Most candidates do not need to memorise every word of the descriptor. They need to know which criterion is blocking the next band and what kind of revision changes that criterion.
The answer addresses the task, but some parts may be underdeveloped, unclear, or too general.
The answer covers the task clearly, gives a position where needed, and develops the main ideas enough.
The answer handles the task fully, extends ideas well, and deals with the prompt in a precise way.
Practical fix: Check whether every paragraph directly answers the exact question, not just the broad topic.
The answer has an overall structure, but paragraphing, progression, or linking may feel mechanical.
Ideas progress logically, paragraphs have clear roles, and cohesive devices are usually controlled.
The answer is easy to follow throughout, with natural cohesion and very clear paragraph management.
Practical fix: Make each topic sentence name one idea, then develop only that idea before moving on.
Vocabulary is sufficient for the task, but word choice may be repetitive, vague, or sometimes inaccurate.
Vocabulary shows range and some flexibility, with less common words used mostly appropriately.
Vocabulary is precise and flexible, with strong collocations and only occasional awkward choices.
Practical fix: Replace vague words with topic-specific nouns and verbs, not random synonyms.
The answer uses a mix of simple and complex sentences, but errors still reduce control or clarity.
The answer uses a variety of complex structures, and most sentences are error-free or easy to understand.
Grammar is flexible and accurate, with a wide range of structures and only rare slips.
Practical fix: Prioritise accurate complex sentences over long sentences that hide several grammar errors.
How to use the descriptors on your own essay
The fastest improvement usually comes from applying the descriptors to one draft at a time, not from reading them passively.
Score each criterion separately before estimating the overall band.
Find the lowest criterion and rewrite one paragraph for that criterion only.
Compare your rewrite against a sample answer for the same task type.
Run the revised draft through the checker to see whether the same weakness remains.
IELTS Writing band descriptor FAQs
Are IELTS Writing band descriptors the same for Task 1 and Task 2?
They use the same four broad scoring areas, but Task 1 uses Task Achievement and Task 2 uses Task Response. The details differ because Task 1 describes visual or letter information, while Task 2 develops an argument.
What is the main difference between Band 6 and Band 7 in IELTS Writing?
Band 7 usually requires clearer task coverage, better paragraph progression, more flexible vocabulary, and more frequent error-free sentences. Many Band 6 answers communicate meaning but lack control and development.
Can an AI checker replace the official IELTS band descriptors?
No. The official descriptors are the reference point. A checker can help you apply the criteria to your draft and find likely weaknesses, but your real exam score is decided by IELTS examiners.
