Schools which are independent of the City Council include Hymers College and Hull Collegiate School. The latter, which is run by the United Church Schools Trust, was formed by the merging of Hull Grammar School and Hull High School. There is a further education college, Hull College, and two large sixth form colleges, Wyke College and Wilberforce College. East Riding College operates a small adult education campus in the city, and Endeavour Learning and Skills Centre is an adult education provision operated by Hull Training & Adult Education. Hull Trinity House Academy has been offering pre-sea training to prospective mariners since 1787.
