The ITIL V3 Qualification Scheme introduces a credit system to achieve Expert Certification in ITSM. You will need a minimum of 22 credits achieved in a balanced selection of V3 subject areas to gain Expert Certification. Click here to learn more about the V3 Qualification Scheme.
You can also accumulate credits from any V1 or V2 certifications you already hold and can add to these with either V3 "Bridging" qualifications, or by successfully completing further V3 modules.
It is strongly recommended that the V3 certifications you choose are complementary to any existing certifications you hold. This will help you to achieve a balanced ITIL knowledge base and sufficient credits.
