Psychometric data are presented for the Raven Coloured Progressive Matrices (RCPM), shortened to series A and B. The data were derived from a sample of 2791 persons aged 55 to 85 years. Six 5-year age strata were equally represented, as well as both sexes. The distribution of educational attainment was representative for the elderly population. Norms were stratified for age and education; gender differences were too small to necessitate separate norms. Analysis of reliability according to Mokken's IRT-model indicated modest scalability, but high internal consistency. A loss of 2 to 4 points at retest (depending on personal characteristics) is interpretable as a loss of capacity. Ample attention is paid to qualitative aspects of test performance, but it is concluded that error analysis is mainly useful to detect positional preferences.
