Therefore, the Finnish Defence Forces will also need professional and motivated individuals both now and in the future. The variable, interdependent, and complex environment has set totally new requirements for future＇s officers1. The Finnish cadets＇ selection process plays a crucial role, because the Finnish Defence Forces educate and train all the officers by itself. By means of the student selection will be made decisions whose influences have long temporal dimension, The officers who graduate from the Finnish National Defence University will build up the tomorrow＇s Finnish Defense Forces. In this paper, it will address the quality and functionality of the Finnish Defence University＇s student selection processes as part of competence and knowledge management from the organization＇s point of view2. Because of overall changes of society and the security environment, the Finnish officers＇ education and training system （see Figure 1） has been modified frequently during the few recent years. Both the reforms of the degree programs of Military Science and the Finnish higher education culture＇s modifications have been tried to notice during the analysis. The paper is based on the author＇s doctoral thesis that is compiling at the moment.展开更多
