Under the Tang, six categories of regular civil-service examinations were organized by the Department of State Affairs and held by the Ministry of Rites: cultivated talents, classicists, presented scholars, legal experts, writing experts, and arithmetic experts. Emperor Xuanzong of Tang also added categories for Daoism and apprentices. The hardest of these examination categories, the presented scholar "jinshi" degree, became more prominent over time until it superseded all other examinations. By the late Tang the jinshi degree became a prerequisite for appointment into higher offices. Appointments by recommendation were also required to take examinations.
