Band 6.5 vs band 7 essay: the same question, scored side by side
Two answers to one Task 2 question, one scored band 6.5 and one band 7, marked on all four criteria so you can see exactly where the half band goes.
A band 7 IELTS Task 2 sample answer on technology, with the examiner breakdown for all four criteria and what would move it to 8 or drop it to 6.5.
A band 7 answer is not a flawless one. It holds a clear position from the first paragraph to the last, extends every idea it raises, and keeps the majority of its sentences error-free — and the sample below does that on a technology prompt without using a single rare word.
What follows is the question, the answer, and then the marking: one section per criterion, with the specific sentences that earned the band. At the end there is the more useful comparison — what would have taken this essay to 8, and what small changes would have dropped it to 6.5.

What earns the band is not visible in the words — it is the single line of position running from the introduction to the conclusion.
Task 2. Some people say that the widespread use of smartphones has weakened people's ability to communicate face to face. To what extent do you agree or disagree?
Smartphones have changed where conversations happen more than whether they happen at all. I partly agree that constant phone use has weakened face-to-face communication, but the damage is to attention and habit rather than to the underlying ability itself.
The clearest cost is attention. A phone lying on the table competes with the person sitting across it: notifications break the rhythm of an exchange, and even a glance at a screen signals that something more interesting may be available elsewhere. Over time this trains people to accept shallower conversations, and the capacity to sustain a long, unbroken one is the first thing to weaken. Anyone who has watched a family eat a meal with three phones face-up on the table will recognise the pattern.
A second effect is avoidance. Because messaging removes the discomfort of an unrehearsed reply, many people now choose text for exactly the situations that build confidence — complaints, apologies, disagreements. The skill is not lost, but it is exercised far less often, and the lack of practice shows when the conversation cannot be avoided.
The argument is much weaker, however, when it is stated as a general decline. The same devices let people arrange meetings that would once have been impractical, and they hold relationships together across distance until the next meeting happens. Similar predictions were made about the telephone and about television, and both proved exaggerated. What has changed is the default, not the capacity: people who put the phone away still converse perfectly well.
In conclusion, I agree that smartphones have made face-to-face communication harder to sustain, chiefly by fragmenting attention and by offering an easier alternative to difficult exchanges, but I would not accept that the ability itself has been lost.
Word count: 288.
Band 7 Task Response asks for a clear position throughout, main ideas that are extended and supported, and an answer to all parts of the question. Watch what the essay does with "to what extent":
If you consistently score 6.5 on Task 2 despite writing well, this criterion is usually the one holding you there. How to get band 7 in IELTS Writing takes the same four criteria apart as conditions your essay has to meet.
Band 7 CC wants logical progression, clear central topics, and cohesion that does not draw attention to itself. Three things this answer does:
Both criteria sit at 7 here, and it is worth being precise about how low that bar actually is compared with what candidates imagine.
Lexical Resource 7. The essay uses "unrehearsed", "fragmenting attention", "exaggerated", "sustain" — sufficient range with some less common items, used accurately. There is no idiom, no rare academic register, nothing memorised. Band 7 LR rewards flexibility and precision, so one misused impressive word costs more than ten plain accurate ones. The weakest point is "hold relationships together", which is slightly informal for the register; that is the sort of lapse band 7 tolerates.
Grammatical Range and Accuracy 7. There is a mix of forms: a causal subordinate clause ("Because messaging removes the discomfort…"), a relative clause ("Anyone who has watched a family eat a meal…"), and mid-sentence adverbial placement for emphasis ("The argument is much weaker, however, when…"). Band 7 requires a majority of error-free sentences, not all of them. An essay with fifteen sentences and two minor slips that never obscure meaning still sits at 7.
The four criteria are averaged for the Task 2 score, and Task 2 is then weighted against Task 1 for the Writing band: (Task 1 + Task 2 × 2) / 3, rounded in 0.25 steps. That weighting is why a Task 2 criterion left at 6 is expensive. The official criteria are published by IELTS: IELTS Writing band descriptors and key assessment criteria.

Neither direction takes much. One flat opinion sentence drops it a half band; one developed counter-argument raises it.
To 8, the essay would need to be more precise, not longer:
To 6.5, remarkably little would have to change:
Each of those is a one-minute decision under exam pressure, which is exactly why the same writer can produce a 6.5 and a 7 in consecutive attempts. The side-by-side version of that is in Band 6.5 vs band 7 essay: the same question, scored side by side, and the wording the bands above and below are written in runs through the band descriptors post.
Reading model answers has a low ceiling, because the thing that earns the band is invisible on the page — it is the relationship between the position, the paragraphs and the concession, and that does not transfer by imitation. Two things that do work:
And do not copy the question or the phrasing into a real exam answer. Memorised sentences are visible to examiners and are penalised under Task Response, which is the criterion you can least afford to lose.
The reason self-assessment misleads is that writers mark their own grammar strictly and their own task response generously — the argument was clear in your head before it reached the page, so it reads as clear on the page. Marking each criterion separately, as this breakdown does, is what exposes the one that is holding your total down.
Paste your own Task 2 answer, get a band for Task Response, Coherence and Cohesion, Lexical Resource and Grammatical Range separately, and compare the four against the sample above.
Bandly grades your essay or letter against all four criteria and shows the gap to your target band, sentence by sentence.
Two answers to one Task 2 question, one scored band 6.5 and one band 7, marked on all four criteria so you can see exactly where the half band goes.
Task Achievement marks Task 1; Task Response marks Task 2. The official band 6-8 wording for both, side by side, and what each one is actually asking for.
