Schools are inspected by Ofsted to provide information to parents, to promote improvement and to hold them to account for the public money they receive. School inspections are required by law. They provide an independent assessment of the quality and standards of education and achievement.
All Catholic schools are also subject to a diocesan inspection (known as a section 48 inspection) at least every five years. St Helen's is inspected by Southwark diocesan inspectors appointed by the bishop (Education Act 2005). St Helen's was last inspected in October 2015 and was judged to be a "good school with many outstanding features."
