If you want to look a teacher up, here's a link that works in 2024, even if it's not really officially on the main Florida Department of Education website anymore. You'll probably have to click around the website, like the main logo or something. It's clunky.
You do have the right to know if your kids' teachers are licensed, even if your charter school overlords don't want to tell you. https://flcertify.fldoe.org
That said, my license expires in June of 2024, and I don't have the silly credits / special Ed / reading certs required to renew, so whatever. I imagine with low pay, high stress, hoops to jump through to renew, and the worry of jail time for using the wrong books, plenty of Florida teachers are letting their licenses lapse.
