IELTS Writing for Candidates stuck at Band 6.5: How to Fix Writing scores that go up and down between attempts
Scores swing when one criterion is much weaker than the others or when the essay changes with the question type. Find the lowest criterion across three or more essays and fix that one first, then practise all question types, not only the one you like.

Why this happens to candidates stuck at Band 6.5
A candidate who is strong on opinion essays and weak on two-part questions will score well or badly depending on the topic type. Mixed practice reveals which criterion drives the swings.
Why this affects candidates stuck at Band 6.5: practice is broad when it should target the single weakest criterion.
Ideas are developed in one paragraph and thin in the other.
A strength to build on: Most criteria are already close to Band 7, so one fix can lift the result.
Fix it in four steps
- Collect three or four recent essays of different question types and score each criterion separately against the band descriptors.
- Find the criterion that is lowest in most of them. That is your main target.
- Practise the question type you avoid until your score on it matches the others.
- Re-test with a new essay after two weeks and compare criterion by criterion, not only the overall band.
Before and after
Before
Band 7 on one opinion essay, Band 6 on a two-part question, no idea why.
After
Task Response is the weakest in both, because the second question part is under-developed.
Ten-minute drill: Write one essay per question type this week (opinion, discussion, problem-solution, two-part) and tag the weakest criterion in each.
Questions and answers
How can candidates stuck at Band 6.5 fix Writing scores that go up and down between attempts?
Scores swing when one criterion is much weaker than the others or when the essay changes with the question type. Find the lowest criterion across three or more essays and fix that one first, then practise all question types, not only the one you like. Ideas are developed in one paragraph and thin in the other.
How long does it take candidates stuck at Band 6.5 to fix Writing scores that go up and down between attempts?
Most learners need three to four weeks. Two to four weeks of targeted practice on the lowest criterion is a realistic window.
Is it normal for the same candidate to score differently on different days?
Some variation is normal because topics and examiners differ. Large swings usually point to a weak criterion or an untrained question type that practice can fix.
How many essays do I need to see a pattern?
Three to five essays across different question types are enough to show which criterion is repeatedly lowest.
What does a good practice drill look like for candidates stuck at Band 6.5?
Write one essay per question type this week (opinion, discussion, problem-solution, two-part) and tag the weakest criterion in each. Two to four weeks of targeted practice on the lowest criterion is a realistic window.
How can candidates stuck at Band 6.5 tell they have fixed Writing scores that go up and down between attempts?
Your criterion scores stay within half a band of each other across three different question types.
What should candidates stuck at Band 6.5 know about their IELTS Writing target?
At Band 6.5, one criterion is usually holding the score back. Finding it matters more than more general practice.
Should candidates stuck at Band 6.5 practise this on Task 1, Task 2 or both?
It shows up in both tasks. Fix it in Task 2 first, because Task 2 carries about twice the weight of Task 1, then check Task 1 with the same checklist. Most criteria are already close to Band 7, so one fix can lift the result.
