This study aims to show the role of organizational integrity in reducing financial and administrative corruption practices in Sudanese public sector institutions, while also highlighting the challenges of implementing it in this context. The study relied on the descriptive-analytical approach, combining the theoretical side (through reviewing literature, previous studies, and international reports) with the field side (an analytical study on a sample of staff from the College of Customs, Medical, and Technology Sciences in Khartoum State, including heads of accounting departments, accountants, financial managers, administrative managers, and internal and external auditors, during 2026, where 50 questionnaires were distributed out of a total study population of 57 individuals, and all were retrieved and valid for analysis).The primary data were collected through a questionnaire based on a five-point Likert scale and analyzed statistically using SPSS. This included calculating averages and standard deviations to describe the sample’s tendencies, using Cronbach’s alpha to check the tool’s reliability, and applying Pearson correlation and linear regression analysis to test the study’s hypotheses. The results showed a statistically significant positive correlation between the dimensions of organizational integrity (such as transparency, accountability, ethical leadership, internal control, and the implementation of codes of conduct) and the challenges associated with financial and administrative corruption practices, thus confirming the validity of the study’s hypothesis.

The descriptive results also showed that strengthening these principles reduces forms of corruption such as embezzlement, bribery, favoritism, and forgery. However, implementing integrity faces major challenges in the Sudanese context, mainly political pressures, external interventions, lack of political will, long tenure of leadership without rotation, security conditions and the ongoing war since 2023, and low salaries and incentives. Finally, the study recommends enhancing transparency and electronic monitoring mechanisms, building a sustainable ethical culture through regular training and safe reporting channels, strengthening the independence of oversight and judicial bodies, increasing salaries and incentives and linking them to performance and integrity, and establishing an independent anti-corruption commission in coordination with civil society and the media.
