In this study, an assessment scale for evaluating the experimental design ability of elementary science teachers was constructed based on primary trait analysis. This assessment scale contains three first-level indexes and eleven second-level indexes. The corresponding weights of indexes were determined by the objective weighting method. The scores of all the descriptions of the indexes were also assigned. After a trial test, this assessment scale was verified to be reliable and valid for evaluating the experimental design ability of elementary science teachers.
