Where a questionnaire was designed containing a set of questions distributed to the sample of the study, and the results were tested based on the Statistical Package for the Social Sciences (SPSS). This paper came to the conclusion that the auditors of the Supreme Audit Institution in the State of Libya are aware of the importance of applying the standards of international disclosure and reporting to the institutions subject to audits. Moreover, these institutions are not based on accounting disclosure standards when preparing and presenting financial statements and reports, this reflected negatively on the performance of the Supreme Audit Institution (Audit Bureau) because of the absence of a lot of data and information that must be shown in the reports and financial statements.
