If a teacher finds out that a student is injuring themself does she have any legal right to tell the parents?

Just for specific clarification the stundent is 14, both birth parents are legal guardians. The student has been cutting OCCASIONALLY for the past year. The teacher knows for sure, and has spoken with the student about it. The student has made it very clear that she does not want her parents to know. There are no indications of suicide or cidal attempts, or expression of suicidal or cidal thoughts. There is no record of the student becoming violent, and no record of any psychological condition other than mild-moderate depression. The stundent lives in Georgia if the law (if even in existence) varies with the state. Also just to clarify I don't want any advice on whether or not the teacher SHOULD tell the parents, just if they CAN. Thank you for your time.
