Ofsted - the Office for Standards in Education, Children's Services and Skills - inspects and reports on anywhere that provides education for young people in England, including schools, nurseries and childminders.
Schools or organisations are inspected every four years or 30 months depending on their status.
Many parents rely on Ofsted ratings to help them choose a school or nursery.
