The document discusses children's rights to participation according to the UN Convention on the Rights of the Child (UNCRC). The UNCRC recognizes the right of children to have a say in matters affecting them. However, true participation, especially for young children and those with disabilities, still lags behind what legislation and policy requires. The document also notes that while there are challenges like inequalities and punitive criminal justice systems for children in the UK, many children also report being happy and wanting to succeed in life.
