Goh won a scholarship which enabled him to further his studies at the London School of Economics and Political Science (LSE). During his time in London, Goh met fellow students seeking independence for British Malaya, including Abdul Razak (later Malaysia's second Prime Minister), Maurice Baker (subsequently Singapore's High Commissioner to Malaysia), Lee Kuan Yew and Toh Chin Chye. A student discussion group, the Malayan Forum, was organised in 1948 with Goh as the founding chairman. Goh graduated with first class honours in economics in 1951, and won the William Farr Prize for achieving the highest marks in statistics. Upon his return to the Department of Social Welfare, he was appointed assistant secretary of its Research Section. In 1952, together with fellow civil servant Kenneth Michael Byrne, he formed the Council of Joint Action to lobby against salary and promotion policies that favoured Europeans over Asians. Byrne later became self-governing Singapore's first Minister for Labour and Minister for Law.
