Directive controls ensure a particular outcome is achieved. Examples include guidelines, training and incentives.
Preventive controls are designed to reduce the chance that errors or irregularities may occur. For example, reading and understanding policies and procedures or approving payments before they are processed. Additional examples include the tone at the top, authorization, segregation of duties and password protection.
Detective controls are designed to detect errors or irregularities after they have occurred so they can be corrected. Examples include reconciling the bank statement and performing periodic inventories of equipment.
Corrective (or compensating) controls correct undesirable outcomes that have occurred or reduce risk to an acceptable level when other controls have failed or are not cost-effective. Examples include close supervision and management review.
Everyone plays a part in the district’s internal control system. Management ensures that controls are in place and every employee makes sure the internal control system functions by following the controls and reporting any breakdowns in them. Internal Audit examines the adequacy and effectiveness of the district’s internal controls and makes recommendations where control improvements are needed.
