BAND9AI evaluates Task 2 against the four public Writing criteria—Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy—each with its own band and quoted evidence from your timed essay. The system checks prompt coverage first (did you answer every part?), then paragraph logic, vocabulary precision, and error density. Overall band follows IELTS weakest-link logic across the four scores—not a single "sounds fluent" label from chat.
