The purpose of this study was to determine the cross-sectional similarity of the factor structure in the rating of manual skills of children. Fifteen variables were used; two were subjective ratings by the teachers, the rest were objective ratings. Subjects were 420 first-to sixth-grade elementary school children. The correlation matrices of the 15 variables for each grade were analyzed by the method of principal components. Six components were retained in each case. Factors for each of the first-to fifth-grades were orthogonally rotated to make them as similar to the sixth-grade factors as possible. In terms of the factor loadings, no meaningful differentiation was found in most rating variables, but a slight differentiation was noted in the variable on frequency of the successful threading of a needle, according to grade levels.
