Keystone Academy is a bilingual (Chinese–English) K–12 day and boarding school on a suburban campus in Houshayu, Shunyi District, Beijing. The school opened in 2014 and states a distinctive “Chinese Thread” that weaves Chinese culture and identity into its bilingual programme. Primary years use an inquiry-based Primary Curriculum (IPC) in a bilingual immersion model; middle and high school progress to IB programmes, with the IB Diploma Programme offered in the high school. Boarding is part of the school's model (students are required to board from Grade 9). Keystone highlights a large activities programme (KAP), an emphasis on service learning and community projects, and a strong bilingual language-acquisition focus as defining features. All factual points above are taken from the school website (see contact, curriculum, admissions and programme pages).
