ISO/IEC 20000-1 Certification

Third-party ISO/IEC 20000-1 certification from an IAS-accredited certification body. Prove your IT service management to government buyers and enterprise clients, and stand out in a market that runs on SLAs.

The Standard

What Is ISO/IEC 20000-1?

ISO/IEC 20000-1:2018 is the international standard for IT service management systems (SMS). It defines how a service provider plans, delivers, and improves IT services, covering service levels, incident and change management, capacity, continuity, and supplier relationships.

Certification means an accredited, independent certification body has audited your service management system in operation and confirmed it conforms to the standard. It is the certifiable counterpart to ITIL practice.

Transfers

If your current certification body is slow to schedule, slow to answer, or priced for someone else's overhead, transfer your accredited certificate to GMCS. Your certification cycle and surveillance schedule continue uninterrupted, and in most cases there is no repeat of Stage 1 and Stage 2.

FAQ

ISO/IEC 20000-1 Certification Questions

How does ISO/IEC 20000-1 relate to ITIL?
ITIL is a body of practice; ISO/IEC 20000-1 is the auditable standard. An organization running ITIL-aligned processes is well positioned for certification, and certification turns that alignment into verifiable proof.
How long does ISO/IEC 20000-1 certification take?
Timing depends on the readiness of your service management system. Once it is documented and in operation, certification is a two-stage audit, and many organizations complete it within a few months.
How much does ISO/IEC 20000-1 certification cost?
Cost is driven by organization size, number of sites, and the scope of services covered. GMCS maintains discounted pricing for organizations with fewer than 100 employees.
How long is an ISO/IEC 20000-1 certificate valid?
Three years, maintained by annual surveillance audits, followed by a recertification audit at the end of the cycle.
Can we transfer our existing ISO/IEC 20000-1 certificate to GMCS?
Yes. An existing accredited certificate can transfer to GMCS without restarting your certification cycle.
Does GMCS provide ISO/IEC 20000-1 consulting?
No. GMCS is an independent certification body. Accreditation rules prohibit certifying a system we helped build, and that independence is what keeps your certificate credible.
