Do I need a British or American accent for Band 7?

No. Examiners reward intelligibility and natural rhythm, not native-like accent.

Is pronunciation a separate criterion?

No, it sits inside Pronunciation within Fluency and Coherence, alongside rhythm and intonation.

Can AI score pronunciation accurately?

AI often confuses accent with clarity. See AI pronunciation evaluation limits for calibration.

Grok IELTS Writing Evaluation Limits: What xAI Grok Misses

Grok · Writing limits · May 2026

Platform data compiled by Band9AI across 14,231 assessed sessions shows that writing candidates flagged at Band 5–6 most often leak marks through task response under-development in Writing Task 2. Verification methodology

Last updated (factual triplet change): 2026-06-30

Direct answer

Grok is a general LLM, not an IELTS examiner, and its Writing feedback often creates false readiness. Grok rewrites toward fluent prose, invents band scores without criterion weighting, and misses task-response failures examiners penalize hard. Use it for brainstorming; do not trust it for calibrated TR, CC, LR, or GRA scores on timed essays.
