Can a minor be questioned at school without parent present in North Carolina?

They have the ability to waive their Miranda rights, but if they ask for their parents it is the same as asking for a lawyer, and from then on a parent must be present.

Another View: Please define "questioned."

If you are referring to a School Resource Officer (SRO) simply speaking with a student while on the school grounds, it most certainly IS allowed. The situation might change only if the juvenile/student was actually in custody, or being questioned as a suspect in an offense. Then a parent/guardian or school administrator should be present to act as, not only a resource for the minor, but as a witness for the officers actions.
