Do you know how the magnet schools and/or school reassignment work down here?

I’m a member of various subs for South Florida and pretty frequently there are posts about school. I’ve been surprised to see the number of people that don’t know that you don’t HAVE to send your child to their assigned school. The school districts (I have experience with Palm Beach and Broward and assume that Dade is the same) have instruction on what to do if you want to send your child to a different school.
