 Carre 's Grammar School is a selective secondary school for boys in Sleaford , a market town in Lincolnshire , England . Founded on 1 September 1604 by an indenture of Robert Carre , the school was funded by rents from farmland and run by a group of trustees .

Faced with competition from cheaper commercial schools and declining rolls , Carre 's eventually added technical and artistic instruction to its Classical curriculum by <unk> with Kesteven County Council in 1895 . Following the Education Act 1944 , school fees were abolished and Carre 's became Voluntary Aided . New buildings were completed in 1966 to house the rising number of students . After plans for comprehensive education in Sleaford came to nothing in the 1970s and 1980s , Carre 's converted to grant @-@ maintained status in 1990 . Foundation status followed and the school became an Academy in 2011 ; a multi @-@ Academy trust with Kesteven and Sleaford High School was formed in 2015 .
