NAATI CCL vocabulary by topic: the terms that cost marks

Updated 7 September 2026 · facts checked against NAATI and Home Affairs pages on that date

Quick answer: CCL vocabulary is the language of Australian services, across the topic areas NAATI lists. It matters because marking is by deduction from 90 marks and each error costs an amount that depends on how much it damages the communication, so a dropped service name or a changed figure is expensive. Two dialogues, two different topics, about 300 words each, in segments of 35 words or less.

The words that stop candidates are rarely difficult English. They are ordinary Australian institution names that have no clean equivalent anywhere else. Below is a topic-by-topic map of them, each linked to a plain-English explanation, plus how to turn a list into something you can produce in five seconds. Test yourself on a full dialogue on the free daily practice test.

Why a single term costs so much

NAATI assesses CCL tests using a mark deduction method: each test begins with 90 marks, and marks are taken off when a candidate makes errors, with each error costing a different number of marks depending on how much it impacts on the overall communication.

Read that against the accuracy criterion, which is about how correct the information is and not removing or adding any information. A term is usually not decoration. In a health dialogue the term is the difference between a bill the patient pays and one they do not. In a housing dialogue it is the money they get back or lose. When the term goes, the point of the segment goes with it, which is why vocabulary gaps show up as accuracy deductions rather than as a small stylistic penalty.

The second cost is delivery. Quality of delivery is assessed on there being no excessive pauses, hesitations or self-corrections, and you must begin interpreting within five seconds of the chime. Hunting for a word burns that budget. A term you half-know is nearly as expensive as one you do not know.

The topic areas NAATI lists

Each dialogue is about a different topic reflecting real-life situations in Australian society. NAATI's list is: business, consumer affairs, employment, health, immigration and settlement, legal, community, education, financial, housing, insurance and social services. Two of these come up in your test, and you do not get to choose. Domains and topics covers what a conversation in each looks like.

Health terms

The largest source of untranslatable terms. A conversation might involve Medicare and a Medicare card, whether a clinic will bulk bill, the gap fee or out-of-pocket amount, a GP referral or specialist referral, a referral letter, the emergency department of a public hospital and how triage works, medicines under the PBS, a mental health care plan, a medical certificate, or an interpreter service such as TIS National.

Social services, community and aged care

Payment and agency names are precise, and near-enough is wrong. Expect Centrelink and Services Australia, myGov, payments such as JobSeeker, Family Tax Benefit, Carer Payment, Carer Allowance, Age Pension and Rent Assistance, the income test and assets test behind them, mutual obligation requirements, a concession card or healthcare card, and disability and aged care terms such as the NDIS, My Aged Care, an ACAT or aged care assessment, a home care package, respite and a waiting list.

Employment and housing

Workplace dialogues run on paperwork. Common items are a payslip, penalty rates and casual loading, superannuation or super, a tax file number or TFN, a probation period, long service leave, an enterprise agreement, Fair Work and the Fair Work Commission, unfair dismissal, WorkCover and workers compensation with light duties on return, and pre-employment checks such as a police check or working with children check.

Renting and owning have their own set: the bond and the lease agreement, council rates, public housing, and what happens in financial hardship when a tenant or owner asks for a hardship arrangement. Payment methods such as direct debit and BPAY turn up constantly in the same conversations.

Legal, insurance and consumer affairs

Court and police vocabulary is where register matters as much as accuracy, because you must match the formality of the speaker. Terms include the local court and the magistrate, a duty lawyer and Legal Aid, a statutory declaration witnessed by a Justice of the Peace, an AVO or apprehended violence order, a good behaviour bond, an infringement notice or on-the-spot fine, demerit points, a caution, a police report with its event number, and the Family Court or Federal Circuit.

Insurance dialogues hinge on a handful of exact words: comprehensive insurance versus third party, the excess, a waiting period, private health cover and extras cover, and ambulance cover. Consumer conversations bring in the Australian Consumer Law, the ACCC, Fair Trading, an ombudsman, a cooling-off period, membership costs and buy-now-pay-later arrangements such as Afterpay.

Education, immigration and financial

School and training systems rarely map across countries. Watch for public school, kindergarten and Prep, Year 12 and the HSC, NAPLAN, TAFE and VET, a scholarship, and the online portal a parent is being asked to log into.

Settlement dialogues use Home Affairs, visa vocabulary such as a partner visa, a bridging visa, a visa condition and permanent resident status, the citizenship test, a skills assessment, and NAATI itself. Financial dialogues reuse many of the housing and employment terms above, plus a reference number for almost every transaction.

Numbers, names and the rules that govern them

Two categories sit alongside vocabulary and are marked just as hard.

Numbers. Several language policies penalise English numerals. For Hindi, Gujarati, Marathi, Malayalam, Punjabi and Odia, using English numerals is penalised, and a figure given in millions in English must be converted to lakhs or crores in the LOTE and the reverse. Marathi also names sequential counting, time and fractions. For Dzongkha, English numerals are penalised and large numbers must be given in Dzongkha equivalents. Rents, fees, dates and dosages are all numbers.

Names of authorities. For Russian, when interpreting names of authorities for which there is a formal Russian translation, candidates should use it. For Ukrainian, where there is no formal Ukrainian translation, candidates should use the English name and its transliteration or transcription. As a general habit, use the rendering your community actually uses and do not invent one on the spot.

Where an English word is regularly and commonly used by speakers of your language, Policy B says you will not be penalised for using it, even if a LOTE word exists. That is the escape hatch for service names, and it is worth knowing exactly how far it stretches in your language: see English words in your LOTE.

Building a list you can actually use

Recognition is not production. You need the word out of your mouth within five seconds of a chime, in a sentence, with the right register.

NAATI's own preparation advice is a good method: pick up literature or brochures in both languages, which might be available from a government department or online, view them critically and learn as much terminology as possible, and read magazines and newspapers in both languages to do the same. Add its speaking drills: have someone read you short passages of about 20 to 40 words and reproduce them as accurately as you can in the other language without taking notes, and record yourself so you can listen back and judge how well you conveyed the meaning.

A workable routine is to take one topic a week, collect its terms with a source sentence for each, drill them aloud in both directions, then sit a full dialogue under test conditions and mark which terms actually failed. That last step is the one that changes your score.

Our free daily practice dialogue is built for that loop: 2,241 dialogues across 50 test languages, written to the CCL specification with two speakers, segments of 35 words or fewer and around 300 words each, marked segment by segment so you can see what was retained, omitted or distorted. The score is our model's estimate, not a NAATI result. Check your language on the languages page, and if you are still building a routine, start with preparation and study plan.

Frequently asked questions

What vocabulary do I need for the NAATI CCL test?

The vocabulary of everyday Australian services, across the topics NAATI lists: business, consumer affairs, employment, health, immigration and settlement, legal, community, education, financial, housing, insurance and social services. The dialogues reflect real-life situations in Australian society, so the terms are the ones people meet at a clinic, a rental inspection or a Centrelink appointment.

Why does one missed word cost so many marks?

NAATI marks by deduction from 90, and each error costs a different number of marks depending on how much it impacts on the overall communication. A term that carries the point of the segment, such as a payment name or a legal condition, takes the meaning with it when it is dropped or changed.

What do I do with a term that has no equivalent in my language?

Under Policy B, NAATI accepts English words in the LOTE where they are regularly and commonly used by LOTE speakers, so a service name that your community says in English can usually stay in English. Check your language's own entry in the NAATI language policy, because several languages restrict this more tightly.

Am I allowed to explain a term in my own words during the test?

Be careful. Accuracy is assessed on how correct the information is and on not removing or adding any information, so an added explanation that nobody said is an insertion. Convey what the speaker said, at the same level of formality, rather than teaching the listener what a scheme is.

Should I memorise long word lists?

Lists help, but only if you can produce the word within five seconds under pressure. NAATI's own advice is to pick up brochures in both languages from a government department or online, read them critically, learn as much terminology as possible, and read magazines and newspapers in both languages.

How many topics can come up in one test?

Two. The test has two dialogues and each dialogue is about a different topic, drawn from the areas NAATI lists. You do not know in advance which two, so prepare across the whole list rather than betting on a few.

Do numbers count as vocabulary?

For several languages they are a marking issue in their own right. For Hindi, Gujarati, Marathi, Malayalam, Punjabi and Odia, use of English numerals is penalised, and a figure given in millions in English must be converted to lakhs or crores and vice versa. Rents, fees and dates are full of numbers.
