As a trainer I would love to see badges awarded when Certifications are completed. My ideal version looks like this: I design a custom badge and then add requirements to unlock it - these will be tied to a specific certification or playlist: for instance, when a teller completes teller training the "Teller" badge would unlock. Or, when someone completes the "Sales Superstar" playlist I create they unlock the "Sales Superstar" badge.
These badges would show up on a badge page/trophy case. It would show how it was earned and when it was earned. I'd also like other employees to be able to see these badges...a newsfeed of badges on the Learning Landing Page would be great so people could fistbump/like/upvote when a badge is unlocked.
