The purpose of this research was to establish the hierarchical classification of expert model on fundamental methodological exercises for teaching of the movement of snow plow turn and snow plow bow in ski school. Participants were 307 skiing experts of varying degrees of cross-education from different states. Defined expert model of the 6 most important methodical exercises to teach the snow plow turn and 5 most important methodical exercises to teach the snow plow bow, was ranked by the ski experts of different levels of education. There rating was based on the importance of implementation in the methodology of teaching the novice skier. Using non-parametric analogue post-hoc analysis, i.e. Kruskal-Wallis test (H-test) and appropriate empiric level of significance (p), statistic significance of sums of ranks (R) of the most important methodical exercises for teaching snow plow turn and snow plow bow have been tested. In ranking of the most important methodical exercises for teaching both skiing figure have been established a statistically significant difference at the level of p <0.001. Reliability between the ski experts was examined using the Kendall Tau (τ) coefficient of concordance. Those variables which were not different in statistically significant way according to sums of rank were classified in one significant group, while variables which showed statistically significant difference were classified separately. Based on obtained significant differences in ranking importance methodical exercises for teaching snow plow turn and snow plow bow, and by the help of values of total rank sum, hierarchical classification among the differences had been successfully formed. This research makes a good basis for future works where skiing experts throughout the world should be engaged, and evaluation of hierarchical classification experts model of teaching snow plow turn and snow plow bow.
