The ITIL certification scheme now offers a modular approach. Each qualification is assigned a credit value; so that upon successful completion of the module, the candidate is rewarded with both a certification and a number of credits. At the lowest level – Foundation – candidates are awarded a certification and two credits. At the Intermediate level, a total of additional 15 credits have to be earned. These credits may be accumulated in either a "Lifecycle" stream[note 1] or a "Capability" stream;[note 2] or combination thereof. Each Lifecycle module and exam is three credits. Each Capability module and corresponding exam is four credits. A candidate wanting to achieve the Expert level will have, among other requirements, to gain the required number of credits (22). That is accomplished with two from Foundations, then at least 15 from Intermediate, and finally five credits from the "Managing Across the Lifecycle" exam. Together, the total of 22 earned credits allows a person to request designation as an ITIL Expert. Advancing from the expert to the master level does not require additional credits, but does require at least five years of IT domain work experience and an extensive usage of ITIL practices.
ITIL Intermediate (Lifecycle Stream): Addresses aspects of ITIL from a holistic, lifecycle perspective. Lifecycle may be more suited to those with managerial responsibility looking at the overall IT Service Management picture. The Service Strategy course in particular is very much rooted in the broader corporate strategy and governance environment.
ITIL 2007 edition (previously known as ITIL Version 3) is an extension of ITIL Version 2 and fully replaced it following the completion of the withdrawal period on 30 June 2011. ITIL 2007 provides a more holistic perspective on the full life cycle of services, covering the entire IT organization and all supporting components needed to deliver services to the customer, whereas ITIL Version 2 focused on specific activities directly related to service delivery and support. Most of the ITIL Version 2 activities remained untouched in 2007, but some significant changes in terminology were introduced in order to facilitate the expansion.
