Why this response received Band 5.5
The response covers every cause and correctly highlights unskilled teachers and upbringing as the two largest shares, giving it a recognizable overview. Its main limitation is unreliable precision, especially the incorrect figure for poor facilities, alongside frequent grammatical awkwardness; the highest priority is to verify each category and percentage and present the comparisons in shorter, accurate sentences.
IELTS Writing Criteria Scores
Task Achievement
The main features and all five categories are addressed, but poor facilities is incorrectly reported as 18% rather than 10% and comparisons remain limited.
Check every percentage against the chart and compare the largest, middle, and smallest causes directly rather than listing them separately.
Coherence and Cohesion
The overview and detail paragraphs create a generally clear sequence, although repetitive framing and awkward connectors make the progression mechanical.
Organize the figures into ranked groups and use concise comparative links instead of repeatedly introducing each item as another reason.
Lexical Resource
The vocabulary is adequate for the topic, but repetition of reason and inaccurate expressions such as inexpert teachers and reason outcome limit control.
Use precise chart language such as accounted for, proportion, leading cause, and smallest share while avoiding forced synonyms.
Grammatical Range and Accuracy
Frequent problems with agreement, articles, possessives, and clause construction occur throughout, though the main meaning is usually recoverable.
Prioritize accurate subject-verb agreement and complete sentence patterns when reporting each category and its percentage.
