Ethics is a multidisciplinary concept with strong ties to education. Ethics education, which is given directly or indirectly at all levels of education, is presented as teaching ethics at university level, school ethics and ethics education. University students receive ethics education either directly through courses with ethical content, or through the social atmosphere, teaching methods, social acceptance/rejection systems and/or educational culture. In teacher education, ethics has a special importance due to its relationship with the field of education and the teaching profession. In this context, thisstudy tries to understand how pre-service teachers perceive ethics thorugh the Mach IV scale, the effects on their ethics perceptions and the relationship between their attitudes towards teaching as a subject and ethics. The research was conducted at a state university in Istanbul. The participants of the study consist of 146 students from departments of primary education, social studies education, mathematics education and Turkish education. The effects of gender and department were tested to affect students' ethical perceptions. In addition, the relationship between students' attitudes towards teaching and their ethical perceptions was also analyzed. It was seen that the department and gender did not make a statistically significant difference on the ethical understanding of the students. In addition, there was no statistically significant correlation between the attitudes of the students towards teaching as a profession and their understanding of ethics. Only a statistically significant correlation was found between ethical tactics and attitude towards teaching. The findings were discussed in terms of teacher ethics and teacher ethics.
