The research aimed to investigate the critical reflection of nursing students at the Faculty of Nursing, Rajamangala University of Technology Thanyaburi during the 2021 academic year. A total of 169 students were selected as the specific purposive sample group who consented to provide data. The research used a questionnaire comprising personal information and the level of critical reflection analysis. The data was analyzed using frequency, percentage, mean, standard deviation, one-way ANOVA, and LSD post hoc test. The findings revealed that nursing students had a high overall level of critical reflection (mean = 3.93). When examining specific aspects, it was found that their technical rationality, reflectivity, and critical reflection were also high (mean = 3.91, mean = 3.95, and mean = 3.92, respectively). This research highlights the nursing students' capability for critical reflection, which can contribute to the enhancement of their learning and development of analytical skills.
