Critical thinking in nursing education is considered as a central skill in the development of nursing profession. Critical thinking has such a considerable significance that the US National Nursing Board has included it as a mandatory measure for the certification of nursing faculties.Program evaluation: In this survey research the statistical population consist of nurses in Shiraz selected hospitals. And the sampling was done in convenience method using 107 individuals.The data collection tool is Wayne's questionnaire and the critical thinking standard questionnaire of California form B. Afterwards, it was analysed , using SPSS 22 software, descriptive statistics and Pearson correlation coefficient.Findings: Critical thinking skills of the studied units were assessed an average of 92.8 at weak level and resistence to change was discoverd 16.63 at moderate level. Pearson correlation coefficient explored that there is no significant difference between the two variables of critical thinking skills and resistance to the changes in the studied units (P> 0.05, r = 0.151). However, there is a significant and direct relation between the two variables of critical thinking skills and resistance to change in nurses with a Masters degree (P <0.05 and r = 0.686).Conclusion: one shall not expect that nurses with a higher critical thinking skill will necessarily have less resistance to change .Therefore; nursing managers do not need to consider the critical thinking skills of nursing workers in making changes.
