To recognize the candidate investment in ITIL qualifications and endorsed Complementary Qualifications, a credit system has been introduced to support the ITIL scheme. Within the ITIL Credit System, all ITIL and ITIL related qualifications have been assigned with a specific credit value, based upon the content of ITIL material which is covered by the qualification. Upon successful completion of any ITIL examination recognized under the scheme, a candidate will be rewarded with both the certification and the attributed credits. The credits earned through this Credit System can then be used by candidates who are interested in achieving the ITIL Expert Level of certification, which requires candidates to meet a specific set of key requirements, which include earning a required number of credits (22) from qualifications which cover the full spectrum of ITIL Best Practice.
