Feedback from a certified IELTS examiner or CELTA-qualified trainer provides the gold standard of Writing assessment. Human evaluators can apply contextual judgement — understanding register, cultural nuance, and exam-day intent in ways that require interpretation.
- Certified examiner judgement calibrated to real exam marking
- Nuanced feedback on tone, register, and argumentation strategy
- Personal guidance on how to restructure specific paragraphs
- Best used before your exam for a final professional review

AI evaluation makes the high-frequency feedback loop that builds Band 7+ writing accessible to every candidate. Instead of waiting days for feedback on two essays a week, you receive detailed criterion-level scores and inline annotations in under 30 seconds — unlimited times.
- Band scores for all 4 criteria in under 30 seconds
- Inline annotations — every grammar error and vocabulary gap highlighted
- Consistent application of official band descriptors every session
- Track progress across all evaluations in your personal dashboard

Our AI Evaluator Methodology
Our evaluator is not a general-purpose grammar checker. It is specifically trained on the official IELTS Writing band descriptors published by Cambridge Assessment English. Every essay is assessed against the same four criteria used on exam day:
Task Achievement (Task 1) / Task Response (Task 2)
Does the response address all parts of the task? Is the position clear and fully developed?
Coherence and Cohesion
Is the essay logically organised? Are ideas sequenced clearly with appropriate linking devices?
Lexical Resource
Is vocabulary varied, precise, and used correctly? Are there paraphrases and topic-specific terms?
Grammatical Range and Accuracy
Is there a range of complex structures? Are errors frequent enough to impede communication?

Frequently Asked Questions
Is AI IELTS evaluation accurate?
AI evaluation trained on official IELTS band descriptors produces band score predictions closely aligned with certified examiners — typically within 0.5 bands. The accuracy is highest when the essay is written under realistic conditions and the question prompt is included. Our evaluator is specifically calibrated to IELTS Writing, not generic text quality.
How does AI grade IELTS Writing essays?
Our AI evaluator analyses your essay against the four official IELTS marking criteria: Task Achievement (or Task Response for Task 2), Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. Each criterion is scored on the 0–9 band scale, and the system identifies specific words, sentences, and structural patterns that are affecting each score.
How much does human IELTS examiner feedback cost?
Feedback from a certified IELTS examiner or CELTA-qualified Writing coach typically costs £20–£60 per essay. Turnaround ranges from 24 hours to one week. By comparison, AI evaluation starts from £4.99 per essay with results in under 30 seconds.
Can AI replace a human IELTS examiner?
AI evaluation is highly effective for the feedback loop that most candidates need — identifying recurring errors across the four criteria and tracking band progress. However, human examiners provide nuanced contextual judgements and can evaluate Speaking. The ideal approach is frequent AI evaluation for Writing practice, supplemented by a human trainer review before your exam.
How is the IELTS band score calculated?
In Writing, four criteria are each scored on a 0–9 scale: Task Achievement/Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy. The four scores are averaged (rounded to the nearest half band) to produce your Writing band. This band is then averaged with your Listening, Reading, and Speaking bands to produce your overall band score.
