This research work deals with the challenges of internal audit function in the Nigerian public sector with reference to Kaduna state ministry of finance. Internal auditing is a process generally adopted towards ensuring and safeguarding of resources and promoting operational efficiency in organization. The objective of this study has been to evaluate the internal control system in the Nigerian public sectors, to ascertain the non- implementation of routine audit report and the lack of proper segregation and assignment of duties. In recent times, a combination of forces has led to a quiet revolution in the profession. Government moving towards democracy must demonstrate accountability in the use of public money and efficiency in the delivery of service. In many cases internal control system are weak, staffs are poorly paid making them unmotivated, coupled with non-implementation of routine audit report by appropriate authorities. The Responses from staffs were analyzed using relevant statistical tools from which three hypothesis were formulated and tested using Z-test statistics, while questionnaire were analyzed in tabular form using simple percentage. It was discovered that the internal audit is facing a lot of challenges which includes inadequate staffing, lack of independence, lack of facilities to carry out audit function and also poor funding. As a result of some of these challenges the effectiveness of the internal audit in the Nigerian public sectors, has been hindered as well as the organizational change it can bring to its environment. I recommend that for internal audit to be effective, it must be a completely independent group, adequately funded and equipped with qualified internal auditors as well as sufficient opportunities for internal auditors to become qualified.
