English Proficiency
The ICAO Language Proficiency Requirements (LPRs) were established under ICAO Assembly Resolution A32-16 and formalized in Annex 1 (Amendment 164). Since March 5, 2008, all pilots and air traffic controllers operating on international routes must demonstrate at least Operational Level 4 proficiency in English. This guide covers the six proficiency levels, the holistic descriptors, the rating scale, and how to prepare for your test.
