How BAND9AI Evaluates IELTS Writing Task 2
Writing Task 2 · Rubric scoring · May 2026
Direct answer
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.
The four criterion pass
TR Position, prompt coverage, idea development
CC Paragraphing, progression, referencing
LR Precision, collocations, less common items
GRA Range, error frequency, meaning impact
Evaluation steps on your essay

| Descriptor match | Each criterion anchored to public band language |
| Evidence quotes | Sentences flagged for TR leaks, CC jumps, LR misuse |
| Weakest link | Lowest criterion explains the cap |
