This is a presentation on the current findings from my Professional Doctorate with the University of Central Lancashire (UK), into exploring opportunities through school-policy review to improve teenager's mental health in school. This research is designed to help and support pupils in school, who may be suffering in silence at the expense of school leaders' policy decisions. The research focuses on four key policies: curriculum, teaching and learning, behaviour and assessment. The presentation will review international differences and cultural views on children's mental health and suggest ways to go forward in a post-pandemic world.
