This research conducts a thorough review of academic integrity in teacher education, analysing the prevalence, reasons, and solutions for academic dishonesty. From an initial 693 articles in Web of Science and Scopus, 23 were selected based on strict criteria, revealing issues like plagiarism and cheating among aspiring teachers. The study points to academic pressure, skill shortages, and confusion about integrity principles as key factors driving dishonest behaviours. It stresses the importance of comprehensive strategies to combat this, including ethics education, the development of detection technologies, and cultivating a culture that prioritizes honesty. With the rise of AI, adapting integrity measures becomes crucial. Future research should focus on innovative methodologies, the effectiveness of ethics programs, and the impact of technology on maintaining academic standards, highlighting the educational community's responsibility to promote an honest environment, essential for the credibility of future educators.
