The aim of this work is to show the motor skills differences between 10-year and 15-year-old girls and boys. Particular attention is paid to the school years 2007-2012.For this survey, 608 children/adolescents of both schools, secondary school (167) and polytechnic school (441), were tested. The sample consists of 441 boys and 167 girls. The tasks were divided into eight stations, which were bilt; seven in the gym and one outside on the sports field.While the performance increase is noticable in the boys of the polytechnic school, the boys of the secondary school, however, were only in some areas better. In the areas of the 20-m sprint, medicine ball throw, reaction test and balancing, the results were worse than in previous years.For the girls of the polytechnic school, all areas test results consist of high points. The girls of secondary school, on the other hand, have better results only in some areas (reaction test, forward bending test, balancing and running testing). In the other tests, there was a slight deterioration (20-m sprint, throw medicine ball, standing long jump, twisting course).In summary, it can be said that both girls and boys of polytechnic school achieved high points in motoric skills tests. The results of the same motoric skills of the pupils of secondary school differ ? vary from area to area.
