Origins of the Imperial Examination System

Timeline

1. 587Daxing City · ShaanxiEmperor Wen of Sui issued an edict ordering each province to annually recommend three candidates, selecting them by examination in the xiucai category, and abolished the recommendation powers of the nine-rank system — marking the centralization of official selection authority in the capital and the germination of examination-based selection.
2. 588–595Provinces of the Sui Empire · ChinaDuring the Kaihuang era, quotas and examination standards for provincial recommendations were successively standardized; categories such as xiucai and mingjing were assessed by policy questions and recitation of classics, gradually replacing the old recommendation system of the Wei–Jin period.
3. 596–600Daxing City · ShaanxiBy the late Kaihuang years, examination-based selection and aristocratic background still coexisted, but the central government controlled the dominant role in appointment through edict-ordered recommendations; after Emperor Yang ascended the throne he further established the jinshi category, and the prototype of the imperial examination system was already clearly visible in the early Sui.
