A judgment sample in auditing refers to a sampling method where an auditor uses their personal experience and professional judgment to select the number and the specific items to examine within a population. This method is grounded in the auditor’s familiarity with the client and aims to ensure the objectivity and thoroughness of the audit.
How Judgment Sampling Works
Auditor’s Experience and Familiarity
Auditors leverage their experience and understanding of a client’s business operations to make informed decisions about the sample. This subjective selection process factors in:
- Risk Assessment: Identifying high-risk areas within the financial statements.
- Materiality: Knowing what items are significant to the overall financial health of the organization.
- Previous Audit Results: Considering findings and anomalies from prior audits.
- Industry Knowledge: Understanding typical issues within the industry the client operates in.
Sample Size and Selection
The auditor determines:
- Number of Items to Examine: Based on the complexity and size of the population.
- Specific Items to Audit: Choosing items that are likely to provide insightful results about the population’s characteristics or areas considered high-risk.
Why Use Judgment Sampling?
Advantages
- Efficiency: Allows auditors to focus on areas most likely to contain errors or fraud.
- Expert Insight: Utilizes the auditor’s experience and expertise, adding a layer of professional skepticism.
- Flexibility: Adapts to the specifics of the client’s operations and business environment.
Disadvantages
- Risk of Bias: Since the selection is subjective, there is a potential for auditor bias.
- Non-replicability: Different auditors may choose different items, leading to variations in audit findings.
- Overlooked Areas: Critical items may be inadvertently omitted from the sample.
Examples
Consider an auditor tasked with auditing a large retailer. Instead of randomly sampling transactions, the auditor may decide to:
- Focus on high-value transactions.
- Audit transactions occurring at year-end.
- Examine transactions related to a specific supplier known for past discrepancies.
Historical Context
Judgment sampling has been a longstanding practice in the field of auditing. While modern auditing standards emphasize the use of statistical sampling techniques to minimize bias and improve reliability, judgment sampling remains a crucial tool, particularly for its effectiveness in identifying areas of concern quickly.
Applicability
When to Use
Judgment sampling is particularly useful:
- In initial risk assessments.
- When dealing with small populations where statistical sampling may not be practical.
- For areas requiring deep, expert analysis rather than broad overview.
Comparisons to Statistical Sampling
- Statistical Sampling: Quantitative, relies on random selection and probability theory to make generalizable conclusions about the population.
- Judgment Sampling: Qualitative, relies on the auditor’s expertise and is tailored to specific audit needs, though less generalizable.
Related Terms
- Sampling Risk: The risk that the auditor’s conclusion based on a sample may differ from the conclusion if the entire population were tested.
- Materiality: A threshold set by auditors to determine the significance of an item or error in the financial statements.
- Professional Skepticism: A mindset auditors maintain to critically assess evidence and remain alert to conditions that may indicate possible fraud or misstatement.
FAQs
Q: Is judgment sampling as reliable as statistical sampling?
A: While judgment sampling leverages the auditor’s expertise, it is subject to bias and lack of replicability, which can make it less reliable than statistical sampling in some cases.
Q: Can auditors use both judgment and statistical sampling?
A: Yes, auditors often use a combination to balance the thoroughness of judgment sampling with the objectivity and precision of statistical sampling.
Q: How do auditors minimize bias in judgment sampling?
A: By adhering to established auditing standards, undergoing peer reviews, and maintaining documentation of audit procedures and rationale for sample selection.

Summary
Judgment sampling remains an integral part of auditing practice due to its efficiency and the nuanced insights it provides. By relying on the auditor’s professional judgment, experience, and knowledge of the client, auditors can target specific areas of concern and achieve thoroughness and objectivity in their audits.
