ABSTRACT
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 nonimplementation 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.

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.

audit department should exist and it should be part of internal control in public
organization.
