The purpose of this study was to build a model for classification of motor and functional fitness in adolescent female students. To achieve this purpose, girls in 7th (n= 31), 8th (n= 26), and 9th grade (n= 28) were recruited with appropriate parental consent. To build the classification model, each adolescent performed and number of motor tests and the Stange, Genchi, Serkin tests of functional state. Canonical discriminant function analyses were conducted to determine the motor and functional fitness contributions. Two significant functions (p<. 001) resulted with the first function explaining 86.8% and the second 13.2% of the variance between grade levels. Based on the model, it was possible to classify girls’ grade and thus biological age based on the performed tests. Structural coefficients from the first canonical discriminant function pointed to substantial difference between girls in 7th grade compared to 8th and 9th grade at the end of motor coordination’s development as well as speed, power, and Stange’s test results. Structural coefficients of second canonical discriminant function pointed to substantial difference between girls in 8th and 9th grade based on static and relative arm muscle strength. For improving and fully developing the pedagogic control of girls’ motor and functional fitness, the first discriminant function should be used as it explained most of the grade differences.
