I notice that in the recent evaluation of first-rate universities and disciplines in China, no colleges of vocational education are granted the honor. But I learn from other sources that such colleges are the integral part of higher education of this country, which have outnumbered the traditional colleges that offer four-year long undergraduate education.
They say such colleges were changed from the former secondary schools of vocation, so that they are simply 大专, not 本科. But I understand that all colleges are known in Chinese as 大专院校, so what is the difference?
