Free ISO-9001-Lead-Auditor Practice Test Questions 2026

Explanation:
Understanding Clause 7.1.5.2 – Measurement Traceability:ISO 9001:2015 requires organizations to ensure that measuring equipment (e.g., spectrometers) is calibrated and traceable to recognized standards. The failure to maintain calibration within valid dates directly violates this clause and raises concerns about the reliability of the measurement results.
Root Cause of the Nonconformity:The organization failed to plan for the possibility that the calibration service provider (X-TECH) might become unavailable, leading to expired calibration. This indicates inadequate risk-based thinking, which is required under Clause 6.1 of ISO 9001:2015.

Explanation: According to ISO 9001:2015, clause 4.3, the organization is required to determine the scope of its quality management system (QMS) by considering the external and internal issues referred to in clause 4.1. Clause 4.1 requires the organization to determine the external and internal issues that are relevant to its purpose and strategic direction, and that affect its ability to achieve the intended results of its QMS. These issues can include positive and negative factors or conditions for consideration, such as legal, technological, competitive, market, cultural, social, and economic environments, whether international, national, regional, or local. The organization is also required to monitor and review these issues.
Therefore, the correct answer is C, as external issues of the organization’s context are one of the factors that must be considered when determining the scope of the QMS. The other options are either not directly related to the scope of the QMS, or are not explicitly mentioned in clause 4.3.

Explanation: Top management is responsible for establishing, implementing, and maintaining the quality policy. The quality policy provides a framework for setting quality objectives and must be compatible with the context of the organization and support its strategic direction. It should also provide a commitment to satisfy applicable requirements and to continuous improvement.

Explanation:
In the context of a third-party certification audit, match the roles with the following responsibilities:
Responsibilities:
Conduct the audit to the assigned area.= Auditors
Assist the auditors in identifying personnel to participate in the audit.= Guide
Assign each team member’s responsibility for the audit.= Audit team leader
Respond to questions and provide evidence to the auditor.= Auditee
According to ISO 19011:2018, clause 3, the definitions of the roles are as follows1:
Auditors: persons with the competence to conduct an audit
Guide: person appointed by the auditee to assist the audit team
Auditee: organization being audited
Audit team leader: member of an audit team appointed to manage the audit or an audit team
Therefore, the roles can be matched to the responsibilities based on these definitions and the description of the audit process in clause 6 of the standard1.

Explanation: The auditor could raise the following nonconformities to ISO 9001 based on the scenario: •Option A: 10.3 - The organisation did not continuously improve. Reject rates were unchanged. This option is correct because ISO 9001:2015 clause 10.3 requires the organization to improve the suitability, adequacy and effectiveness of the quality management system. The organization did not demonstrate any improvement in reducing the reject rate of the finished product, which was a stated objective of top management.
The corrective action taken by the organization was not effective in addressing the root cause of the problem and preventing its recurrence.
•Option B: 7.1.4 - The factory environment is not suitably maintained to prevent dirty products. This option is correct because ISO 9001:2015 clause 7.1.4 requires the organization to determine, provide and maintain the environment necessary for the operation of its processes and to achieve conformity of products and services. The organization did not ensure that the factory floor was clean and dry, which affected the quality of the products and increased the risk of nonconformity.
•Option C: 7.1.1 - The organization failed to provide the required resources to prevent nonconforming products. This option is correct because ISO 9001:2015 clause 7.1.1 requires the organization to determine and provide the resources needed for the establishment, implementation, maintenance and continual improvement of the quality management system. The organization did not provide adequate collection baskets for the products ejecting from the moulding machines, which resulted in products falling onto the factory floor and becoming nonconforming.
The following options are not correct:
•Option D: 9.2.2 - Report IA202 contained a poorly worded nonconformity (NC 3). This option is not correct because ISO 9001:2015 clause 9.2.2 does not specify the requirements for the wording of nonconformities in internal audit reports. The nonconformity (NC 3) stated by the internal auditor was clear and relevant to the audit criteria and audit evidence. The issue is not with the report, but with the corrective action taken by the organization.
•Option E: 8.6 - Dirty products were released to the customer. This option is not correct because ISO 9001:2015 clause 8.6 requires the organization to implement planned arrangements, at appropriate stages, to verify that the product and service requirements have been met. The scenario does not indicate that the dirty products were released to the customer, but that they were recalled and repaired then returned to the customers. The issue is not with the release, but with the production process and the environment.
•Option F: 7.3 - Staff were not aware that products were falling onto the factory floor. This option is not correct because ISO 9001:2015 clause 7.3 requires the organization to ensure that the persons doing work under its control are aware of the quality policy, relevant quality objectives, their contribution to the effectiveness of the quality management system, and the implications of not conforming with the quality management system requirements. The scenario does not indicate that the staff were not aware of these aspects, but that the management did not provide adequate resources and environment for the staff to perform their work. The issue is not with the awareness, but with the management responsibility and resource provision.
•Option G: 10.2.1 - Conduct of an investigation was not sufficient to understand the cause of the nonconformity. This option is not correct because ISO 9001:2015 clause 10.2.1 requires the organization to react to the nonconformity and, as applicable, take action to control and correct it and deal with the consequences. The scenario indicates that the Quality Manager conducted an investigation into the reject rates and identified the cause of the nonconformity. The issue is not with the investigation, but with the corrective action taken by the management.
•Option H: 8.5.1 - Production operations were not properly controlled to avoid reject products. This option is not correct because ISO 9001:2015 clause 8.5.1 requires the organization to implement production and service provision under controlled conditions.
The scenario indicates that the production operations were controlled by the moulding machines, which ejected the products into the collection baskets. The issue is not with the production operations, but with the size of the collection baskets and the condition of the factory floor.

Explanation: According to the ISO 9001:2015 standard, clause 8.7 requires that an organization identify and control any nonconforming outputs that do not conform to the requirements of the customer or other relevant requirements. Nonconforming outputs are any outputs from the process, product or service that do not meet the specified quality criteria. Nonconforming outputs must be dealt with in one or more of the following ways:

Correction of the nonconformity Segregation, containment, return or suspension of provision of products and services Informing the customer Authorisation for acceptance under concession
The organization must also retain documented information on the description of the nonconformity, the actions taken, any concessions obtained, and the identification of the authority deciding the action to resolve the nonconformity.
In this scenario, you have interviewed a line supervisor who is responsible for managing a manual picking line where operators are removing contaminant materials from incoming products. The supervisor has explained that these plastic items are rejected at this stage because they do not meet their processing standards and they can damage their machinery and compromise their quality standards. The supervisor has also mentioned that some of these rejected items are melted down in another process later on and some are disposed of as waste products that cannot be recycled.

Based on this information, you can investigate further by taking two actions:

A. Check the process for handling nonconforming items: You can verify whether there is a documented procedure for identifying, segregating, containing, returning or suspending provision of nonconforming items at this stage. You can also check whether there is a system for informing customers about any nonconforming items that may affect their satisfaction or expectations.
D. Determine what happens to the waste products: You can verify whether there is a documented procedure for disposing of waste products that cannot be recycled as per environmental regulations and customer requirements.
These two actions would help you to determine whether there are any nonconforming outputs at this stage and how they are controlled by the organization.

Explanation: A first-party audit is an internal audit conducted by auditors who are employed by the organization being audited but who have no vested interest in the audit results of the area being audited1. The purpose of a first-party audit is to assess the conformity of the organization’s quality management system to the requirements of ISO 9001 and to identify opportunities for improvement2. Therefore, the two auditors who would not participate in a first-party audit are:
•A. An auditor employed by an external consultancy organization: This auditor is not employed by the organization being audited, and therefore does not qualify as a first-party auditor. This auditor may be hired to conduct a second-party audit (if the external consultancy organization is a customer or supplier of the organization being audited) or a third-party audit (if the external consultancy organization is a certification body or registrar). •F. An auditor from a customer: This auditor is not employed by the organization being audited, and therefore does not qualify as a first-party auditor. This auditor may be hired to conduct a second-party audit, as a customer is an interested party that has specific requirements for the organization being audited.
The other options are not correct, as they could participate in a first-party audit, as long as they are employed by the organization being audited and have no vested interest in the audit results of the area being audited:
•B. An auditor from an interested party: This auditor could be a first-party auditor, as long as the interested party is within the organization being audited. For example, an auditor from the finance department could audit the production department, as long as they are not involved in the production process or affected by its outcomes.
•C. An auditor trained in-house: This auditor could be a first-party auditor, as long as they are employed by the organization being audited and have no vested interest in the audit results of the area being audited. The source of the auditor’s training is not relevant for determining the type of audit, as long as the auditor is competent and qualified to perform the audit.
•D. An auditor trained in the IRCA scheme: This auditor could be a first-party auditor, as long as they are employed by the organization being audited and have no vested interest in the audit results of the area being audited. The IRCA scheme is a professional certification scheme for auditors of management systems, which provides recognition of the auditor’s competence and credibility3. However, being trained in the IRCA scheme does not determine the type of audit, as long as the auditor is competent and qualified to perform the audit.
•E. An auditor certified by IRCA: This auditor could be a first-party auditor, as long as they are employed by the organization being audited and have no vested interest in the audit results of the area being audited. Being certified by IRCA means that the auditor has met the requirements of the IRCA scheme and has demonstrated their competence and credibility as an auditor of management systems3. However, being certified by IRCA does not determine the type of audit, as long as the auditor is competent and qualified to perform the audit.

Explanation:
According to ISO 19011:2018, clause 6.3.2, the audit plan is a document that provides the basis for agreement regarding the conduct of the audit. The audit plan should include the following information1:
•the audit objectives, scope and criteria
•the audit team members and their roles and responsibilities
•the audit schedule, including the date, time and location of each audit activity
•the expected time and duration of meetings and interviews
•the allocation of appropriate resources to critical areas of the audit
•the identification of the audit client and the auditee
•the identification of the guides and observers, if any
•the documents and records to be reviewed before and during the audit
•the audit methods and tools to be used
•the audit language and terminology
•the audit report content, format, distribution and expected completion date
•the risk to achieving audit objectives and the contingency plan, if any
Therefore, the issue which is not expected to be included in the audit plan is C, expectations of the organisation’s management. This issue is not relevant to the conduct of the audit, as the audit is based on the audit criteria, not on the management’s expectations. The management’s expectations may be considered during the audit initiation or the audit programme management, but they are not part of the audit plan.

Explanation: According to ISO 19011:2018, clause 3.2, audit criteria are a set of policies, procedures or requirements used as a reference against which objective evidence is compared. Audit criteria are usually selected by the audit client or by agreement between the audit client and the auditee, and they should be appropriate for the audit scope and objectives1. Audit criteria may include, but are not limited to, the following sources2:
•ISO management system standards, such as ISO 9001, ISO 14001, ISO 45001, etc.
•Verbal statements by the general manager or other top management, as long as they are consistent with the documented policies and objectives of the organisation
•Verbal agreements with interested parties, such as customers, suppliers, regulators, etc., as long as they are documented and approved by the relevant authorities
•Health and safety notices, such as posters, signs, labels, etc., that communicate the organisation’s legal obligations, policies, or procedures
•Written agreements with interested parties, such as contracts, orders, specifications, etc., that define the requirements and expectations of the parties involved
•Organisation’s documented information, such as policies, procedures, manuals, records, etc., that describe the organisation’s management system and its processes
•Commitment to follow principles issued by an NGO, such as the United Nations Global Compact, the International Labour Organization, etc., as long as they are relevant to the organisation’s context and objectives
•Environmental aspects register, such as a list of the environmental impacts and risks associated with the organisation’s activities, products, and services
Therefore, the two options that are not potential audit criteria are F and H, as they are not reliable or verifiable sources of information, and they may not reflect the actual performance or conformity of the organisation’s management system. Commercial advertisements and claims made on the organisation’s website are forms of marketing communication that may be exaggerated, misleading, or inaccurate, and they are not subject to the same level of scrutiny or approval as the other sources of audit criteria.
