When Ofsted was created the original plan was that inspectors would not be drawn from education. the plan was to give parents an independent review of a school untainted by the education establishment. This plan was quickly replaced by a system that existed until 2005. This system was based on schools being inspected by teams containing three types of inspector. Each team was led by a 'registered' inspector. They were accompanied by a number of 'team' inspectors, the number of which depended on the size of the school. Each team also contained 'lay' inspector recruited from outside the world of education. In September 2005 the distinction between registered, team and lay inspectors was removed and all contracted inspectors (as opposed to directly employed HMI) became 'Ofsted inspectors'.
