The aim of the research was to identify structure of body posture, as well as stastical significance of differences between clusters, upon the indicators of body posture, as well as to analyze types of body posture. Examinee sample included (N=132) pupils of primary schools in Valjevo, aged between 10-13. Five variables of body posture in frontal plane and four variables in sagittal plane, measured by Tribastoneu’s instrument -scoliometer Stastically significant bipolar linear discriminative function was isolated by algorithm of canonical discriminant analysis. Three variables in the frontal plane (asymmetric knee position, asymmetric leg joint position, and head position according to a vertical) and four variables in the sagittal plane (head position, shoulder position, pelvis position, knee position according to gravitation line) were of the greatest importance for the differentiation between the types of examinees. Sample results mostly coincide with the results obtained from the samples of previous research of the population that was subjected to analysis.
