One year has already passed since the International Civil Aviation Organization’s (ICAO) language proficiency requirements (LPRs) test was implemented in Korea. The purpose of this study was to investigate the military air traffic controllers’ (ATCs) perceptions and their needs on English Proficiency Test for Aviation (EPTA) test. To do that, the results were compared with civilian ATCs’ perceptions which were analyzed by Shin and Kim (2005). A total of 60 active duty Air Force ATCs participated in the survey process. The questionnaire was composed of 27 items including 23 multiple choice and 4 open-ended questions. All results were discussed in the following categories: general perception of the EPTA, specific needs for military ATCs and test preparations. The results showed that gaps still exist among ICAO LPRs, the current EPTA test, and military ATCs’ specific needs. It was suggested that, to make more customized aviation English tests in the Korean ESP field as well as to meet the ICAO LPRs, it is necessary for all relevant governmental organizations, language test groups, and test experts to continuously pay attention to test-takers’ practical and specific needs.
