Listing verification by admin (not claimed listings)

Is there a way I can display on a listing whether a business has been endorsed by the site? For example. if I have a shop listed, which has been claimed by the owner, fine. But additionally to that I would like it to state whether it has been endorsed by my website (like a certification type thing). My website lists shops that provide a particular service, which a lot of shops in that category don’t perform properly so I would like to be able to highlight the ones who do. But it would have to be only editable by admin but seen by all.
