Rhythmic gymnastics is a combination of sport and art in which the ability of coordination is very highly positioned in the equation of performance specification. Since there is not a sufficient number of specific tests by which coordination could be assessed, both in the selection of children of potential rhythmic gymnasts, as well as in monitoring the training process, the main purpose of this paper is to construct a coordination assessment test that will be applied specifically to rhythmic gymnastics. The sample consisted of 93 students of the 3rd year of integrated undergraduate and graduate study at the Faculty of Kinesiology, University of Zagreb (average age 21 ± 1 year). In addition to the newly constructed test "Echappe" with rope (MKEV), three other tests were used: ground maneuverability (MAGONT), jumping hoop forward (MKOOPO) and back polygon (MREPOL). Microsoft Excel 365 was used to facilitate data preparation and visualization, while IBM SPSS Statistics 26 was used for statistical analysis, with arithmetic mean and standard deviation as descriptive indicators, Shapiro-Wilks test to determine distribution normality, Kruskal-Wallis test, with Bonferroni correction, for validation, and Fleiss Kappa for reliability determination, which was further determined by Spearman’s Rank correlation. After the analysis, the results showed that there is no evidence that the test "Echappe" with a rope measures the coordination required for success in rhythmic gymnastics and that further research is needed with redefined criteria that will contribute to improvement and better metric characteristics of the test.
