The Oldham Methodist Secondary School merged with the Secondary School at Barker Road in January 1961. The school completed the construction of the sports complex at Barker Road in 1970, with an Olympic-sized swimming pool (the first in all the schools in Singapore) and a sports hall. In 1977, pre-university classes shifted to the newly constructed Anglo-Chinese Junior College at 25 Dover Close East, off North Buona Vista Road, leaving the Barker Road site for the secondary and junior schools. The junior school relocated to new premises in its old neighborhood at Cairnhill in 1985.
