Raven’s progressive matrices (RPM) are among the most frequently used tests of general intelligence. Coloured progressive matrices (CPM) were designed particularly for assessing cognitive abilities of preschool children. The specific feature of CPM, compared to other RPM tests, is that solving items requires processing like global pattern apprehension, mirroring, repetition etc., rather than analogical thinking and discovering abstract rules in proper sense. We shall present the results of a psychometric analysis of responses of 905 2-, 3- and 4-year old children. The results show an increase of both reliability and unifactorial homogeneity with age. Nevertheless, the items could be scaled according to the Rasch model reasonably well. The relation between item parameters and item content proved to be quite consistent. Finally, the implications of the results for the early assessment of intelligence shall be discussed. Possibilities of a further development of CPM or similar tests, respectively, shall also be outlined.
