Performance of older adolescents on the Bruininks-Oseretsky test of motor proficiency: A prelude to normative data

Based on the findings in this study, it is recommended that norms be developed on large samples of 15, 16, and 17 year old adolescents in order to enhance the application and interpretations of test data for these ages. It is also recommended that separate norms be established for each sex, since significant sex differences are indicated in average performance for motor items after the onset of puberty.
