新加坡有两种学校类似于中国的高中：初级学院（简称初院，Junior College）以及高级中学（简称高中，Centralised Institute），其中包括综合课程的初院和高中。这两种提供大学预备课程的学校是新加坡教育制度中提供高中教育的学府。现在新加坡共有18所初级学院和1所高级中学提供大学预备教育课程。大学预备课程教育分为理科与文科，初级学院的商科已于2000年被废除。如今，励仁高级中学是唯一提供商科的大学预备课程学校。
新加坡的中学生在中学4/5年级参加了新加坡剑桥普通水准考试（GCE 'O' Level）之后，便可以选择进入初级学院或者高级中学学习高中课程。
After taking the O-level national exams, most secondary school students will move on to a poly or a junior college (JC).
