The article is devoted to the substantiation of the technology of screening of the physical condition of boys aged 15-17 years in the system of pedagogical control; it was developed the structure of the technology, the main components and their contents on the basis of determining of the informative indicators of physical development, morphofunctional state, physical fitness and working capacity of boys. On the basis of the results of the factor and correlation analysis, there were identified the informative indicators mostly characterizing the physical condition of boys. With the help of regression analysis, it was developed an express system for assessment of the physical condition of boys, its informativeness and validity were determined. The proposed screening system provides for an in-depth and express assessment of levels of the physical condition of boys aged 15-17 years and provides the opportunity to carry out the previous and current pedagogical control, to differentiate and individualize physical loads, to provide theoretical and practical recommendations, to select adequate means and methods for increasing the physical condition level
