Our scoring guide covers the 63/90 pass mark and the 29-per-dialogue floor — the rules of the game. This page goes underneath those rules, into how marks are actually lost inside a single 35-word segment: the three deduction families, what separates a shrug-worthy minor error from an expensive major one, and the specific habits that quietly bleed marks across a whole dialogue. Worked Punjabi–English examples throughout, and one honesty note held to all the way down: NAATI does not publish these deduction values, and neither does anyone else with a straight face.
- Errors fall into three families: distortions (meaning changed), omissions (meaning dropped), and insertions/unnatural language (meaning added or expressed unidiomatically).
- The same error type can be minor or major — what tips it over is whether a real listener would act differently because of it.
- Segments (~35 words) are marked by idea unit, not as one all-or-nothing block — so one dropped detail costs less than the whole segment.
- A separate language-quality component (fluency, grammar, vocabulary, register) decides the gap between two candidates who conveyed identical content.
- Negations, conditions, third-person reporting and long silences are specific, nameable habits that cost marks beyond the well-known 'numbers and dates' warning.
- NAATI does not publish per-error point values. Any numeric model here — including ours — is a self-marking approximation, not NAATI's rubric.
Deeper than the pass mark
Knowing you need 63 out of 90, with at least 29 on each of the 2dialogues, tells you the target. It doesn't tell you how a single segment actually gets marked — and that gap is where most self-directed preparation stalls, because people practise "for accuracy" in the abstract without knowing what an examiner is actually listening for inside 35 seconds of speech.
The three deduction families
Every content error in a CCL segment sorts into one of three families. Learning to hear your own errors this way — in practice, not just in theory — is the fastest route to fixing them.
| Family | What happens | Listener impact |
|---|---|---|
| Distortion | Meaning is changed — a number, name, date or condition rendered incorrectly. | The listener acts on wrong information. |
| Omission | Meaning is dropped entirely — a clause, detail or whole idea never makes it across. | The listener never receives that idea at all. |
| Insertion / unnatural language | Meaning is added that wasn't said, or the rendering is technically complete but expressed unidiomatically. | The listener is misled, or has to work harder to understand a message that should have been clear. |

What tips a minor error into a major one
The same error type can land as minor or major depending on one question: would a real listener, in that room, act differently because of this change? That single test does more work than any list of examples.
- 1Does it change a decision or an action?A wrong dosage, a wrong date, a dropped condition — these change what someone does next. That's the signature of a major error.
- 2Does it change a fact that matters, or a fact that doesn't?Dropping 'please' is a courtesy loss. Dropping 'not' in 'do not drive after taking this' is a safety loss. Same grammatical category (a small word), completely different weight.
- 3Could the listener still infer it correctly from context?If the rest of the segment makes the missing piece obvious or low-stakes, severity drops. If the missing piece was the only carrier of that information, severity rises.
- 4Is it isolated, or does it compound with another error nearby?Two minor errors in the same idea unit — say, a slightly wrong number AND a dropped condition on the same instruction — often compound into something closer to major, because together they leave the listener with a materially wrong picture.
How idea units are counted inside a segment
A useful way to prepare — and to self-mark practice recordings — is to break each 35-word segment into its discrete idea units before you listen for errors, rather than judging the segment as one pass/fail blob.
Broken into idea units: (1) two tablets, (2) in the morning, (3) the condition — if pain returns, (4) the time marker — after 3pm, (5) take one more, (6) the ceiling — never more than four in a day. Six units, one segment. A candidate who renders five of six but drops the ceiling has kept most of the segment intact while dropping the one unit most likely to matter if someone actually followed the instruction.
This is a practical framework for self-assessment, not a claim about NAATI's internal marking software — but breaking segments into idea units this way is exactly the skill that makes our guide to avoiding omissions actionable rather than just cautionary.
The language-quality component
Content accuracy is the majority of the mark, but it isn't all of it. A separate, real component assesses how you said it: fluency, grammar, vocabulary choice and register. This is the component that decides the gap between two candidates who both technically conveyed every idea unit — one smoothly and naturally, the other haltingly or in stiff, translated-sounding sentences.
| Language-quality factor | What it actually assesses |
|---|---|
| Fluency | Smooth, continuous delivery without excessive hesitation or false starts. |
| Grammar | Correctly formed sentences in both languages — not word-for-word transfer of source grammar. |
| Vocabulary | Natural, idiomatic word choice a real community member would use, not a stilted or overly literal one. |
| Register | A tone appropriate to the professional scenario, held consistently across the whole dialogue. |
Two candidates can carry identical content and land on different marks. The difference is never the meaning — it's how it arrived.
First person, not third
Community interpreting convention — and what CCL dialogues expect — is direct, first-person rendering. The patient says “I have a headache” and you say it in first person too, not “she says she has a headache.” Switching to third-person reporting under pressure is a common habit, especially for candidates more used to summarising than interpreting, and it's treated as more than a style slip: it inserts a layer of reported speech the original speaker never used, and it often signals other fidelity problems in the same breath (softened tone, dropped urgency, paraphrase creeping in). Our guide to direct-speech interpreting covers the habit and the fix in full.
Negations and conditions: the two most-missed idea units
Numbers, dates and names get warned about constantly — rightly. Two categories get warned about far less, and they fail candidates just as often: negations and conditions.
| Type | Example | What goes wrong |
|---|---|---|
| Negation | “Do not take this on an empty stomach.” | Under pressure, the 'not' vanishes and the instruction inverts into its opposite — a major distortion, not a minor slip. |
| Condition | “Only come back if the fever is still there after two days.” | The condition drops and an optional, contingent instruction becomes a flat command — exactly the error in the worked distortion example above. |
| Frequency | “Every other day, not every day.” | The contrastive correction gets lost and the wrong frequency survives into the rendering. |
Long silences and what they actually cost
Silence itself isn't a named deduction category the way a distortion is — but a long pause is rarely free. It damages the fluency dimension of the language-quality component directly, and in practice it's usually a leading indicator of a bigger problem: candidates who freeze for two or three seconds then often rush the rest of the segment, which is exactly when omissions and distortions cluster. Treat a long silence in your own practice recordings as a flag to investigate, not a harmless pause.
A self-marking model — clearly labelled as ours
| Error, roughly | Illustrative weight | Why (our reasoning, not NAATI's) |
|---|---|---|
| Minor omission (a softener, a filler phrase) | Very small | Low-stakes, rarely changes what a listener would do. |
| Major omission (a condition, a negation, a safety instruction) | Substantial | Changes what a listener understands or does next. |
| Minor distortion (a slightly off but harmless rewording) | Small | Meaning drifts but the practical outcome is unchanged. |
| Major distortion (wrong number, date, name or inverted meaning) | Heavy | A listener would act on incorrect information. |
| Insertion of invented content | Moderate to heavy | Misleads the listener about what was actually said. |
| Unnatural language, content intact | Small, cumulative | Costs language-quality marks, not content-accuracy ones — but adds up across a dialogue. |
Use this the way you'd use a practice rubric for any skill: consistently, so your self-scoring means the same thing from one practice session to the next — not as a substitute for the actual score calculator, which estimates your likely pass position against the real 63/90 and 29-per-dialogue thresholds.
If you're running this checklist against a real result you already have rather than a practice recording — because you sat the test and it didn't go the way you hoped — our guide to what to do after a NAATI CCL fail picks up from exactly here: how to diagnose which of these families cost you the most marks, and what that means for your next attempt.
