Definition of Internal Audit

The Internal Audit function, as defined by the Institute of Internal Auditors (IIA) as: "an independent, objective assurance and consulting activity designed to add value and improve an organization's operations. It helps an organization accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, internal controls, and governance processes."

Professionalism and Code of Ethics

The Office of Internal Audit (OIA) will adhere to District policies and regulations, applicable federal and state laws, governing regulations and guidelines, IIA's Code of Ethics, and International Standards for the professional practice of Internal Auditing (Standards).

The OIA is expected to uphold the following Code of Ethics and rules of professional conduct:

  • Integrity – Establish trust, perform their work with honesty, diligence, and responsibility;
  • Objectivity – Assess information, be open and maintain impartiality;
  • Confidentiality – Protect information, never use for personal ends, disclose only with proper authorization;
  • Competency – Apply appropriate knowledge, skills and experience, and continue professional development by improving proficiency and effectiveness of their services.

District Commitment to the Mission of the OIA

The Tucson Unified Governing Board is committed to a model of ongoing continuous improvement in meeting its goals; a fully independent OIA function is essential to this commitment.

Tucson Unified School District's (the District's) OIA is charged with evaluating and contributing to the improvement of the District's governance, risk-management and control processes by using an independent, objective, and systematic risk-based approach.

The OIA will assist the District by performing assurance and consulting audits, identifying potential risks, accessing internal controls, governance processes, and assisting in identifying operational and compliance issues.

The mission of the OIA is consistent with the IIA, and the Generally Accepted Governing Auditing Standards (GAGAS):

perform assurance and consulting audits that evaluate efficient use of resources, effectiveness of operations, compliance with internal controls, and adherence to District policies and procedures.

For the OIA to be effective it must build and maintain strong constructive relationships with the Superintendent or designee, and other stakeholders within the District. To operate at the highest level, it must have clearly defined and articulated guidance from the Governing Board and the Superintendent.

Maintaining the Independence of the OIA

For the OIA to achieve organizational independence, the department must have direct and unrestricted access to the Superintendent and individual members of the Governing Board, however routine contacts with the Governing Board may take place through the Governing Board's representative on the Audit Committee.

Accordingly, the OIA shall report administratively1 to the Superintendent and functionally to the Governing Board, thus maintaining the independence necessary to ensure the accountability and operational integrity of the OIA. The effectiveness of the OIA rests with its independence and support from the Superintendent and the Governing Board; they provide the authority and support to ensure the OIA has access to all areas of the District in order to perform the OIA duties.

The OIA will confirm their independence annually by signing the independent internal audit certificate and providing a copy to the Audit Committee, the Governing Board, and the Superintendent.

1 Administrative functions including day-to-day supervision, such as approving time off and scheduling requests, facilitating the Governing Board's evaluation of the Internal Auditor, addressing any employee-related concerns the OIA may have, and providing any administrative support or access needed.
