Check out this website. It tells you everything you need to know from staff, students, ratios, school test scores etc...
The school that got the highest ranking scores for kingergaten readiness is in Bradenton and it's called Little Footsteps at the Ranch. My son didn't go there. He went to A Readiness Learning Academy. They ranked pretty high too for VPK. The only problem with that school is they have a little over a 2 hour nap period, which my son didn't nap so he didn't care for that school too much. Most of the schools around here are full so you have to get in early or be put on a waiting list.
Good Luck :)
