Rising Stars are recognized for providing high-quality answers to other users. Rising Stars receive a certificate of achievement and are on the path to becoming Community Leaders.
And the accreditations are "free". But to be accredite it is necessary to go on Charlie (the portal of the partners), to pass a certain number of quiz and have 2 certifications I'm not 100% sure so the best way is to contact Atlassian, you can create a request on Atlassian support portal : https://support.atlassian.com/servicedesk/customer/portal/9
