The purpose of this study was to observe record and evaluate the psychomotor development and its relationship to children's gender and age on attending public and private kindergartens in Greece. The sample consisted of 898 children (487 boys' 54% and 411 girls 46%) aged 64 ± 9 months from 64 kindergarten schools. A set of 18 MOT tests Zimmer and Volkamer [1987. "Motor Test for Children Aged 4 to Six Years Old: MOT 4-6; Manual/MOT 4-6." Revised and Expanded Edition] was applied to evaluate psychomotor development. These tests were presented to children as a structured activity after telling the story of an adventure in the forest where the children were trying through the various tests to discover the hidden treasure. The results showed that the majority of children responded satisfactorily to the requirements of the game, with a small percentage of children failing to perform accurately, with a smaller percentage leaving the game without completing their efforts. No significant differences were found between boys and girls, but the groups of older children were found to perform better.
