Hwa Chong Institution (HCI) is an independent secondary educational institution in Bukit Timah, Singapore. Formed by the merger of The Chinese High School (1919–2004) and Hwa Chong Junior College (1974–2005) in 2005, it provides secondary education for boys only from Years 1 to 4, and pre-university education for both boys and girls in Years 5 and 6. Since 2005, HCI and its affiliated school Nanyang Girls' High School have offered a six-year Integrated Programme, which allows students to skip the Singapore-Cambridge GCE Ordinary Level examinations and proceed to take the Singapore-Cambridge GCE Advanced Level examinations at the end of Year 6. Its name "Hwa Chong" ("Hua Zhong" or "华中") is an abbreviation of The Chinese High School's Chinese name, "Hua Qiao Zhong Xue" or "华侨中学".
A Ministry of Education-designated FutureSchool, HCI operates under the Special Assistance Plan (SAP) for bilingualism, and offers the Integrated Programme and the Gifted Education Programme. HCI has been a top feeder school for international students to the University of Oxford and University of Cambridge. The institution is also a member of Strategic Alliance of Global Educators, Strategic Educational Alliance of Southeast Asia and the Global Learning Alliance which involves some of the world's most innovative schools from the highest performing nations, including Australia, Canada, China, Finland, New Zealand, Singapore, Sweden, and the United States. HCI has also forged partnerships with educational institutions across five continents, including cross-border research collaboration with the Loudoun Academy of Science in Virginia and Westport Schools District in Connecticut.
