This instructional case encourages analytical thinking about internal controls in both the operations and audit of a small, not-for-profit organization. Students examine a control environment characterized by unauthorized expenditures, lack of documentation, and missing documents. Using the COSO (2013) framework, students demonstrate understanding of business processes as they identify internal control risks and deficiencies, and recommend control improvements. Auditing students additionally apply management assertions about financial transactions and assess auditor independence. Students gain practical experience in developing flowcharts of accounting processes and writing a management letter for a familiar organization: a preschool.
