This is the official website for ICAO's initiative on Language Proficiency Requirements (LPR). Here you will find a lot of information related to the programme.
Kindly note that the 38th Session of the ICAO Assembly (October 2013) adopted Resolution A38/8 – Proficiency in the English language used for radiotelephony communications. The text of this resolution can be found here.
Further to the adoption of this resolution, please note that the Interactive map providing information based on States` implementation plans for language proficiency requirements has been removed until a new map based on the protocol questions of the Universal Safety Oversight Audit Programme Continuous Monitoring Approach has been developed. Thank you for your understanding
