Overview
We are pleased to offer our annual report on the status of the County Auditor-Controller-
Treasurer-Tax Collector’s Internal Audit Division (IAD) in accordance with the International
Standards for the Professional Practice of Internal Auditing requirements. A report on the FY 2022-
23 Audit Plan is included on page 5, a summary of the FY 2022-23 Whistleblower Hotline Reports
is included on pages 6 and 7, and our proposed FY 2023-24 Audit Plan is included on page 8.
Purpose, Authority, & Responsibility
The Internal Audit Division exists to inspire and elevate public trust in government by assisting
and supporting the County, the Board of Supervisors, and other stakeholders in achieving their
mission with transparency and integrity. We accomplish this vision by providing reliable,
independent, and objective evaluations and advisory services which utilize a systematic and
disciplined approach to add value and improve operations. We contribute expertise in the
evaluation and enhancement of controls and other processes, minimization of risks, and
enhancement of operational effectiveness for stakeholders.
The authority for the Internal Audit Division is provided in California Government Code Sections
26881 and 26883. In Accordance with Government Code Section 1236, we follow the International
Standards for the Professional Practice of Internal Auditing (Standards).
Our responsibilities include maintaining independence and objectivity, continually enhancing our
skills and knowledge, and providing consistent, clear communication as we perform our work.
Our audit duties include the performance of:
Assurance Audits – the main purpose of assurance audits is to provide an
objective assessment of evidence and an independent opinion or conclusion
regarding an operation, function, process, system, or other subject matter. Such
audits may focus on the reliability of financial or operational information, on
systems of internal control over recordkeeping, and/or the adequate
safeguarding of assets. These audits may also include a review of controls
implemented to ensure compliance with policies, plans, procedures, laws, and
regulations.
Examples of assurance audits completed in prior fiscal years include:
Cannabis Tax Compliance Audits
Community Based Organization Grant Audits
Transient Occupancy Tax Collection, Reporting and Remitting Audits

Consulting Audits – Consulting audits are advisory in nature and are generally
performed at the specific request of a client. The nature and scope of the
consulting engagement are subject to agreement with the client.
Examples of consulting audits in prior fiscal years include:
Department of Social Services’ Workforce Innovation and Opportunity Act
Grant Audit
District Attorney Workers’ Compensation Insurance Fraud Grant Audit
In addition to our audit duties, the Internal Audit Division is responsible for:
Monitoring the County’s 24/7 Whistleblower Hotline, investigating and following
up as needed
Assisting in the preparation of the County’s Annual Comprehensive Financial
Report (ACFR) and acting as liaison with the external auditors

Reviewing departmental fee calculations for accuracy and appropriate
methodology
Managing the Countywide Cash Handling Policy, reviewing departmental cash

shortages
Consulting on internal control implementation and updates

Independence
The Auditor-Controller-Treasurer-Tax Collector (ACTTC) is elected by the citizens of San Luis Obispo
County, thus achieving organizational independence. The Internal Audit Division consists of one
Page 3 of 14
COUNTY OF SAN LUIS OBISPO
Office of James W. Hamilton, CPA

Michael Stevens, Deputy
Justin Cooley, Deputy
staff auditor and one Internal Audit Manager who report directly to the ACTTC. Both the ACTTC and
the Internal Audit Manager have unhindered access to the County Administrative Officer and the
Board of Supervisors.
Each year the ACTTC, Deputy Auditor-Controller, and individual members of the Internal Audit
Division affirm their independence by signing a Statement of Independence and Objectivity.
Likewise, Statements of Independence are completed for each individual engagement by team
members assigned to the engagement.
Internal Audit Division Charter
The Internal Audit Division Charter is the guiding document for our audit work. The Charter
includes the Core Principles for the Professional Practice of Internal Auditing issued by the Institute
of Internal Auditors. No updates to the Charter have occurred in the past fiscal year.
Quality Assurance and Improvement Program Results
The auditing Standards require that we maintain a quality assurance and improvement program
consisting of both ongoing and periodic assessments of our operations and audit work to
determine conformance with the Institute of Internal Auditor’s Definition of Internal Auditing, Code
of Ethics, and Standards.
External Assessment
The Standards specify that an external assessment, also known as a peer review, be conducted
every five years. Our recent peer review occurred in FY 2022-23 for the period July 1, 2016, through
June 30, 2022. The Internal Audit Division was awarded a Certificate of Compliance, the highest
possible rating, from the Association of Local Government Auditors recognizing that the
organization’s internal quality control system was suitably designed and operating effectively to
provide reasonable assurance of compliance with the International Standards for the Professional
Practice of Internal Auditing for assurance and consulting engagements during the audit period. We
have included the report as an attachment to this annual report. Our next peer review will be
performed in FY 2027-28 and will cover July 1, 2022, through June 30, 2027.
Internal Periodic Assessment
Internal assessments are performed to evaluate conformance with the Standards and the
Institute of Internal Auditor’s Code of Ethics. Our next internal assessment will occur in FY 2024-
25.

Ongoing Monitoring
The Internal Audit Division complied with the ongoing monitoring requirement through soliciting
stakeholder feedback, using checklists and taking advantage of automated systems to provide
assurance that processes had been followed. We also monitored project budgets and analyzed
additional performance metrics, including those reported below.
The results of our ongoing monitoring demonstrate that we are perceived as being professional
and knowledgeable, that our work helps management improve business processes and controls,
and that our recommendations are being implemented.
The Internal Audit Division categorizes audit issues into two levels and provides recommendations
for each issue identified. The seriousness of the issue determines the type of department
response required:
Findings – issues which present a serious enough risk to require consideration by
management and a written response to our recommendation(s). The Internal Audit
Division conducts follow-up monitoring on all issues identified as Findings.
Verbal Recommendations – issues which are lower risk and/or a best practice that
could be adopted to improve controls and/or enhance operations. Verbal
Recommendations do not require a written department response and are not
included in the individual engagement report.
All Findings and Verbal Recommendations are discussed with the Department’s management
prior to a report being issued. In most cases the department makes a change to address the issue
before the audit is complete. If not, then findings are followed up on within six to twelve months.
FY 2022-23 Internal Audit Plan Status
The annual audit plan is intentionally created with an ambitious goal of completion and with the
realistic understanding that the Division’s time is flexible and continuously changing to fit the
needs of the both the ACTTC’s office and the County as a whole.
The following table details the status of the audits in the FY 2022-23 audit plan.

Whistleblower Hotline Results
The Internal Audit Division monitors the Whistleblower Hotline, refers reports to related
departments or agencies and conducts follow-up investigations as necessary. In FY 2022-23, the
Whistleblower Hotline received 20 reports, a 23% decrease from the prior year’s 26 reports. 70%
of the reports received were referred to other County departments. One report, which related to
Code Enforcement violations in Nipomo, was partially substantiated. All twenty reports were
received directly through the Whistleblower Hotline. 14 of the 20 reports received were submitted
anonymously.
In addition to matters originating from the Whistleblower Hotline, the Internal Audit Division also provided
assistance with the investigation of an internal report alleging the misappropriation of County funds by a
County employee. This work is ongoing and directly relates to audits underway from the FY 2022-23 and
FY 2023-24 audit plans.
The FY 2022-23 reports received were related to the following categories:

Risk Assessment
The risk assessment is a systematic process used to evaluate, identify, and prioritize potential
audits based on the level of risk to the County. The audit universe, a range of auditable
components is reviewed and updated. An excerpt of the County’s audit universe is included in the
illustration below. Risk is defined as the possibility of an event occurring that will have a financial
or operational impact on the achievement of the County’s objectives and is measured in terms of
impact and likelihood. The assessment identifies exposures that would disrupt the organization’s
operations, interfere with County and departmental goals and business objectives, and serve as
obstacles in the compliance of local and federal governances.
Stakeholder Input
Development of the plan allows for input from the Board of Supervisors, the County
Administrator, departments, and other public stakeholders. At least annually, input is requested
from the Board of Supervisors, the County Administrator, and departments.

Dear Mr. Hamilton,
We have completed a peer review of the County of San Luis Obispo's Internal Audit Division for
the period July 1, 2016 through June 30, 2022. In conducting our review, we followed the
standards and guidelines contained in the Peer Review Guide for Assessing Conformance with
International Standards for the Professional Practice of Internal Auditing by the Association of
Local Government Auditors (ALGA).
We reviewed the internal quality control system of your audit organization and conducted tests
in order to determine if your internal quality control system operated to provide reasonable
assurance of conformance with the International Standards for the Professional Practice of
Internal Auditing (the Standards) issued by the Institute of Internal Auditors as part of their
Professional Practices Framework. Due to variances in individual performance and judgment,
conformance does not imply adherence to standards in every case, but does imply adherence in
most situations.
Based on the results of our review, it is our opinion that the County of San Luis Obispo's Internal
Audit Division internal quality control system was suitably designed and operating effectively to
provide reasonable assurance of conformance with the Standards for assurance and consulting
engagements during the period July 1, 2016 through June 30, 2022.
