends and provides a comparison between the two years, which is the primary requirement of the task. The overview identifies the most significant changes and the most stable category. However, there are some inaccuracies in the data presentation; for instance, the report states that Ph.D. Science replaced Master Science as the most proportion of graduates, but the data shows they are very close (30% vs 29%), and the phrasing is slightly awkward. To improve, ensure that all comparisons are mathematically sound and work on using more precise academic vocabulary to describe trends (e.g., 'remained constant' instead of 'was the most steady'). Additionally, ensure that the distinction between 'amount' and 'proportion' is maintained, as the charts show percentages, not absolute numbers. The report falls short of the required 150 words.

The report follows a logical structure, but the progression of ideas is hindered by fragmented sentences. For instance, the sentence starting with 'While Ph.D Science...' is a dependent clause that lacks a main clause, which disrupts the flow. To improve, ensure that every sentence is a complete thought and use a wider variety of cohesive devices (e.g., 'In contrast,' 'Regarding,' 'Conversely') to link your observations more smoothly.

The vocabulary is somewhat repetitive and occasionally used incorrectly. For example, 'the most steady' and 'the most proportion' are unnatural collocations. Instead of 'the most steady,' you could use 'remained stable' or 'showed little change.' Additionally, try to vary your descriptors for change (e.g., 'remained constant,' 'experienced a decline,' 'witnessed an upward trend') to avoid repeating the same terms. Boost vocabulary complexity to elevate the overall score.

There are several grammatical issues that impact clarity, particularly regarding subject-verb agreement (e.g., 'Ph.D Science and Ph.d Art is increasing' should be 'are increasing') and sentence structure. There are also issues with noun usage, such as 'the remaining three graduates' (which refers to people rather than the proportions/categories). Focus on mastering complex sentence structures and ensuring that your subjects and verbs always agree in number.
