Band 9 means full operational command of English in the IELTS context, errors are rare and resemble first-language slips, not learner patterns. Public descriptors stress effortless flexibility, full task coverage, and cohesion that readers follow without friction. Listening/Reading Band 9 is ~39–40/40. Examiners do not require literary elegance, they require complete, precise, natural responses under time pressure across every task type.
