What type of audit is conducted on a semiannual basis?

The correct answer is a workcenter audit, which is conducted on a semiannual basis. This type of audit focuses specifically on evaluating the performance, compliance, and system processes within a particular workcenter. The semiannual schedule allows organizations to conduct regular assessments and ensure that operations within the workcenter are meeting established standards and regulations.

Workcenter audits typically help identify potential areas for improvement and ensure that quality assurance measures are being followed effectively. By conducting these audits every six months, organizations can proactively address issues, optimize performance, and maintain accountability.

In contrast, other types of audits mentioned, such as program audits and special audits, are not typically scheduled on a semiannual basis, while annual audits are designed to be conducted once per year, which does not align with the semiannual timeframe of workcenter audits.
