Singapore Primary 1 Registration School Balloting History

(Updated 24 June 2008) Here is the consolidated Primary One Registration balloting history of Singapore's Primary Schools, since 2006.  This data is useful to parents as an indicator of the difficulty of getting their children into their preferred schools.

 

The table below describes the various possible scenarios: 

Scenario

Interpretation

No balloting necessary The number of applicants (APP) was at most equal to the number of vacancies available for that Phase.  All registrants were successful.
Cut off at 1-2km The number of applicants (APP) exceeded the number of available vacancies.  All those staying under 1km were successful without balloting.  As there was an EXACT number of applicants staying in the 1-2km range for the remaining vacancies, those staying 1-2km were also successful without balloting.  All those staying outside of 1-2km were unsuccessful.  There was no ballot.
Cut off at <1km The number of applicants (APP) exceeded the number of available vacancies.  As there was an EXACT number of applicants staying under 1km for the available vacancies, those staying under 1km were successful without balloting.  All those staying outside of 1km were unsuccessful.  There was no ballot.

Balloting required at >2km

The number of applicants (APP) exceeded the number of available vacancies.  All those staying under 2km were successful without balloting.  All those staying  beyond 2km have to ballot for the remaining vacancies.  If X% of APP were staying under 2km, then the probability of winning the ballot is (100-X)/(APP-X).  To determine X, it is necessary to check with the school sometime before the end of the days of registration for that Phase.

Balloting required at 1-2km

The number of applicants (APP) exceeded the number of available vacancies.  All those staying under 1km were successful without balloting.  All those staying beyond 2km were unsuccessful without balloting.  All those staying 1-2km have to ballot for the remaining vacancies.  If X% of APP were staying under 1km, then the probability of winning the ballot is (100-X)/(APP-X).  To determine X, it is necessary to check with the school sometime before the end of the days of registration for that Phase.

Balloting required at 1-2km
