Without an address it is hard to say but one of my favorite sites when it comes to school ratings is http://www.greatschools.org and if you have an iPhone check out their app which is also a fantastic tool. I love their site, use it often and highly recommend it to my clients who are interested in finding the best schools for their children's education. GreatSchools profiles public, private and charter schools and has a great format for readers to leave comments. Besides their rating system the comment section is the best place to go to get real life feedback from children who attend the schools as well as their parents. You will find that overall Jupiter has one of the best school districts in Palm Beach County.
You might also want to check out the Florida Department of Education School accountability reports which are also a wealth of information and can be accessed with this link;
After doing your homework on-line I always recommend parents visit the school live and in person prior to making any real estate decisions in that district and if you need assistance let me know as I would be happy to show you around. I hope this information is helpful but if you need anything additional please do not hesitate to give me a call.
Always at Your Service,
