Abstract: There exist different competency-based training models which focus on “the fact of being competent” or/and “the process of becoming competent”. So, the models can be divided into three types, such as process-oriented, outcome-oriented and comprehensive-oriented. But different models own the same features, for example, the first one is “the standard of competent” which means the same foundation; the second one is “the process of becoming competent”; and the last one is the goal, i.e. “the fact of being competent”. In the future, the study on instructional design, status of trainees, roles’ balance and technological factors should be layed emphasis on.

Key words: competency-based training, competency, training model, process-oriented, outcome-oriented
