Objective: This study was conducted to evaluate the psychometric properties of the Raven Coloured Progressive Matrices (RCPM) and the Test of Nonverbal Intelligence - 4th edition (TONI-4) among Malaysian primary school children. Methods: A sample of 306 students with mean age of 10.3 (SD = 1.76) from Kuching, Kota Samarahan and Tebedu area in the State of Sarawak participated in this study. Participants were recruited based on multistage sampling. The schools were randomly selected, whereas participants were recruited based on convenience sampling. The test was administered face-to-face with the students. We administered all three sections of RCPM (A, AB and B) and we only administered Form A of TONI. TONI and RCPM were re-administered 14 days later. The same participants were given all three sections of RCPM and both Forms A and B of the TONI. Results: Both RCPM and TONI-4 showed good construct validity (ranging from r = .56 to r = .77 for RCPM and r = .85 for TONI-4) and good concurrent validity. Test-retest reliability for both measures showed a good correlation (from r = .60 to r = .78 for RCPM and r = .77 for TONI-4). Conclusions: The present findings suggest that RCPM and TONI-4 have good psychometric properties for testing the non-verbal intelligence of Malaysian primary school children.
