1.1 BACKGROUND OF THE STUDY
Internal audit had been defined “as an independent appraisal function established
within an organization to examine and evaluate its activities as a service to the
organization”. Internal auditing is a process generally adopted towards ensuring
and safeguarding of resources and promoting operational efficiency in
organizations. The responsibilities for effective internal auditing normally rest on
with the internal auditors who in turn rely a great deal on the soundness and
effectiveness of internal control system.
The business world is developing so in the complex nature of the organizations.
This complexity of modern organizations and hence the management has led to the
much broader role at the internal audit. The role of internal audit is fast moving
from mere checking of documents and physical duties to analyzing the ability of
organization to react to changing circumstances.
Auditing for the public sector is aimed at prevention of mistakes, shortcomings and
misdeeds in the public administration. The internal audit has become a good
control measures that can foretell all the incidence of fraud and misappropriation
of fund in government ministries if properly put in place.

1.2 STATEMENT OF THE PROBLEM
Many business organizations are rapidly assuming complexity resulting to
remarkable reliance to internal audit and management as a wider range area of
control.
In spite of the existence of internal audit departments in organizations, it is often
argued that the rate of fraud and misdeeds is still on the increase, particularly in the
public sector. Some people argues that the internal auditors are creating more
problems than they are solving, others see it as tools for witch-hunting and
therefore sees them as unnecessary evil.
The internal control system in Nigeria public sector may be insufficient based on
some predicaments.
Lack of proper segregation and proper assignment of duties as well as
shortage of qualified staff to carry out internal audit and accounting duties.
Lack of implementation of routing audit report by appropriate authorities.
Inadequacy of internal control system leading to improper investigation.
The above reasons greatly affect the effectiveness of internal audit in the public
sector. This gives the researcher the impetus for undertaking a study on this study
with a view coming up with solution of those challenges.

achieving the purpose of a research problem. However, appears to be inhibiting the
proper discharge of the role of internal auditing in the Nigerian public sector due to
the necessity for public Accountability. Many people do not know why internal
audit department should exist and it should be part of internal control in public
organization.
The research project is expected to achieve the following objectives:

as well as shortages of staffs to carry out audit duties.
