The Occupational Knowledge Test (OKT) 101-B was administered to 784 air traffic control trainees who entered the FAA Academy's 16-week training course in 1976. All trainees completed the nonradar laboratory portion of the training and, in addition, completed a preemployment questionnaire. Based on responses to the questionnaire, the trainees were assigned to one of three experience groups, corresponding to groups given credit for experience using Civil Service Commission (CSC) selection procedures. It was found that the OKT was highly correlated with experience (r = 0.64) and, in addition, had a higher correlation with successful completion of the nonradar lab than did experience (r = 0.25 vs. 0.12). It was determined that use of an OKT score of 75 or above to assign extra credit would result in a failure rate of 3.1% for those receiving credit, while use of the current experience scale would result in a failure rate of 7.6% for those receiving extra credit on the CSC selection battery. The results held up for a cross-validation sample of 432 trainees who entered the Academy during 1977. Based on the results, it is recommended that an OKT score of 75 or above be used to assign extra credit for experience in the selection of air traffic controllers.
职业知识测试（OKT）101 - B对1976年进入联邦航空管理局学院参加为期16周培训课程的784名空中交通管制学员进行了测试。所有学员都完成了培训的非雷达实验室部分，此外，还完成了一份入职前问卷。根据问卷回答，学员们被分配到三个经验组之一，这与根据公务员委员会（CSC）选拔程序获得经验学分的组相对应。研究发现，OKT与经验高度相关（r = 0.64），此外，与非雷达实验室的成功完成情况相比，OKT与经验的相关性更高（r = 0.25对0.12）。经确定，使用75分及以上的OKT分数来给予额外学分，对于获得学分的人来说，失败率为3.1%，而使用当前的经验量表，对于在CSC选拔组中获得额外学分的人来说，失败率为7.6%。对于1977年进入学院的432名学员的交叉验证样本，结果依然成立。基于这些结果，建议在选拔空中交通管制员时，使用75分及以上的OKT分数来给予经验额外学分。
