Cranmer was not always a primary school. It started life as a grammar school; the Mitcham County School for Girls opened on May 2nd 1929. Cranmer became a Middle School in 1969.  Then in September 2001 Cranmer became a two-form entry primary school with a 52-place nursery. Present-day pupils benefit from the wonderful Grammar School building and facilities. There is no evidence of any historical link with Archbishop Thomas Cranmer. Cranmer would appear to be named after the Cranmer family who were Lords of the Manor of Mitcham since 1656.  Robert Cranmer, who was a Merchant trading with the East India Company, bought the land in 1656. A grand house called “The Cranmers” stood on the site of the current Wilson Hospital, but it was demolished in 1928 to make way for the Hospital.  Beside the house was a timber-framed tithe barn; this was demolished at the same time. Mitcham County Grammar School was built in 1928-9; the wooden beam in Cranmer’s old reception area is said to have come from the tithe barn. 

In 2010 Cranmer was asked to expand from a two-form to a three-form school due to the high standards of education we provide. In September 2010 we took in our first cohort of 90 pupils. After consultation with stakeholders at Cranmer, we decided to expand and create a purpose-built upper Key Stage 2 building (Cranmer Court ) alongside our existing building  (Cranmer Crescent).
