The ITIL Practitioner is considered the next step in the ITIL progression after achieving the ITIL Foundation (which is a prerequisite). It emphasizes the ability to adopt, adapt and apply ITIL concepts in an organization. Although the Practitioner certification is not required for upper-level ITIL credentials, achieving Practitioner certification provides three credits toward ITIL Expert certification. You can prepare for the Practitioner exam through self-study, in-person classroom learning or online and distance learning options. The Practitioner exam is 40 multiple-choice questions and requires a minimum score of 70 percent, or 28 correct answers,  to pass.
However, ITIL certification is different. Having an ITIL certification doesn’t make us an ‘expert’ for any specific skill set. As you might already be aware, ITIL is a set of best practices and is descriptive in nature. Hence an ITIL certification isn’t about doing your job, but merely about knowing the ITIL principles. In fact, that’s precisely the reason why AXELOS have now added the ITIL Practitioner level which makes it mandatory for IT folks to apply their theoretical knowledge in practice.
