The designation "national first-grade museum" (simplified Chinese: 国家一级博物馆; traditional Chinese: 國家一級博物館; pinyin: guójiā yījí bówùguǎn) is the highest classification for museums in China, as determined by the State Administration of Cultural Heritage (SACH).[1]
A first-grade museum generally has a comprehensive collection of artifacts, or has a large number of items in its collection with "very high historical, cultural, scientific, and artistic value". A first-grade museum is also expected to be a social and educational institution, with a professional staff, long-term volunteers, and facilities for educational services. First-grade museums are not required to be owned by the state. State-owned museums are expected to open for more than 300 days a year, while non-state-owned museums are only expected to be open for 240 days. Performance measures for the museums are expected to be regularly published on government websites.[1]
