ICAO level 4 structure/grammar checklist

Below are the structures that ICAO considers to be ‘basic’ structures. Candidates who want to achieve level 4 should have a good command of these structures and should be able to use them in whatever situation they are needed. Simple errors with these structures are expected but overall communication errors should be infrequent. The examiner should almost always be able to understand your ideas. 

Candidates should not use only these structures but should try to use more complex structures when they can, although level 4 candidates are not expected to use complex structures well.

If you’re not sure about any of these structures search for the structure on this website to learn more about it and review it.
