Does RELTA provide results according to the ICAO levels?
Answer
Yes. RELTA, has been trialled extensively with pilots and air traffic controllers whose first language is not English. In summary, the trials found the RELTA test to be:
an extremely reliable test
a valid and effective measure of language proficiency
an appropriate and valid test for pilots and air traffic controllers (measuring language areas associated with communication in both radiotelephony and face to face contexts)
an appropriate test instrument for assessing pilots/air traffic controllers in relation to the 6-band ICAO rating scale
