This study is an exploratory study, which was conducted in relation to the study of the proficiency and performance of Iranian Air Traffic Controllers: attitude, work experience, and specific Aviation English courses. Few studies have been conducted in this field. The Aviation English Courses in Iran are very similar to Content-Based Language Training (CBLT) courses. To this end, the participants were 278 Iranian ATCOs who were selected from 1000 Iranian ATCOs based on Cochran formula. The instrument was designed by the European organization for the safety of air navigation. For data to be analyzed in this study, software SPSS 24.0, AMOS 23.0, structural equation model (SEM), path analysis model, and confirmatory factor analysis (CFA) have been used. According to the main findings of this research based on its research hypotheses, firstly, the Iranian ATCOs’ performance had a significant positive effect on proficiency. But in the effect of performance on proficiency, work experience did not have a positive moderating role and passing CBLT courses had a positive moderating role. Secondly, Iranian ATCOs’ work experience and passing CBLT courses in the effect of attitude on proficiency had not a good mediator. The results of this research can be used to improve the aviation English training in Iran Airports and Air Navigation Company.

这项研究是一项探索性研究，与伊朗空中交通管制员的熟练程度和表现研究有关：态度，工作经验和特定的航空英语课程。在这一领域很少进行研究。伊朗的航空英语课程与基于内容的语言培训（CBLT）课程非常相似。为此，参与者是278名伊朗ATCO，他们是根据Cochran公式从1000个伊朗ATCO中选出的。该仪器是由欧洲组织设计的，旨在确保空中航行的安全。对于本研究中要分析的数据，已使用软件SPSS 24.0，AMOS 23.0，结构方程模型（SEM），路径分析模型和验证性因子分析（CFA）。根据该研究假设的主要发现，首先，伊朗ATCO的表现对熟练程度产生了显着的积极影响。但是，在绩效对熟练程度的影响中，工作经验没有起到积极的调节作用，而通过CBLT课程则起到了积极的调节作用。其次，伊朗ATCO的工作经验和通过CBLT课程对态度对熟练程度的影响都不是很好的调解人。这项研究的结果可用于改善伊朗机场和空中航行公司的航空英语培训。伊朗ATCO的工作经验以及通过CBLT课程对态度对熟练程度的影响都不是很好的调解人。这项研究的结果可用于改善伊朗机场和空中航行公司的航空英语培训。伊朗ATCO的工作经验以及通过CBLT课程对态度对熟练程度的影响都不是很好的调解人。这项研究的结果可用于改善伊朗机场和空中航行公司的航空英语培训。
