As part of a larger study on academic dishonesty, this paper aims to be a simple investigation of students' opinions on some ethical issues, such as cheating in exams and plagiarism in assignments. The main goal was to explore the level of awareness of cheating and plagiarism, the frequency of these dishonest behaviours, students' attitudes toward cheating and plagiarism and differences between demographic variables and the three dimensions mentioned above. This study was conducted through a questionnaire completed by 138 first-year engineering students at a university in Romania. The study showed that cheating and plagiarism practices are sometimes common among students; at the same time, it is necessary to increase students' awareness and attitudes in order to combat such misconduct. Also, students' ethical values and actions are in dissonance. The differences in gender and residence area of students are insignificant. The paper recommends that different actors collaborate to continuously educate and discourage students from engaging in academic dishonesty.
