Charles County Government's Internal Audit Office adheres to the Global Internal Audit Standards issued by The Institute of Internal Auditors (IIA), which require an external quality assessment at least every 5 years. 

A peer review determines whether an audit organization's quality control system is appropriately designed, fully implemented, and operating effectively. It also confirms adherence to established polices, procedures and professional auditing standards, ensuring consistent and high-quality audit practices. 

The Association of Local Government Auditors (ALGA) developed the Peer Review Program to help local government audit organizations meet the profession’s external quality assessment requirements.
