This paper examines United States-Indonesian cooperation in the training of Indonesian teachers during the early decades of the Cold War. Indonesia badly needed teachers but the government's efforts to train new teachers were hampered by the tremendous lack of teachers who could train new teachers. The aid provided by the United States enabled the Indonesian government to send its prospective teachers to study in the United States and to have American educationists help develop teachers' colleges in Indonesia. How far did the decolonisation of teacher training and the making of a new education standard in postcolonial Indonesia reflect the conflicting ideological undertones and the US strategy of the Cold War? This paper argues that the US-Indonesian cooperation in teacher training marked a significant stage in the decolonisation of Indonesia. Yet, it also fostered the US cultural strategy of the Cold War in Southeast Asia.
