This paper discusses the potential utility of WISC-III in identifying individual characteristics of Japanese children demonstrating proficiency in math or science. Previous studies have suggested that gifted and talented students exhibit high verbal performance in IQ tests, while other studies have shown diversity in their ability. In this study, data gathered using the Wechsler Intelligence Scale for Children: Third Edition (WISC-III; Japanese WISC-III Publication Committee, 1998) with children who were good at mathematics or science were analyzed to identify the intellectual characteristics of those children. The children were participants in one of the national science projects. The data were analyzed for two purposes. The first purpose was to reveal the overall characteristics of those in the project that were good at math or science. Descriptive analysis revealed that the proportion of superior and above scores in each IQ test was higher than the theoretical proportion. A hierarchical cluster analysis with index scores revealed four different characteristics of children. The result suggested diversity in children's intellectual ability. The second purpose was to explore the differences between children in introductory courses and those in advanced courses. Comparison between the IQ scores of those children revealed that the overall IQ of advanced course students was higher than that of introductory course students.
