Evaluating children's art works is a procedure that enables educators to continuously monitor and assess all areas of the child's abilities by observing children's art work and the products of that work. To use evaluation, as a complex action, preschool teachers must know the stages of child development and the stages of development of children's drawings. This research aims to determine whether educators of preschool children use procedures for evaluating children's art works, how often they do them, and for what purpose. Also, the research examines educators' attitudes about what criteria educators are guided by when evaluating. The sample of respondents consists of preschool teachers employed in kindergartens throughout Croatia, and the number of respondents is 45 preschool teachers. The instrument that will be used in this research is an online survey that was created for the purpose of researching educators' views on the importance and method of evaluating children's art works. The results of the research were descriptively processed and gave us the information that educators use the method of evaluating children's art works, not only for the purpose of assessing artistic and creative abilities, but also fine and gross motor skills, cognitive development and speech-language development.
