St David's Prep is an independent junior school in West Wickham and Beckenham, which was founded in 1926. Its first principal was Mrs Gwenllian Davies, a graduate of Cardiff University, who was a gifted teacher and an excellent administrator. The school began in Mr. and Mrs. Davies' house and comprised just one room for a Kindergarten. By 1931 there were 32 pupils on the roll whose ages ranged from 5 to 10.
A photograph of the 1937 Sports Day shows children wearing the brown and gold blazers which are still part of the uniform for pupils today. The field was owned by the Schove family. In 1935, Mr and Mrs Davies sold the freehold premises known as St David's, as well as the scholastic fixtures and fittings annexed to the property, to Mr Derek Schove, at a cost of £900.
