I can't remember exactly how long it took for them to call me back. But I did remember registering online at least 1 year earlier.
When I did not hear from them, I called them to check. I was then informed they will collate all registration & call selected ones for registration (based on born year of your child, ie 2011-born for next year Nursery or 2012 infants for next year Infant Care).
All I know the quota for Infant Care is very small (cos they exercise small ratio of teacher to infant) while Nursery & Kindergarten quota bigger (2 classes each).
How old is your child TLCP? If you're staying opp the blk, shouldn't it be easier to those living nearer? Maybe you would like to call & check if there is still vacancy left?
