Band 6 is the requirement for most undergraduate courses and a great many visa routes, which makes this the most consequential half-band on the scale. It is also the one with the least written about it — almost every guide online is aimed at people trying to reach 7.
That matters more than it sounds, because the advice does not transfer. Band 7 guidance tells candidates to take risks with unusual vocabulary and complex structures. Given to someone sitting at 5, that advice makes them slower, less accurate and harder to follow — it moves them away from 6, not towards it.
Fluency & Coherence
Flow, speed, hesitation, and how logically ideas connect.
At band 5
Willing to speak at length even when coherence slips, and able to keep going through hesitation rather than stopping.
At band 6
At band 5 the speech is usually there but it stalls — long pauses, restarts, and a reliance on the same few connectives.
What to practise
Length before polish. Answer every question with at least two sentences even when the second one is imperfect; a rough sentence scores and a silence does not.
Lexical Resource
Range and precision of vocabulary, paraphrasing, and collocation.
At band 5
Enough vocabulary to discuss any familiar topic, with paraphrase attempted when the exact word is missing.
At band 6
Band 5 has the words for familiar topics but stops dead when the topic moves, and rarely attempts to talk around a gap.
What to practise
Practise paraphrase explicitly. When you cannot find the word, describe the thing — 'the place where you wait for trains' scores; a five-second silence does not.
Grammatical Range & Accuracy
Variety of structures and how error-free they are.
At band 5
A mix of simple and complex sentences, with frequent errors in the complex ones that rarely block understanding.
At band 6
Band 5 leans almost entirely on simple sentences, and the errors in the few complex attempts do sometimes obscure the meaning.
What to practise
Add one clause. 'I moved here in 2019' becomes 'I moved here in 2019, which was when my sister started university'. One relative clause per answer changes the band.
Pronunciation
Clarity and intelligibility measured from your spoken audio.
At band 5
Generally understood throughout, though individual mispronunciations occasionally cost the listener a moment.
At band 6
At band 5 the listener has to work — word stress lands unpredictably and some stretches need rereading in the mind to parse.
What to practise
Slow down and put the stress in the right place on long words. Speed is not fluency, and at this band it is actively costing you intelligibility.
What band 6 actually asks of you
Being understood, and keeping going. That is very nearly the whole descriptor. Band 6 tolerates a great deal of error — mispronunciations that cost the listener a moment, complex sentences that come out wrong, hesitation while you look for a word. None of that stops you reaching it.
What does stop you is silence, and answers that end after four words. A candidate who speaks for the full time with frequent mistakes will usually outscore one who produces three short, perfect sentences and then stops. Volume of speech is the single biggest lever at this level, and it is the one most candidates are trying hardest not to pull.
The three things worth practising first
Never answer in one clause
Every Part 1 question gets at least two sentences: the answer, then a reason or an example. This one habit is worth more than any amount of vocabulary study at band 5.
Learn to talk around a word you don't know
Paraphrase is explicitly rewarded in the descriptors. 'The thing you use to open bottles' scores; a four-second pause while you hunt for 'corkscrew' does not.
Add one relative clause per answer
'I studied engineering, which I chose because my father is an engineer.' It is a single structure, it is easy to drill, and complex sentences are a named requirement.
Oliver runs the full test and scores each criterion separately, which matters at this level: a candidate at 5.5 overall is often already at 6 on two criteria and being held down by one. Knowing which one is the whole battle.
