IELTS Enquiry on Results: what a remark can and cannot do
IELTS Enquiry on Results: the 6-week deadline, why no official success rate exists, why your result is unusable in Japan while the review runs, and the arithmetic to run before you pay.
Your Writing came back 6.0 and you are fairly sure it was a 6.5. An Enquiry on Results is the official way to have that judged again, and every guide to it opens the same way: with a success rate. Thirty to fifty per cent for Writing, twelve to eighteen per cent overall, fifteen to twenty per cent "according to IDP data".
None of those numbers come from a test provider. IELTS, British Council, IDP and Cambridge English publish no figure for how often a remark changes a score, so every percentage you have read is somebody's own count presented as an industry statistic.
That leaves four things you can check for yourself. The fee is not one of them.
What a remark is
IELTS states that "test papers are re-marked by senior Examiners/Markers", and IDP adds that Writing and Speaking remarks are "completed by experienced senior IELTS examiners". Your answers are not re-tested. They are judged a second time, by someone more senior than whoever judged them first.
You can apply "within 6 weeks of the IELTS test date on your Test Report Form", and you can request the remark "for the whole IELTS test or for one or more parts (Reading, Writing, Listening or Speaking)". Listening and Reading are not excluded either, even though those sections are marked against an answer key.
The turnaround is a wide band: IDP says "within 2 hours to 21 days", and IELTS.org gives the same 21-day ceiling. The fee "is fully refunded if your band score changes", and if it does change, your test centre issues a new Test Report Form. IDP is explicit about direction: "Your score does not go down from a remark. So, it will either remain unchanged or increase."
So the downside is not a lower band. It is the money, the wait, and one thing covered further down that costs more than either.
The number nobody quotes, and the one that exists
The IELTS test statistics page publishes three things: test-taker demographics, score distributions, and test reliability. Remark outcomes are not among them. That absence is the whole reason the invented percentages spread.
Two figures on that page are worth more than any of them. The first is a reliability coefficient: comparing original ratings with the "jagged" re-ratings of 2024-2025 performances gave 0.92 for Writing and 0.90 for Speaking. Read the sample before the number. Those re-ratings cover the out-of-line score profiles described below rather than a random draw of every script, so the figure says how closely two examiners agree on the cases most likely to produce disagreement. It is a check on the marking system. It is not a remark success rate wearing a different hat.
The second is a quality check that is easy to walk past on the same page. In the words of the same page, "Cases where one of the examiner-rated sections has been awarded a score that is markedly different to the scores in the Listening and Reading sections are automatically re-marked." A Writing 5.5 sitting under a Reading 8.0 is the shape that check exists to catch, and it runs before the report reaches you. IELTS does not publish what counts as markedly different, so nobody can tell you whether your own paper went through it. What the mechanism does establish is that a remark you pay for is a second opinion on a judgement already screened for outliers, which is a different proposition from catching an obvious mistake.
Run the arithmetic before you pay
A remark can succeed and leave your overall band exactly where it was. Whether that is your situation is arithmetic, and checking costs nothing.
Your overall band is the average of the four sections, rounded to the nearest half band, with .25 rounding up (how the overall band is calculated). A remark is worth paying for when it crosses a rounding line, not when it raises a section.
Take Listening 7.0, Reading 6.5, Writing 6.0, Speaking 6.5. The average is 6.5. Now grant the remark everything you want: Writing 6.0 to 6.5. The average becomes 6.625, which still rounds to 6.5. You would have won the argument and kept the same overall band.
Change one number. Listening 6.5, Reading 6.5, Writing 5.5, Speaking 6.0 averages 6.125 and rounds to 6.0. The same half band on Writing takes the average to 6.25, which rounds up to 6.5. Same complaint, same remark, opposite answer.
The exception is a per-section minimum. "6.5 overall with no band below 6.0" is two requirements, and if the second one is what fails you, the section number is exactly the point and the average no longer matters. Read the offer wording before you decide which situation you are in.
The fee is not the expensive part
In Japan both administrators charge a flat 15,000 yen regardless of how many sections you send. That is not what should worry you.
Eiken states that "while an Enquiry on Results is being processed, your existing result is temporarily invalid", and JSAF puts it in plainer terms still: until the remark result is out, the Test Report Form cannot be used for university or immigration applications. The freeze runs the length of the review, which Eiken describes as roughly three weeks and sometimes longer, and JSAF as two to four.
So if an application deadline falls inside the next month, the decision is already made. A remark that might add 0.5 is not worth missing the deadline that score was meant to meet.
Two more details specific to Japan. The deadlines are not the same at the two administrators: Eiken requires the application within 39 days of the written test date, three days tighter than the six-week rule you will read in English, while JSAF allows six weeks. And both refuse to refund to a foreign account. Eiken states the refund applies only where the score changes and the applicant nominates a Japanese domestic bank account; JSAF says the same in one line, that it cannot refund to an overseas account. Sitting in Japan and leaving before the result arrives is enough to lose the money you were owed.
Remark, One Skill Retake, or sit it again
Three routes, and they are not interchangeable.
| Enquiry on Results | One Skill Retake | Full retest | |
|---|---|---|---|
| What happens | The same answers are judged again | You produce a new performance in one skill | You produce four new performances |
| Deadline | 6 weeks from the test date (39 days with Eiken) | 60 days from the original test | None |
| Requirement | Any IELTS test | Computer-delivered test at a participating centre | None |
| Can the result be worse | No: IDP says unchanged or higher | Yes, but your original Test Report Form stays valid | Yes |
| Results usable meanwhile | No, in Japan | Yes | Yes |
| Turnaround | 2 hours to 21 days | A few days | Weeks, plus the wait for a seat |
The sequencing matters more than the table suggests, and IDP is stricter than six weeks once both routes are in play: "If you want to submit an Enquiry On Results against your original full IELTS test, you must do so within two weeks of your original IELTS Listening, Reading and Writing test date, and wait until you receive your remark status before registering for IELTS One Skills Retake against the same IELTS test."
The day count explains the cutoff. A One Skill Retake has to be sat within 60 days of the original test, and a remark can take 21 of them. Apply on day 13 and even the slowest remark leaves a month to book and sit the retake. Apply on day 40 and it does not.
One caveat before you plan around that. IDP's Australia page says the reverse, that a remark can be lodged on the original test even after a One Skill Retake is booked. Confirm the order with the centre you tested at rather than assuming one rule covers every market.
What to do with the three weeks
Whichever way the remark lands, the thing that produced a 6.0 has not changed, and you have a wait with nothing to submit.
Spend it identifying the criterion rather than revising everything. Writing is marked on four axes, each worth a quarter of that task, and a half band almost always comes from one of them rather than all four (Band Descriptors). Speaking uses its own four. If you cannot say which axis was the 6, a remark is a guess and so is your preparation. The four-axis self-check is how to read your own answer that way.
That naming step is what IELTS Drills automates. Feedback arrives labelled with the axis it belongs to, so a Writing answer comes back as three axes at 7 and Lexical Resource at 6 rather than as one number, and the drilling that follows has a target (five minutes a day). A remark asks someone else to look again. Identifying the axis decides what you do if they say no.
Frequently asked questions
Can a remark lower my score? IDP states that a score "does not go down from a remark", so it either stays the same or rises. The formal appeal that follows a remark is different: Cambridge English says its outcome "may, in turn, lead to the award of a higher result, a lower result, or no result change".
How long does an Enquiry on Results take? IELTS.org says a result can arrive the same day and up to 21 days after the application. In Japan, Eiken advises roughly three weeks and sometimes longer, JSAF two to four weeks.
Do I get the fee back? IELTS states the fee "is fully refunded if your band score changes". In Japan both administrators add the same condition: the refund goes to a Japanese domestic bank account, and neither will send it overseas.
Can Listening and Reading be remarked? Yes. IDP allows a remark "for the whole IELTS test or for one or more parts (Reading, Writing, Listening or Speaking)". Whether it is a sensible use of the fee is another matter, since those sections are marked against an answer key rather than judged (Reading band score, Listening band score).
Remark or One Skill Retake? A remark asks whether your existing performance was judged correctly. A retake replaces it. If you left the room thinking the answer was better than the mark, ask for the remark, and ask early enough that the 60-day retake window survives the wait.
What is the published success rate? There isn't one. No test provider publishes how often a remark changes a score, and the percentages circulating online trace back to third parties rather than to IELTS, British Council, IDP or Cambridge English.
Can I challenge the remark result? JSAF states plainly that no appeal against a remark result is accepted and that it is final. Cambridge English does run an IELTS appeals procedure, which "may not be submitted until an Enquiry on Results has been processed" and which "will not involve re-marking or re-assessment of a test taker's work". It examines whether the procedures were followed. Cambridge adds that further re-marking "might be commissioned as a result of an appeal if it is found that procedures have not been satisfactorily followed", so the route back to a re-mark exists, by way of the process rather than the mark.
The bottom line
Decide it on four checkable things. Does a half band on that section cross a rounding line, or would you win the remark and keep the same overall band? Work that out first, on paper. Is there an application deadline inside the next month? In Japan the result is unusable while the review runs, so a near deadline settles the question by itself. If One Skill Retake is still open, the remark goes in inside two weeks or the two options collapse into one. And if the answer comes back unchanged, you should already know what happens next.
Nobody can tell you the odds, because nobody publishes them. What is knowable is whether the result would help you, and that takes a calculator and ten minutes. With IELTS Drills, the feedback names the Band Descriptor costing you the 0.5, so the next attempt is aimed rather than hoped for, five minutes a day.
