Intact classes of mentally retarded and nonhandicapped children were administered the Physical Dexterity scales of the System of Multicultural Pluralistic Assessment and the short form of the Bruininks-Oseretsky Test of Motor Proficiency. Separate discriminant analyses of each data set revealed that the subjects comprised four distinct levels of motor performance. Although overall predicted correct classification was above 65%, misclassifications occurred in each class. Differences resulting from the separate analyses suggest differential program placement for physical education. There is a tendency for the Physical Dexterity data to predict higher levels of motor functioning than the Motor Proficiency data for half of the mentally retarded children.
