Go to http://www.greatschools.net. You can compare across district lines, various schools, etc. the Dallas Realtor is right - we cannot make those judegements for you, or "red-line" any areas - tell you areas that may be less desirable than others. You must make those judgements for yourself. But there is a lot of information out there, and we can at least direct you to it so you can make your own informed decisions.
