ICAO Level 6 Rewards Adapting to a Weaker Speaker

Almost every English exam rewards the same thing. Wider vocabulary, more complex sentences, more of your own range on display.

Aviation English at its top level does the opposite. ICAO Level 6, as the recognised test describes it, assesses your ability to adapt to somebody who speaks worse than you do.

SpeakShark is free to practise the kind of talking that is about the other person, three AI conversation sessions a day with no card.

Key takeaways

• ICAO Level 6 is assessed by a separate test in the ELPAC suite.
• It rewards adapting to a less proficient speaker, not displaying range.
• It also assesses dealing with misunderstandings and resolving ambiguity.
• The ICAO recognised list held two tests, both from Eurocontrol.
• 91 per cent of ELPAC candidates pass at the first attempt.

The inversion

Here is the passage, and it is unusually blunt for a test provider describing its own product.

Traditional language tests, ELPAC writes, assess the ability of the test taker to show off their language ability as best they can, and the highest scores are usually awarded to test takers who can impress with the range of their vocabulary or the complexity of their grammar.

The ELPAC level 6 test, it continues, has been designed to assess the ability of pilots and air traffic controllers to communicate effectively using radiotelephony communications. Effective communication is achieved by demonstrating the ability to adapt to a less proficient speaker or a speaker from a different cultural background. It also means dealing with misunderstandings and identifying and resolving ambiguity.

Read that against how every academic English exam behaves and the inversion is complete. Elsewhere, a candidate who simplifies is a candidate who has less to show. Here, a candidate who simplifies for the person on the other end of the radio is demonstrating the thing being measured.

Levels 4 and 5 are a different test

The ELPAC suite comprises three tests: ELPAC ATC, ELPAC pilots, and ELPAC level 6.

ELPAC ATC assesses the full range of communicative tasks at ICAO levels 4 and 5 that an air traffic controller may face in the operations room or the control tower. ELPAC describes controllers relying on ICAO standardised phraseology in everyday situations, and having to shift between standardised phraseology and plain English in unexpected situations in order to support flight crews.

ELPAC pilots assesses the ability of pilots to communicate effectively with air traffic control at ICAO levels 4 and 5, requiring them to make requests, report unexpected situations, negotiate, and resolve potential misunderstandings.

So the suite splits at the top. Levels 4 and 5 are covered by audience-specific tests, and level 6 is its own instrument with its own design philosophy.

That structure is itself informative. If level 6 were simply level 5 with a higher bar, a single test with a wider scale would do. Building a separate test for it says the thing being measured changes.

The recognised list has two entries

ICAO publishes the tests it has assessed through its Aviation English Language Test Service, in two tiers.

Conforms: tests that meet all of the ICAO Language Proficiency Requirements and follow good language testing practices.

Partially Conforms: tests that generally meet established criteria but need some improvement. Providers get one year to make the changes, with additional time possible if they show progress.

At the time of reading, that list contained two tests, both from Eurocontrol: ELPAC ATC and ELPAC Pilot.

Two entries is a short list for a worldwide mandatory requirement, and it needs an immediate caveat that any honest write-up has to carry. ICAO recognition is a voluntary service for test providers, and it is national aviation authorities that approve tests for licensing. Two recognised tests does not mean two usable tests. Many national authorities approve tests that have never been through the ICAO process.

There is also a discrepancy worth reporting rather than resolving. The ICAO list shows both ELPAC ATC and ELPAC Pilot. ELPAC's own site says the ATC test is fully recognised by ICAO for compliance with ICAO Doc 9835, and that the pilot test is being reviewed, with a positive decision expected. Both statements are published. We are not picking one.

What the provider publishes about usage

Eurocontrol publishes four figures on the ELPAC site.

The pass rate is the one worth pausing on. 91 per cent at the first attempt is high for a high stakes professional exam, and it is a provider-published figure rather than an independent audit, so treat it as what ELPAC reports rather than as a verified statistic.

It also fits the design. A test built around whether you can be understood and can understand, rather than around how much language you can produce, is a test most working professionals should pass.

Why an aviation exam would be built this way

The reasoning is not stated on the page, so this is our reading rather than ELPAC's.

Radiotelephony is a two-way channel between people who very often do not share a first language, under time pressure, where the cost of a misunderstanding is not a lower grade. The controller and the pilot may be at different proficiency levels on the same transmission.

In that setting, the most linguistically impressive speaker is not the safest one. The safest one is whoever notices that the other person has not understood and does something about it.

That is the same skill Cambridge scores as Interactive Communication, and it is the one criterion that cannot be practised alone, which we set out in Interactive Communication across levels. It is also what Michigan's C2 exam is reaching for when it puts two or three candidates in the room together rather than one, covered in ECCE against ECPE.

Aviation just says it out loud.

What this changes about practising

• Practise being understood, not being impressive. The two are different targets.
• Practise repair. Noticing a misunderstanding and fixing it is named in the description.
• Practise with speakers unlike you, since adapting across proficiency and culture is the stated skill.
• Do not treat level 6 as level 5 with harder words. It is a separate test.
• Check your national authority, not only the ICAO list, for which tests count where you fly.

Adapting to another speaker only develops against another speaker, which is why role play scenarios and a daily speaking partner do more for it than vocabulary work. Testing your speaking level free gives you a starting point and CEFR levels for speaking explains the general scale, though ICAO uses its own.

For other professions where speaking is the decisive gate, CELBAN speaking runs 35 minutes of role play for nurses in Canada, the GMC requirement for doctors counts only your most recent sitting, and Irish nursing English lets you choose which skill drops. Cambridge speaking criteria by level shows real scored candidates, and Linguaskill and Aptis are the closest general comparisons we have written.

What we could not verify

We did not obtain the ICAO level descriptors or the retest intervals. The ICAO Documents and Manuals page returns a 404 in a browser as well as to a command line fetch, so that route is dead rather than blocked. ICAO Doc 9835 or a national aviation authority is the place to get them.

We did not read Doc 9835 itself. It is named as the reference standard on the ELPAC site and we have not opened it.

The usage figures are provider-published. 66 organisations, 22,000 candidates, 300 examiners and 91 per cent are what ELPAC states about itself.

We did not check national approval anywhere. Which tests a given aviation authority accepts is set nationally, and we have checked none of them.

The recognition discrepancy is reported, not resolved. The ICAO list and the ELPAC site say different things about the pilot test.

Our explanation of why the exam is built this way is our own inference, clearly marked as such above. ELPAC states the design; it does not state the reasoning.

How we researched this guide

We reached the ICAO material through a browser after guessed paths failed. Both a command line fetch and a page summariser returned 404 on ICAO paths, including one that ICAO itself links from its own navigation, so we navigated from the programme home page and harvested the links instead of guessing at them.

That produced the recognised tests list, which is where the two-entry finding came from, and a link to the provider whose tests are on it. Reading the provider site is where the level 6 description sits, and it is not on any ICAO page we saw.

We then checked the recognition claim in both directions rather than reporting one side, which is how the discrepancy surfaced. A single source would have given us a clean sentence and a wrong one.

We have left the ICAO level scale out entirely rather than reconstructing it from secondary sources, because a scale is exactly the kind of thing that gets quoted wrong and then repeated.

Practise speaking, from SpeakShark

SpeakShark is an AI English speaking practice app, and this is the most direct argument for practising conversation rather than vocabulary that we have found in any exam document.

If the skill being measured is adapting to the person in front of you, it can only be built against something that responds. You talk, the AI answers what you actually said, and you get speaking feedback while the conversation is still running. The free tier gives basic feedback; the detailed pronunciation and grammar breakdown is on Premium.

Being straight about the limits: a free session runs five minutes with four turns, and we are a general speaking tool. We do not train radiotelephony phraseology, which is a specialist skill with specialist material, and nothing here prepares you for the operational content of an aviation English test.

Start free with three sessions a day and no card. Paid sessions run ten minutes with unlimited turns. Limits are on the pricing page, and how it works walks through a session. Sign up here if you want to practise being understood rather than being impressive.

We are a speaking improvement tool. We are not an exam preparation provider, and we are not affiliated with Cambridge English, the IELTS partners, Pearson or any exam board. For test format, booking and official practice material, go to the exam body directly. Use SpeakShark to make your spoken English stronger, and use official material to learn the test.
