Certifications are acknowledgements granted to partners for achieving certain milestones. Usually, they acknowledge that a partner has completed product training and is now qualified to represent the company as a partner. They are most often earned as a part of the onboarding process, wherein the partner must learn about the vendor's product to a degree that allows them to comfortably sell/market/share it. Certifications are usually earned early on in the partner journey, but they can also be earned again after product updates or new releases that require subsequent training.
