It includes both group and individual interviews.
Group interview- teacher told a story and sang a song. There are around 2 to 3 teachers observing kids' responses and marking down the comments.
Individual - A NET asked parents lot of questions. Who take care of child ? What language do the family speak to the kid at home ?
Any siblings? Where are they studying ?
It's really a good school which can provide good bilingual environment!
BTW, last year when we had the interview, the result was posted to us 3 days after the interview! So they're very efficient! And I know that they did accept many "small b" last year!
