does NC statutes give DSS the right to interview children in school without parents permission?
They do it all the time, and they did it with my kids here in the Northeast. Their suspicion be "Emotional Maltreatment" which covers just about any adult behavior that isn't unblemished. I have heard that they often interview children when they own no suspicions about their parents at all, looking for evidence just contained by case. I wish they would spend their time with serious problems such as battering, adjectives, or sexually abusing.
Yes. If there are allegations of physical or sexual abuse they can and will. If not contained by school, they'll go to the day concern, camp, or their friend's house. They want to be able to speak to the child before the parents can threaten or put in the picture them what to say.
