The government often referred to Singapore's population as its only natural resource and described education in the vocabulary of resource development. The goal of the education system was to develop the talents of every individual so that each could contribute to the economy and to the ongoing fight to make Singapore productive and competitive in the international marketplace. The result was an education system that stressed the assessment, tracking, and sorting of students into appropriate programs. Educators forthrightly described some students and some categories of students as better "material" and of more value to the nation than others. In the 1960s and 1970s the education system, burdened with large numbers of children resulting from the high birth rates of the previous decades and reflecting the customary practices of the British colonial time, produced a small number of highly trained university graduates and a much larger number of young people who had been selected out of the education systems following secondary schooling by the rigorous application of standards. The latter entered the work force with no particular skills. During the 1980s, more resources were put into vocational education and efforts were made to match the "products" of the school system with the manpower needs of industry and commerce. The combination of a school system emphasizing testing and tracking with the popular perception of education as the key to social mobility and to the source of the certifications needed for desirable jobs led to high levels of competition, parental pressure for achievement, and public attention and concern.
Although education is not compulsory in Singapore, primary school is free for 6 years, and attendance is nearly universal. Some 73% of children also attend secondary school. Since 1987 English has been the language of instruction, but a policy of bilingualism requires that children also be taught Chinese, Malay, or Tamil. Institutions of higher education include the National University of Singapore and Nanyang Technological University. Of Singaporeans aged 15 and older, 100% can read and write.
