Audit & Assurance Skills for Evidence-Based Professional Practice
Audit and assurance activities help organisations and stakeholders gain greater confidence in financial information, processes, controls and reported outcomes.
For accounting and finance professionals, effective audit and assurance capability requires more than technical knowledge. It involves understanding risk, evaluating evidence, applying professional scepticism, communicating findings and exercising sound professional judgement.
CIMFA supports the development of practical audit and assurance skills as part of wider professional competence and responsible financial practice.
Understand the Purpose of Audit and Assurance
Audit and assurance work is fundamentally concerned with obtaining and evaluating information in order to support informed conclusions.
Professionals should understand the purpose of an engagement, the information being considered, the risks that may affect it and the evidence needed to support a conclusion.
A clear understanding of purpose helps ensure that professional work remains focused, proportionate and relevant.
Start with the purpose.
What is being assessed?
Clearly identify the subject matter, information or process under consideration.
Why does it matter?
Understand the needs of the intended users and the significance of the information.
What evidence is relevant?
Determine what information can support a reliable professional conclusion.
Develop the Ability to Identify Audit and Assurance Risks
Effective assurance work begins with understanding where significant errors, omissions, inconsistencies or weaknesses could arise.
Professionals should consider the nature of the information, the processes producing it, relevant controls and the circumstances that could affect its reliability.
Understand the Process
Identify how information is created, processed, reviewed and ultimately reported.
Identify Vulnerabilities
Consider where errors, omissions or inappropriate activity could affect the information being assessed.
Consider Significance
Evaluate which issues could have meaningful implications for the engagement or its users.
Prioritise Attention
Focus professional effort on areas where risk and significance justify greater attention.
Learn to Evaluate Evidence With Discipline
Professional conclusions should be supported by appropriate evidence. Developing evidence skills requires professionals to consider relevance, reliability, sufficiency and the circumstances in which information was obtained.
Evidence should not simply be collected. It should be evaluated in relation to the question being addressed and the risks identified.
This disciplined approach strengthens the quality and defensibility of professional conclusions.
Ask whether the evidence really supports the conclusion.
Is it relevant?
Determine whether the evidence addresses the issue being considered.
Is it reliable?
Consider the source, nature and circumstances surrounding the information.
Is it sufficient?
Assess whether enough appropriate evidence has been obtained for the purpose.
Does it make sense together?
Consider whether different pieces of evidence are consistent or require further investigation.
Develop Constructive Professional Scepticism
Professional scepticism involves maintaining an appropriately questioning mindset rather than accepting information without consideration.
It does not mean assuming that information is incorrect. Instead, it requires professionals to remain alert to circumstances that may require additional evidence, explanation or investigation.
A constructive questioning approach can improve the quality of assurance work while maintaining professional respect and objectivity.
Use Analysis to Identify Unexpected Patterns
Analytical thinking can help professionals identify relationships, trends and movements that may require further attention.
Comparing financial and operational information can reveal unexpected changes or relationships that deserve investigation.
Analysis should support professional understanding rather than replace detailed evaluation where additional evidence is required.
Investigate what does not fit.
What changed?
Identify unusual movements, relationships or trends.
Why did it change?
Seek a reasonable explanation supported by appropriate information.
Is the explanation consistent?
Compare the explanation with other available evidence.
Does more work appear necessary?
Use professional judgement to determine whether further investigation is appropriate.
Understand How Controls Influence Assurance Work
Controls form part of many financial and operational processes. Understanding how they are designed and performed can help professionals assess where risks may arise and where further attention may be required.
Professionals should distinguish between a control existing on paper and a control operating effectively in practice.
Control Design
Understand whether a control is appropriately designed to address the relevant risk.
Control Operation
Consider whether the control is actually performed as intended.
Control Evidence
Evaluate whether appropriate evidence demonstrates that relevant control activity occurred.
Control Changes
Recognise when changes in systems, processes or responsibilities may affect control effectiveness.
Create Clear and Useful Professional Documentation
Good documentation provides a clear record of the work performed, evidence considered, professional reasoning and conclusions reached.
Documentation should be sufficiently clear that another appropriately informed professional can understand the work and the basis for the conclusion.
Strong documentation also encourages disciplined thinking because professionals must explain how evidence supports their judgement.
Document the reasoning, not just the activity.
What was considered?
Identify the relevant information, process or risk.
What was found?
Record significant observations and evidence.
What does it mean?
Explain the professional interpretation.
What was concluded?
Clearly connect the evidence and reasoning with the final conclusion.
Communicate Findings Clearly and Objectively
Audit and assurance findings need to be communicated in a way that is accurate, balanced and useful to the intended audience.
Professionals should distinguish between facts, evidence, interpretation and professional conclusions.
Clear reporting can help decision-makers understand significant issues and consider appropriate responses without unnecessary technical complexity.
Maintain Quality Throughout the Engagement
Quality should be considered throughout professional work rather than only at the final review stage.
This means maintaining appropriate planning, evidence, documentation, review and communication while remaining alert to changes that could affect the engagement.
A quality-focused approach helps professionals produce work that is consistent, understandable and appropriately supported.
Quality is built throughout the process.
Plan carefully.
Understand objectives, risks and required work before beginning detailed procedures.
Evaluate continuously.
Remain alert to information that changes the understanding of risk.
Review critically.
Check whether evidence and conclusions remain appropriately connected.
Communicate clearly.
Present significant findings in a useful and objective form.
Protect Objectivity and Professional Integrity
Audit and assurance work depends on professional objectivity and responsible judgement.
Professionals should remain aware of circumstances that could influence their judgement and should approach evidence and conclusions with appropriate independence of thought.
Maintaining professional integrity helps protect confidence in the work performed and the conclusions communicated.
Develop Awareness of Technology in Assurance Work
Financial information is increasingly produced, processed and analysed through digital systems.
Professionals should understand how system-generated information, automated processes, data quality and technology dependencies can influence assurance work.
Digital capability should complement professional judgement rather than replace critical evaluation of information.
Technology changes the evidence environment.
Understand the source.
Know how important information is generated and processed.
Consider data quality.
Remain alert to incomplete, inconsistent or unreliable information.
Understand automation.
Recognise that automated processes depend on appropriate configuration and inputs.
Apply judgement.
Evaluate digital outputs rather than accepting them without professional consideration.
