Proven Preparation Strategies

These evidence-based strategies will help you study more effectively for the ISO 20000 Certification certification:

1. Active recall over passive reading — Test yourself frequently rather than re-reading notes. Practice tests are more effective than highlighting textbooks.
2. Spaced repetition — Review material at increasing intervals (1 day, 3 days, 7 days, 14 days) to move knowledge into long-term memory.
3. Focus on understanding, not memorization — The exam tests application of concepts. Understand why an answer is correct, not just what the answer is.
4. Simulate exam conditions — Take practice tests in a quiet environment with the same time constraints as the actual exam.
5. Join study groups — Discussing concepts with peers reinforces understanding and exposes you to different perspectives.
6. Use official study materials — Start with the certifying body's recommended resources, then supplement with third-party materials.
7. Track your progress — Keep a log of practice test scores to identify trends and weak areas that need additional review.

Sample ISO 20000 Certification Practice Questions

Try these questions from our free ISO 20000 Certification practice tests. The correct answer and an explanation follow each question.

1. A company has successfully implemented an SMS and achieved ISO 20000 certification. To maintain this certification, the company must demonstrate a commitment to continual improvement. Which of the following activities BEST demonstrates this principle?

   • A. Maintaining the same service level targets year after year.
   • B. Conducting a management review of the SMS only when a major nonconformity is found.
   • C. Analyzing trends in service performance and identifying opportunities for enhancement.
   • D. Keeping all service management processes and documentation unchanged after the initial audit.

Answer: C. Analyzing trends in service performance and identifying opportunities for enhancement.

Continual improvement is a core principle of ISO 20000, driven by the PDCA cycle. Analyzing trends, reviewing performance, and proactively identifying opportunities for improvement are key activities that demonstrate an ongoing commitment to enhancing the SMS and service delivery. The other options suggest a static or reactive approach, which is contrary to the principle of continual improvement.

Answer: A. Every three years.

ISO 20000 certification is typically valid for a period of three years. During this three-year cycle, surveillance audits are conducted annually to ensure ongoing compliance and continuous improvement of the Service Management System. At the end of the three years, a comprehensive re-certification audit is required to renew the certificate and maintain compliance.

Answer: A. Any organization that implements IT service management.

ISO 20000 is a generic standard applicable to any organization, regardless of its size, type, or industry, that provides IT services. The key criterion for eligibility is that the organization has an IT Service Management System (SMS) in place that it wishes to have certified against the standard. It is not restricted by factors such as size, sector, or governmental status.

Answer: C. Sampling and reviewing actual change records against defined criteria

Record sampling provides objective evidence that change records meet defined content and approval criteria, satisfying the auditor's need for factual evidence.
