Other Certifications

Should there be any other commissioning certification programs missed out in this article, please write them in below comments section.


There are pretty different kinds of certifications for different levels of experience. One may get a Cx certification for their needs whether be it for advancing in their career or for certifying their current level of knowledge in the industry. One key element not to miss out is recognition: Each certificate has its own area of recognition, so one should check it before pursuing a specific certificate.
