A normative and reliability study for the Raven's Coloured Progressive Matrices for primary school aged children from Victoria, Australia

Abstract

Outcomes of a normative and reliability study on the Raven's Coloured Progressive Matrices (CPM) are reported for a sample of 618 children from Victoria Australia ranging in age from 6.00 to 11.92 years. Percentile ranks are presented for six age levels. Item analysis, internal consistency, and split-half reliabilities are also described. The CPM demonstrated good inter-item consistency and split-half reliability across the age levels. However, item analysis together with the reliability analyses indicated that the number of items in the CPM could be reduced without detriment to the test's reliability. The psychometric properties of the CPM are discussed and the norms are compared to previou..
