教判(教相判釋，又稱「判教」)思想之發達為中國佛教的特色之一。自南北朝起，諸家判教之說紛起，而為天台智者大師歸結有「南三北七」十家之多。智者之介紹眾家異說，固是為評難其得失之後，展現天台教判之完備適洽，所陳各家之主張，亦實為了解與研究當時之判教思想的重要文獻依據。而天台宗本身亦可說是收納各家之長，最先提出完整周備而恢宏謹嚴之教相體系，成為中國最重要而具代表性的判教思想之一者。本文之旨，除在由之一窺南北朝各判教思想之大要外，亦主在究明智者如何論斷各家之說，進而展立其自身之判教體系。

　　　　　The 'division of the Buddha's teachings' is a special characteristic of Chinese Buddhism. From the period of the Southern and Northern Dynasties the development started and culminated with Master Chih Che's teaching of the 'southern three, northern seven' schools. There were different explanations of Master Chih Che's thought. After a critical study of them, he chose the most appropriate schools to fit in with Tien Ta thought. He strove to understand and research the important literary contributions of the divisions of the time. The Tien Tai School could be said to have strictly incorporated the divisions of the time into a more systematic teaching. By doing this, they created an important and representative philosophy of the divisions in Chinese thought. This article wishes to take a look the 'divisions of Buddha's teachings during the Southern and Northern Dynasties. It would also like to investigate Master Chih-Che's treatment of the different schools and look at how he systematized them.
