The evolution of computational techniques observed in the field of Virtual Reality enabled new ways of discussing and using information technologies in educational contexts. Given this scenario, it has emerged the need to verify the efficiency of virtual training techniques as well as to establish methodologies to evaluate the skills acquisition. This paper aims to analyze the contribution of statistical method for an evaluation methodology of the Sensory-Motor Skills acquisition in Three-dimensional Interactive Virtual Environments. To achieve these purposes, an experiment was conducted and an application was built based on an assessment conceptual model to verify the contribution of a statistic approach for the evaluation of virtual tasks. The results show that it is possible to evaluate virtual tasks discriminating a skilled and unskilled run profile, and at the same time, to compare the correctness degree and the accuracy of techniques used to classify tasks to a greater or lesser degree of skill.
