Guangyang Secondary School has its humble origins in Kong Yiong High School which was located at Yio Chu Kang Road. However, in 1986, Kong Yiong High School was closed due to a sharp drop in school enrolment.
Guangyang Secondary School (1987–2005)
In 1987, the School Advisory Committee of Kiong Yong High School left a sum of about $60,000 which was to be given to a school that adopted its name. While the new school was being set up in Bishan, it was decided that the old dialect name "Kong Yiong" be used. Hence, the new school came to be known as "Guangyang" which is the hanyu pinyin equivalent of "Kong Yong". Thus, Guangyang, hanyu pinyin equivalent of "Kong Yiong" a government English medium school, was set up. In its early months, Guangyang Secondary shared the premises of Zhonghua Secondary School.
Reopen
The new school, costing $7 million, is a modern complex with excellent facilities. It had 28 classrooms, a library, an audio-visual theatrette, six science laboratories, two home economic rooms, an EOA room, four computer laboratory, an IT-enabled resource room, two technical workshops, a football field, a basketball court and a volleyball court, and lastly, an indoor sports hall. The school was officially opened on 27 June 1990 under the helm of her first Principal, Mr Leong Khin See. The school had her second Principal when Mrs Alice Tan Lee Huan assumed her position in 1993. Guangyang Secondary School achieved the distinction of being one of the Top 18 Value-Added Schools in the Special/Express stream. The school's third Principal, Mrs Ng-Ong Phiak Kim then took over since mid December 1996. The school was ranked as one of the Top 20 Value-Added Schools in the Special/Express Stream for consecutive 2 years. Guangyang ushers in the new year 2001 with her fourth Principal, Mrs Ngiam Geak Kim. Mrs Ngiam assumes position from 1 January 2001. She retired that same year. Miss Low Chee Moon took office as Guangyang Secondary School's fifth Principal in 2002.
