The aim of this study is to determine academic dishonesty behaviors based on the opinions of pre-service elementary and social studies teachers. This study was designed using a student self-report survey questionnaire. The sample of this study consisted of 445 pre-service teachers. The research data was collected using “the academic dishonesty behaviors opinion survey” developed for this research. The research data was analyzed using descriptive statistical techniques and chi-square test. Results indicated 23 items that pre-service teachers agreed on were about academic dishonesty. Of these 10 items were about academic cheating and 13 items were about plagiarism in assignments. The top three academic dishonesty behaviors based on participants opinion were respectively having another person take the test on behalf, stealing exam materials and handing in someone else's essay with his/her name on it. Most pre-service teachers did not accept 4 items as an academic dishonest behavior. These items were using old exam questions in order to prepare an exam, using someone else's notes in order to prepare an exam, to give information to other class students after taking the exam, and taking an exam after receiving information from students who already took the exam. In this study, another important finding was about gender differences; female preservice teachers showed more concern than male pre-service teachers about academic dishonesty behaviors. There were also a few limited significant differences both in grade and class level in all academic dishonesty behaviors.
