I think that having it as part of the curriculum at school makes sense. If you're in high school, in grade nine you get this, or you get it in grade 10 or grade eight or something, and it's talked about in the same way as history, health education, or that sort of thing.
My personal experience is that I had a patient who went to something in high school where they talked about it and then he went to his guidance counsellor and said he thought he had a mental health problem, so that was a way for him to seek help. If it's part of the regular curriculum, I think that could be helpful.
