The importance of fostering critical thinking (CT) in community college education has been recognized highly worldwide. However, limited studies have been conducted to investigate CT abilities among community college students in the Asian context. A cross-sectional correlational study was conducted with 209 Chinese community college students to assess the levels of CT cognitive skills and CT dispositions and to identify the associated factors. The California Critical Thinking Skills Test (CCTST), California Critical Thinking Disposition Inventory (CCTDI), and a questionnaire on the students’ socio-demographic and academic profiles were used. The results showed that the average level of CT cognitive skills was 17.82 ± 4.10, which was at the upper end of the moderate range. For CCTDI scores, the mean value was 278.81 ± 22.61 and positive disposition towards CT was shown in four subscales: open-mindedness, analyticity, confidence in reasoning, and inquisitiveness. From regression analysis, HKDSE total score (i.e., university entrance examination total score), CT subject grade level, CCTDI truth-seeking, and CCTDI analyticity were identified as the four significant factors associated with their CT cognitive skills. The findings provide significant implications when reviewing the program design and curriculum as well as the addition of CT elements in a separate course to promote students’ CT abilities for sustainable development.
