On the basis of national research data on schoolchildren' achievements, the article deals with implementation of educational software in the process of teaching world study in primary school and different natural sciences in basic school. It has been established that educational software is often enough implemented during the classes on world study in primary school in comparison with natural science lessons provided in basic school. Primary educational software is regularly used in the city site, less frequently - in the regional centre and rarely in the rural area schools. On the opposite of the city site schools, basic educational software is widely employed in the rural area. The comparison of the rates of implementation of educational software during the different classes on natural sciences reveals that educational software is most frequently applied during the classes on biology, the least frequently - during the classes on physics.
