Notice to Improve
The school opened in 1962 as the Teddington Secondary School, a single-sex school, taking over the senior boys of Stanley Road School when it ceased to cater for the full age-range, as well as the boys from Twickenham Technical School. Pupils from the former St Mark's School in St Marks Road joined Teddington School in April 1963.
From the late 1960s to the mid-1980s it was called Teddington Boys' School, the name being changed to Teddington School on the admission of girls in 1985 for the first time. The school's uniform colours during this period were black and red, with a school blazer badge displaying a swan upon a green background, the coat of arms of the County of Middlesex and a gold lion rampant on a red background, with the motto in Latin Meret Qui Laborat beneath. [Note 1] In the 1960s, the six houses were Bannister, Faraday, Brunel, Lovell, Churchill and Fleming. 
In 2010 under a central government public works programme entitled Building Schools for the Future, the original mid-20th Century design school buildings on the Broom Road site and its attached hardcourt sports fields of an athletics field, football pitch and tennis courts, were demolished, and a new school building and sports' ground were constructed by the builder Mace Group Limited at a cost of £36 million. The school was also re-branded at this time with its uniform being fundamentally redesigned to a teal and grey colour scheme and a kingfisher bird emblem.
The school has run an exchange programme with German School Geschwister-Scholl-Schule School in Konstanz since 1976.
