In 1104, the prefectural examinations were abolished in favor of the three-colleges system, which required each prefecture to send an annual quota of students to the Taixue. This drew criticism from some officials who claimed that the new system benefited the rich and young, and was less fair because the relatives of officials could enroll without being examined for their skills. In 1121, the local three-college system was abolished but retained at the national level. For a time, the national examination system was also abandoned in favor of directly appointing students of the Taixue to government posts. The Taixue itself did not survive the demise of the Song dynasty and ceased to exist afterwards, becoming a synonym for the Guozijian.
