It is mandated to open 20 slots to the public. It reserves 80 slots for its affiliated primary school.I would think otherwise. Those schools who have to open up to outsides (eg.PLMGS) would see an increase in COP because previously, their COP was artificially lowered to accommodate the affiliated students.fivefingers\" post_id=\"1947863\" time=\"1574399906\" user_id=\"45568:Want to seek opinion of parents here re the new 20% for non-affiliated. I know some schools COP will drop this year as they take in mostly their own pri students (like PLMGS) previously. Just wondering if anyone knows about schools like CHIJ St Nick or SCGS? Their COP is high for non-affiliate but I wonder if they have already started taking in more outsiders in previous years. If so, this means their COP is not \"artifically high\". My dd score 248, a bit short to go to her dream schools which are in the 250 range.
The affiliated primary school competes for the 80 slots. Hence a COP of eg 220 for affiliates is derived once the 80th student enters.
The public competes for the 20 slots. Hence, the COP of 250 for public is derived once the 20th student enters.
The COP increase or decrease is dependent on how many are competing for the slots.
By my reckoning, when MOE forces 20%, the number of slots for the public increases. Hence, for the public the COP will fall.
For affiliates, bec of this forced 20%, the number of slots decreases. So the COP for affiliates increases.
(why else will MOE force the 20% to remove stress. Bec clans were hoarding up for their own)
