What this is not
Readback English is independent study material: it is not an ICAO language proficiency test and is not equivalent to one, it is not approved by or affiliated with ICAO, any civil aviation authority or any test provider, and completing it confers no rating and no level.

Readback English sells recorded practice material: pilot and controller exchanges, plain-English situation prompts, comprehension questions and model answers, spoken by a bank of accented synthetic voices. That is the whole of what it is.
It is not a language proficiency test and it is not equivalent to one. It is not approved by, endorsed by or affiliated with ICAO, any civil aviation authority, any airline or any test provider, and none of it is produced under licence from any of them. Only a rater or examiner designated by your national civil aviation authority can assess your language proficiency and record a level against your licence. Nothing here is such an assessment, and no score, count or streak in this product predicts one.
ICAO requires no re-evaluation at Level 6; your national authority may still require one. Requirements differ between States and they change. Check what applies to you with your authority or your employer, not with us.
This is language study material, not operational guidance. Do not use anything in it as a source of procedure, phraseology, clearance or performance data in real operations. The exchanges are written to sound like the real thing and are reviewed for plausibility; they are not a reference and they are not current.
We describe the material — how many lessons, how many minutes of audio, how many accents — and never an outcome. Anyone who promises you a particular level in exchange for money is selling something we are not.
