Knights Templar School is a co-educational secondary school with academy status located in the market town of Baldock in North Hertfordshire, England. In a February 2006 OFSTED report, the school was described as "outstanding", one of only eight secondary schools in Hertfordshire to be so recognised. It retained its "outstanding" status following a further OFSTED inspection in February 2009. The Knights Templar School gained Academy status on 1 April 2011. Following an OFSTED inspection in October 2012 the school was categorised as "good".
The school opened the day before the start of the Second World War in 1939 as the Baldock Secondary School, and was renamed The Knights Templar School by Vivian Crellin, a former headmaster of the school and a scholar of Baldock's medieval history. Since that time the school has seen new buildings and ever increasing pupil numbers, leading to oversubscription every year. The school claims no connection with the Masonic order of Knights Templar or with The Da Vinci Code – rather, it is named after the chivalrous medieval order of the Knights Templar, who founded Baldock and built the original 12th century parish church of St Mary the Virgin in the town. The motto of the Knights Templar School is "Courage and Courtesy".
The school Houses are Crellin, Hancock, Hine, Pembroke, Bennett, Knights and Templar, named after former Headmasters of the school (Hancock and Crellin), local educationists (G.H. Bennett and Alderman Neville Hine who for many years was Chairman of Managers of Baldock C.C. School and worked for the building of the Knights Templar School), 'Strongbow', the Earl of Pembroke (the school is built on land owned by the Earl in the medieval period), and the Knights Templar who built the parish church St. Mary the Virgin c.1125.
Recent years 
In September 2005 it became a specialist school for Sport and the Performing Arts. The school has a strong musical tradition, with about a third of all pupils taking extra tuition in an instrument or voice. The Big Band and Senior Chamber Choir perform locally and the school organises a music tour bi-annually, geared mainly towards these two groups (though anyone is welcome). Recent tour locations include Budapest in Hungary during July 2006 and Liguria in Italy in July 2008. A former pupil, Frances Balmer, won the 2004 BBC Proms Young Composers' Competition.
The Knights Templar School received coverage in the national media  in 2002 over the 'fixing' of 'A' level grades by examination boards. The school was the first in the country to appeal the grades awarded to its students in GCE 'Psychology' 
As a specialist school in sport the Knights Templar School also has a million-pound sports centre with fitness suite and a floodlit all-weather sports pitch.
Guest speakers at the school in recent years have included former politician Edwina Currie, film and television composers David Arnold and Debbie Wiseman, Cardinal Basil Hume, academic Professor Lord Soulsby, IVF pioneer Peter Brinsden, scientist Professor Sir John Polkinghorne, Professor Mick Aston from Time Team, former Cabinet Minister Lord MacGregor, actor and performer Gerald Charles Dickens, and two-times Olympic silver medallist Jonathan Glanfield. The Hoosiers performed an acoustic gig at the school in March 2011.
As of October 2012 there are 1332 pupils.
