In addition to general programmes, junior colleges also offer several types of special programmes (e.g. advanced specialist or customised programmes) but these represent less than 10% of junior college enrolment. But following a previous period of expansion, the number of junior college students has been falling over the past ten years, in particular in the fields of science and engineering (Kim, Woo, Ryu, Oh, 2011). The number of junior colleges has also fallen from 158 in 2005 to 145 in 2010 (MEST, 2010). Almost 95% of junior colleges are private (136 out of 145) and enrol about 97% of over 767 000 junior college students.
