The Kaufman Assessment Battery for Children, Second Edition (KABC-II), measures cognitive processing, includes non-verbal sub-tests, and is increasingly used in low-and middle-income countries. While the KABC-II has been validated in the United States, a psychometric evaluation has not been conducted in Southern Africa. This study aims to establish the reliability and validity of the KABC-II among a sample of 376 primary schoolaged children in rural South Africa (7-11 years). We examined Cronbach alpha and conducted a confirmatory factor analysis. The battery showed good reliability (Mental Processing Index [α=.78]); and the originally validated structure of the KABC-II was maintained (χ 2 = 16.30, p=.432). Mean scores were low on the Planning sub-scale. On the Simultaneous sub-scale, the mean score was higher for the supplementary sub-test Block Counting versus the core sub-test Triangles. With translation and the inclusion of supplementary subtests, the KABC-II is an appropriate assessment to use in this context.
