Actually, there are programs that have an education specialty and or classes designed for such. I know that Duke has an excellent education clinic and class. Alex doesn't seem to have all of the information. Additionally, there are plenty of jobs to be had by people with a JD (and even a master's in education in your case). Just think about it...I am not sure what avenue of the educational system you wish to pursue, but you could 1) Work in the Dept. of Education, 2) Work perhaps in public interest representing students who have been expelled from school (which is similar to Duke's program), 3) you could become the Dean of a school (not just law school, but any other type of institution), you could work for a local school district...I could go on and on. Just do a little investigation and I am sure you can find a program that is for you. Just don't limit yourself to law classes...branch out if you are able and if you can get your master's at the same time, that's even better. Duke has a great plan for JD/MA students.
If you can't tell, I go to Duke and I am a dual degree candidate, though not in education!
Take care and best of luck.
