dc.description.abstract Occupational therapists routinely make use of the Test of Visual Perceptual Skills - Third Edition (TVPS-3), the Developmental Test of Visual Perception - Third Edition (DTVP-3) and the Developmental Test of Visual-Motor integration - Six Edition (Beery VMI-6) to determine visual perception and visual-motor integration (VMI) dysfunction. This study aimed to determine the validity and reliability of the TVPS-3, DTVP-3 and Beery VMI-6, on a sample of six to nine year old South African children. The scores for the typical children attending a mainstream school fell within the norms reported for children in the USA for all three tests. The DTVP-3, TVPS-3 and Beery VMI-6 were found to discriminate between children with and without a specific learning disability. All three assessments were found to have low levels of sensitivity, however were found to exhibit adequate levels of reliability. With the exception of the visual closure subtest on the TVPS-3 and DTVP-3, the tests cannot be used interchangeably but are all suitable for use with South African children from middle socio-economic backgrounds and can be used to identify visual perceptual and VMI dysfunction. This study was limited by a few factors such as that not all learners with a specific learning disability had visual perceptual problems, the participants used in this study only represented one region of Johannesburg and one province and lastly only learners aged six to nine years were included in this study. Further research on a more representative sample of South African learners is recommended as socio-economic status and environmental conditions have been shown to affect the performance on these tests. en_ZA
