The purpose of this study is to identify nursing educators' responsivity to the ethical principles in nursing education and the unethical instructor behaviours they have experienced or witnessed. This study, which is descriptive in nature, was conducted with 134 volunteer nursing educators who work in nursing schools providing education at both undergraduate and graduate levels in Turkey. The data were collected through a questionnaire and analysed using SPSS 15.0 package programming. Results were obtained using numbers, percentages, descriptive statistics, Chi-square test for the variables identified in census, dependent and independent t-test, and variance analysis for the measured variables. It was found that although the instructors participating in the study took ethical principles into consideration while doing their duty, they reported to have witnessed or experienced unethical instructor behaviours. Besides, the proportion of unethical behaviours that were witnessed by the participants was always higher than the ones that were experienced.
