List 99 (also known as the Children’s Barred List and, later, as information held under Section 142 of the Education Act 2002) was a controversial, confidential register of people barred from working with children by the Department for Education and Skills (DfES) In the United Kingdom. The list contained the names, dates of birth, aliases, and national insurance numbers of those people deemed not suitable to work with children in schools, social work and voluntary settings.
