Band Descriptors Across All Four IELTS Skills: One Clear Map

Bands & Scores29 August 2026 · 7 min read · WiderAI Team

IELTS band descriptors are the published criteria examiners use to award bands from 0 to 9 — but they only exist for two of the four skills. Speaking and Writing are judged by trained examiners against four criteria each; Listening and Reading have no descriptors at all, because they are marked objectively: 40 questions, each right or wrong, with your raw score converted to a band.

That single distinction explains most of the confusion candidates have about IELTS scoring. When people search for "band descriptors", they usually want one table covering everything, and no such table exists — because half the test is judged and half is counted. Once you see the exam that way, preparation becomes much clearer: for Listening and Reading you need accuracy and technique; for Speaking and Writing you need to satisfy four named criteria, each worth a quarter of your band.

Here is the whole map in one place: what each skill is scored on, how the numbers combine into your overall band, and what to do differently once you understand the system. The official descriptor documents themselves are available through ielts.org; what follows is the plain-English version of what they reward.

How are Speaking and Writing scored?

Both productive skills use four equally weighted criteria. The examiner assigns a whole band for each criterion, and the four are averaged into your skill band.

Speaking's four criteria:

• Fluency and coherence — can you speak at length, at a natural pace, without long searching pauses, and do your ideas connect logically? Hesitating to think of ideas is human; hesitating to find words and grammar is what costs bands.
• Lexical resource — the range and precision of your vocabulary, including less common words used accurately, natural collocation, and the ability to paraphrase when a word escapes you.
• Grammatical range and accuracy — a mix of simple and complex structures used correctly. Range without accuracy fails, and so does accuracy achieved by hiding in short simple sentences.
• Pronunciation — how easily a listener understands you, including sounds, word stress, sentence stress and intonation. Accent is not marked; intelligibility is.

Writing's four criteria:

• Task achievement (Task 1) / Task response (Task 2) — did you fully do the specific job the question set: cover all parts of the question, take a clear position, support ideas properly, meet the word count?
• Coherence and cohesion — logical paragraphing, clear progression from sentence to sentence, and linking that guides the reader without mechanical overuse of connectors.
• Lexical resource — as in Speaking, with spelling and word formation also in play.
• Grammatical range and accuracy — variety and correctness of structures, including punctuation.

Because each criterion counts equally, an uneven performance drags you down mathematically: brilliant vocabulary cannot rescue an essay that never answers the question. The most efficient gains almost always come from your weakest criterion, not from polishing your strongest. If Speaking is your battleground, we break each criterion down band by band in speaking band descriptors explained.

How are Listening and Reading scored without descriptors?

Listening and Reading each contain 40 questions worth one mark each, with no penalty for wrong answers. Your raw score out of 40 converts to a band using a conversion set by the test makers. The conversion can vary slightly between test versions to keep difficulty fair, and in Reading the Academic and General Training papers convert differently — General Training requires more correct answers for the same band, because its passages are less demanding.

The practical consequences:

1. Never leave a blank. A guess costs nothing and might score.
2. Every question is equal. A stubborn matching-headings item is worth exactly as much as an easy gap-fill. Spending four minutes on one question is a scoring error, not persistence.
3. Precision counts as much as comprehension. Misspelt answers, answers over the word limit, and answers copied into the wrong space all score zero, however well you understood the passage. A surprising share of "reading problems" are actually transfer-and-accuracy problems.
4. Progress is measurable. Unlike Writing and Speaking, you can track raw scores weekly and watch the trend. Around 30 out of 40 in Academic Reading typically corresponds to roughly band 7 — check a current conversion guide, then benchmark yourself honestly under timed conditions.

There are no style points here, no examiner impressions, nothing to persuade. The whole game is right answers under time pressure, which is why technique — skimming, locating, recognising paraphrase — improves these bands faster than general English study once you are past intermediate level.

How do the numbers become your overall band?

Three layers of arithmetic connect your performance to the score on your Test Report Form:

1. Within Speaking and Writing: the four criterion bands are averaged into the skill band.
2. Within Listening and Reading: raw score out of 40 converts to the skill band.
3. Overall: the four skill bands are averaged, then rounded to the nearest half band — and the rounding is generous: an average ending in .25 rounds up to the next half band, and one ending in .75 rounds up to the next whole band.

So Listening 6.5, Reading 6.5, Writing 6.0, Speaking 7.0 averages to 6.5 overall. But Listening 7.0, Reading 7.0, Writing 6.5, Speaking 6.5 averages to exactly 6.75 — which rounds up to a 7.0 overall, even though two skills sit at 6.5. Calculate this precisely for your own target combination, because it changes strategy: sometimes the cheapest route to your overall band is half a band in your strongest skill, not your weakest.

Remember also that many universities and visa routes set minimums per skill as well as an overall band. In that case the arithmetic stops mattering and every listed skill must independently clear its bar.

What should you do differently now?

Turn the scoring map into a preparation plan:

• Diagnose per criterion, not per skill. "My Writing is 6.0" is not actionable; "my task response is 5 while my grammar is 7" is. The fix for the first criterion is reading the question harder, not learning more tenses.
• Split your study time by marking type. Judged skills improve through feedback loops: produce, get criterion-level marking, fix one weakness, repeat. Counted skills improve through timed drilling and error logs: which question types, which paraphrase traps, which careless transfers.
• Rehearse the real conditions. Examiner judgement includes how you perform under pressure, and timing errors only show up under a clock. A scored IELTS speaking mock test with criterion-by-criterion feedback tells you in twenty minutes what months of unmarked practice cannot.
• Read the official documents once. The public descriptor documents on ielts.org repay one careful reading — not to memorise, but so nothing an examiner rewards ever surprises you again.

The band descriptors are not a secret code; they are a published contract. Candidates who read the contract and train against it, criterion by criterion, reliably outpace candidates who simply "do more English" and hope the number moves.
