Score first, then choices, then vacancies, and when students tie, citizenship, choice order and the ballot decide. How the posting machine actually allocates schools.

MOE's posting pages state the hierarchy plainly: academic merit is the first criterion, and students are posted based on their PSLE results within their eligible Posting Group, their order of school choices, and the vacancies at those schools. Your child's score gets them into contention, and the six choice list you submit does the rest of the talking.
Imagine a school with one place left and several applicants on the same PSLE score. MOE resolves the tie in a fixed order, one test at a time:
The actionable line falls straight out of step two: rank the school your child actually wants first, because at the margin where places run out, having genuinely wanted the school is literally a tie breaker. One more layer applies at SAP schools: among tied applicants, better Higher Chinese grades earn priority before the standard tie breakers, covered in our Mother Tongue guide.
The whole exercise sits inside Full Subject-Based Banding, where the score also sets the Posting Group and starting subject levels, and the results week logistics are mapped here.
Every November I watch families play chess against the posting system, ranking a safe school first out of fear that aiming high wastes a choice, and the mechanics above say that instinct is exactly wrong. The system reads your list top down and rewards honesty: a miss on choice one simply moves to choice two with nothing lost, while a tie at your dream school is won partly by having dared to rank it first.
So build the list the straightforward way, the school your child truly wants at the top, realistic middle choices, and one or two comfortable landings at the bottom, all six slots used. Then let it go. The machine is fairer than the anxiety around it, it cannot punish ambition, only incomplete lists, and by mid December your child will be posted somewhere with a uniform to buy and a fresh start to imagine, which is the part they will actually remember.
No. Balloting is the last resort, used only when students vying for the last available places match on PSLE score, citizenship and choice order, so most postings resolve without any ballot at all.
Scores of 21 to 22 and 25 make a student eligible for two Posting Groups, and the choice list can include schools across both, with the starting subject levels then set by the group through which the child is posted, per the Full SBB mapping.
Affiliated primary school students enjoy priority at their affiliated secondary school when they rank it appropriately, a separate layer schools explain during the option window, so families with an affiliation should confirm the specific school's requirement before ordering their list.
