The image shows a line graph titled "Trends in science, reading and mathematics performance" with subtitle "PISA score points, OECD Average". The vertical axis measures scores from 460 to 510 in increments of 5, and the horizontal axis spans the years 2006, 2009, 2012, 2015, 2018, 2022, and 2025. Three subjects are tracked in the legend: Science, Reading, and Mathematics. For Science, data points are 503 in 2006, 506 in 2009, 505 in 2012, 491 in 2022, and 486 in 2025. For Reading, data points are 495 in 2006, 499 in 2009, 501 in 2012, 497 in 2015, 493 in 2018, 482 in 2022, and 466 in 2025. For Mathematics, data points are 501 in 2006, 502 in 2009, 496 in 2018, 480 in 2022, and 469 in 2025.

The line chart illustrates science, reading, and mathematics performance from 2006 to 2025, measured in PISA score points according to the OECD average.

Overall, the given chart highlights significant variations in the three trends over the period, where, science recorded the highest score in 2009, while mathematics and reading recorded the lowest score in 2025, respectively.

In 2006, science had the highest score at 503, followed by mathematics at 502, and reading with 495. After that, science and mathematics decreased from 506 and 502 in 2009 to 505 and 499 in 2012, while reading rose from 499 to 501 by the same year. Science, mathematics, and reading declined significantly to 497 in 2015, while mathematics remained unchanged in 2018.

On the other hand, science, mathematics, and reading decreased from 496 and 493 in 2018 to 486, 469, and 466 in 2025, respectively.

Task Response

The report effectively identifies the overall trends and makes some comparisons between the subjects. However, there are a few inaccuracies and omissions in the data, such as the mention of mathematics at 502 in 2006 (should be 501) and the description of reading rising to 501 in 2012 (which is correct, but the preceding data points for reading in 2009 and 2012 are slightly misstated). Additionally, the report omits some key data points, like science in 2015 and 2018, and reading in 2022. To improve, ensure all main features are covered accurately and avoid minor data errors. The structure is clear, but the overview could be more precise by highlighting the overall decline in all subjects towards the end of the period. The report falls short of the required 150 words.

Coherence & Cohesion

The report is well-structured and easy to follow, with a clear overall trend description and a logical progression through the time periods. The use of cohesive devices like 'Overall', 'After that', and 'On the other hand' helps guide the reader. However, the paragraphing could be slightly improved for better flow, and some transitions between sentences feel a bit abrupt. Consider using more varied linking phrases to enhance cohesion.

Lexical Resource

The vocabulary is appropriate and generally accurate, with good use of terms like 'significant variations', 'declined significantly', and 'remained unchanged'. However, there is some repetition (e.g., 'score' used multiple times) and a few imprecise choices (e.g., 'respectively' is used awkwardly at the end of the first paragraph). To improve, incorporate a wider range of synonyms and more sophisticated lexical items, such as 'fluctuations', 'peaked', or 'plummeted'. Pay attention to vocabulary repetition to improve the overall score.

Grammatical Range & Accuracy

The grammar is largely accurate, with a good mix of simple and complex sentence structures. The report uses tenses correctly (past for historical data, present for trends) and punctuation is mostly appropriate. There are no major errors, but a few minor issues exist, such as the awkward phrasing 'while mathematics remained unchanged in 2018' (which could be clearer) and the use of 'respectively' without a clear list. Overall, the grammatical control is strong and does not impede understanding.
