[1] The school was founded in 1946 by overseas Chinese investors from Southeast Asia and elsewhere, originally in Pui Kiu Lang Park (around Happy Valley to the Mid-Levels area).

[2] When the People's Republic of China was established in 1949, the school announced that it would uphold Communist disciplines in its curriculum.

This placed a severe strain on relations between the school and the colonial Hong Kong government, as well as with the local population, whose political opinion tended towards anti-communism.

In the late 1970s, the Hong Kong government, under the education laws, took over the school and reorganized it.

Currently, Pui Kiu Middle School is part of the Direct Subsidy Scheme.
