The study compares the national versions of the WISC-III and the results of the standardizing researches carried out in Great Britain, German-speaking countries, the Czech Republic and in Slovakia. It brings support to the fact that despite a common cultural space in the European Union, the differences exist in the intellectual abilities of children of the groups surveyed. They may be ascribed to the different traditions and primarily to the different school systems existing in various countries. These facts are to be taken into account when intelligence is being measured and this also when nonverbal testing tasks are used.
