How current is the data on sinkholes?

I will be moving to Orlando in 6 months for a new job. I have a child in elementary school and I want to make sure the new neighborhood we move to in Orlando is close to a good school. Where can I view the elementary schools in the Orlando area and also see there school grades?

I am thinking about buying a new home in Florida and have already found a few potential properties that I am very interested in. However, I have heard a lot of about sinkholes in Florida and I was hoping to find out if the houses I am looking at are close to any current sink holes or if they are in areas that have an abundance of sinkholes.
