The objective of the study was to test the Coloured Progressive Matrices Test with regard to reliability and validity for the 3-9 age sample group because of the lack of diagnostic tools for the pre-school period. The sample group of the study was comprised of a total of 925 children with 433 girls (46.8%) and 492 boys (53.2%). Coloured Progressive Matrices Test reliability was analyzed by way of two split-half reliability and test-re-test reliability using Kuder Richardson-20 (KR-20) and Spearman-Brown Formula. The level of relationship between Coloured Progressive Matrices Test and Bender-Gestalt Visual Motor Perception Test and TONI-3 tests was determined via Pearson Product Moment formula for validity analyses. Afterwards, the age norms were determined as percentile values in accordance with the ages. The results obtained from the study provided psychometric data indicating that the Coloured Progressive Matrices Test is suited for the use by researchers.
