AI examiner evaluation

Task Achievement / Task Response — Band 5.0

The response attempts to cover the main trends in the graph, such as mentioning that UK emissions were high and decreased, Sweden decreased after peaking, Italy increased, and Portugal rose. However, the student's execution suffers from severe data inaccuracies and lack of precision. For instance, Italy's emissions are stated as "4 percent" and "8 percent" instead of metric tonnes, and Portugal's starting figure is given as 1 instead of 1.2 metric tonnes. Furthermore, the overview is extremely basic and lacks a well-developed summary of the overall trends. While all four countries are mentioned, the lack of accurate data handling and weak development place this response at Band 4.5, rounded to 5.0.

Coherence and Cohesion — Band 4.0

The response is divided into two short paragraphs, but the logical organisation and progression are weak. Cohesive devices are extremely basic and repetitive, relying heavily on simple conjunctions like "And" to start sentences (e.g., "And in sweden", "And in italy", "And in portugal"). The flow is frequently disrupted by poor referencing and abrupt shifts between ideas. Paragraphing is also poorly handled, with a lack of clear separation between the introduction/overview and the body details. These features align with the descriptors for Band 4.0.

Lexical Resource — Band 4.0

The lexical range is very limited and repetitive. The student uses basic vocabulary such as "high", "decrease", "reach", and "get to" repeatedly. There are numerous word choice errors and misuse of units, such as measuring carbon dioxide emissions in "percent" instead of metric tonnes ("4 percent" instead of metric tonnes) and non-standard collocations like "carbin dioxide emission per second". Spelling mistakes are frequent (e.g., "emmision", "hih", "carbin"). Because the vocabulary is basic and contains strain-inducing errors, this falls into the Band 4.0 category.

Grammatical Range and Accuracy — Band 4.0

The grammatical range is very limited, consisting mostly of simple and attempted complex sentences that are frequently faulty. There are persistent basic errors in tense consistency (e.g., mixing past events with present tense verbs like "is reach", "is 8.5", "is pass"), missing articles, and subject-verb agreement issues (e.g., "the emmision... is reach to it peak"). Punctuation is also sparse and faulty. The high frequency of grammatical errors impedes readability, placing this performance at Band 4.0.
