Validating Panga Munthu Test and Porteus Maze Test (wooden form) in Zambia

This study aims at validating two non-verbal, non paper-and-pencil tests, namely Panga Munthu and Porteus Maze (wooden form) on the basis of age differentiation and school performance. The subjects included Zambian school children from an intellectually average group aged 7–8 years, 9–10 years and 11–12 years; and also 11–12 years-old bright and dull school children. The results show that the two tests differentiate the three age groups, but not the bright, average and dull 11–12 year old children. The tests in their present form thereby seem to measure some factor which matures with age, but they are not useful at predicting school performance. In Africa, especially rural Africa, intelligent behaviour is not usually measured by acadmic excellence. A study of the relationship between these tests and the African criteria for intelligence is recommended.
