The Christians and early missionaries had indeed played a major role in public education in Malaysia, and some of the most prestigious public schools today were set up or in one way or another linked to the early Christians’ works in the country. So putting religion aside, even just for sentimental reasons, it is actually quite a sad thing to see the decline or closure of mission schools today.
But fairly, this is not, or not only, at least, a fault of the government and the authorities. The past and current Christian counterparts would have to bear an equal responsibility in this decline. What people might not know is, the Church (in this case which I am personally informed, the Methodist Church in Malaysia - can’t comment on other Christian denominations) does actually have a voice within the Federal Government in the matter of the public mission schools linked to the Methodist Church, e.g. MBS/MGS, ACS. And for many years, even in the days of previous leaders, the Church was given the right to nominate their own candidates for the role of the Principal in the schools. But few Christians would take up the responsibility, hence leaving the mission schools at the government’s mercy in appointing whoever they want to the leadership positions - and as a result, the “Christian” identity (and influence) of the schools diminishes fast. And today, the Methodist Church is dipping their toe in private education institutes themselves and it’ll be no surprise if the effort to hold on to the public schools is even lower of a priority for the Church.
And in certain Christian circles, due to one factor or another, fewer and fewer parents are inclined to send their child to public schools (missionary schools or otherwise), which while completely understandble and justified, it is for me personally quite a sad thing to see - that as Christian ourselves are not as concerned with asserting our positive influence and with contributing to the community than our forefathers were.
