Imagination is the ability of envisaging something that does not exist at the time being. Since 5-6-year-old children get through the pre-operational stage of Piaget's [2004. "Çocukta Zihinsel Gelisim" [Intellectual Development of Child] (2nd ed., H. Portakal, Trans.). Istanbul: Cem], they believe in empirical facts. Hence, Kujawski's Test of Creative Imagination (TCI) is not suitable to the children aged 6 years and younger. In this study, Kujawski's TCI was tried to be made suitable for the age group of 5-6 years. For this purpose, 204 children aged between 5 and 6 years attending the kindergartens, selected by using simple random sampling method in the city centre of Denizli Province, Turkey, were included in the study. At the end of the study, TCI was found to be a reliable and valid assessment instrument for children in the age group of 5-6 years. The 6-year-old children made more ideas and more detailed constructions than the 5-year-old children.
