The aim of this study was to determine the effect of project approach-based education on cognitive abilities and scientific process skills of six-years children. A pretest-posttest-retention test control group quasi- experimental design was implemented in this study. Two kindergartens were involved, determined by simple random sampling and with similar features according to teacher and director views. In order to collect data, General Information Form, Cognitive Ability Test Form-6 to identify children's cognitive abilities, and Scientific Process Skills Test were utilized. At the end of this study, it was found that the project approach-based education administered caused a significant difference in cognitive ability and scientific process skills in favor of the experimental group of children and had a middle effect size. The difference between the post-test and retain test mean scores of the children in the experimental group were insignificant, and the effect of the applied education continued.
