The Child Protection in Sport Unit (CPSU) is a partnership between the NSPCC, Sport England, Sport Northern Ireland and Sport Wales. In Scotland there is a similar partnership between Children 1st and sportscotland.
The Unit was founded in 2001 to work with UK Sports Councils, National Governing Bodies (NGBs), County Sports Partnerships (CSPs) and other organisations to help them minimise the risk of child abuse during sporting activities. This followed a series of high profile cases of abuse of young athletes by those in positions of trust such as coaches in the sports. The CPSU works to help achieve the NSPCC mission to end child abuse.
