Understanding the COSO framework and knowing which GASB standards apply is the necessary first step in implementing internal controls. Implementing the COSO framework is particularly challenging in a small business office where the SBO takes on multiple roles, staff turnover is frequent, and the audit cycle is continuous.

This article, a follow up to The Fundamentals of Internal Controls  and Beyond the Basics: A School Business Official's Guide to Internal Controls and Audit Requirements, gives SBOs the order of operations: what to do first, what to prioritize, and what compensating controls look like when textbook solutions aren't available.

Let's start with the 10-step order of operations: 

1. Set the tone at the top. Before a single procedure is written, the board and superintendent must visibly commit to written codes of conduct, clear lines of authority, and consistent enforcement. The SBO cannot build a control environment alone  it begins with governance.  

If leadership circumvents established procedures, no downstream control compensates for it. Consider asking the board to adopt a code of ethics and conflict of interest policy as the starting point for each new fiscal year.  

2. Prioritize risk. Not every process carries equal risk. Start where exposure is highest: cash receipts, student activity funds, payroll, purchasing cards, and federal grant compliance. These five areas generate the most recurring audit findings in school districts and carry the greatest reputational consequences when controls fail. Map these first before expanding to lower-risk processes. 

3. Know your control types. Every high-risk area needs 

  • Preventive controls stop errors and fraud before they occur — dual signatures, pre-approval requirements, access restrictions, and segregation of duties. 

  • Detective controls identify problems after they occur  monthly bank reconciliations, supervisory reviews, exception reports, and bank statement analysis. 

In small offices where full segregation of duties isn't possible, compensating controls substitute: The SBO opens mail independently, reviews bank statements directly or approves all wire transfers personally. The control must exist even when the staffing doesn't support the textbook design. 

4. Document your risk assessment in writing. The 2025 Green Book requires that your annual risk assessment be documented, not just performed. Explicitly address fraud, improper payments, information security, and per GASB 102, concentration and constraint risks. A risk assessment that lives only in the SBO's head does not meet the standard.  

5. Write procedures, not just policies. A policy states what should happen. A procedure describes exactly how, by whom, and when. Every high-risk process needs a written procedure. Review and update procedures annually — or whenever a significant operational change occurs, a new GASB standard takes effect, or a technology system changes.  

6. Cross-train staff. Cross-training is simultaneously a continuity measure and an internal control. Irregularities become visible the first time a different employee performs a task. Assign backup staff for every critical function — payroll, bank reconciliations, accounts payable, and student activity fund accounting. 

7. Build controls for new GASB standards before the audit. When a new GASB standard takes effect, your first question should be "What new control does the standard create?" — not just "How do we book this entry?" Build the reconciliation, approval workflow, and documentation procedure before your auditor asks for evidence. 

8. Establish an anonymous reporting mechanism. Approximately one-third of fraud is discovered through tips. COSO Principle 15 requires an external communication channel — staff must be able to report concerns without fear of retaliation. A whistleblower hotline, anonymous suggestion box, or third-party reporting service satisfies this requirement. If staff cannot safely report a concern, the control environment has a material gap regardless of what the policy manual says. 

9. Review technology access controls annually. System permissions, user access rights, and IT authorization are internal controls. Review who has access to your financial system, payroll platform, and student activity fund accounts at least annually. Terminate access immediately upon employee departure. With cloud-based systems expanding under GASB 96 and AI tools entering school administration, technology general controls are no longer optional. 

10. Own your audit findings completely. When a management letter finding lands on your desk, develop a corrective action plan with assigned owners, clear deadlines, and a documented follow-up mechanism. Track every finding to completion. Close it before the next audit cycle begins. Remediation is not a clerical task — it is a professional obligation under ASBO International Professional Standards.

This third article in a series on internal controls for school business officials provides a 10-step process for implementing internal controls.

Where to Start 

The standards tell you what is required. The frameworks tell you how to structure it. These 10 steps give you the order of operations to make it real in your district — starting with the highest-risk processes and building outward, one control at a time. Every district is different. Every business office has different staffing, systems, and risk exposure. What doesn't change is the obligation: design the control, document it, test it, and own the result.
