A dysfunctional educational system has been identified as one of the causes of academic dishonesty in the Eastern Europe. This paper describes a case study based on data collected at one Czech university (N = 660) and presents measures that have been taken at the institution after it. The case study combines quantitative self-reported data and qualitative data from students and teachers with hard data from the disciplinary committee. We analyse cases and types of breaches, identify characteristics of students that incline them toward cheating and investigate some of the reasons why. Our research confirms that the inconsistent approach of teachers is a contributing factor to students' propensity to violate academic integrity rules and identifies reasons for such behaviour. Teachers play a key role in prevention, it is their duty to report cases of suspected misconduct, but they need tools to improve the culture of academic integrity. This paper describes in detail the measures which have been at the given faculty as a solution to the identified problem, the authors believe that the presented measures might serve as an inspiration for policymakers on how to tackle the inconsistency of teachers' approaches to student misconduct.
