-This study investigates firstly the relations between students" moral standards and acceptance of plagiarism, cheating, collaboration and equity of treatment, and secondly, the effects of educational experience and discipline on these factors. The participants were 357 university students, 183 enrolled in the teacher education and 136 informatics students and 35 students of cognitive science/consciousness. The instrument included 29 items and was found valid by factor analyzes. The relations were investigated with Pearson"s correlation and variance analyses (ANOVA) in SPSS. The results showed a close to zero relation between students" personal, conventional moral standards and their acceptance of plagiarism. Instead students" moral standards had significant relations toward cheating and equity of treatment. Dependent on educational discipline, teacher education versus informatics, norms and ethical value systems influence not only to what degree students find plagiarism unacceptable, but also in what degree they accept cheating and collaboration.
