Abstrakt:
The article presents theoretical and psychometric study of The Sense of Efficiency Test. It contains the results of standardizing research reconstruing the process of building a tool and consecutive stages of its empirical verification. It also contains information on the conditions in which The Sense of Efficiency Test should be applied in order to provide a high level of internal relevance for the research. The process of constructing and validating the research lasted 6 years and was based on almost 1,5 thousand random sample. In the period of 2006 through 2012 The Sense of Efficiency Test was applied in various research programmes which continued to test its relevancy and provided material to update the norms for overall population and the population of teachers.
