You may also want to visit the Palm Beach Schools web site noted below. This includes links to each school, shows boundary lines and even has a "school finder", a tool that allows you to input an address for a potential home you may be looking at and tells you the current corresponding schools for that address.
I have a 9 & 13 year old, and both go to public schools in P.B.Gardens. They are in general fine, certainly one or two are better than some others.
Feel free to contact me if you want more on my opinion.
