Searching for resources reveals there are few focused on teaching children and young people the decision-making process, even fewer for those with special educational needs (SEN), but lots to practise decision-making. The Mencap website1 cites statistics showing that 40% of adults with learning disabilities experience mental health problems; this is considered to be about double the estimated prevalence for mental health problems in the general population. Therefore, developing and enabling children’s and young people with SEN decision-making ability is not just cultivating a life skill, but helping to promote and support their mental well-being. The Children and Families Act 2014 introduced Education, Health and Care Plans and places an emphasis on preparation for adulthood from the earliest age, including children and young people participating in decision-making about their education. The chapter also presents an overview of the key concepts discussed in this book.
