Chinese education has developed for more than half a century, and consists of a mature syllabus and system. In 2008, the 100th year since Kuen Cheng was founded, Kuen Cheng decided to convert its enrollment from all girls to a co-ed system, in order to keep up with the culture of a modern society, where males and females are viewed equally and have equal rights. In the same year, the school received its first class of male students, despite resentments from some alumni. In 2013, Kuen Cheng High School's 57th year of Higher 6 graduates became the first co-ed graduates of the school. In 2015, Kuen Cheng High School had been rated 5-stars as one of the Best Schools of Excellence in Malaysia by the Ministry of Education.
