The authors evaluated the adequacy of an extensive adaptation of the American Kaufman Assessment Battery for Children, second edition (KABC-II), for 6- to 10-year-old Kannada-speaking children of low socioeconomic status in Bangalore, South India. The adapted KABC-II was administered to 598 children. Subtests showed high reliabilities, the Cattell-Horn-Carroll model underlying the original KABC-II was largely replicated, and external relations with demographic characteristics and an achievement measure were consistent with expectations. The subtests showed relatively high loadings on the general cognitive factor, presumably because of the high task novelty and, hence, cognitive complexity of the tests for the children. The findings support the suitability and validity of the KABC-II adaptation. The authors emphasize that test adaptations can only be adequate if they meet both judgmental (qualitative) and statistical (quantitative) adaptation criteria. (Contains 1 table and 1 figure.)
