Document 4: Royal Grammar School, Guildford: The Royal Grammar School, Guildford (originally "The Free School"), commonly known as the RGS, is a selective independent day school for boys in Guildford, Surrey in England. The school dates its founding to the death of Robert Beckingham in 1509 who left provision in his will to 'make a free scole at the Towne of Guldford'; in 1512 a governing body was set up to form the school. The school moved to the present site in the upper High Street after the granting of a royal charter from King Edward VI in 1552. Around that time, its pupils were playing cricket and their activity was later documented as the earliest definite reference to the sport. The school's Old Building, constructed between 1557 and 1586, is the home of a rare example of a chained library. It was established on the death of John Parkhurst, Bishop of Norwich, in 1575. Although defined as a "free" school, the first statutes of governance, approved in 1608, saw the introduction of school fees, at the rate of 4 shillings per annum, along with the school's first admissions test. During the late 19th century the school ran into financial difficulty, which nearly resulted in the closure of the school. A number of rescue options were explored, including amalgamation with Archbishop Abbott's School. Funds were eventually raised, however, which allowed the school to remain open, although boarding was no longer offered.

Document 11: Carre's Grammar School: 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. The indenture restricted the endowment to £20 without accounting for inflation, causing the school to decline during the 18th century and effectively close in 1816. Revived by a decree from the Court of Chancery in 1830, new buildings were constructed at its present site and the school re-opened in 1835. Faced with competition from cheaper commercial schools and declining rolls, Carre's eventually added technical and artistic instruction to its Classical curriculum by affiliating 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.
