The bill involves, among other things, a trade-off of a three year delay for a one-year pause. Florida parents don't believe one year is sufficient to wait on implementing full on "accountability measures" (the usual crap soup of testing etc), and that aspect has been a sticking point. The bill sticks with the grading of schools as well, which people are unhappy about in FL. And it attempts to create a "smooth transition" for Florida education.
In this video, you can find Rep. Adkins making her impassioned plea (at the 1:36:00 mark). She manages to use Ethan Rediske as a political prop without even naming him or the bill that she has co-opted, and she invokes her own motherhood and speaks with oh-so-much-deep feelings. She has allllll the feelings. Schools need to be graded so that schools feel urgency to do a good job (because schools never work well unless they're threatened). But let's not talk about that. Let's remind you all how much you want to do something rational and right for special needs students.
