ICAO Language Proficiency
Rating Scale

How is your grade determined?

Your skills are assessed according to the ICAO language proficiency skills defined in the ICAO Rating Scale. The final grade corresponds to your language proficiency (Passed (Level 4,5, 6), Failed (Level 1, 2, 3)). The final rating is not the average or aggregate of the ratings in each of the six ICAO language proficiency skills, but it is the lowest of these six ratings. Your Language Test is assessed by a certified and authorized Language Assessor, licensed under the Danish CAA.
