How does the exam work?
The ISO 27001 Auditor exam is administered online on our secure platform.
To ensure the integrity of the certification (in accordance with ISO/IEC 17024 requirements), a remote proctoring system is in place. You must have a computer equipped with a working webcam, a microphone, and a stable internet connection. The candidate’s identity is verified before the exam begins.
Granting of Certification Status
Your certification depends solely on your exam score.
At LSTI, you can then enhance its value by earning an additional grade, based on your level of experience.
The awarding of this grade is based on a combination of two criteria: your performance on the exam and your hands-on experience.
Performance Levels
In accordance with LSTI certification regulations, the certification you receive attests to a level based on your final score out of 100 points:
- Elementary: Score between 50 and 59.
- Intermediate: Score between 60 and 74.
- Advanced: Score of 75 or higher.Levels of experience
Experience Levels
To recognize your level of field experience, LSTI further distinguishes between three statuses:
- Provisional Auditor: This level is assigned to you if you do not yet have any audit experience.
- Confirmed Auditor: This level is assigned to you when you have at least 20 days of audit experience under the ISO 27001 standard as an auditor.
- Lead Auditor: This level is assigned to you when you have at least 20 days of audit experience under the ISO 27001 standard, including at least 3 full audits in the role of lead auditor, over the past 3 years.
Example of grade calculation
- Exam score of 64/100 + 20 days of audit experience: Confirmed Auditor – Intermediate level.
- Score of 58/100 + Lead Auditor experience: Confirmed Auditor – Elementary Level (since the score is below 75, Lead Auditor status cannot be granted despite the experience).
Your Questions About ISO/IEC 27001 Auditor Certification
-
What proof of experience must be provided to validate ISO/IEC 27001 Auditor or Lead Auditor certification?
When registering for the personnel certification exam, the candidate must submit the DT138 certificate along with official proof of experience provided by a client or employer. LSTI’s regulatory requirements vary depending on the certification status sought:
- For ISO/IEC 27001 Auditor certification: Proof of having conducted at least 20 days of audits against the ISO/IEC 27001 standard over the past three years.
- For ISO/IEC 27001 Lead Auditor certification: Proof of having conducted at least 20 days of audits against the ISO/IEC 27001 standard over the past three years, including at least 3 full audits performed in the role of audit leader, as well as a passing score on the advanced-level written exam.
- Without prior experience: Candidates who have not yet accumulated this field experience may still take the exam; if they pass the written exam, they will be granted temporary Provisional Auditor status.
-
What is the difference between an ISO 27001 Lead Auditor and an ISO 27001 Lead Implementer?
Although they both work within the same framework, a Lead Auditor and a Lead Implementer play diametrically opposed roles within an ISMS.
The Lead Implementer is the architect who designs, deploys, and manages the security system on a day-to-day basis within the organization. Conversely, the Lead Auditor acts as an independent and impartial evaluator responsible for verifying the system’s compliance through evidence, without ever providing advice.
To uphold the fundamental principle of independence, a professional cannot serve as both the Lead Implementer and the Lead Auditor on the same project.
-
How soon and how are the results of the LSTI exam communicated?
Certification decisions and scores are communicated individually to candidates by email within a maximum of 2 weeks after the exam. To comply with the strict confidentiality and impartiality requirements of ISO 17024, no results will be provided by phone. -
What materials are allowed on the day of the exam?
The certification exam administered by LSTI allows only the use of official standards (including the ISO/IEC 27001, ISO/IEC 27002, and ISO 19011 handbooks) in paper format. In order to accurately simulate the working conditions of an auditor in the field while preventing cheating, personal notes, training binders, laptops, and general internet access are strictly prohibited throughout the entire online exam. -
How can I verify the authenticity of an auditor certificate issued by LSTI?
The validity of a certificate can be verified directly with LSTI. The certification body publishes and maintains a public registry of certified individuals on its website. This official registry allows employers, audit firms, and clients to instantly and transparently verify the active status of an auditor’s certificate of competence. -
Does LSTI offer ISO 27001 training courses?
No, LSTI does not offer any training programs. LSTI operates exclusively as an independent certification body. To take the exam, you can register as an independent candidate if you already possess the necessary skills, or enroll in a preparation course at one of the training organizations accredited by LSTI. This strict separation between training and the exam ensures the certification’s complete impartiality.
