We got in to HKIS without any debenture.
Do you feel HKIS has quite a few open spots? I've heard recently they dont require debenture...
The principal said debenture is not required at all. what it does is to place your kid in the highest-priority category (but if your kid does not pass their interview, a place will not be offered still. Interesting how this is different from CDIS, where debenture can only be purchased if the kid is in the waiting pool and accepted by the school.)
From what HKIS had communicated to the parents, this year there were ~400 applicants for R1 (~160 spots available). About 10% of the spots are filled up by debenture holders first, followed by ~30% by staff/alumni kids. The rest goes to everyone else.
So without debenture and connections, your odds are about ~25%...Hope it helps.
From what I hear, HKIS is quite willing to take on new students as long as they passed the assessment which is straight forward. I know a few people who tried other top schools, didn't get in.... applied for HKIS as a last resort, and they got a spot.
Tuition is expensive, so probably trying to maximize as much as possible.
I am one of those lol...
I applied HKIS along with CIS and CDNIS though and had thought HKIS is among the top rather than last resort
