‘ContactPoint’ – formerly the Information-Sharing Index
The Children Act 2004 empowered the Secretary of State for Education to create a database (or databases) of everyone in England who is aged under 18. In July 2007, the regulations that will bring this first national database of children into being were passed by Parliament.
The government has announced that the database will be called ContactPoint. It was originally known as the Information-Sharing Index, but re-branded in February 2007 because of negative publicity about information sharing.
