This is a very subjective question so you might get a variety of answers. One website that tries to compares schools is called http://www.GreatSchools.org
Here is what they say about Caldwell High School.
I am a firm believer that with the right parenting and oversight, a good student will do well in almost any school and that a poor student will do poorly even in "good schools".
I wish I could give a more finite answer.
Best of luck!
PS, which ever school district you decide on, I can pull direct listings of homes in that exact district if you like.
