As a theory-driven intelligence test, Das-Naglieri Cognitive Assessment System (DN CAS) is widely used in the educational and clinician settings in North America. The DN CAS had been translated and revised into Chinese version, and it showed good reliability and validity among Chinese children in the elementary school and the middle high school. However, it was unknown whether DN CAS could be applied to Chinese preschool children considering a separated version of DN CAS used for ages 5-7. Therefore, this study aims to measure the psychometric properties of the DN CAS in a Chinese preschool sample. The participants were 246 normally developed children (101 boys and 145 girls) recruited from four kindergartens in Shanghai and their mean age was 66.18 months (SD = 3.92 months). They were assessed on twelve tasks of DN CAS for ages 5-7 and Test of Early Mathematics Ability 3rd (TEMA-3). Criterion-related validity was evaluated by examining the correlations between scores of subscales in DN CAS and the score on TEMA-3. Confirmatory factor analysis was conducted to examine the construct validity of DN CAS, and the model of Planning, Attention, Simultaneous processing, and Successive processing (PASS) was compared with other three competing models to determine which provided the best fittings in the present sample. The results showed all tasks in DN CAS had good internal consistency reliability (Cronbach’s αs ranged from .70 to .89), and the subscale scores and full score of DN CAS moderately correlated with scores on TEMA-3 (rs ranged from .53 to .75, p<.001). The current Chinese preschool sample demonstrated a PASS four-factor solution for the children’s cognitive performance (χ2/df = 1.889, GFI = .940, AGFI = .902, CFI = .965, RMSEA = .060), and significant difference was found between PASS and a (PA)SS three-factor model (?χ2/df = 9.051, p<.05), although (PA)SS model was also fitted well in the present sample. These findings suggested that DN CAS had good reliability and validity, and could be applied to evaluate the cognitive performances of Chinese preschool children. The four-factor structure of the DN CAS was similar to the factor structure of the DN CAS version for ages 8-17.
