Although ITIL V3 was published a few years ago, not all IT Service Management professionals are aware of the new ITIL V3 Qualification Scheme, which continues to evolve.
A qualification scheme is a roadmap for achieving a Professional Certification. It typically consists of a set of intermediate Credentials which build and depend upon each other which in total demonstrate that the skills and knowledge embedded in the Certification have been achieved. The ITIL V3 qualification scheme is very different from the V2 in that it defines different subject matter ladders to climb, has more levels to the scheme, provides guidance on how to achieve each type and level of Certification, delineates the prerequisites for each level and lays out the roles and responsibilities of the different organizations participating in the scheme.
Although much of ITIL content is the same between version 2 and version 3, its scope, its orientation and the structure of its advice have evolved significantly. The new scheme takes these changes into account and therefore has become a modular points-based system,
There are several significant differences:

There is little difference. The examination questions used, the scoring and the certificates delivered are equivalent. There is a database of exam questions that all Examination Institutes use to create their examinations.
APM Group is committed to providing examinations in a wide array of languages, including English, German, French and Italian. Normally, the English version is available first, with the other languages following within a few months. For the availability of an exam in a given language, consult the Examination Institutes (see below).
Existing ITIL certifications continue to be valid. However, as IT Service Providers make the move from ITIL V2 to ITIL V3, the older certifications will become of lesser interest. The ITIL 3 scheme includes several “Bridge” examinations that allow existing holders of ITIL certificates to upgrade their certifications to ITIL V3 via a “fast-track”. They may take shorter and less expensive bridge examinations that assume knowledge of ITIL V2, and concentrate on the differences between ITIL V2 and ITIL V3. An existing ITIL Foundation Certificate is worth 1.5 credits, a Practitioner Certificates are worth 2 (singles) or 3.5 (clusters) credits, and a Manager’s Certificate is worth 17 credits. By passing a bridge examination (Foundation Bridge and Manager Bridge), one can receive sufficient points to attain the corresponding ITIL V3 level.
As part of the Qualification Scheme, the APM Group and its Examination Institutes authorize companies as Training Organizations (ATOs), and individuals as trainers (ATs). There are numerous ATOs which can be found by consulting the Examination Institutes web sites (see below).
As in the past, certification at levels higher than Foundation requires participation in a course offered by an ATO. Certification at the Foundation level does not require this participation, although it is recommended.
All examinations are delivered under the responsibility of an Examination Institutes (EI). The EI decides whether to deliver examinations using the Internet, or deliver paper-based examinations. They are completely equivalent. For paper-based examinations it may take 2-3 weeks to learn the results.
