Under a little-known provision (Section 9528) of the No Child Left Behind Act, public high schools must hand over personal information about students to local military recruiters. The good news is, parents can (in theory) get their kids removed from this list by submitting a request in writing to their school district superintendent.
LeaveMyChildAlone.org provides an online tool that makes it easy to "opt out" your kids from the list that your local high school is required to release to military recruiters. The site also provides activist tools to help change the law that lets military recruiters prey on our children without their parents' explict permission.
