The school experimented with upper-secondary courses in 1935. This move made Chung Ling the first institution in Malaya to provide complete uninterrupted courses for both primary and secondary education. Construction of the new campus was completed shortly afterwards. The new campus featured a grand central hall. 20 classrooms were given special names: each after the organisations and people that had donated more than a thousand Straits dollars during the donation campaign as a token of appreciation. The campus also featured modern offices for the teachers and staffs, dormitories, washrooms, dedicated courts for badminton and basketball, as well as a long athletic track, the first in Malaya. The newly built campus was the site for the opening ceremony and later track-and-field events for the Third Malayan Chinese Athletic Meet (第三届馬來亞華僑運動大會), between 2 and 5 August 1935 by the Penang Philomathic Union.

Anthropologist Lim Hooi Seong, whom previously worked in Singapore as a teacher, was appointed as provost after Chen's departure. In late–1939, he led the school to launch a nationwide campaign across Malaya for the donation of winter clothing for the war in China. For four months, starting from 9 September 1940, the school was forced to hold classes at a temporary campus at 41 Northam Road, before returning to Ayer Itam. Classes were again shifted back to 41 Northam Road in early–1941 under orders by the British government to convert the Ayer Itam campus into a makeshift military hospital. In October 1941, Lim was fired from his position by the Board of Governors. According to Lim's personal memoirs, the dismissal was political – his origins at Xiamen led the pro-Nationalist Board of
