The document provides an introduction to auditing principles and practices. It defines auditing and distinguishes it from accounting. Auditing involves accumulating and evaluating evidence to determine if information matches established criteria, while accounting identifies, analyzes, records and communicates financial information. The purpose of auditing is to provide reliable financial information for decision making and ensure accountability. There are three main types of audits - financial statement audits, compliance audits, and operational/performance audits. Auditors can also be independent, internal to an organization, or from the government.
