I've never heard of this school before. I came across the NIS when I visited the Mother and Child expo the other day (btw it was a horrible expo, full of kerupuk and ikan asap seller). And I was surprised that it was actually an old establishment (from 1967). Aside from their Dutch classes, they also offer English preschool and they just started an English-language primary school in August 2006. They are situated in Cilandak and they claim that they will be the first school in Jakarta to apply the IPC curriculum (International Primary Curriculum) which will provides a smooth transition to the IB programme. Anyway, the charges are pretty steep, just like any other international school but the school ambience is pretty interesting, full of greenery and sports facilities. Check it out.
