The best and most accurate way to find out your partner certification status is to check your University Partner profile. The easiest way to notice that your company is certified is the Partner Certification badge in the top right of the profile. You will also see the text "cPanel Certified Partner" and the expiration date below the company name. For example:
To find your Partner profile, first, navigate to https://university.cpanel.net. Next, type your company name into the search field in the top left. And finally, on the search results page, click your company name under the Partners results section.
Inversely, if you want to know how your company is doing towards certification, a Branch Admin can do this through their cPanel University Branch Admin dashboard.

First, check out this chart for how many certified students you need based on your license count.
Then, use the Branch Admin training matrix to see how many members in your branch have completed the requirements so they can count towards partner certification.
