Is there a government agency that oversees education issues with regard to local schools?

The United States government agency that oversees issues with regard to education is the Department of Education. Because all government agencies are regulated by what's termed “administrative law”, any violations of rights in the area of school will become an administrative law matter. The federal Department of Education can work in conjunction with each individual state's department of education. If you feel that your rights or the rights of your child have been violated, the first place to start is with the local school district. You should first address your concerns with the local authority. If you feel that your concerns have not been adequately addressed, finding a reputable attorney that is versed in and has experience in dealing with educational issues would be advisable.
