Internal Audit

Two people shaking hands over documents
The Internal Audit Department will follow generally accepted auditing standards and the professional practice standards made by the General Accountability Office (GAO), commonly referred to as the “Yellow Book,” and the Institute of Internal Auditors (IIA), also known as the “Red Book.”


Internal Audit Protocol

In Summer 2008, Alamo Colleges' Chancellor issued a protocol for the District personnel regarding his support for the internal audit function established by the Board of Trustees. The Chancellor's Protocol Document was issued to further clarify for staff the general audit process and his expectations for cooperation and collaboration. Internal Audit distributes copies of the protocols during entrance conferences as needed.
