Main criteria for professional include the following:
Reasonable work moral and motivation. Having interest and desire to do a job well as well as holding positive attitude towards the profession are important elements in attaining a high level of professionalism.
The unique and indispensable characteristic of a professional is the ability to exercise sound and reasonable judgment about important matters in conditions of uncertainty. This ability, in turn, depends upon three other factors that are necessary conditions for someone to exercise this sort of judgment: the professional must possess specialized knowledge, must make critical commitments, and must be permitted autonomy in decision making.
Professionalism is important in the military for two significant reasons. First, the military leader is a public servant responsible for the defense of the nation. Second, the military organization is often responsible for the life of its soldiers. (mardoto, yogyakarta, 15 september 2009)
