Types of Audits Performed By the OAG
Financial Audits
Financial audits, which include financial statement and financial related audits, are
designed to provide reasonable assurance about whether the financial statements (or
schedules) of an audited entity are fairly presented in conformity with generally
accepted accounting principles.
Single Audits
Single Audits, which are financial audits performed in accordance with the Single Audit
Act of 1984, are designed to meet the needs of all federal grantor agencies and other
financial report users. Single Audits are financial audits which require additional study
and evaluation of the internal control structure and testing of compliance with laws and
regulations relevant to federal assistance programs.
Performance Audits
Performance audits, which include economy and efficiency and program audits, are designed
to provide an independent assessment of the performance of a governmental entity, program,
activity, or function to improve public accountability and to facilitate decision making
by parties responsible for overseeing or initiating corrective action.
Performance and Financial Audits
Performance and financial audits are designed to achieve a combination of performance and
financial audit objectives.
