I don't know about Florida but where I am all you need is a high school diploma and experience working with children. College education just allows you to work longer before you need to renew your license. It's a joke but everyone knows that substitute teaching is a thinly disguised babysitting gig. If Florida is purging groomers then this is a more than acceptable price to pay. For 3rd grade the big thing is being able to work with kids. Any retard can teach the content.
