IELTS Speaking 6 to 7: what is holding you back

Mr. Jay Adams (CELTA) · 13 October 2026 Checked against the band descriptors on ielts.org on 13 October 2026. Jurassic English™ is independent and not affiliated with British Council, IDP or Cambridge University Press & Assessment. This is a teacher's advice, not official IELTS guidance.

Key facts

  • The Speaking score comes from four equally weighted criteria: Fluency and Coherence, Lexical Resource, Grammatical Range and Accuracy, Pronunciation.
  • The gap between band 6 and band 7 is about ease and flexibility: band 6 can speak at length; band 7 speaks at length without visible effort.
  • The four criteria interact: the visible problem is often a symptom.
  • The Jurassic English method: find one primary constraint, show the evidence in your own answers, keep your strengths, practise a structure of thinking rather than memorised answers, then re-measure.
  • No one can promise a band. This guide does not promise 7.0, and Jurassic AI Speaking scores are practice estimates, not official results.

Many learners reach me at 6.0 or 6.5 with the same story: lots of vocabulary study, no movement in the score. They are usually fixing several things at once, when the score is held down by one.

The four criteria and the public descriptors

IELTS publishes its Speaking Band Descriptors on ielts.org. Its "IELTS scoring in detail" page says the four criteria carry equal weight and the Speaking score is their average; rounding rules are explained there.

Two notes at the foot of the descriptors matter most. To get a band on a criterion, you must fully fit that band's positive features. And you are rated on your average performance across all parts of the test. That is why "a bit more of everything" rarely moves the score.

Band 6 vs band 7, criterion by criterion

My paraphrase of the public descriptors, not an official version:

Criterion Band 6 Band 7 What changes
Fluency and Coherence Happy to talk at length, but the thread sometimes breaks when you pause, repeat yourself or restart a sentence. Linking words are there, sometimes in the wrong place. Long turns come "without noticeable effort". You may still pause mid-sentence to find a word, but the listener never loses the thread, and you move between ideas smoothly. Hesitation is still allowed at 7. Losing the thread is not.
Lexical Resource You have the words to keep talking about most topics; some choices sound slightly off, yet the meaning gets through, and you can usually say it another way. You adapt your vocabulary to each topic, reach for some less common words and natural word partnerships, and still slip occasionally. Rephrasing works when you need it. Not "harder words" but choosing words to fit the context.
Grammatical Range and Accuracy You try complex sentences, but they often carry mistakes, and your choice of structures feels fixed; listeners still understand you. You move between simple and complex sentences without strain; most sentences come out clean, though a few errors, even basic ones, can remain. Clean sentences become the norm. Band 7 still allows errors.
Pronunciation Mostly easy to follow, with control that comes and goes: stress and intonation work for a while, then fade, and a few words are unclear. No standalone band 7 descriptor. Band 7 means everything positive at band 6, plus part of what band 8 shows: steady rhythm and flexible intonation over long turns, easy to understand throughout. Keep band 6 stable, then sustain rhythm across longer turns.

An ielts.org article (3 December 2025) makes a similar point: at 6 a speaker states opinions; at 7 they build arguments.

Why the criteria interact

  1. Grammar search breaks fluency. You stop mid-sentence to choose a verb form. It looks like a fluency problem; the root is a structure you know but cannot yet produce automatically.
  2. Short ideas make vocabulary look narrow. One claim and one vague reason leave no room for less common words.
  3. Memorised phrases hurt coherence. Long openers and inserted idioms sound smooth, then fail to match what follows.
  4. Pronunciation is fine, but fluency is the limit. Speech chopped into fragments gives stress and intonation no long sentence to run across.

The method: one primary constraint

  1. Find one constraint. Ask: "If I could fix only one thing in the next six weeks, what would lift the most criteria?"
  2. Show the evidence. Record three Part 3 answers, transcribe them, and mark where each hesitation falls (between ideas, or mid-sentence before a verb), how many real ideas each answer has, and where errors cluster.
  3. Keep your strengths. Note what stays the same as well as what changes.
  4. Practise structure, not memorised answers. A sequence of thinking (claim, reason, example, consequence) works on any topic.
  5. Re-measure. After two or three weeks, record new questions and mark the same indicators.

Three illustrative examples

Invented to explain the method; not real student answers, not models to memorise.

Illustrative example 1: grammar breaking fluency. Asked whether people read less than in the past, suppose you say: "I think... people nowadays, they are... they have... um, they have been reading less, because of the phone... it make people... not focus." Every pause sits just before a verb. The constraint is an unautomated structure, not fluency itself. Say the idea in a structure you control first, then drill the present perfect across many topics.

Illustrative example 2: short ideas, narrow vocabulary. Asked how technology has changed work, suppose you say: "Technology makes work easier. People can work at home. It is very convenient." Three sentences, one idea. Develop it: "Many office jobs can now be done remotely, so people skip the daily commute. The downside is that work time and family time get blurred." Remotely, commute and blurred appear because the idea needs them.

Illustrative example 3: memorised phrases, lost coherence. Asked whether you enjoy cooking, suppose you say: "Well, that's a really interesting question. In my humble opinion, cooking is a double-edged sword. I don't cook very often because I live with my parents." The idiom matches nothing that follows. Answer directly: "Not really. My mum does most of the cooking, so I only make simple things like fried rice."

FAQ

What does band 7 in IELTS Speaking require? Ease and flexibility across all four criteria, with some errors and hesitation still allowed. You need to fully fit band 7's positive features on a criterion to get band 7 on it.

How long does it take to go from 6.0 to 7.0? No one can answer honestly before hearing you, and practice gains are not a promise about the test.

Should I memorise model answers? No. Practise a sequence of thinking instead.

Is pronunciation the most important criterion? The four criteria are weighted equally. Check your own evidence before spending months on individual sounds.

Is a Jurassic AI Speaking score an IELTS score? No. It is an AI practice estimate with an uncertainty range. Typed answers cannot be assessed for pronunciation.

Is Jurassic English linked to British Council, IDP or Cambridge? No. Jurassic English™ is independent, and this advice is unofficial.
