In 1970, Mr Chee Keng Lim took over from Mr Lee Hah Ing as principal
of the secondary school on the latter's retirement. The School's
enrolment saw an increase from 2090 in 1970 to 2445 in 1976. The
number of classes rose from 52 to 59, including 7 Pre-U One classes
and 6 Pre-U Two classes.
With the Singapore Government's move to encourage the building
of junior colleges, the ACS OBA, with the support of the Board
of Governors, established the Anglo-Chinese Junior College (ACJC)
Building Fund. The site at Rochester Park, off Dover Road, was
allocated for the building of ACJC. Through several fund-raising
drives, more than $5 million was raised. In 1977, ACJC opened
its doors to 600 Pre-U One students and the 287 Pre-U Two students
who had completed their Pre-U One course at the Barker Road campus.
With the extra classrooms available as a result of the move by
the Pre-U students to ACJC, the Secondary School increased its
number of classes to include at least 10 classes per level.
In 1985, the Anglo-Chinese Junior School, which had previously
been functioning in the same campus as the secondary school in
Barker, Road moved to its new premises in Cairnhill in 1985.
