What is an Audit?

What is an Audit?

An internal audit involves reviewing county operations and procedures, office transactions or financial activities which is typically done by looking at cash receipts, disbursements (money allocated and spent by a department) or changes in fund balances (the individual financial accounts run by the county, i.e. general fund).  Audits are governed by professional associations of industry professions who set guidelines for how to properly conduct an audit.  These organizations include the Government Auditing Standards Board (GASB), American Institute of Certified Public Accountants (AICPA) and the Association of Certified Fraud Examiners (ACFE). There are four types of audits, financial, performance and compliance, these audits are conducted to ensure that county offices have accurate finances, that their programs are having the intended result and are operating as effectively as possible. 

These audits often result in finding and recommendations on how to improve a specific function or save money. The final type of audit is an Agreed Upon Procedure Audit which can be requested by departments, officials or members of the public.  These audits don’t result in findings, but look to answer a specific question made by the requesting party.  Audits are scheduled based a county-wide assessment of risk performed by office staff.  The staff will look at time since the last audit, the legal requirements mandating audits and staff turnover to determine when an audit is needed most.
