The main objectives of the long-term research, the partial results of which are presented in this paper, were related, among other things, to identification of the influence of experimental artwork classes on children’s artistic skills. The adopted research method based on analysis and interpretation of artworks regarding their compositional modality turned out to be the factor unmasking the difficulty in assessing children’s artworks. Therefore, the paper presents fragmentary results of complex research and demonstrates the divergence of marks given by a group of competent judges who used a structured tool.
