The goal of this research is to identify and explain the difference between elite junior guards, forwards, and centers based on descriptive statistics, correlative analysis and latent structure of the 13 standard parameters of situation-related efficiency. The sample consisted of a 108 examinees who are elite junior basketball players, who played an average of 8 minutes per game and more than 3 games, and were selected out of 11 teams that played 46 games in the European Junior Championship in Zadar, in 2000. For the purpose of latent structure analysis, we applied the confirmatory strategy of factor analysis. In doing so, the process was limited to extracting two significant factors by a method of main components with orthogonal varimax normalized rotation of the structure of manifest variables for assessment of situationrelated efficiency. The results of the mentioned analysis show that the parameters of situation-related efficiency differentiate players by positions, and indirectly determine tasks and assignments in the game that are apparent in the indicators of situation efficiency in the game.
