EssayHero was built with HKDSE students in mind, but the feedback system works just as well for IELTS preparation. This post explains how EssayHero handles IELTS essays and how the feedback maps to official band descriptors.
Understanding IELTS Writing Assessment
IELTS Writing is marked on four criteria, each worth 25% of your score:
| Criterion | What Examiners Look For |
|---|---|
| Task Response (Task 2) or Task Achievement (Task 1) | Did you answer the question fully? Is your position clear? Are your ideas developed? |
| Coherence & Cohesion | Is your essay well-organised? Do paragraphs flow logically? Are linking words used appropriately? |
| Lexical Resource | Do you use a wide range of vocabulary? Is word choice precise? Can you paraphrase effectively? |
| Grammatical Range & Accuracy | Do you use varied sentence structures? Are there errors, and do they impede communication? |
EssayHero analyses your essay against all four criteria and provides a band estimate for each, along with paragraph-by-paragraph feedback.
Task 1 vs Task 2: Different Requirements
IELTS Writing includes two tasks with different requirements. EssayHero handles both.
Task 1: Data Description (150 words minimum)
Task 1 asks you to describe visual information: graphs, charts, tables, diagrams, or maps.
You're not giving your opinion. You're summarising and comparing data.
What EssayHero checks
- Overview statement — the big picture that summarises the main trend
- Key features identified and compared — selective, not exhaustive
- Data accuracy — if specific figures mentioned
- Appropriate academic tone — objective, not personal
- Vocabulary for describing trends — rises, falls, fluctuations, comparisons
Common Task 1 mistakes EssayHero catches
- Missing overview paragraph — examiners expect this upfront
- Listing every data point — select key features instead
- Using "I think" or opinion language — Task 1 is descriptive only
- Inaccurate descriptions of trends — check your interpretation matches the data
Task 1 Pro Tip
Write your overview first. It forces you to identify the most important trends before you get lost in details.
Task 2: Essay (250 words minimum)
Task 2 is an academic essay responding to a statement, question, or argument.
You need to present a clear position supported by reasons and examples.
What EssayHero checks
- Clear thesis statement — your position stated explicitly
- Position maintained throughout — no contradictions
- Relevant supporting points — each paragraph develops your argument
- Logical paragraph structure — one main idea per paragraph
- Appropriate conclusion — summarises without introducing new points
Common Task 2 mistakes EssayHero catches
- Sitting on the fence — "both sides have merit" without taking a position
- Body paragraphs that don't support the thesis — off-topic development
- Conclusions that introduce new arguments — summarise only
- Underdeveloped ideas — assertions without explanation or examples
How EssayHero Maps to Band Descriptors
When you submit an IELTS essay, EssayHero analyses each paragraph against the official band descriptors published by the British Council.
Detailed, actionable feedback
EssayHero doesn't just give you a number. It explains why you received that band and what's holding you back from the next level.
For example, if you receive Band 6 for Coherence & Cohesion, the feedback will explain why:
Your essay shows clear overall progression, with each paragraph addressing a distinct point. However, some cohesive devices are mechanical ("Firstly... Secondly... Thirdly...") and there are occasional lapses in paragraphing. More sophisticated linking and clearer referencing would lift this to Band 7.
This specificity helps you understand not just your current level, but what's needed to improve.
What the Band Scores Mean
| Band | Description | What It Takes to Get There |
|---|---|---|
| 9 | Expert | Fully addresses all parts with fully developed position. Rare minor errors only. |
| 8 | Very Good | Sufficiently addresses all parts with well-developed response. Wide range of structures with only occasional errors. |
| 7 | Good | Addresses all parts clearly. Uses a range of vocabulary and structures flexibly. Good control overall. |
| 6 | Competent | Addresses all parts adequately. Adequate vocabulary with some errors. Mix of simple and complex structures. |
| 5 | Modest | Addresses the task only partially. Limited vocabulary. Frequent errors that may cause difficulty. |
Most university programmes require Band 6.5 or 7.0 overall. EssayHero helps you understand where you stand on each criterion and what specific improvements would push you higher.
Understanding Your Target Band
Check your university requirements early. Some programmes accept Band 6.5, others require 7.0 or higher. Your preparation strategy changes depending on your target.
Using EssayHero for IELTS Prep
Here's how I'd recommend using EssayHero as part of your IELTS preparation.
1. Practise under timed conditions
Write your essay in the time allowed (20 minutes for Task 1, 40 minutes for Task 2), then submit for feedback.
The time pressure is part of the skill you're developing. Don't skip this step.
2. Focus on one criterion at a time
If your Lexical Resource is consistently lower than your other scores, spend a week focused on vocabulary.
Try to use new words in each practice essay. Track whether your band for that criterion improves.
3. Track patterns across essays
If EssayHero keeps flagging the same issue (weak conclusions, limited sentence variety, unclear thesis), that's your priority area.
Recurring feedback tells you where to invest your effort.
4. Use the feedback for revision
Don't just read the feedback and move on.
Revise your essay based on the suggestions, then submit the revised version. Compare the two sets of feedback to see if your changes worked.
5. Check your teacher's judgement too
AI feedback is useful but imperfect.
If you have access to a teacher or tutor, show them your essay and the AI feedback. Their human judgement adds context that AI can't provide.
Key Takeaways
Effective IELTS practice with EssayHero:
- Write under timed conditions (Task 1: 20 min, Task 2: 40 min)
- Focus on one weak criterion per week
- Track recurring issues across multiple essays
- Revise and resubmit to test improvements
- Combine AI feedback with human teacher review
Limitations to Keep in Mind
EssayHero provides estimates, not predictions.
IELTS examiners are human, and they apply professional judgement that AI cannot replicate. Your actual exam score may differ from EssayHero's estimates.
Knowledge cutoff
The AI also has a knowledge cutoff. If you write about very recent events, the AI might not recognise them.
For Task 2 topics about current affairs, be aware that some of your examples may not be evaluated as accurately.
Use as Practice, Not Prediction
EssayHero is a practice tool, not a prediction service. Treat the band estimates as directional feedback, not guaranteed exam scores.
A useful tool in your preparation toolkit
Despite these limitations, EssayHero provides useful practice feedback that many IELTS candidates otherwise don't have access to.
Use it as one tool among several in your preparation.
