hi Harriet,
I'll attempt to clear your doubts :
Phase 2B is for a child whose parent has joined the school as a parent volunteer in *June (of the year before you are due for P1 registration) and has given at least 40 hours of voluntary service to the school by July of the year of registration; (*For e.g., for my case, I will register for P1 for my gal next year, so I will need to be a parent volunteer by June this year). or whose parent is a member of the church/clan directly connected with the school; or whose parent is endorsed as an active community leader.
Phase 2C for a child who is ineligible for or unsuccessful in earlier phases.
The number of places in phase 2B and phase 2C are the same; after all the available places for a school is taken up in the earlier phase 1 to phase 2A2, whatever places remains in the school will be divided equally for phase 2B and phase 2C.
However, as you could see from above, the group who could register in phase 2B would be smaller than the group who would register in phase 2C (note: phase 2C is basically opened to all). So most parents will get themselves into phase 2B to increase their chances of getting a place in the school.
As for distance considerations : if the places that are available under phase 2B is less than the number of registrants, then allocation will be based on the proximity of your home from the school. So, in this regard, the advantage (priority) will be given to those who stay within 1km from the school.
Works the same way for phase 2C.
So, in other words, the distance you stay from the school, actually does not determine which phase you could register.
Hope this helps to clariy. Feel free to ask if you are not clear
Cheers.
