Polytechnics in Singapore provides industry oriented education equivalent to a junior college or sixth form college in the UK. Singapore retains a system similar but not the same as in the United Kingdom from 1970–1992, distinguishing between polytechnics and universities. Unlike the British Polytechnic (United Kingdom) system Singapore Polytechnics do not offer bachelors, masters or PhD degrees. Under this system, most Singaporean students sit for their O-Level examinations after a four or five years of education in secondary school, and apply for a place at either a technical school termed ITE, a polytechnic or a university-preparatory school (a junior college or the Millennia Institute, a centralized institute). Polytechnic graduates may be granted transfer credits when they apply to local and overseas universities, depending on the overall performance in their grades, as well as the university's policies on transfer credits. A few secondary schools are now offering six-year program which leads directly to university entrance.
