This research aims to explore the training effectiveness of air cram schools. Among local, there is no precedent on related aviation cram schools yet. Therefore, this research has focused on discussing the training effectiveness of air cram school in terms of pre-employment training, training effectiveness and its impact on air industry. We hereby derive research object samples-2 air cram school suppliers, 4 airlines, 2 professors from department of aviation service, 2 cabin crews with or with no training course, respectively, with 12 samples derived for in-depth interviews. Through consolidation, coding, summary and analysis of interview data, it is found that those who have participated in the course could only find out whether the training course work after having an interview, however, they could only have a clear plan on their career paths after having the training course. Those who did not take the course would rather search for related recruitment information via the internet due to the confidence of better qualification as well as expensive course expense, which however, will lead to a limitation of future career path as they don't really know about themselves. Air cram schools report a different thinking from airlines suppliers, including teaching quality and contents of course training, where they disagree with each other in terms whether air cram schools save recruitment and training cost. Although aviation service belongs to pre-training institutions, the interviewees report the same viewpoints as airlines suppliers
