The Internal Audit Directorate (IAD) was borne out of the Public Sector Modernization Project (PSMP) as one of the pillars of strengthening the accountability framework of the public sector. A primary objective of PSMP was to enhance public sector accountability by strengthening the government financial management controls including internal audit units across government.

Consequently, the IAD was established within the Public Expenditure Policy Coordination Division (formerly Financial Management Division) of the Ministry of Finance and The Public Service. Its mandate is to strengthen Internal Audit Units within Ministries and Departments of government through the provision of institutional support, technical assistance, and professional development opportunities.

The Internal Audit Directorate acts as a unifying point of reference for the government internal audit community. The Internal Audit Directorate acts as a unifying point of reference for the government internal audit community.
