The closest I can find to a specific definition is from paper quoted in this article: http://www.srx.com.sg/ask-home-prof/20072/the-cost-of-elite-schools-in-singapore.
I assume Type 1 as defined by the paper quoted in the article are elite schools?
- Type 1 - Integrated Program (IP) schools and affiliated primary schools as well as Gifted Education Programme (GEP) primary schools.
Type 2 - students were from government-aided schools and autonomous school that don’t offer the IP
Type 3 - students were from government schools.
Just wondering if that's what everyone thinks or are there other interpretations like such as schools which are awarded MOE's SDA or SEA?
