Here's an extract :
Getting endorsed as an active Community Leader
"Active Community Leaders" are defined as current serving executive committee members of the Residents’ Committee (RC), Neighbourhood Committee (NC), Citizen’s Consultative Committee (CCC), Community Club Management Committee (CCMC) and the Community Development Council (CDC).
Join the RCs if you are in public housing (heart-landers), and NCs for private housing (no heart-landers like condo-landers/house-landers/own-landers).
Most importantly, make sure your target school is in the GRC that your RC or NC is serving in! You may check this by referring to this link. Please double check especially during pre-election years because GRC boundaries tend to "change".
When you first join, you will be registered as an Observer and you must be an active participant for at least 3-6 months before you are granted Executive Member status. You must be an Executive Member before you are given a chance to request for a letter signed by your MP to endorse you as an active community leader for priority registration in Phase 2B.
There is some debate on whether you need to be active for at least a year before you can be granted Executive Member status. What is certain, however, is that you must be prepared to be very active in all the meetings and activities of the RC and NC for a block of 3-6months.
In general, if you do not like your neighbours or doing community work, I would recommend that you do not go this route. You will be spending a lot more hours than PV, and it is not politically correct for you to do community work just because you want to get your child into a school you desire.
Here is the forum thread where parents share their experiences in being active community leaders.
