Westerford opened at the beginning of January 1953, housed in an old homestead which no longer exists. The site was originally known as Westervoort, but the school was known as Claremont Secondary School from the name of the school which shared a property with a small primary school on Dean Street. The pupils from Claremont Secondary School initially transferred their desks to the new property at the end of 1952.
