Kathy- You should always refer directly to the County school district to find out this info. You can call or they have an interactive attendance map where you can plug the address of whichever home you are interested in and it will immediately tell you.
I'm not an agent, but I live in the neighborhood that you are looking into. St. Andrews middle isn't too bad, but I would recommend a little bit of research on elementary school and high school. There are many lottery/ charter/magnet schools in this area that you can apply for. Hope this helps.
