Why crew get the rating they did not expect
Good English and ICAO English are not the same thing.
Plenty of confident, experienced aircrew walk out of a language assessment with a rating they did not expect. Almost always for the same four reasons.

Your rating is your weakest descriptor
Six areas are scored separately and the lowest one becomes your final rating. A fluent speaker can be held at Level 4 by pronunciation alone. We find the descriptor that is costing you the level and work on it deliberately, instead of just chatting.
Phraseology runs out exactly when you need it
Standard phraseology covers the routine. Assessments, like real emergencies, are built from everything else: a passenger taken ill, a bird strike, a diversion to an unfamiliar field. Plain English is what is actually being measured.
Comprehension under load
Understanding a fast native speaker, an unfamiliar accent and a busy frequency is a trainable skill. We practise with real recordings and degraded audio until unexpected turns stop being a surprise.
Interaction, not monologue
Assessors listen for how you check, clarify, paraphrase and confirm when a message goes astray. That is a set of phrases and habits you can rehearse - most candidates never do.
The ICAO rating scale
Where you are now, and where you need to be
The ICAO rating scale runs from 1 to 6. Level 4 is the operational minimum for international flight and for controllers handling international traffic. Re-assessment intervals are set by your own authority; the intervals below are the ICAO recommendation.
The minimum
Level 4 Operational
You can handle work-related topics and unexpected turns with reasonable accuracy. Errors sometimes interfere, and a strong accent or a busy frequency can still cause a breakdown.
Re-assessment recommended every 3 years
The comfortable place to be
Level 5 Extended
You handle the unexpected with ease, your vocabulary stretches to unfamiliar situations, and errors rarely interfere with meaning. Most airlines see Level 5 as real operational safety margin.
Re-assessment recommended every 6 years
The finish line
Level 6 Expert
Consistently accurate, flexible and easy to understand, even with an unfamiliar accent. Idiomatic and nuanced language is used appropriately.
Usually no further testing, subject to your authority
The six descriptors we train
01
Pronunciation
Accent is fine. Interference is not. We target the specific sounds, stress patterns and rhythms that make your transmissions hard to read.
02
Structure
The grammar that carries meaning under pressure: tenses for reporting, conditionals for intentions, question forms for clarification.
03
Vocabulary
Technical range plus the paraphrase skills that rescue you when the exact word will not come.
04
Fluency
Natural pace, useful fillers, and recovery from a false start without losing the message.
05
Comprehension
Listening work on real ATC audio, varied accents, degraded quality and non-routine content.
06
Interactions
Immediate, appropriate and informative responses - reading back, checking, confirming and resolving misunderstandings.
Training
Courses
Every course starts from a diagnostic, not from page one of a textbook. Length is a guide - some people need six weeks, some need six months.

Aviation English instructor - TEFL certified - London
About your teacher
Ten years, four countries, one obsession: English you can actually use
I am a British native speaker and certified ESL instructor based in London. Since 2014 I have taught English professionally in the United Kingdom, Spain, Italy and Russia to aviation professionals, legal professionals and corporate teams at KPMG, Aggreko, Estrella Galicia, Gazprom and LukOil.
That work has always had the same shape: a professional with real expertise, a high-stakes situation in English, and a gap between the two. Aviation is that problem in its purest form, because the consequences of a misunderstanding can have serious safety implications.
So my lessons are not general conversation with a few aviation words dropped in. They are built on the ICAO rating scale, on real radiotelephony, on non-routine scenarios, and on the specific descriptor that is costing you your level. I keep a large archive of teaching material - books, audio and video - and I make the plan fit you, not the other way round.

- 120-hour TEFL certificate (TEFL.org.uk, 2016, renewed 2025)
- BA (Hons) History, Lancaster University
- Certificate in Quantitative Techniques and Statistics, Birkbeck, University of London (Distinction)

Questions people actually ask
Can you guarantee I will get Level 4?
No, and you should be careful with anyone who does. I do not put you forward for a test until a full mock assessment says you are ready, and I will tell you honestly if you are not there yet.
How long does it take to move from Level 4 to Level 5?
For most people, three to five months of two lessons a week plus regular listening practice. It depends far more on the weakest descriptor than on your overall English.
Which tests do you prepare people for?
The common ICAO-compliant formats: TEA, ELPAC, RELTA, EALTS and authority-run interviews. Tell me which one your authority accepts and we will train in that format.
What happens in a lesson?
Roughly: a listening warm-up on real ATC audio, targeted work on your weakest descriptor, a non-routine scenario in role play, then feedback and homework. Lessons are recorded if you want them to be.
Which platform, and which time zones?
Lessons run on Zoom. I am in London (UTC or UTC+1) and keep early morning, evening and weekend slots for crew on rotation.
Do you teach anything other than aviation English?
Yes. IELTS across all versions, Cambridge exams, business and legal English, interview and CV coaching, and GCSE and A-Level English Literature and History.
How does a written speaking report work?
You pay, I send the exercise, you record your answers on your phone in one take and send the video back. Within five working days you get a written report with scores against all six descriptors, an estimated rating and the specific things to fix. There is nothing to book and no time zone to work around.
Why do I only get the exercises after I pay?
Because a rehearsed answer tells me nothing about how you will perform on the day. The prompts used for assessment are held back and never published. The free practice exercises are a separate set, and you are welcome to work through those beforehand.
Can you rate Interactions from a recording?
Not from a single monologue, and I will not pretend otherwise. The full report includes a transmission with something in it that does not add up, so readback correction and asking for clarification become visible. If you want Interactions marked properly, take the two round option, where the follow-up questions are written from what you actually said.
What if I read my answers from a script?
The report will say so and you will not get an estimated rating. Recordings must be one take with the camera on and your face visible, started within a minute of opening the prompt. This is not about trust. A scripted answer simply cannot be marked for Fluency or Interactions.
How fast is the turnaround, and can I get it sooner?
Five working days as standard, and most come back sooner. If your test is close, priority turnaround puts you at the front of the queue for a report inside 48 hours, for £19 on top. Tell me your test date before you pay if it is inside a week, so I can say honestly whether I can help.
What if the recording is unusable, or you miss the deadline?
Full refund in both cases, no argument. There is no satisfaction guarantee on a report that has already been written, because an honest low rating is still the thing you paid for.
How do I pay?
Bank transfer or an invoice for company-funded training. Written speaking reports are paid up front, before the exercise is sent. Packages are paid up front; single lessons before the lesson. Cancel or move a lesson with 24 hours notice at no charge.
What is the ICAO English language proficiency test?
It is the licence check on your radiotelephony English. It does not measure general English: it rates six skills - pronunciation, structure, vocabulary, fluency, comprehension and interactions - against the ICAO rating scale, and your overall level is the lowest of the six. Pilots and controllers working international operations need Level 4 as a minimum.
What is the difference between Level 4, 5 and 6?
Level 4 is operational: you cope with routine work and can usually clear up a misunderstanding. Level 5 is extended: unexpected turns in a conversation cost you far less effort. Level 6 is expert, near enough native command. Level 4 and 5 have to be revalidated, typically every three and six years, while Level 6 is normally granted for good. Your authority sets the exact intervals, so check what applies to your licence.
How long does the test take?
Most formats run for roughly twenty to forty minutes. Expect an interview about your operational background, listening tasks, description of a picture or situation, and a non-routine scenario where you have to talk your way through a problem without standard phraseology. Some formats are run with an examiner in person or online; others include computer-based listening sections.
Can a non-native speaker really reach Level 6?
Yes. Level 6 is not a test of accent and you are not being asked to sound British or American. It rewards range, precision and the ability to keep going when a situation stops being routine. It takes longer than Level 4 or 5 and it is not the right target for everyone, but it is reachable, and I will tell you honestly whether it is realistic for you.
How is this different from a general English course?
A general course builds broad English. This builds the specific thing you are rated on: plain English that works alongside standard phraseology when something goes wrong. The material is real ATC audio, incident reports and role plays from the flight deck and the tower, not textbook dialogues about holidays and hobbies.
How long should I prepare?
It depends on where you are starting and how often you can work. As a rough guide, a solid Level 3 aiming at Level 4 usually needs a couple of months; Level 4 to Level 5 more like three to five; Level 6 longer again. A mock assessment in the first week or two will give you a far better estimate than any average.
What happens if I do not pass?
Below Level 4 you cannot exercise your radiotelephony privileges internationally until you retake and pass, so the licence is effectively on hold. There is no limit on retakes, but sitting the test again without changing anything rarely helps. We would go through the examiner feedback, work out which of the six descriptors pulled the score down, and target that.
