Hikaru no Go Wiki

A go apprentice (院生, Insei) is a student learning to play Go at an institution, typically with the aim of becoming a professional player. In Japan, such a student is called an insei (literally, "institution student"). Institutions for insei include the Nihon Ki-in (Japanese Go Association) and the Kansai Ki-in (Kansai Go Association). The equivalent of Go insei in Korea is "Yeon'gusaeng" (Hangul: 연구생; Hanja: 硏究生), read "kenkyūsei" in Japanese and "yán jiū shēng" (also meaning "graduate student") in Chinese.



To become an insei the person must be at least strong to become one and the average player can not pass the test easily. Another thing is if a person wants to become insei, they have to quit their go club if they are part of one, since insei are not allow to play in amateur tournaments.
