The Wechsler Intelligence Scale for Children-Revised (WISC-R) has established itself as a powerful clinical and diagnostic tool in the areas of educational assessment and the appraisal of exceptional children. A stratified sampling plan was adopted to insure that the normative sample would include representative proportions of various classes of Chinese children in the Taiwan area. The variables considered were: age, sex, geographic region, occupation of parent, and urban-rural residence. The first Chinese revision of WISC was revised for use with Chinese children aged 6(1/2) through 15 years in the Taiwan ares. The standardizational sample included 100 children in each of ten age groups, ranging from 6(1/2) through 15(1/2) years. The total sample contained 1000 cases, with 900 boys and 500 girls. The statistical properties of this Scale were summarized as follows: (1) The spilt-half coefficient of Full Scale IQ was. 94. (2) The stability coefficients of Full Scale IQs were. 91 in the 9(1/2) age group and. 95 in the 12(1/2) age group. The 30 children from each of two selected age groups (i.e., 9(1/2) and 12(1/2) years) in the standardization sample were retested after an interval of about seven weeks. (3) The standard error of measurement (SEm) of the scaled score on each subtest and of the three IQs were obtained to indicate the band of error surrounding a teat score. (4) The intercorrelations of the twelve subtests for each of the ten age groups were also calculated. (5) The coefficients of correlation of Full IQ on this Scale with the Standford-Binet IQ were obtained for 8(1/2) age group (r=.83) and 13(1/2) age group (r=.89).
