In England, a City Technology College (CTC) is a state-funded all-ability secondary school that charges no fees but is independent of local authority control, being overseen directly by the Department for Education.One fifth of the capital costs are met by private business sponsors, who also own or lease the buildings.The rest of the capital costs, and all running costs, are met by the Department.City Technology Colleges teach the National Curriculum, but specialise in mainly technology-based subjects such as technology, science and mathematics.Like maintained schools, they are regularly inspected by the Office for Standards in Education.CTCs also forge close links with businesses and industry (mainly through their sponsors), and often their governors are directors of local or national businesses that are supporting or have supported the colleges.
