As early as the 8th century schooling was available at Louth, but the oldest reference to a school is in a passage by Simon de Luda, the town's
schoolmaster, in 1276. Leading figures in the local community petitioned the King,
Edward VI, to secure the school's future, and on 21 September 1551 the school was given a plot of land and money raised from three fairs by the king, In 1564,
Elizabeth I granted the manor of Louth and some additional property to support the school. In February 2024, the school was back in the news when teachers went on strike over adverse management practices, which they claimed were leaving them "exhausted and stressed". A resolution was reached after one day of industrial action. Previously a
foundation school administered by
Lincolnshire County Council, King Edward VI Grammar School converted to
academy status in September 2015. However the school continues to coordinate with Lincolnshire County Council for admissions. In 2022, completion of the new sports hall was done. The new facility provides 4 changing rooms, a fitness suite and a dance studio. There is the main hall as well. At the start of the academic year 2025-2026, the school renovated the library building with funding from the will and last testament of former headteacher of the Girls’ school, Christine Wilkinson. ==Admissions==
