The purpose of this cross-sectional study was to examine the developmental trajectory of creative potentials of Polish students. A total of 1,522 Polish students aged between 7 and 18 from lower and upper primary school, middle school, and high school participated in the study. Creative potential was measured by means of the Test for Creative Thinking-Drawing Production. The findings showed that older students achieved higher scores than the younger ones, drops in mean scores among students aged 13 and 16 were noted, and levelling of scores was found among students aged from 10 to 13, with a slight drop at the age of 13. Moreover, a phenomenon was discovered which was described as a "mini plateau," i.e., an emergence of similar mean scores in 2 consecutive age groups. Possible explanations of the results are discussed, including interpretations in the context of the CMC and educational and environmental conditions which act as inhibitors or stimulators of the development of creative abilities.
