Each ITIL certification has been assigned a specific credit value, based upon their level of ITIL content. Upon successful completion of any ITIL examination recognized under the credit system, a student will be awarded both the certification and the credits attached. The credits earned through this system can then be used towards the ITIL Expert level of certification, for which candidates must have earned a required number of credits (22) from qualifications which cover the full spectrum of ITIL best practice.
