In 2008, the school transitioned from an all-girls school to a coeducational school. There was some opposition from former female graduates who wanted the school to retain its status as an all-girls school. After becoming coeducational, the school officially changed its name to Kuen Cheng High School. The school is notable for its low acceptance rate, and only primary school students with results above a certain grade threshold are accepted. It is one of the top secondary schools in Malaysia, with 58.97% of its students scoring 5As or above in the 2019 SPM examinations.
