Oladipupo (2005: 96), pointed out that internal audit is a managerial tool which functions by examining, evaluating and reporting on the adequacy of internal control as a contribution to the proper economic, efficient and effective use of resources within an organization.

Internal audit is a control which measure evaluates and reports upon the effectiveness of internal control, financial and otherwise, as a contribution to the efficient use of resources within an organization, which was stated by Nwabueze, (2000: 278). It is the requirement of the Companies and All Matter Act (CAMA) 1990, that management should keep and maintain accounts, which presents a true and fair view of the organization financial position which must be attested to by an external auditors report. To achieve this management do establish its own policies which all the operational and service units of the organization must comply with to assure itself that its policies and programme are properly implemented, management does establish various internal control system among which the internal audit.

Internal audit is an independent arm of the organization which help in appraising both financial and other operations with the specific purpose of rendering protective and constructive services to management. The proper administration of any organization is solely dependent on the management which sees to the effective and efficient utilization of the limited resources available to it through proper planning controls to ensure the realization of corporate objectives. With the growth in size and complexity of many organizations, the need for internal audit has correspondingly increased, so that it is today a major factor in establishing the quality of an organizations internal control system and its development.

The establishment of the internal audit is not required by law but is the brain-child of management with the specific objective of fulfilling its stewardship function. This is why the internal audit unit has been identified not only as an arm of management but also as an important tool the management uses in the discharge of its duties. This study will therefore go a long way to ensuring the efficiency and effectiveness of the internal audit. Thereby ensuring a sound and reliable control system.


The rationale for choice of the subject matter is the inability of management in ensuring a proper internal audit system coupled with the absence of a sound and reliable internal control system. Ojaide (200: 6) pointed out that the role of an internal audit department is to assist management in ensuring that the system of accounting, internal control and internal check are operating effectively and efficiency.
