The ISO 42001 Lead Implementer exam on the AI Training Skool route has 60 scenario-based questions with a 70% pass mark, and the issuer lists a 90-minute time limit. Practice that matches it means scenario questions tied to the clauses of ISO/IEC 42001:2023, and the 25 questions below are built that way.
Every item is original, written by AI Training Skool for self-testing. None is a real exam question, and none is copied or adapted from an exam, a dump site or another practice product. Each one gives the correct answer, why it is right, why each wrong option is wrong, the clause it tests and the record an auditor would ask to see.
How does this mock test compare with the real Lead Implementer exam?
The mock test copies the real exam’s format, one best answer to a workplace scenario, at a smaller size. Use it to find weak clauses before you book, not to predict your score.

The questions cite clause numbers from ISO/IEC 42001:2023 on iso.org, published 18 December 2023, and those numbers were checked against the standard’s official table of contents. Answers paraphrase the requirements and never reproduce the standard’s text.
Context and leadership questions (clauses 4 and 5)
Context and leadership practice questions test whether you can lay the AIMS foundations: roles toward each AI system, relevant issues, a defensible scope, an AI policy and clear authority (clauses 4.1 to 5.3).
1. Which role does an organization record for an AI system it buys and configures?
A US insurer buys a claims triage model from a vendor and configures it inside its own claims workflow. The insurer does not train the model. While setting up the AIMS, what must the insurer determine about this system under clause 4.1?
- A. Its role or roles with respect to the system, such as AI customer or user, recorded against the system’s register entry
- B. Nothing, because clause 4.1 applies only to organizations that develop AI
- C. The vendor’s certification status, which decides whether the system is in scope
- D. Which Annex A controls to exclude, because the insurer is not a developer
Answer: A. Clause 4.1 requires the organization to determine its roles with respect to the AI systems it develops, provides or uses. ISO/IEC 22989:2022 describes those roles.
Why the other options are wrong:
- B. The standard applies to any organization that provides or uses products or services that use AI systems, not only to developers (clause 1).
- C. A vendor’s certificate does not set your scope. Scope is decided under clause 4.3.
- D. Control exclusions come out of risk treatment in clause 6.1.3, not from the role alone.
Clause tested: 4.1. Record involved: AI system register (role per system).
2. What does clause 4.1 expect about climate change?
A gap review of the context record finds a list of internal and external issues but no mention of climate change. The company runs a small inference workload in the cloud. What should the Lead Implementer do?
- A. Leave it out, because climate change has nothing to do with AI governance
- B. Add a climate control to the Statement of Applicability
- C. Record a determination of whether climate change is a relevant issue, with the reason, even if the answer is no
- D. Raise a major nonconformity against top management
Answer: C. Clause 4.1 requires the organization to determine whether climate change is a relevant issue. A dated, reasoned decision is the evidence, whatever the outcome.
Why the other options are wrong:
- A. The clause asks for the determination. Skipping it leaves a gap even if climate change turns out not to matter.
- B. Nothing requires a climate control. The requirement is a determination in the context record.
- D. Grading nonconformities is the auditor’s job, and a missing determination is fixed by making it.
Clause tested: 4.1. Record involved: Context record (internal and external issues).
3. How do you make a partial AIMS scope defensible?
A SaaS company wants its AIMS to cover its customer-facing chatbot and to leave its internal resume screening tool out for now. What makes that scope defensible to an auditor?
- A. Nothing, because the scope must cover every AI system the company uses
- B. Approval of the scope by the certification body before implementation starts
- C. A note that resume screening tools are low risk, so leaving them out needs no further reason
- D. A documented scope with clear boundaries, decided after considering the clause 4.1 issues and the clause 4.2 interested party requirements
Answer: D. Clause 4.3 lets the organization set the boundaries and applicability of its AIMS, provided the scope is documented and takes the issues from 4.1 and the requirements from 4.2 into account.
Why the other options are wrong:
- A. The organization decides the boundaries. A partial scope is allowed if it is reasoned and documented.
- B. The organization determines its scope. A certification body audits it later; it does not approve it up front.
- C. Hiring tools affect people’s job prospects, so calling one low risk without an assessment is a weak basis for a scope decision.
Clause tested: 4.3. Record involved: AIMS scope statement.
4. Who must establish the AI policy?
The compliance team writes an AI policy, posts it on the intranet and emails all staff. The policy commits to meeting applicable requirements and to continual improvement. What is still missing for clause 5.2?
- A. A list of every AI system the company runs
- B. Evidence that top management established the policy
- C. Approval of the policy by the certification body
- D. Technical specifications for each model in use
Answer: B. Clause 5.2 places the AI policy with top management, and the standard defines a policy as direction formally expressed by top management (3.5). An approval record from top management closes the gap.
Why the other options are wrong:
- A. The system list belongs in the register. The policy sets direction and a framework for AI objectives.
- C. Certification bodies audit policies. They do not approve them.
- D. Model specifications are system documentation, not policy content.
Clause tested: 5.2. Record involved: AI policy with top management approval.
5. Which clause applies when a role has responsibility but no authority?
The AI product lead is named “responsible for AI governance” but has no authority to pause a deployment, and nobody outside her team knows about the assignment. An internal auditor raises it. Which requirement is involved?
- A. Clause 5.3, because top management must assign and communicate responsibilities and authorities for relevant roles
- B. Clause 7.2, because she needs more training
- C. Clause 9.3, because the item can only be handled at management review
- D. Clause 10.1, because it is a continual improvement matter
Answer: A. Clause 5.3 requires top management to assign responsibilities and authorities for relevant roles and to communicate them. A responsibility with no authority, and no communication, fails both parts.
Why the other options are wrong:
- B. Competence is about ability. The problem here is authority and communication.
- C. Management review can discuss it, but the gap sits in how the role was assigned.
- D. Continual improvement is the general duty. The specific requirement is clause 5.3.
Clause tested: 5.3. Record involved: Roles, responsibilities and authorities record (for example a RACI chart).
AI risk, impact assessment and objectives questions (clause 6)
Clause 6 practice questions test planning: risk criteria, risk assessment, risk treatment and the Statement of Applicability, the AI system impact assessment and AI objectives. Planning sets the processes up; clause 8 later requires running them.
6. Why do two assessors score the same AI risk differently?
Two assessors rate the same model drift risk, one as high and one as low. Neither broke the method, because the method has no defined scales or acceptance thresholds. What should exist first?
- A. A risk tool that calculates scores automatically
- B. An average of the two ratings, recorded in the risk register
- C. AI risk criteria that separate acceptable from unacceptable risk, so repeated assessments give consistent, comparable results
- D. An entry for the risk in the Statement of Applicability
Answer: C. Clause 6.1.1 has the organization establish AI risk criteria, and clause 6.1.2 expects a risk assessment process that gives consistent, valid and comparable results when it is repeated.
Why the other options are wrong:
- A. A tool applies whatever criteria you give it. Without criteria, it automates the disagreement.
- B. Averaging hides the problem, and the next pair of assessors will disagree again.
- D. The SoA records control decisions, not how risk is scored.
Clause tested: 6.1.1 and 6.1.2. Record involved: AI risk assessment method and risk criteria.
7. Whose consequences does an AI risk assessment cover?
The AI risk register scores only financial and reputational consequences to the company. One in-scope model screens thousands of job applicants a year. What is the gap?
- A. None, because risk is always measured against the organization
- B. Consequences to individuals and societies must also be assessed, using the impact assessment results where they apply
- C. The risk register should be replaced by the impact assessment
- D. Only possible regulatory penalties need to be added
Answer: B. Clause 6.1.2 asks for the potential consequences to the organization, to individuals and to societies to be assessed, taking the AI system impact assessment results into account where applicable.
Why the other options are wrong:
- A. Clause 6.1.2 reaches beyond the organization: consequences to individuals and societies are part of the assessment.
- C. The two records do different jobs, one for risk and one for impacts on people, and both are required.
- D. Penalties are one consequence to the organization. Harm to applicants is the missing part.
Clause tested: 6.1.2. Record involved: AI risk register.
8. What must happen after you choose controls from your own framework?
The team picks risk treatment controls from its existing security framework, then drafts a Statement of Applicability. What else does clause 6.1.3 require?
- A. Implementing every Annex A control regardless of risk
- B. Listing only the controls that are implemented
- C. Replacing Annex A entirely with the in-house framework
- D. Comparing the chosen controls with Annex A to check nothing necessary was left out, then justifying each inclusion and exclusion in the SoA
Answer: D. Clause 6.1.3 has the organization compare its controls with Annex A to verify no necessary control is missing. The SoA then documents the necessary controls and the justification for including or excluding them (3.26).
Why the other options are wrong:
- A. The standard’s own note says an organization may not need every Annex A control.
- B. Exclusions and their justifications belong in the SoA too.
- C. Your own controls can be added, but the comparison with Annex A is still required.
Clause tested: 6.1.3. Record involved: Statement of Applicability and risk treatment plan.
9. Does a DPIA cover the AI system impact assessment?
Privacy counsel says the existing data protection impact assessment (DPIA) for a new resume screening model already satisfies ISO/IEC 42001. What is the best response?
- A. Agree, because a DPIA covers personal data and that is all an impact assessment covers
- B. Agree, provided the DPIA is less than a year old
- C. Use the DPIA as an input, but assess the AI system’s impacts on individuals, groups and societies, such as unfair outcomes for groups of applicants
- D. Skip both, because impact assessments are optional
Answer: C. The standard defines the AI system impact assessment as a documented process that identifies, evaluates and addresses impacts on individuals, groups of individuals and societies (3.24). A DPIA looks at personal data processing, so it is an input, not a substitute.
Why the other options are wrong:
- A. Impacts on groups and on society reach beyond personal data.
- B. The age of the DPIA is not the issue. Its scope is.
- D. Clause 6.1.4 makes the AI system impact assessment a requirement.
Clause tested: 6.1.4. Record involved: AI system impact assessment.
10. What turns a slogan into an AI objective?
The draft AI objective reads “Be responsible with AI.” What does clause 6.2 expect instead?
- A. Objectives that are measurable where practicable and monitored, with a plan for what will be done, the resources, who is responsible, when it will be done and how results are evaluated
- B. A longer statement of values
- C. Objectives copied from Annex C without change
- D. No change, because AI objectives are optional
Answer: A. Clause 6.2 expects AI objectives that are consistent with the AI policy, measurable where practicable and monitored, with a plan to achieve them.
Why the other options are wrong:
- B. More words do not make an objective measurable or planned.
- C. Annex C is informative and lists potential objectives. The organization still sets and plans its own.
- D. Clause 6.2 is a requirement.
Clause tested: 6.2. Record involved: AI objectives and plans to achieve them.
Support and operation questions (clauses 7 and 8)
Support and operation practice questions test whether the AIMS works day to day: competence, awareness, document control, and performing risk assessment, risk treatment and impact assessment when systems change (clauses 7.2 to 8.4).
11. What competence evidence will an auditor ask for?
Data scientists run the AI system impact assessments. None has recorded training or experience in impact assessment. The auditor asks how the organization knows they are competent. What does clause 7.2 require?
- A. A signed statement from each person saying they are competent
- B. Determining the competence the work needs, making sure people have it through education, training or experience, acting on gaps, and keeping documented evidence
- C. An external certificate for every person
- D. Nothing, because data scientists are competent by job title
Answer: B. Clause 7.2 has the organization determine the necessary competence, ensure people have it, take action where needed and evaluate that action, and retain documented information as evidence of competence.
Why the other options are wrong:
- A. A self-declaration is not evidence of competence.
- C. Certificates are one way to show competence. The standard does not require them.
- D. A job title does not show competence in a specific task such as impact assessment.
Clause tested: 7.2. Record involved: Competence records.
12. Which requirement fails when staff have never heard of the AI policy?
Customer support agents use an approved generative AI drafting tool every day. In interviews, none of them know an AI policy exists or what happens if they paste customer data into the tool. Which requirement is not met?
- A. Clause 7.1, resources
- B. Clause 9.1, monitoring and measurement
- C. Clause 4.2, interested parties
- D. Clause 7.3, awareness of the AI policy, of their contribution and of the implications of not conforming
Answer: D. Clause 7.3 requires people doing work under the organization’s control to be aware of the AI policy, their contribution to the AIMS and the implications of not conforming.
Why the other options are wrong:
- A. The tool and the staff exist. The gap is what the staff know.
- B. Monitoring might reveal the gap, but the requirement that failed is awareness.
- C. Clause 4.2 is about the needs of interested parties, not staff awareness of the policy.
Clause tested: 7.3. Record involved: Awareness and policy acknowledgment records.
13. Which requirement breaks when an approved record is edited with no version history?
An approved impact assessment lives on one analyst’s personal drive. It was edited after sign-off, and there is no version history. Which requirement does this break?
- A. Clause 7.5.3, control of documented information, which covers availability, protection and version control
- B. Clause 6.2, AI objectives
- C. Clause 5.1, leadership and commitment
- D. Clause 8.1, operational planning and control
Answer: A. Clause 7.5.3 requires documented information to be available where needed, protected and under version control. An approved record that changed with no history fails all three.
Why the other options are wrong:
- B. Objectives have nothing to do with how a record is stored.
- C. Leadership commitment is too general. The specific requirement is document control.
- D. Operational control is about running processes as planned. Record control sits in 7.5.3.
Clause tested: 7.5.3. Record involved: Approved AI system impact assessment under version control.
14. What must happen when a vendor swaps the underlying model?
The risk assessment for a vendor-supplied chatbot was done in January. In June the vendor replaces the underlying model with a new version. Nobody reassesses. Which clause most directly requires action?
- A. Clause 6.1.2, because the risk assessment process is defined there
- B. Clause 9.3, because only management review can trigger a reassessment
- C. Clause 8.2, because AI risk assessments are performed at planned intervals and when significant changes are proposed or occur
- D. Clause 10.2, because the vendor’s model change is itself a nonconformity
Answer: C. Clause 8.2 requires AI risk assessments at planned intervals and when significant changes are proposed or occur. A model swap is a significant change.
Why the other options are wrong:
- A. Clause 6.1.2 sets up the process. Clause 8.2 is the requirement to run it in operation, and that is what was missed.
- B. Management review is not the only trigger. A significant change is a trigger by itself.
- D. The vendor’s change is not a nonconformity. Failing to reassess could become one.
Clause tested: 8.2. Record involved: AI risk register (reassessment entry).
15. Which clause covers a risk treatment that never happened?
The risk treatment plan says a person reviews every declined claim before the decision is sent. Six months later, sampling shows no reviews were done. Which clause is not met?
- A. Clause 6.1.4, AI system impact assessment
- B. Clause 7.4, communication
- C. Clause 4.4, AI management system
- D. Clause 8.3, implementing the AI risk treatment plan
Answer: D. Clause 8.3 requires the organization to implement the AI risk treatment plan. A planned human review that never ran is a treatment that was never implemented.
Why the other options are wrong:
- A. The impact assessment identifies harm. The failure here is carrying out the agreed treatment.
- B. Poor communication may be a cause, but the requirement that failed is implementing the plan.
- C. Clause 4.4 is the general duty to run the AIMS. Clause 8.3 is the specific one.
Clause tested: 8.3. Record involved: Risk treatment plan and implementation evidence.
16. What happens when a model is extended to a new population?
A credit model is retrained on new data and offered to applicants in a second state. Its AI system impact assessment is 18 months old. What should happen?
- A. Perform the impact assessment again, because a significant change has occurred, and keep the results
- B. Nothing until the next scheduled annual review
- C. Update only the risk register
- D. Ask the certification body for an exemption
Answer: A. Clause 8.4 requires AI system impact assessments at planned intervals and when significant changes are proposed or occur, with the results retained as documented information.
Why the other options are wrong:
- B. A significant change is a trigger in its own right. You do not wait for the calendar.
- C. Risk to the organization and impact on people are separate records, and both need review here.
- D. Certification bodies do not grant exemptions from requirements.
Clause tested: 8.4. Record involved: AI system impact assessment (reassessment).
Performance evaluation and improvement questions (clauses 9 and 10)
Performance evaluation and improvement practice questions test the checking side of the AIMS: monitoring, the internal audit program, management review and corrective action (clauses 9.1 to 10.2).
17. What does clause 9.1 expect beyond a dashboard?
A dashboard shows model accuracy every week, but nobody decided what to monitor, by what method, or when results are analyzed and evaluated. What does clause 9.1 expect?
- A. Nothing more, because a weekly dashboard meets the clause by itself
- B. That internal audit does all monitoring
- C. That the organization decides what to monitor and measure, the methods, when to monitor and when to analyze and evaluate, and keeps evidence of the results
- D. That only financial metrics are monitored
Answer: C. Clause 9.1 requires the organization to determine what needs monitoring and measuring, the methods, and when monitoring, analysis and evaluation happen, and to keep documented evidence of the results.
Why the other options are wrong:
- A. Data without decided methods and evaluation does not meet 9.1.
- B. Internal audit is a separate requirement (9.2). Process owners run monitoring.
- D. Performance in this standard covers results of AI systems and of the AIMS itself (3.11).
Clause tested: 9.1. Record involved: Monitoring and measurement results.
18. Can the implementer audit her own work?
The Lead Implementer who wrote the Statement of Applicability offers to audit the risk treatment process herself to save time. What should the organization do?
- A. Choose an auditor who did not do the work, from inside the company or from an external party acting for it, so the audit is objective and impartial
- B. Accept, because she knows the process best
- C. Leave that process out of this year’s audit
- D. Ask the certification body to carry out the internal audit
Answer: A. Clause 9.2.2 requires auditors to be selected, and audits run, so that the audit process is objective and impartial. The standard’s definition of audit allows an internal audit to be done by an external party on the organization’s behalf (3.18).
Why the other options are wrong:
- B. Knowing the process is the reason she should not audit it: she would be judging her own decisions.
- C. The program has to cover the AIMS. Dropping a process to avoid a conflict creates a gap.
- D. Certification bodies working under ISO/IEC 17021-1 do not provide internal audits to the clients they certify.
Clause tested: 9.2.2. Record involved: Internal audit program and audit report.
19. How often does ISO 42001 require internal audits?
While planning the first internal audit program, the CFO asks how often ISO/IEC 42001 requires internal audits. What is the correct answer?
- A. Every quarter
- B. Once a year, in the month before the certification audit
- C. Only once, before the first certification audit
- D. At planned intervals that the organization sets, considering the importance of the processes and the results of previous audits
Answer: D. Clause 9.2 requires internal audits at planned intervals and sets no fixed frequency. Under 9.2.2, the program sets frequency, methods, responsibilities, planning and reporting, and considers process importance and earlier audit results.
Why the other options are wrong:
- A. Quarterly is a common choice, not a requirement.
- B. The standard does not tie internal audits to the certification calendar.
- C. Internal audits continue for as long as the AIMS runs.
Clause tested: 9.2.2. Record involved: Internal audit program.
20. What is missing from management review minutes with no decisions?
Management review minutes list who attended and attach a slide deck, but record no decisions. What is missing?
- A. A longer slide deck
- B. Signatures from every attendee
- C. Decisions on continual improvement opportunities and any needed changes to the AIMS, kept as documented evidence
- D. A review of the minutes by the certification body
Answer: C. Clause 9.3.3 says the results of management review include decisions on continual improvement opportunities and any need for changes to the AIMS, with documented information kept as evidence of those results.
Why the other options are wrong:
- A. A slide deck is an input, not a result.
- B. Attendance is not a decision.
- D. Management review is top management’s own activity.
Clause tested: 9.3. Record involved: Management review minutes and decisions.
21. Can a missing approval date be fixed by backdating it?
An internal audit finds three impact assessments with no recorded approval date. The owner types in approval dates from last spring and closes the item the same day. What should the Lead Implementer require?
- A. Nothing, because the records are now complete
- B. A response to the nonconformity: correct it, find the cause, act on it, check the action worked and keep records, without altering dates after the fact
- C. Deleting the three assessments and starting again
- D. Waiting for the certification body to raise it
Answer: B. Clause 10.2 requires the organization to react to a nonconformity, evaluate the need to remove its cause, implement action, review the action’s effectiveness and retain documented information. Backdated entries make the records false.
Why the other options are wrong:
- A. Inserting old dates corrects nothing and damages the integrity of the records.
- C. Deleting records destroys evidence and does not fix the cause.
- D. Waiting turns a known internal problem into an external one.
Clause tested: 10.2. Record involved: Nonconformity and corrective action log.
Annex A and Statement of Applicability questions
Annex A practice questions test how controls are chosen, excluded and justified. Annex A control numbers are left out on purpose: they cannot be checked against a free official source, so the control themes are named in plain words. For each theme in turn, see the nine Annex A control objectives in ISO 42001.
22. How will an auditor read a supplier control exclusion?
The SoA excludes the Annex A controls on suppliers and third parties with the justification “not applicable”. The company’s main product calls a third-party foundation model through an API. How will an auditor likely read this?
- A. As acceptable, because any exclusion is allowed if it is written down
- B. As acceptable, because supplier controls apply only to manufacturers
- C. As a weak justification: the company relies on an AI supplier, so the exclusion conflicts with its own risk picture
- D. As irrelevant, because auditors do not review the SoA
Answer: C. The SoA must justify each exclusion, and all identified risks and the controls that address them must be reflected in it (3.26). A company that depends on an AI supplier cannot credibly call supplier controls not applicable.
Why the other options are wrong:
- A. A justification has to be true and tied to a risk. Being written down is not enough.
- B. Supplier controls apply to any organization that relies on third-party AI.
- D. The SoA is a required record under clause 6.1.3, so auditors review it.
Clause tested: 6.1.3 and the Annex A supplier and third-party controls. Record involved: Statement of Applicability.
23. What does data quality mean in ISO 42001?
A lender’s data team says its training data is high quality because it has no missing values. The model will now score applicants in a new region. How should data quality be judged?
- A. Against documented data requirements for the specific use, including whether the data represents the new applicant population
- B. By completeness alone
- C. By the size of the dataset
- D. By the vendor’s written assurance
Answer: A. The standard defines data quality as data meeting the organization’s data requirements for a specific context (3.25). Annex A has a control objective area on data for AI systems, so data requirements, provenance and checks are recorded for each use.
Why the other options are wrong:
- B. Having no missing values says nothing about fitness for a new population.
- C. Volume does not show fitness for purpose.
- D. A vendor statement is an input. Your own data requirements decide quality.
Clause tested: 3.25 and the Annex A data controls. Record involved: Data requirements and data quality record.
24. Can you exclude internal audit the way you exclude a control?
A manager argues that the company can skip the clause 9.2 internal audit this year because, like an Annex A control, it can be excluded with a written justification. What is the correct position?
- A. Correct, if the justification is recorded in the SoA
- B. Correct, if top management signs it off
- C. Incorrect, and Annex A controls cannot be excluded either
- D. Incorrect: clause 9.2 is a requirement of the standard, and only controls, whether from Annex A or added by the organization, go through the inclusion or exclusion decision recorded in the SoA
Answer: D. Clauses 4 to 10 hold the requirements. The SoA records decisions about controls, including any the organization adds beyond Annex A (3.26), and internal audit is a requirement, not a control to be selected.
Why the other options are wrong:
- A. The SoA covers controls, not clause requirements.
- B. Management sign-off cannot remove a requirement.
- C. Annex A controls can be excluded with a justification (3.26, note 1).
Clause tested: 9.2 and 6.1.3. Record involved: Internal audit program and Statement of Applicability.
25. Is Annex B normative or informative?
A team plans to treat Annex B, the implementation guidance for the Annex A controls, as optional reading because “guidance annexes are always informative”. What does the official table of contents of ISO/IEC 42001:2023 say?
- A. Annex B is informative, like Annex C and Annex D
- B. Annex B is normative, as is Annex A, while Annex C and Annex D are informative
- C. All four annexes are informative
- D. Annex B was removed by an amendment
Answer: B. The official table of contents labels Annex A and Annex B as normative and Annex C and Annex D as informative. Use Annex B when you implement the controls you selected.
Why the other options are wrong:
- A. Many published summaries say this, but the official contents list labels Annex B normative.
- C. Annex A is normative and holds the reference controls.
- D. iso.org lists no amendment to ISO/IEC 42001:2023 as of October 2026.
Clause tested: Annexes A to D. Record involved: Statement of Applicability and control implementation evidence.

How to score your ISO 42001 practice test
Count one point per correct answer. A score of 18 or more out of 25 (72%) clears the 70% line the real exam uses, and anything lower means at least one clause group needs work before you book.
| Score out of 25 | Percent | What it suggests | Next step |
| 23 to 25 | 92% to 100% | Clause logic is solid | Sit a full-length 60-question practice exam under timed conditions |
| 18 to 22 | 72% to 88% | Above the pass line with gaps | Fix the clause group with the most misses, then retest |
| 13 to 17 | 52% to 68% | Below the 70% line | Reread the clauses behind each miss and redo the set in a week |
| 0 to 12 | 48% or less | Foundations are missing | Study clauses 4 to 10 in order before more practice questions |

Two cautions. A score on 25 items you have seen before rises with repetition, so treat your first attempt as the honest one. And a high score here does not predict a pass: the real exam is longer, timed and proctored.
If you land in the lowest band, check ISO 42001 Lead Implementer requirements by professional background to see what to brush up on before a course.
What to do with your practice test results
Your missed practice questions show which clauses to study next. Sort them by group, because each group points to a different kind of gap.
- Misses in clauses 4 and 5: you know the terms but not who decides what. Write out, for each record, who drafts it and who approves it.
- Misses in clause 6: you are mixing up risk to the organization with impact on people, or the SoA with the risk register. Keep the two pairs apart.
- Misses in clauses 7 and 8: you are treating planning as a one-off. Learn the change triggers in 8.2 and 8.4.
- Misses in clauses 9 and 10: you know what audits and reviews are, but not what evidence they must leave.
- Misses in Annex A: practice writing an exclusion justification that ties to a named risk.
When you review a wrong answer, do not memorize the letter. Ask three questions instead: which clause applies, which record proves it, and who signs that record. That routine works on questions you have never seen.
Then put the weak clauses into your calendar, using a realistic ISO 42001 Lead Implementer study schedule to fit review into a normal week.
If you want full-length practice in the real format before you book, an ISO 42001 Lead Implementer course with an exam simulator and full-length practice exams is the next step. AI Training Skool’s course is US$795, covers 32 CPD hours across 16 modules, and includes two attempts at the proctored exam.
Frequently asked questions
Are ISO 42001 exam dumps worth using?
No. Exam dumps claim to be real questions copied from live exams. Using leaked exam content can breach the rules you accept when you book, which can put the certificate at risk. Dumps also give letters without reasons, so you memorize answers instead of learning to apply clauses to a new scenario, which is what the 60 scenario-based questions test.
Is there an ISO 42001 Lead Implementer practice questions PDF?
AI Training Skool does not publish these 25 questions as a separate PDF. You can print this page or save it as a PDF from your browser for offline study, with every answer and clause citation included. Treat any PDF sold as real ISO 42001 exam questions and answers with suspicion: it is either a dump or practice material with a misleading label.
Is there a free ISO 42001 Lead Implementer mock test?
Yes. This page holds a free 25-question ISO 42001 Lead Implementer mock test that scores itself in your browser and explains every answer with the clause it tests. It is a short sample of the real exam on the AI Training Skool route, which has 60 scenario-based questions, a 70% pass mark and a 90-minute limit the issuer lists.
What practice test score means I am ready to book the exam?
On this 25-question set, 18 correct (72%) is the first score at or above the 70% pass mark the real ISO 42001 Lead Implementer exam uses. Treat a first-attempt score above that line as a sign to move to a full-length, timed 60-question practice exam. Book the real exam when you clear 70% there with room to spare, not when you scrape past it.
Are these the real ISO 42001 exam questions?
No. All 25 questions are original practice items written by AI Training Skool from the clause structure of ISO/IEC 42001:2023. They copy the exam’s format, a scenario with one best answer, but not its content. Real exam items are not public, and nothing on this page is drawn from them or from any dump or practice product.
Do ISO 42001 Lead Auditor practice questions help with the Lead Implementer exam?
Partly. Both credentials draw on ISO/IEC 42001 clauses 4 to 10 and Annex A, so clause knowledge carries over. Lead Auditor questions center on audit method, such as sampling evidence and grading nonconformities. Lead Implementer questions ask what to build and who decides, so practice with implementer scenarios like the 25 above before the exam.
