One of my students smokes. It was a rumor that I heard from a teacher who heard from a parent. I told her I wanted to ask her a question, and that it had nothing to do with discipline. “Do you smoke?” “That’s a very strange question, but I’ll tell you the truth, yes.” She has smoked for three months, and she is trying to quit. She tries not to smoke in school uniform, she mostly does it while at work. She asked if other teachers knew. I said that it was just a rumor to (the dean of discipline), and we didn’t know if it was true. She asked me to “just keep it between us.” <----- My question is: Should I keep this information in confidence? Or should I tell the dean and also her parents? I think that she is sixteen. Background: My school is in a different country where we do care about student lives outside of school also. I'm not sure about the legal status of her smoking, but that isn't really the point. I am a homeroom teacher concerned with the overall wellbeing of the students in my homeroom. I feel like the right thing to do is to inform the parents and the dean, but I want to think carefully before I act.
