The Office of the Auditor General of Thailand or 'OAG' in short, is an independent body with broad powers and duties to audit all government offices, agencies and enterprises, and local government units to ensure control of the utilization of public funds. OAG is also obliged to submit audit reports, comments and remedial suggestions and recommendations on deficiencies detected in the course of audit to agencies concerned. OAG sets its own direction and scope of audits without interference and reports its annual performance directly to the Prime Minister.
OAG is headed by the Auditor General who is appointed by the Council of Ministers and approved by the Legislative Assembly. The Auditor General is a civil servant subject to the Civil Service Law and can be in his office until the retirement age of 60. The position of the Auditor General is that of the highest civil service level.
OAG currently has a total staff of 1,686 of which 1,546 are civil servants. The vast majority of these civil servants are auditors and the rest are clerical and other administrative support staff.
OAG operates through eight separate Divisions and nine Regional Offices as listed hereunder:
The State Audit Act of B.E. 2522 (1979), which repealed the Audit Council Act of B.E. 2476 (1933) and transferred all duties and powers of the Audit Council to OAG, has enlarged the OAG's authority with a view to enabling it to perform more complete performance audits. The legislation regarding performance auditing is described as follows: "....may examine the disbursement of money and use of other properties, and give opinion whether they are in compliance with the objectives, are economical and worthwhile and reach the target."
OAG has begun to engage in performance audits on a step by step basis since 1975. At that time no specific statute authorized such audits, but there was no prohibition against them and it was argued that the Audit Council Act could be interpreted to include performance auditing among the responsibilities of the office. The audits performed focused on procurement expenditure, asset utilization, custody and maintenance of assets, and on construction.
On the suggestion of the UN Interregional Adviser for Government Budgeting and Financial Management whose 2-week services in May 1978 were made available by the UNDP, OAG started taking further steps that were considered appropriate for developing the expertise for performance auditing. Initial efforts resulted in the conduct of performance audits of 6 pilot projects with the advise and guidance of a consultant on performance auditing made available for 7 months in 1980-1981 by the UNDP. Most of the audits focused on the efficiency, effectiveness, and impact of development projects. An Audit' team of 3-4 selected auditors from 4 divisions and 1 regional office took part in these audits. After the completion of the pilot projects OAG continues and gradually expands this type of auditing. A number of performance audits are scheduled to be carried out annually by every audit division and regional office, taking into consideration the present work pressures of the necessary financial audits and the limitations of staff.
In fiscal year 1983 (Oct. 1, 1982-Sept. 30, 1983), evaluations of the implementation of development projects under the poverty-stricken area development plan which cover 38 target provinces and are expected to benefit some 7 million poor people throughout the country by the end of the Fifth National and Social Development Plan in 1986 and the Rural Employment Generation Programme which aims at generating employment and supplementing the income of the villagers during the high-unemployment period were the more significant audits. The audits., dealt with projects such as construction of village water resources, bridges and roads, digging of canals for agricultural purpose and setting up of buffalo banks and livestock development.
OAG realizes that to be successful in extending its scope beyond financial audits to performance audits, it has to learn gradually. Furthermore, there are other variables that will contribute to the development of performance auditing. Among them are sound internal audit systems, development of performance indicators and management reporting systems, support for more staff, continued technical assistance from various international organizations and other Supreme Audit Institutions such as GAO, the Office of the Auditor General of Canada and so on. It is hoped that within a reasonable period of time OAG will finally be able to implement full-scale performance auditing that can cover many high priority projects annually.
