Grantham College is a British further education and Sixth Form college located in Grantham, Lincolnshire. It was known as the Grantham College for Further Education. In the early 1970s, there were advanced proposals by Kesteven County Council (based in Sleaford) to abolish the eleven-plus selection system in the Grantham area and use Grantham College as the only sixth form in the town. Mary Large, the Chairman of the Kesteven Education Committee, said that more young people preferred to go to college rather than stay in a school sixth form because of the 'more adult atmosphere'. In 1973, the Education Secretary, Margaret Thatcher, had to approve the plan, which involved converting her former school, KGGS, into a mixed comprehensive. It was not approved. In April 1974, control of the college passed from Kesteven to Lincolnshire in Lincoln. Later in 1979 it became Grantham College of Further Education. In the early 1990s, control passed to the FEFC, then the East Midlands LSC (based in Leicester). Also in the early 1990s, it became known by the shortened Grantham College as was known as an Associate College of Nottingham Trent University.
