Diolch, Llywydd. I've agreed to give a minute in this debate to Mark Isherwood, Jack Sargeant, Hefin David and John Griffiths. The emotional and mental well-being of young people is a challenge, and that has come to the forefront in recent times. It has been recognised by politicians, parents, teachers and by young people themselves. It was telling that so many of the young people who stood for the Youth Parliament made this their priority. Young people today have more information at their fingertips than any other previous generation, but face greater challenges on the social, emotional side of growing up. It's our responsibility to listen and act. Adverse childhood experiences can have a significant detrimental impact on the life chances and attainment of young people. In 2015, research by Public Health Wales found that 47 per cent of the Welsh population had experienced at least one ACE before the age of 18, and 14 per cent four or more. Attitudes, beliefs and behaviours learnt during these very early years are often carried into adulthood, and it's imperative that we do all we can to support and nurture children. If we get things right early on, there is an ever-growing mountain of evidence to show that this will have a positive impact on not only the individual, but on society as a whole. 

A mentally healthy school sees positive mental health and well-being as fundamental to its values. Emotional health and well-being cannot be confined to just lessons. It must be part of the very ethos of the whole-school approach. I'm proud to say that there's been some really positive progress on this subject through the Assembly and through the determination of my colleague Lynne Neagle. Lynne has been a passionate advocate of improving the mental and emotional well-being of our children and young people, and has been a strong advocate for a whole-school approach. I'd like to take this opportunity to pay tribute to Lynne's work and the Children, Young People and Education Committee. The CYPE committee produced a clear, evidence-based report, 'Mind over Matter', which sets challenges to Welsh Government. 'Mind over Matter' found broad consensus that school settings are key to promoting emotional well-being and good mental health, that the preventative approach needs to be embedded within the ethos of a school, not just the lessons taught, and that teachers are not solely responsible, but it requires joint working between professionals from across sectors—health, education, social care, third sector and youth work are key.
