Inside the Assessment: What Your Four Speaking Sub-Scores Actually Mean
When you take the speaking assessment on the platform, you get back a CEFR level. B1+. B2. C1. The level is the headline number, and the one most professionals fixate on. Underneath the level, you get four sub-scores. Fluency. Lexical range. Grammatical range. Coherence.
Most professionals glance at the sub-scores and move on. That is a mistake.
The CEFR level is the floor. The sub-scores are what tell you which of the four sub-skills is dragging you to that floor, and which of them is propping you up. If you want to move from B1+ to B2 in the next six months, you are not going to do it by working on all four equally. You are going to do it by working on the one that is dragging you down.
This post is what each sub-score actually measures, what a low one looks like in a real meeting, and what to practise to move it.
Fluency: the rhythm of your English
Fluency, in our scoring, is not about how fast you speak. It is about how smoothly you can keep the rhythm of natural English conversation — appropriate pauses, recovery from a stumble, ability to keep speaking while you assemble the next sentence.
A low fluency sub-score looks like silent pauses while you think, false starts followed by visible self-correction, sentences that begin, stop, and re-begin in different shapes. The listener hears effort. The cost is conversational standing — you sound like the person the room slows down for.
A high fluency sub-score looks like you keep talking while you think, you recover from a wrong word by integrating it into the rest of the sentence, your sentences land where they were going.
The fastest way to move fluency: stop pausing silently and start thinking aloud. Phrases like "Let me think for a moment", "So what I would say is...", "There's a couple of things going on here" buy you thinking time without breaking rhythm. We covered this in detail in last week's hesitation hack post. The other lever is practice volume — fluency moves with hours of speaking, more than any other sub-score.
Lexical range: the variety of your vocabulary
Lexical range is not about knowing rare words. It is about having the right word for the situation and not repeating yourself when a more precise option is available.
A low lexical range sub-score looks like the same word appearing five times in three sentences, the wrong register for the context ("get" when the situation needed "receive", "good" when the situation needed "thorough"), and a noticeable narrowness in the way you can describe complex ideas.
A high lexical range sub-score looks like word variety that does not show off, registers that match the context, and the precision to pick the right word for the right moment. A C1 speaker does not use more words than a B2 speaker. They use the right ones.
The fastest way to move lexical range: notice the words your colleagues use that you understand but never use yourself. Write them down. Use one of them, deliberately, in your next meeting. This moves words from passive vocabulary (you recognise them) to active vocabulary (you can produce them). Most non-native professionals have a passive vocabulary that is two or three times larger than their active one. The work is to close that gap.
Grammatical range: not "correct grammar"
Grammatical range is the most-misunderstood sub-score. It is not "you made fewer grammar mistakes." It is the variety of grammatical structures you can use to express complex ideas.
A low grammatical range sub-score looks like all your sentences being simple SVO (subject-verb-object), no subordinate clauses, no relative clauses, no conditionals, no perfect tenses. The grammar is correct, but the range is narrow. You can communicate, but you cannot nuance.
A high grammatical range sub-score looks like a sentence with a subordinate clause that introduces a condition, plus a relative clause that adds context, plus a modal that signals stance. "If we had known about the regulatory review, which the legal team raised last quarter, we would have built the timeline differently." That sentence does a lot of grammatical work. It is the kind of sentence senior English speakers reach for naturally.
The fastest way to move grammatical range: pick one structure you do not currently use and force yourself to use it once a day for two weeks. Conditional sentences ("If X, then Y"). Relative clauses ("the report that we discussed"). Past perfect ("by the time we received the brief, the deadline had already passed"). The grammar is not the problem — the production is.
Coherence: how easily someone can follow your thinking
Coherence is whether the listener can follow the structure of what you are saying. It is the sub-score that decides whether the room is with you or behind you.
A low coherence sub-score looks like good individual sentences that do not connect — the listener loses the thread between sentences and has to rebuild the structure themselves. A high coherence sub-score looks like signposting ("there are three things to say about this"), discourse markers that connect sentences ("that said", "as a result", "for instance"), and a clear argumentative shape.
This is the sub-score most under-practised by non-native speakers, because it is the hardest to notice on yourself. You can hear when your fluency stumbles, when your vocabulary is repeating, when your grammar tightens. You cannot easily hear when your structure is unclear, because from the inside, your structure feels obvious.
The fastest way to move coherence: signpost your structure before you deliver it. "There are three things I want to say. First... Second... Third..." Most non-native professionals avoid this construction because it feels mechanical. It is not mechanical to the listener. It is a courtesy. It signals that you have organised your thinking and that they should organise their listening.
What to do with the four numbers
If you have taken the assessment, you have four numbers. The lowest of the four is the one you should be working on this quarter. The temptation is to work on all four — do not. Work on the one that is keeping your overall level low.
If fluency is the lowest, the issue is rhythm. Practise speaking volume, practise the hesitation phrases, and accept that fluency moves with hours, not weeks.
If lexical range is the lowest, the issue is active vocabulary. Notice and produce words your colleagues use that you have never used yourself.
If grammatical range is the lowest, the issue is structural variety. Pick one underused structure and force production for two weeks.
If coherence is the lowest, the issue is structure. Practise signposting before delivery.
The CEFR level tells you where you are. The sub-scores tell you what to work on. Most professionals never look at the four numbers carefully. The ones who do are the ones who actually move.
TL;DR
The CEFR level on a speaking assessment is the floor; the four sub-scores tell you which sub-skill is keeping you there. Fluency is the rhythm of your English (silent pauses cost you here). Lexical range is the variety of your active vocabulary (not rare words — right words). Grammatical range is the variety of structures you can produce, not the correctness of your grammar. Coherence is whether the listener can follow your structure — most non-natives under-rate this because it is the hardest sub-score to hear on yourself. Work on the lowest of the four; the temptation is to work on all four equally, which is how most professionals stay where they are.

📖 Key Vocabulary
sub-scorenoun · C1
A score for one specific component of a larger overall score. Revisited from the CEFR-level post: where the CEFR label is the headline, sub-scores are the diagnostic underneath.
“The CEFR level is the floor; the four sub-scores tell you which sub-skill is keeping you there.”
rhythmnoun · B2
The pattern of pauses, stresses, and pace in natural speech — what makes English sound smooth rather than effortful.
“Fluency is about how smoothly you can keep the rhythm of natural English conversation.”
recovery (n.)noun · C1
The act of getting back on track after a stumble — picking up the sentence after a wrong word or false start without breaking flow.
“A high fluency sub-score looks like recovery from a wrong word by integrating it into the rest of the sentence.”
false startnoun phrase · C1
A sentence that begins, breaks off, and restarts — often with visible self-correction. A hallmark of low-fluency speech.
“A low fluency sub-score looks like false starts followed by visible self-correction.”
lexical rangenoun phrase · C1
The variety of vocabulary a speaker can produce — having the right word for the situation and not repeating yourself when a more precise option is available.
“Lexical range is not about knowing rare words; it is about having the right word for the situation.”
active vocabulary vs passive vocabularynoun phrase · C1
Active vocabulary is the words you can produce in speech and writing; passive vocabulary is the words you understand when you hear or read them but never produce yourself. The gap between the two is usually large for non-native professionals.
“This moves words from passive vocabulary (you recognise them) to active vocabulary (you can produce them).”
grammatical rangenoun phrase · C1
The variety of grammatical structures a speaker can use to express complex ideas — not the absence of errors, but the breadth of patterns produced.
“Grammatical range is not 'correct grammar'; it is the variety of structures you can use.”
structural varietynoun phrase · C1
The breadth of sentence structures a speaker uses — subordinate clauses, relative clauses, conditionals, perfect tenses — beyond simple SVO patterns.
“If grammatical range is the lowest, the issue is structural variety.”
coherencenoun · C1
How easily a listener can follow the structure of what a speaker is saying — whether the connections between sentences are clear.
“Coherence is whether the listener can follow the structure of what you are saying.”
signpost (v.)verb · B2
To make the structure of what you are about to say clear before you say it — for example, 'there are three things to say about this'. Revisited from the CEFR-level post, where it appeared as a feature of structural confidence.
“Signpost your structure before you deliver it.”
discourse markernoun phrase · C1
A word or short phrase that connects one piece of discourse to another and signals the relationship between them — 'that said', 'as a result', 'for instance'.
“Discourse markers that connect sentences ('that said', 'as a result', 'for instance').”
hedge (v.)verb · C1
To soften a statement by qualifying it — adding caution, distance, or uncertainty so the claim is less absolute.
“A C1 speaker can hedge a strong claim without weakening their position.”
production (in language production)noun · C1
The act of generating language in speech or writing, as opposed to recognising or understanding it. Often the bottleneck for non-native speakers, who can understand more than they can produce.
“The grammar is not the problem — the production is.”
under-rateverb · C1
To value or judge something as less important than it really is.
“Most non-natives under-rate coherence because it is the hardest sub-score to hear on yourself.”
under-practisedadjective · C1
Not practised enough — receiving less deliberate work than it should, relative to its importance.
“Coherence is the sub-score most under-practised by non-native speakers.”
⚙️ Grammar Notes
Imperative for direct instruction in advice writing
The bare imperative form (verb with no subject) is the workhorse of direct advice writing in English. It addresses the reader without softening the recommendation through hedges like 'you might want to consider' or 'it can be helpful to'. In professional coaching prose, the imperative signals confidence — the writer knows what to do, and the reader is being told. British English uses the imperative liberally for advice; over-hedging is a hallmark of weak professional writing.
→“'Work on the lowest of the four.' / 'Notice and produce words your colleagues use that you have never used yourself.' / 'Pick one underused structure and force production for two weeks.'”
Common mistake: Softening every imperative with 'you should' or 'it would be a good idea to' dilutes the advice. 'Work on the lowest of the four' is stronger than 'You should probably work on the lowest of the four' — the second version invites the reader to dismiss the advice.
Restrictive relative clauses for definition
A restrictive relative clause (no comma, introduced by 'that' or 'who' or with the pronoun omitted) restricts the noun it modifies — it tells the reader which specific sub-score, which specific words. Restrictive clauses are essential for definition writing because they pin a general noun ('sub-score', 'words') down to the precise referent the writer means. The clause is not extra information; it is what makes the noun specific.
→“'It is the sub-score that decides whether the room is with you or behind you.' / 'words your colleagues use that you have never used yourself.'”
Common mistake: Using 'which' with a comma turns a restrictive clause into a non-restrictive one and changes the meaning. 'The sub-score, which decides whether the room is with you, is coherence' implies all sub-scores do this; 'the sub-score that decides whether the room is with you' specifies coherence alone.
Conditional advice pattern 'If X is lowest, the issue is Y'
First conditional with 'if + present simple' in the condition and 'present simple' in the result — used here as a diagnostic-to-prescription bridge. The 'if' clause names the reader's specific situation; the result clause names the underlying issue. The pattern repeats four times in parallel, which gives the section a clear structure and lets the reader find their own situation quickly. This is a high-leverage pattern for any 'what to do with this' section in professional writing.
→“'If fluency is the lowest, the issue is rhythm.' / 'If lexical range is the lowest, the issue is active vocabulary.' / 'If coherence is the lowest, the issue is structure.'”
Common mistake: Switching to 'if + would' or 'if + should' weakens the advice. 'If fluency would be the lowest' is hypothetical; the post is making a direct diagnostic claim, which requires present simple in both clauses.
