Post-secondary相当于“高等教育”.

　　用汉语里的对应概念粗略总结一下：

　　幼儿园、托儿所、学前班=pre-school/nurseryeducation

　　小学、初中=primaryeducation(初中也有归到secondaryeducation的)

　　高中=secondaryeducation

　　大学,学院=post-secondary/highereducation

　　一般primary和secondaryeducation是义务(compulsory)教育,学习“常识”(commonknowledge).Highereducation学习专业/职业知识.
