Be aware that ITIL uses a credit system for the Foundation through Expert levels, in which each certification earns a certain number of credits. Ultimately, a total of 22 credits is required to achieve ITIL Expert certification. (The ITIL Master has its own set of requirements, which you'll read about shortly). The following graphic shows the structure of that certification scheme and its corresponding credits.
If you work in IT, you’ve likely heard of or worked with ITIL. Perhaps you’ve even considered pursuing ITIL certifications. But is the investment worth the return? We’re taking a look at the cost of ITIL certifications at various levels and the benefits you can expect, so you can decide whether it’s an appropriate investment for you and your business.

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.
