Task Achievement / Task Response — Band 4.0
The response is severely under-length, containing only 86 words against the required minimum of 150 words. Consequently, the description of the nine-step bamboo manufacturing process is incomplete and underdeveloped. While the student attempts to outline the stages, the sequence is partially confused, with step 6 (softening) placed before step 5 (filtering) and step 4 (crushing). An overall summary is attempted at the very end, but due to the restricted length and omission of key comparative features, the response only partially addresses the prompt, earning a band score of 4.0.
Coherence and Cohesion — Band 4.0
The text lacks proper paragraphing, presented as a single short block of text. Cohesive devices are extremely basic and repetitive, relying heavily on sequential connectors like 'first', 'In second step', and 'then'. The logical progression of the process is disrupted by the incorrect ordering of the steps, as the student describes crushing the strips after filtering and softening. Because information and ideas are not arranged coherently and referencing is faulty, the response aligns with band 4.0.
Lexical Resource — Band 4.0
The vocabulary used is very basic and repetitive, featuring frequent spelling errors such as 'frabic' for fabric, 'manfacture' for manufactured, 'sperate' for separate, and 'yam' for yarn. While some process-related terms are attempted ('strips', 'liquid pulp', 'fibres', 'yarn'), the persistent spelling mistakes and limited lexical range restrict the score. The inadequate range and frequent slips that cause some difficulty for the reader place this response at band 4.0.
Grammatical Range and Accuracy — Band 4.0
The response shows a very limited range of grammatical structures, consisting mainly of simple sentences with frequent missing articles, incorrect verb forms, and tense inconsistencies ('the plant named bamboo was grow there', 'its harvest in Autum season', 'It soft the fibres'). Punctuation and capitalization are frequently neglected at sentence boundaries. These pervasive errors and the lack of complex sentence control mean the grammar corresponds to a band 4.0.
