 The educational opportunities for secondary modern pupils were limited compared to those at grammar schools , prompting criticism of the <unk> system . In 1965 , the Labour Government issued <unk> 10 / 65 requesting Local Education Authorities implement comprehensive schooling . In 1971 Sleaford parents voted in favour of comprehensive education , but rejected the Council 's proposals . A new plan which envisaged Carre 's becoming a sixth form college was supported by parents in a vote ( 1 @,@ 199 to 628 ) , albeit with a 50 % turnout ; the County Council approved it but allowed governors a veto . Following negotiations with governors at Carre 's , the scheme was revised so that Carre 's would be an 11 – 18 school and <unk> Sleaford Secondary Modern 's Church Lane site . Despite support from most staff and all three <unk> , Lincolnshire County Council voted to return the scheme for consultation in 1975 . A new system was proposed which retained all three schools , and when the Government ordered the Council to choose a comprehensive scheme in 1977 it submitted that proposal , which had become popular with parents . The next year the government dismissed it on grounds that the Sixth Forms would be too small , but the council voted against the two @-@ school system once more .
