Efficacy is a trait required in almost every profession today, and its sense is a dimension that affects the evaluation of work. In education, effectiveness is also expected, especially from academic teachers whose role often goes beyond the formal framework. Therefore, the issues of one’s own efficiency in relation to self-esteem seem to be of particular interest, as an attempt to show possible dependencies in this regard, all the more so since previous studies not always revealed such a connection. Therefore, the main research problem takes the form of the following question: Do relationships exist between self-esteem and a sense of one’s own efficiency among the academic teachers surveyed, and if so, what are they? Carrying out empirical research among the teaching staff of a military university, I decided to diagnose a specific military environment in this matter, which can be a real reference to similar analyzes carried out at other universities. I formulated my conclusions based on the results of research carried out using the diagnostic survey method at the War Studies University in Warsaw using standardized measuring tools and elements of descriptive and correlation statistics.
